What is the Downside to Fiberglass Pools? 3 Myths & 3 Truths

Posted on February 23, 2022June 15, 2026 by krista

If you are considering an inground pool, you will quickly realize that much information is available. You will likely first consider what type of pool is right for you as you compare the three different inground pool types. Looking for the pros and cons of fiberglass pools vs. concrete or vinyl liners can help you narrow down your preferred pool type. If you’ve already narrowed it down to fiberglass pools, you may even have Googled, “What is the downside to fiberglass pools?” or “How long do fiberglass pools last?” to see what results you may get. (Smart move). Though it may seem odd that a fiberglass pool manufacturer is addressing this question, it would be even more strange to pretend that a fiberglass pool is for everyone. Everyone should buy the best pool type for them, so this post will address some myths and truths about the downside to fiberglass pools.

What are the perceived negatives of a fiberglass pool?

Myth 1: Fiberglass pools are slippery.

Between the clear water shimmering in the sun and the high-gloss finish of a fiberglass pool, it’s logical to think it’s slippery. However, over the years, technological advances have resulted in a gelcoat finish for fiberglass pools that is smooth but non-skid. Fiberglass pools are comfortable on your feet (and your pet’s paws), will not snag your suit, and they aren’t slippery. But of course, anywhere there’s water can cause accidents to happen, so always be careful when entering and exiting or walking around any pool type.

Myth: Fiberglass pool designs are “slim pickins.”

Some people assume fiberglass pool designs are punched out like widgets because they are manufactured in a controlled environment and shipped to the site. Go back a few decades, and there indeed were fewer options. However, today, fiberglass pools come in an array of sizes, shapes, and colors. Fiberglass pool manufacturers like Thursday Pools are constantly innovating to provide new options and built-in features, such as beach entry pools (Patent US 10,472,839).

Myth 2: Fiberglass pool designs are “slim pickings.”

While fiberglass pools are manufactured from molds in a controlled environment and shipped to your site, there are many options. Go back a few decades, and that wasn’t the case. However, modern fiberglass pools come in an array of sizes, shapes, and colors. Thursday Pools is constantly innovating to provide new options and built-in features to our fiberglass pool shells and was first on the scene with beach entry fiberglass pools (Patent US 10,472,839).

Myth 3: Fiberglass is weak and brittle compared to other pool types.

Don’t be fooled by the name—fiberglass is not fragile. In reality, fiberglass is incredibly strong and flexible, making it highly resistant to cracking and wear. Fiberglass pools withstand shifts in soil and ground movement, making them durable in varied climates. A testament to their durability, fiberglass pools can last several decades when properly maintained.

What are the negatives of a fiberglass pool?

Truth 1: Fiberglass pools aren’t customizable in terms of size and shape.

Because they arrive on site in one piece, and the Department of Transportation limits what can be hauled down our roads without tighter regulations and a more extensive approval process, fiberglass pools are typically only 16 feet wide. So, fiberglass may not be for you if your pool must extend beyond 16 feet wide or 40 feet long. You also can’t get a fiberglass pool shaped like a guitar (unless a fiberglass pool manufacturer adds it to their design lineup).

Truth 2: The initial cost may be higher than other pool types.

It will likely cost more upfront to purchase a fiberglass pool than some other pool types. However, because you’ll save on maintenance and there is no liner to replace, the lifetime cost of a fiberglass pool is typically lower. So, if you need to spend less upfront, fiberglass may not be your best option. Check out our Pool Cost Calculator if you’d like a ballpark estimate for a fiberglass pool.

Truth 3: It’s not a DIY project.

A fiberglass pool is a lifetime purchase, but that’s only true if properly installed. A DIY installation voids the pool’s warranty. In any case, we wouldn’t recommend that the average homeowner, or even an above-average DIYer, attempt to install a fiberglass pool. That’s one reason we don’t sell directly to the general public. An experienced pool builder should install a fiberglass pool to prevent horror stories like the pool popping out of the ground or damage to the pool or house from trying to position the pool.

More Research Options

Check out YouTube, Pinterest, Houzz, and fiberglass pool reviews if you want more research options. Use our online resources, such as our “Everything You Need To Know About Fiberglass Pools” page. Or talk to an independent dealer. Consider what questions you might ask them in advance. Questions for a pool builder might include: Do they have a warranty? What type of pool is their specialty? What is their lead time, and what does their installation schedule look like? What pool shapes, sizes, and design options do they offer? What about financing?

There are advantages and disadvantages to fiberglass pools, so it’s essential to determine what you are looking for in your swimming pool to make the best decision for your and your family’s needs. Hopefully, this article has aided your decision, as fiberglass pool regrets are the last thing we’d want a pool buyer to experience.

What Type of Pool is Easiest to Maintain?

Posted on February 7, 2022June 15, 2026 by kristin

What type of inground pool is the easiest to maintain? Is it concrete (gunite)? Or vinyl? Maybe it’s fiberglass? It’s an important question for the prospective pool owner. Maintenance is part of the budget and the pool lifestyle. The pool maintenance conversation is interesting in that the pool types that require the most maintenance require the most explanation. That’s not meant to scare you away from something you have your eye on, but to let you know what to expect when it comes to the time and financial resources you will pour into your pool once it is purchased.

The variety of pool types exists for a reason. Each leverages different materials and technology toward specific purposes. Fiberglass is unique and manufactured in a controlled setting and then shipped as a unit to its site. Concrete can be very custom, is built on site, and can be quite expensive. Vinyl is also built on site, but it is relatively inexpensive to install. Let’s review the pluses and minuses of each pool type and then talk about where maintenance fits into the purchase decision for different buyers.

For this conversation, we’ll assume you are an inground pool buyer. Above-ground pools are part of the pool market, of course, and they are incredibly inexpensive by comparison, but they typically do not last as long. In addition, the experience they offer is very different from an inground swimming pool. We’ll discuss concrete, vinyl-lined, and fiberglass inground pools, and we’ll order that discussion from most maintenance to least maintenance.

Concrete (Gunite) Pool Pros and Cons

Concrete pools allow for customization and creativity. They offer the most flexibility of all pools, allowing the buyer to choose the look, feel, shape, depth, size, and features. The concrete pool surface is typically rough, and as a result, can snag swimsuits and scrape kids’ feet and dogs’ paws. The cost can be higher, ranging from $50,000 to $120,000 and up. Concrete pool costs vary broadly based on customizations and region of the country.

Concrete pool maintenance is the most involved of the three types of inground pools. The surface’s porosity welcomes algae, and algae is tough to get at. It typically requires a weekly scraping with a steel brush to get in those nooks and crannies. To stem the algae problem, you’ll probably need a professional cleaning every three to five years for around $500. To protect the surface, you’ll also need to resurface it every 12 to 15 years for approximately $7,000 per 1,000 square feet.

Water chemistry is essential for all pools. It takes extra vigilance to ward off algae and salt, calcium and other minerals with concrete. This care generally requires filtering twice a day, therefore paying a little more in annual electrical costs. Most concrete pool owners will need or choose to hire a professional to open, close, or do a thorough cleaning each year, as well.

The average concrete pool owner can expect to perform around 4-8 hours of maintenance per week.

Vinyl Pool Pros and Cons

Vinyl pools also allow for a certain amount of creativity. Vinyl-lined pools can feature ledges, sitting benches, and the like. But the surface is slippery and not as conducive to these features as other types of pools. The soft vinyl surface is prone to ripping and punctures by everything from dog claws to sharp objects dropped in the pool to fallen tree limbs. Vinyl pools are relatively quick to install and, at around $25,000 to $65,000 on average, these pools are the least expensive of the three in upfront costs.

Vinyl-lined pool maintenance is not as extensive as concrete, and you certainly won’t be using a steel brush on its more delicate surface. Your level of care will depend in part on how much you use it and how proactive you are with regular maintenance. Its propensity to rip can result in the need for patching and or liner replacements. Liner replacements can be a $3,000 to $7,500 investment every five to seven years. If water chemistry isn’t carefully maintained, the liner may need to be replaced more often. The seams of a vinyl pool can also collect algae, keeping your regular chemistry costs about double to fiberglass. With a vinyl pool, you can save a little money by filtering one time per day and using fewer chemicals than you would with concrete, and you may not need to hire a professional as often as you might with a concrete pool.

The average vinyl-lined pool owner can expect to perform around 4-6 hours of maintenance per week.

Fiberglass Pool Pros and Cons

Fiberglass today provides the best of both worlds. Like a vinyl pool, it is quick to install—quicker in that it comes as an entirely manufactured shell ready to be dropped into an excavated backyard spot. While not as customizable as concrete pools, the breadth and creativity of the modern fiberglass pool far surpass the expectations of many first-time pool shoppers. The upfront cost of a fiberglass pool is usually a little more than vinyl and a little less than a comparable concrete pool, ranging from $45,000 to $85,000 on average.

Fiberglass pools are the most durable of the three. The attractive gel coat that seals the surface of the thick, multilayered fiberglass material resists fading and damage. There are no seams and pores to collect algae, so that alone saves on chemicals and quite a bit of time scrubbing.

Fiberglass pools require fewer chemicals and less filter circulation, even with cutting-edge features like tanning ledges. If a concrete pool can cost close to $700 annually for chemicals and around $600 for electricity related to the filtering, a fiberglass pool should run about a third of that cost. And, you do not need to acid wash the surface every three years as you would with concrete.

The average fiberglass pool owner can expect to perform around 1-2 hours of maintenance per week.

Long story short, the type of inground pool that is the easiest to maintain is clearly fiberglass. If you want an even more in-depth comparison of vinyl vs concrete vs fiberglass pools, check out our comparisons of inground pools.

What Are the Main Problems with Fiberglass Pools?

Posted on February 1, 2022June 15, 2026 by kristin

While fiberglass pools are elegant, have loads of built-in features, are recognized in the industry as the lowest maintenance option available among pool types, and last a very long time, we understand why some may still ask, “what are the main problems with fiberglass pools?”. An inground pool is a significant investment of time and money, and potential pool buyers want to know if they will be happy they chose a fiberglass pool in the end—after all, no one wants to experience fiberglass pool regrets.

We applaud you for looking into it. Searching for possible negative aspects will bring perspective and prepare you to be a more informed pool buyer because:

It helps dispel common misperceptions of fiberglass pools.
It clarifies the type of care and quality you should expect from manufacturers and installers.
It sets realistic expectations for annual and ongoing maintenance.

Let’s review common questions related to what people think are the main problems with fiberglass pools and weigh the validity of the concern.

Is a fiberglass pool worth the money?

This question often comes from perceptions based on dated or unlikely occurrences. The top three perceptions we hear are:

A fiberglass pool is thin and flimsy and will crack easily.
A fiberglass pool is prone to separating from its deck, bulging, or even popping out of the ground.
Last is the belief that there are too few design options with fiberglass pools.

The first perception is related to an outdated image of fiberglass pools. They aren’t what they used to be, and that’s a great thing. Not everyone is familiar with the advances in fiberglass pool manufacturing and installation, which make fiberglass pools incredibly durable and exponentially increase their lifespan. If you’re new to modern fiberglass pools, it’s probably worth your time to investigate the construction and design innovation that’s helped fiberglass to grow so popular.

The second perception is a case of the exception obscuring the rule. You may have read or heard a horror story of a fiberglass pool installation gone wrong, and yes, incorrectly installed fiberglass pools (or any pool type) can fall victim to hydrostatic pressure and come out of the ground if not properly installed. Unforeseen problems like this are why it is important to leave fiberglass pool installation to pool builders and not attempt to tackle it as a DIY project. Additionally, there are innovations out there to help combat these concerns, such as our Geo-Anchoring Pool System that anchors the walls to the earth so they resist movement or bulging of the pool walls.

The third perception usually comes from either first-time pool buyers or those with fiberglass experiences from decades ago when in-ground fiberglass pool design options were far more limited than today. If you imagined an oval or rectangular bowl with a metal ladder hanging over one end, you’d be pleasantly surprised by the shapes and options available with fiberglass. The fiberglass pool industry has flourished with accessible and affordable innovations in designs. High-end features like tanning ledges, beach entries, wrap-around bench seating, and swim-outs are built-in. Modern fiberglass pools provide a custom look and feel without the custom expense of some other pool types. However, you are limited to the designs offered by the fiberglass pool manufacturer. Customizing the pool shell itself isn’t an option, and sizes are often limited to no bigger than 16 feet wide due to shipping restrictions. Depending on what you’re looking for in your pool project, these may be potential disadvantages of fiberglass pools.

Will my inground fiberglass pool come with built-in issues?

Any pool can develop leaks and warping if poorly manufactured or installed. Expertise is vital at the manufacturing, transport, and installation stages to prevent issues like these from arising. When you own a pool, damage due to improper maintenance might be in your hands. However, before you can take your first dip, your pool is in the hands of others.

Check if the fiberglass pool shell manufacturer uses the most durable materials and technologically advanced manufacturing methods. Following industry-recognized standards, like ISO 9001, for quality and safety can indicate a quality manufacturer. Some fiberglass pool shell manufacturers have experienced problems keeping up with production, which is a potential fiberglass pool problem for some. However, Thursday Pools has continually reinvested in expanding our capabilities, enabling us to maintain highly competitive turnaround times.

Can you repair a fiberglass pool?

Yes, you can, but we don’t recommend doing it yourself. It may be tempting to take matters into your own hands and start looking into a fiberglass pool repair kit should issues arise. Unfortunately, certain materials and tools are unsafe for a fiberglass pool’s finish if used or not used correctly, and it’s best left to professionals. The more significant point to remember is that it’s rare that you should need repairs if you properly maintain your new fiberglass pool.

Fiberglass pools are incredibly durable and are known for being lower maintenance than other inground pool types and may last for many years. Lower maintenance does not mean no maintenance, though! Maintenance is an important part of owning a fiberglass pool. As with any inground pool, it is vital to follow the manufacturer’s recommended care instructions to ensure the quality of the pool is maintained. Proactively maintaining proper water levels and chemical balance, cleaning filters, and basic upkeep prevent problems with fiberglass pools.

How Much Does a Fiberglass Pool Cost?

Is a Fiberglass Pool Right for Me?

Posted on December 23, 2021June 15, 2026 by krista

An inground swimming pool is a significant, long-term investment, homeowners should weigh their options carefully and choose the type of pool that will fit their needs for as long as they own their home. We know it’s tempting to just go with the pool type you can get the soonest—resist the urge! Fiberglass pools are an inground pool option that is both worth the wait and fits a wide array of buyers’ lifestyles. You may have questions: Is a fiberglass pool worth the money? How long do fiberglass pools last? What is the downside of fiberglass pools? In this blog post, we’ll discuss fiberglass pools pros and cons.

Fiberglass Pools Pros and Cons

The Pros:

Design Options. At one time, fiberglass pool design options were limited. Modern fiberglass pools come in various shapes, sizes, and colors that complement any backyard design. Go sleek and contemporary or free-flowing and laid back – there is a design and size for every situation. You can easily customize them with tilework that matches your personality and aesthetic.
Built-in High-End Features. Fiberglass pool shell designs include some of the hottest trends in inground pools. Depending on your chosen model, many desirable and artful features like tanning ledges, swim-outs, and wrap-around benches are built-in. Elements once considered only for the realm of resort pools, like beach entries (zero entries), are now built into fiberglass pools.
Smooth, Non-skid Finish. Concrete (gunite) inground pools tend to have a porous, rough finish, and vinyl pools are often very smooth to the touch but can become slippery when wet. With a fiberglass pool, you have a gel coat finish that looks polished and shiny but is non-skid and non-snag! Of course, any pool type can pose a fall risk, so always be careful as you enter and exit the pool!
Durable. Don’t be fooled by the “glass” in the word fiberglass. While not all fiberglass pools are equal, we build Thursday Pools fiberglass pools with nine layers of strength, with both the structure and surface lasting for decades with less maintenance required than other pool types. Non-porous fiberglass inhibits algae and other minerals that break down other pool-type finishes. Whereas a vinyl liner typically needs to be replaced every eight to ten years on average and a gunite pool needs replastering after 10 to 15 years on average, a fiberglass pool can last a lifetime with proper pool maintenance!
Lowest Maintenance. It’s generally accepted that fiberglass pools have the lowest maintenance cost of all three pool types. A fiberglass pool’s ten-year maintenance costs could be around $5,750 on average, whereas other pool types maintenance costs can be much higher. A big part of long-term gunite pool maintenance costs involves steel brushing the surface every week, acid washing an average of every three to five years, and resurfacing an average of every 10 to 15 years. For vinyl liner pools, replacing the liner every five to nine years or so will need to be factored into maintenance cost plans. Because there is seldom a need to resurface fiberglass, and fiberglass pools require fewer chemicals, you can anticipate lower maintenance costs over the pool’s lifetime.
Quick to Install. Vinyl and gunite pools are built on-site and are subject to the elements and potential delays that inclement weather brings to construction projects. Fiberglass pools are constructed in a controlled factory environment. When it arrives at your home, it is ready to be put into place. The process can occur in as few as three weeks during non-peak seasons. Compare that with concrete pools that typically take three to six months to install and vinyl liner pools that could take six to eight weeks.
Pet-friendly. Concrete inground pools can be rough on your pet’s paws, and vinyl inground pools can be slick, causing slips or tears when they come in contact with pet nails. The durable, non-skid surface of fiberglass resists scratches and tears from toenails and prevents slipping when your pet attempts to get out of the pool.
Increased Home Value. As home resale value varies by location and condition, a home with a pool’s resale value also varies by type of pool installed. Because of the lower long-term maintenance costs, fiberglass pools tend to be preferred by homebuyers and can increase the value of your home.
Environmentally More Friendly. Non-fiberglass pools can leach chemicals and rust back into the groundwater. And acid-washing can result in harm to the environment. Fiberglass pools don’t pose these types of environmental problems. If you go with a fiberglass pool manufacturer committed to the environment, you are taking steps to contribute to a greener world.

The Cons:

It’s not a DIY Home Project. We recommend that an independent dealer installs your fiberglass pool. If you go with a non-licensed installer, the performance and durability of your pool can suffer. With a DIY approach, you may not get to enjoy your pool until you fix all the mistakes. Common problems people have when trying to install a fiberglass pool on their own are getting the pool level and pouring coping around the fiberglass pool. These can be expensive errors to correct.
Size Limits. Gunite and vinyl pools are built on-site, so there is flexibility if you want to go big with your pool. One of the disadvantages of fiberglass pools is that they are generally limited in size and shape by what can be transported from the factory to your backyard. Road restrictions limit the size of a fiberglass pool to approximately 16′ wide x 40′-41’ long.
Customizability. Fiberglass pool designs are surprising in their breadth of features and shapes, but they are pre-built, so the manufacturer’s parameters can limit you. For example, if you have your heart set on building a guitar-shaped pool, you’ll likely need to look into gunite. Additionally, if the fiberglass pool design you want comes with a tanning ledge that you don’t want, you will also need to look at another pool type.
Access/Space for Installation. Because we transport a fiberglass pool shell in one piece to your backyard, you must have backyard access and space. Installers often use cranes and other heavy equipment to get the pool to its destination and this need for access and freedom to move a large object can be a dealbreaker.

A fiberglass pool is not for everyone, but we still believe there is someone for every Thursday Pools fiberglass pool. Knowing fiberglass pool pros and cons is a step toward finding your fit. Check out our Pool Selector Tool to find your match or get started with an estimate.

Fiberglass Pool Reviews

Posted on December 7, 2021June 15, 2026 by krista

When you begin the process of considering a backyard pool, your mind might swirl with questions. You may start with basic questions like, “how much do fiberglass pools cost?” Or, “is a concrete pool or fiberglass pool better?” You should look for reliable information and answers to your questions from people who have already taken the plunge. In this post, we’ll give answers to three common questions pool buyers ask and throw in some fiberglass pool reviews of our own.

Are there many fiberglass pool designs to choose from?

Yes! Over the last 30 years, fiberglass pool manufacturers have taken customers’ most loved inground pool features and designed them into the fiberglass pool shell. When comparing fiberglass vs vinyl pool cost or fiberglass vs concrete pool cost, you should factor in the features because many that are built into fiberglass pool designs may add to the cost of other pool types. Some features you’ll find in Thursday Pools designs include benches and seats, beach entries (aka zero entries) (Patent US 10,472,839), swim outs, built-in steps, tanning and safety ledges.

We just finished the install of our Thursday Pools pool. We chose the 16×33 Goliath for its design to allow lap swimming end to end. We love the multiple sets of stairs and safety ledge on each side. The California finish color looks amazing!! Quality construction!!! Highly recommend. -Eric Demaline

Their beach entry pools are amazing! We love ours, and the beach entry is perfect for pets and children! Thursday Pools has always been a pleasure to work with ☀️” -Bonnie Sommers

We love our new pool! Fiberglass is definitely the way to go!!! -Julie Sue Upchurch

Can I get a small fiberglass inground pool?

Good news! Thursday Pools has a variety of pool sizes to fit your backyard oasis. Perhaps you have a small yard or simply don’t want a large pool. Regardless, if you’re looking for a small fiberglass inground pool, you have options for fiberglass pool shapes and sizes with all the popular features of larger pools. Let’s look at some.

What’s the difference between fiberglass pool manufacturers? Sunday is Funday, swimming in our … Sun Day Fiberglass pool, not only Sunday but everyday we spend is a funday with Sun Day. We lounge on the sun shelf, use the wide open steps with the top one the best for our 2 year old Ava. We love the bench seats with the water spa jet returns flowing the crystal clear water. After just two days after the pool was filled we were amazed how quickly the water warmed up, the fiberglass holds heat and even at night the water remains warm. We have already had a pool party and everyone comments on the design and how beautiful the water looks. we just love our new pool and no need to take a summer vacation, just walk out the door. A special thanks to Justin and all the great staff at American Pool and Spas in Richmond, KY, from start to finish their work was professional. …yes everyday is Funday…thanks! -Will and Ashley Mason and Ava Sheets, and Bruce and Kathy Markley

While we can’t speak for the competition, we can tell you what we think makes us stand out. Thursday Pools believes that passion, care and attention to detail makes the difference. This includes our work with strategic partners, dealers and homeowners. Our pools are hand-crafted by skilled artisans in a factory-controlled environment and are built with multiple layers of strength. We are committed to innovation, quality and the environment.

I spent the winter traveling the country and kicking the tires on several fiberglass pool manufacturers. I’ve been installing auto covers for 15 years, and I have worked on every pool out there. It was time to take it to the next level with my company. I chose Thursday Pools over everything else for several reasons. The main reason I chose Thursday Pools is due to the engineering details that they have pioneered and patented. Geo-wall to anchor the exterior of the pool to the Earth, beach entry pools (Patent US 10,472,839), and pool shells that are tailored to accommodate an automatic pool cover are a few of the most important reasons for me. After I got to meet the owners of Thursday Pools and got a feel for who they are as individuals, we can’t help but to love these guys. Best decision we could’ve ever made was to choose Thursday Pools to be our manufacturers exclusively. -Josh Welsh

Great build quality and knowledgeable staff. Purchased a Titus 14×33 and absolutely love it! Shopped other manufacturers before looking at Thursday Pools. 100% happy with our decision!

-Steve West

Top notch pools and top notch company!! I now own two Thursday Pools and am looking forward to doing another one next year! You can’t go wrong with this company! Highly recommend it! -Kevin Weaver

Great business, great quality pool. The employees and management are so courteous. -Johnny E. Hatchet

We toured the factory and it was fantastic. Super fine swimming pools. -Christopher Gates

Fiberglass Pools: Everything You Need To Know Before You Buy

What Are the Disadvantages of Fiberglass Pools?

Posted on October 29, 2021June 24, 2026 by krista

We’ve been in your shoes before. You’ve decided to take the plunge and are looking at inground pools, and now you have to narrow down which type of inground swimming pool is best for you. You may have already compared vinyl vs fiberglass pools or the benefits of fiberglass over concrete pools and thought, “Wow, fiberglass sounds like a pretty solid choice!” But, now you want to know, “what are the disadvantages of fiberglass pools?” In this post, we’ll cover some potential downsides to aid in your pool decision journey.

Durability and Potential Damage

Let’s start with durability. How long do fiberglass swimming pools really last? You may have heard about typical repairs associated with certain inground pools—spider cracks, discoloration, etc.—and fiberglass pools, unfortunately, aren’t immune to these issues. For example, fiberglass pool gel coat problems can arise in the form of discoloration due to improper water chemistry and balance. That’s why we step up on our soapbox to stress the importance of pool maintenance. A fiberglass pool is one of the lowest maintenance inground pool types available, and proper care can ensure a significant decrease in your chances of damage. The life expectancy of a fiberglass pool can be a lifetime with proper upkeep. We’ve known some fiberglass pools to last 50 years!

Spider cracks in fiberglass pools can be the result of improper installation or manufacturing. Too much pressure on a spot in the pool, or a pool that’s built too thin, can lead to these surface cracks. This is why it’s important to go with a manufacturer that prioritizes both durability and flexibility with their fiberglass and an installer who knows their stuff when it comes to installation. Fiberglass pools have also been known to suffer from osmotic blistering. These little lumps form in the pool’s gel coat layer when water molecules are able to pass through. However, some fiberglass pool manufacturers offer surface warranties against osmotic blistering, which can put you at ease if this issue ever were to come up.

Limitations on Size and Shape

If your dream is to have a 70-foot long swimming pool, then you may be disappointed with fiberglass. Fiberglass pool shell manufacturers can typically only produce pools up to 40 feet in length and 16 feet in width due to shipping restrictions. The same can be said for custom shapes. A pool that’s in the exact shape of your dog isn’t going to happen with fiberglass since fiberglass pool shells are crafted from a pre-designed mold. Despite these limitations, there are many unique designs and features available, like zero entries and tanning ledges, that you may find in other types of pools but without the added comfort, safety (fiberglass pools aren’t as slippery when they include non-skid texture), and durability of fiberglass.

More Expensive Installation Than Some Other Pool Types

It’s true. Fiberglass isn’t the cheapest inground pool option on the market. And while how much a fiberglass pool costs, in the long run, depends on many factors, you could spend less upfront if you were to choose a vinyl liner pool. Installation could range anywhere from $25,000 to $65,000 for a vinyl pool. Other pool types may also be easier to install yourself, which can lower installation costs. We’ve all seen those “fiberglass pool installation gone wrong” videos online—this is why having a reputable installation professional is a must. Having an industry expert on your side ensures your project is done right and in a timely manner.

Speaking of costs, keep in mind that while fiberglass pools have higher upfront costs than other pool types, fiberglass pools tend to have lower maintenance costs over their lifetime, especially when you consider that they have manufacturers’ warranties.

We hope to have been helpful by discussing some potential disadvantages of fiberglass pools. If you haven’t already, be sure to check out our eBook that compares the three different types of inground pools side by side. If you’ve decided to take the plunge with fiberglass, then we have some resources to help you get started! Our inground fiberglass pool cost calculator can give you a ballpark estimate for your overall pool installation costs. The Idea Gallery has dozens of pictures of fiberglass pools to give you inspiration for pool colors, pool styles, landscaping, and more. If you’re wondering, “how can I find a fiberglass pool near me?” getting in touch with a pool dealer and getting an estimate would be a great next step.

Fiberglass Pool vs. Vinyl Pool: Which is Better For You?

Posted on September 9, 2021July 31, 2026 by krista

Quick Answer: Is a Fiberglass Pool or Vinyl Pool Better?

Fiberglass pools typically have a higher upfront cost than vinyl liner pools, but they also offer long-term advantages. They require less maintenance, can often be installed in just a few weeks, and never need a liner replacement. Vinyl liner pools generally cost less initially and provide greater flexibility in shape and design. However, liners can be susceptible to punctures and tears, requiring occasional repairs and eventual replacement every 5–10 years. If you’re looking for a pool with long-term durability and lower maintenance, fiberglass is often the better choice. If your priorities are minimizing upfront costs or creating a highly customized shape, a vinyl liner pool may be a better fit.

Comparing Fiberglass and Vinyl Pools Side by Side

An inground pool is a big purchase, one that changes your living space and your current routines. You’ll want to understand all of your options (meaning vinyl vs. fiberglass vs. concrete pools). And if you’re here, it means you’ve either narrowed your choices down to vinyl or fiberglass or are attempting to do so. Either way, you’ve come to the right place. In this post, we’ll compare fiberglass pools and vinyl pools side by side.

Pros and Cons: Fiberglass vs. Vinyl

	Fiberglass	Vinyl

How Fiberglass and Vinyl Pools Are Made and Installed

Both vinyl and fiberglass have relatively quick installation times, with vinyl about four to eight weeks and fiberglass about three weeks on average. An inground vinyl pool is 100% crafted on the job site, while fiberglass pool shells are manufactured at a designated facility using a mold. Being created from a mold means more quality control. Once the pool shell is made and delivered, it is placed into the pre-dug hole and leveled. Following this are various processes, including plumbing, electrical equipment, decking, and coping.

Vinyl pool installation takes place directly on the job site, starting with the wall panels, which are typically constructed with steel or plastic. The pool floor is then made with poured concrete, and this also serves as a base for the walls to connect. A blend of vermiculite, cement, and water, or a blend of sand, cement, and water, is used to create the pool bottom. The entire surface is then covered with the vinyl liner, and a vacuum is used to suction the liner into place. Plumbing, electrical equipment, decking, and coping follow suit.

How Much Each Pool Type Costs

Comparing vinyl pool cost to fiberglass pool cost is a fair comparison, as they both have lower upfront costs than a concrete pool might. According to our 2026 survey of independent Thursday Pools dealers, fiberglass pools typically range from $45,000 to $100,000 or more, while vinyl liner pools typically range from $25,000 to $65,000 or more. Fiberglass pricing will vary depending on many factors, so it’s always best to get a quote from an installation professional.

Pool Type	Typical Upfront Cost*	Ongoing Replacement Cost
Fiberglass	$45,000–$100,000+	None required
Vinyl liner	$25,000–$65,000+	$3,000–$7,500+ every 5–15 years

How Long Each Pool Type Lasts

The structure of a vinyl liner pool has the potential to last for decades, but the liner wears more quickly and is subject to tearing (especially if you have dogs who like to swim), so it will need to be replaced about every 5-10 years. Groundwater underneath the pool can cause other potential issues with the liner, such as floating. Customization is one of vinyl’s biggest selling points, but it comes at a cost: unique shapes are more expensive to build, more complicated to repair, and more likely to need liner work, all of which can chip away at the overall value.

When it comes to fiberglass, its rigid but flexible structure allows for maximum durability. Quality control in production is what makes the difference. Using a mold means fewer mistakes in the pool’s structure, and thick, even layers of gel coat make the pool more resistant to scratches and other surface damage over time. Innovations in fiberglass pool structures, such as the Backfill Eliminator™, help prevent groundwater accumulation and its associated issues. Maintenance and wear-and-tear repair end up costing you significantly less in the long run, and fiberglass pools can increase your home’s value.

Each Pool Type’s Safety

No matter which pool you choose, we will always shout from the rooftops: “Be careful! Accidents can happen!” Anyone entering or exiting a pool should practice caution. However, fiberglass does a great job of keeping swimmers of all shapes, sizes, and species safe as they enter and exit the pool. Non-skid texture applied to the fiberglass pool’s horizontal surfaces, along with its algae resistance, makes it less slippery and therefore safer. Features such as multiple entry and exit points, toe ledges, and swim-outs add both style and safety to a fiberglass pool and are great for kids (and pets!) who are learning to swim.

Vinyl pools provide a smooth surface for your feet that feels great, but smooth plus water can mean dangerous slips and falls. The potential tears we mentioned before can also pose safety risks for your pets, so you’ll want to keep an eye out.

Problems With Fiberglass Pools

Fiberglass fares well on durability, maintenance, and safety, but it falls short in two areas: custom design and upfront cost. As mentioned previously, fiberglass pools are manufactured based on a mold, meaning the design of that pool is set. Along with the obvious customization limits, like shape, placement, and features (steps or tanning ledges), fiberglass is also often limited in capacity. Fiberglass pools don’t get much wider than 16 feet and are generally less than 44 feet long (with some exceptions) due to transportation limitations, while pools built onsite can be much larger.

Problems With Vinyl Liner Pools

While vinyl pools have their perks, they also have their downside, particularly around durability and overall lifetime value. Vinyl liners need to be replaced fairly often (5-10 years on average with excellent pool care). Because a liner can be torn or punctured, these pools aren’t the best option if you’d like your pets to join you for a swim. It’s also worth considering whether you want a tanning ledge or lounge area, since these features are more difficult to incorporate into a vinyl pool design.

The right choice comes down to what you’re optimizing for: cost and customization, or durability and low upkeep. If you want a quick-to-install pool with boundless shape and size options and a lower upfront cost, a vinyl liner may be right for you. If you want a pool that’s lower maintenance, less likely to need repairs, quick to install, and comfortable and safe for you and your pets, fiberglass is calling your name.

Frequently Asked Questions

Is fiberglass or vinyl better for an inground pool?

It depends on what you’re prioritizing. Choose fiberglass if low maintenance and durability matter most; choose vinyl if minimizing upfront cost or getting a custom shape matters more.

How much does a fiberglass pool cost compared to a vinyl pool?

Fiberglass runs $45,000–$100,000+ and vinyl runs $25,000–$65,000+, based on a 2026 survey of independent Thursday Pools dealers. Actual pricing depends on size, features, region, and your local dealer.

Which lasts longer, a fiberglass pool or a vinyl liner pool?

A well-maintained fiberglass pool is designed to provide decades of enjoyment, with some pools lasting a lifetime of 50 years or more with proper care. A vinyl liner pool’s structure can also last many years, but the liner itself typically needs replacing every 5-10 years.

Is a fiberglass pool faster to install than a vinyl pool?

Yes. Fiberglass pools are typically installed in about three weeks on average because the shell arrives pre-manufactured, while vinyl pool installations usually take four to eight weeks since the pool is built entirely on-site.
