How Much Will It Cost to Build an Inground Pool in 2025?

Posted on September 19, 2024May 28, 2025 by hannacol

Are you planning on turning your backyard into your private paradise next year? With the rising popularity of outdoor living spaces, adding an inground pool is one of the most rewarding upgrades homeowners make. But before plunging in, you are likely wondering, “How much will it actually cost to build a pool in 2025?” Inground pool costs can vary widely depending on factors like design, materials, and location, making it essential to understand what you’re investing in. Whether you want to build a sleek modern staycation location or a luxurious resort-style retreat, understanding the cost factors can help you plan more effectively.

2024 Inground Pool Cost Summary

Before discussing next year’s potential pool prices, let’s start with today’s market. As a baseline, here are the average costs of inground pools as of 2024:

Fiberglass Pools: Average between $30,000 and $85,000
Vinyl Liner Pools: Average between $25,000 and $65,000
Gunite (Concrete) Pools: Average between $50,000 and $120,000

These prices include the installation but do not account for additional features, landscaping, or ongoing maintenance costs.

What Other Key Factors Affect Pool Costs?

Beyond the basic pool types, universal factors will influence the cost of all 2025 pool installations. The following five are among the most significant and impactful.

Excavation Costs: The cost of excavating your yard varies depending on factors such as soil type, digging depth, terrain complexity, and obstructions. Average excavation costs range from $2.50 to $15.00 per cubic yard. Softer soils like sand are the least expensive to excavate, while more challenging conditions, such as rocky soil or bedrock, can cost $50 to over $200 per cubic yard.
Pool Safety: Your insurance company, state government, or local agencies may require pool fencing. Fencing costs average around $15 to $25 per linear foot.
Patio & Decking: Some decking around your pool perimeter may be included in your pool quote, but you may want to extend your living space beyond it. Basic concrete decks may cost $5 to $15 per square foot, while higher-end materials, such as paver patios, can range between $8 to $50 per square foot.
Pool Equipment & Features: Pool heaters, automatic covers, underwater lighting, and other features are optional, but they can provide priceless comfort and safety. A pool heater with installation ranges from $1,500 to $6,000 for gas, propane, electric resistance, and heat pumps. Solar pool heaters cost between $2,500 and $6,500. An automatic pool cover costs $8,000 to $20,000 installed and $1,000 to $3,600 for a manual cover. Inground pool lights cost $700 to $1,800.

Factors Affecting Pool Prices in 2025

While we wish we had a crystal ball, we can’t predict pool prices with certainty. However, we can look at a few factors that may affect the market in 2025. The following predictions are based on the most recent U.S. economic forecast from Deloitte Global Economics Research Center.

Inflation and Interest Rates: The forecast suggests that inflation will continue to be a concern. However, it is expected to moderate slightly as the Federal Reserve cuts interest rates gradually throughout 2024 and into 2025. Nevertheless, rates will still be higher than pre-pandemic levels, so financing pool construction could remain expensive. High borrowing costs will add to overall project expenses, particularly if you plan to finance your pool.
Labor Market Pressures: Although job growth is expected to slow in 2025, the labor market remains relatively tight, which could keep wages elevated. Higher wages for skilled construction workers will likely continue to drive up labor costs associated with pool installations. This factor contributes to the overall increase in pool prices, especially for labor-intensive types like gunite pools.
Consumer Spending and Confidence: Consumer spending is expected to slow as excess savings built up during the pandemic deplete and inflation affects disposable income. However, spending on home improvements, such as pools, may still see interest as homeowners focus on enhancing their living spaces. Continued demand could increase prices as contractors manage backlogs and prioritize high-paying projects.

All considered, a price increase for all pool types is possible. One key takeaway is that the more labor-intensive the installation, the more likely prices will increase. Fiberglass pools are the least labor-intensive because they are pre-manufactured off-site and delivered as a single unit. The installation process is much quicker, often taking just a few days to a couple of weeks, with minimal on-site work required beyond excavation and setting the pool into place.

Money Saving Tips for Pool Buyers in 2025

Prioritize Features: Focus on essential features first and consider adding non-essential upgrades later. This approach helps manage costs while still achieving your desired pool experience.
Consider Financing Options: If high interest rates persist, explore all financing options, including home equity loans or pool-specific financing, to find the best terms.
Invest in Energy-Efficient Equipment: Choose energy-efficient options such as variable-speed pumps, LED lighting, and solar heaters. These reduce long-term operating costs and make your pool more eco-friendly, providing ongoing savings on energy bills.
Keep Maintenance Costs Low: Regular maintenance can prevent costly repairs in the future. Investing in a pool cover can help reduce evaporation and keep debris out, saving on water and chemical costs. Efficiently managing your pool’s water levels and chemical balance also helps maintain the pool’s condition while keeping costs manageable.

Building a pool will always be a significant investment, and the type of inground pool you choose in 2025 can significantly impact upfront and long-term costs. Working with a reputable pool dealer and builder who understands your vision and can advise on cost-saving ideas is crucial no matter when or which option you choose.

Everything You Need To Know About Fiberglass Pool Installation

What is LSI?

Posted on April 9, 2024May 28, 2025 by kristin

What is LSI?

When it comes to maintaining the sparkling allure of your fiberglass pool, understanding the nuances and importance of pool water chemistry is paramount. Among the various metrics and tests available, the Langelier Saturation Index (LSI) is a critical yet often overlooked aspect of pool care. This post aims to demystify LSI and explain its importance in keeping your fiberglass pool in top condition for years to come.

What is the Langelier Saturation Index (LSI)?

Developed in the 1930s by Dr. Wilfred Langelier, the Langelier Saturation Index offers a precise, unbiased measure of your pool water’s balance. Ultimately, LSI assesses how saturated water is with calcium carbonate, a component crucial for maintaining the integrity and appearance of your pool. The index provides a clear, numeric value that reflects your water’s balance, with perfectly balanced, neutral water having a zero LSI value.

Maintaining your pool water within a range of -0.3 to +0.3 on the scale is acceptable, as it prevents the water from damaging the fiberglass surface. For saltwater pools, a slightly tighter range of -0.2 to +0.2 is recommended to account for the unique chemistry of saltwater systems.

Why is LSI Important for Your Fiberglass Pool?

Understanding and managing the LSI of your pool water is critical for several reasons:

Preventing Scale Formation: If the LSI is too high, it indicates your water is overly saturated with calcium carbonate. This condition leads to scale formation, as the water attempts to return to a balanced state by depositing excess minerals onto your pool’s surfaces and equipment. Not only does this affect the aesthetic appeal of your pool, but it can also hinder the efficiency of your pool’s filtration system.

Avoiding Corrosion and Damage: On the flip side, a low Langelier Saturation Index value indicates corrosive water that can pose a significant threat to the integrity of your fiberglass pool. Corrosive water can lead to chalking, a form of damage where the fiberglass gel coat surface begins to deteriorate. This damage not only affects the pool’s appearance but can also compromise its surface integrity over time.

Holistic Water Balance Approach: While keeping individual chemical levels within recommended ranges is essential, focusing solely on ranges and levels doesn’t provide a complete picture of your pool’s health. The Langelier Saturation Index offers an unbiased, comprehensive, and holistic view of your pool’s chemistry and water balance. By maintaining a balanced LSI, you ensure the longevity and durability of your fiberglass pool, protecting your investment and ensuring it remains a source of joy and relaxation for years to come.

How to Balance Your Pool Water Using LSI

Balancing your pool water’s LSI involves monitoring and adjusting several factors, including pH, total alkalinity, calcium hardness, temperature, and total dissolved solids. Here are some tips to help you maintain an optimal LSI:

Regular Testing: Use reliable test kits to frequently check the key factors affecting LSI levels. This process will help you identify any imbalances early on so you can take corrective action.

Adjust Chemical Levels: Based on your test results, adjust the levels of pH, alkalinity, and calcium hardness as needed to bring your pool water within the ideal LSI range.

Consider Pool Temperature: Remember that water temperature affects LSI, with warmer water tending to be more scale-forming. Adjust your maintenance routine seasonally to account for temperature changes.

Professional Consultation: If you’re unsure about adjusting your pool’s chemistry, don’t hesitate to seek professional advice. A pool maintenance expert can provide tailored recommendations based on your pool’s specific conditions.

Check out this article for a step-by-step approach to using Orenda’s helpful LSI calculator app to balance your pool water.

The Langelier Saturation Index is more than just a number; it’s a comprehensive guide to maintaining the beauty and integrity of your fiberglass pool. By understanding and managing your pool’s LSI, you’re not just caring for the water. You’re preserving the entire pool experience, ensuring it remains a safe, enjoyable, and beautiful oasis for many years. As part of your broader fiberglass pool maintenance strategy, mastering LSI empowers you to take proactive steps towards pristine water quality and pool longevity.

How Much is the Smallest Fiberglass Pool?

About Small Fiberglass Pools

Many fiberglass pools are over 600 square feet (e.g., more than 37.5 feet long by 16 feet wide). Comparatively speaking, a small fiberglass pool may be under 400 square feet. This size will fit into many smaller yards, take up less space, and is still fun and functional. To give you an idea of what that looks like, here are some Thursday Pools small fiberglass pool designs and their dimensions:

Small Fiberglass Pool Prices

Our general suggestion for getting a rough ballpark estimate for our fiberglass pools is to multiply your linear square feet by $1500. Of course, it’s more complicated than that, and you would need to get an estimate from a pool dealer near you to get firm numbers. Every case is different, and fiberglass pool prices vary according to a number of factors, including:

Are Small Pools Cheaper?

Yes. Generally speaking, small pools are less costly than larger pools. Not only do they save space in your backyard, but they also cost less to build initially due to fewer building materials being used and easier installation. Additionally, they cost less to maintain. A smaller pool requires less water and fewer chemicals and is generally easier to maintain than a larger pool.

Are Fiberglass Pools More Expensive?

Fiberglass pools are inground pools that are more expensive than above-ground pools. They are typically more expensive than a vinyl liner pool, but according to Home Guide, a fiberglass pool is generally 10 to 20 percent cheaper than a gunite pool. Additionally, fiberglass pools cost less to maintain than traditional pools. Over the course of 10 years, a fiberglass pool will save you 75 percent on maintenance costs as opposed to a concrete pool.

How Much Does a Fiberglass Pool Cost?

Fiberglass pools range from $45,000 to $85,000 on average, but smaller pools may run less. Use the Thursday Pools Pool Cost Calculator to get an estimate for your pool project based on size and desired options. This tool can help you better understand the cost breakdown behind your pool.

Wanting a Pool in Your Small Yard?

Posted on April 26, 2022August 26, 2025 by krista

No matter the size of your yard, creating a staycation-worthy backyard is within reach. Small fiberglass pools fit compact spaces without sacrificing style, comfort, or function. They offer a low-maintenance, budget-friendly solution with options like plunge pools and other ultra-compact designs, making it easier than ever to add a beautiful, refreshing pool to even the smallest backyard.

Is a Small Pool Worth It?

Absolutely! Small pools offer a smart, stylish solution for homeowners who want all the benefits of a pool without overwhelming their outdoor space.

With a compact design, you’ll have more room for other backyard features—like a lounge area, firepit, or outdoor kitchen—so you can truly enjoy a well-rounded outdoor living space. Smaller pools also mean easier upkeep, lower chemical use, and reduced energy costs, making maintenance a breeze.

And when it comes to your budget, going smaller can free up funds for extras like built-in seating, a tanning ledge, or an automatic pool cover. Best of all, small fiberglass pools come in a variety of layouts to suit how you plan to use your space—whether that’s relaxing, exercising, or entertaining a few close friends.

What Are Some Small Pool Options?

Before exploring specific designs, it’s important to understand the three main types of inground pools. Each offers unique benefits, and the best choice depends on your space, budget, timeline, and how involved you want to be with long-term upkeep.

Concrete (Gunite) Pools

Install Time: Approximately 3 to 6 months
Maintenance: Around 4 to 5 hours per week
Cost: $50,000 to $120,000+
Customization: Fully customizable in shape, size, and features

Concrete pools are known for their design flexibility and durability. If you have a very specific vision for your pool’s shape or want to maximize every inch of your yard, concrete offers the freedom to create a one-of-a-kind layout. Keep in mind, though, they take the longest to install and tend to require more hands-on maintenance and chemical use over time.

Vinyl Liner Pools

Install Time: Approximately 4 to 8 weeks
Maintenance: About 2 to 3 hours per week
Cost: $25,000 to $65,000
Customization: Custom sizes and shapes available

Vinyl liner pools are more affordable upfront, and builders can tailor them to fit many different backyard configurations. They’re a practical option if you want some customization without the higher price tag of concrete. However, the vinyl liner will eventually need replacement, which adds to long-term upkeep and costs.

Fiberglass Pools

Install Time: About 3 weeks
Maintenance: Around 1 hour per week—or less
Cost: $30,000 to $85,000
Customization: Limited to pre-designed shapes and sizes

Fiberglass pools come pre-formed from factory molds, which speeds up installation and simplifies maintenance. While you won’t have as much design flexibility, many models are available in compact sizes with built-in seating, tanning ledges, and other features that make the most of smaller spaces. The smooth, non-porous surface also resists algae growth, meaning fewer chemicals and less time cleaning.

Each pool type brings something different to the table—whether it’s complete customization, affordability, or ease of care. If you’re working with a smaller yard, all three can be viable options depending on your goals and preferences. Talking with a pool professional can help you weigh the trade-offs and find the best fit for your backyard.

Small Backyard Pool Ideas

Whether you’re looking for a true plunge pool or just a space-saving pool design, there are plenty of options for full-size enjoyment in smaller spaces. Below are some of Thursday Pools’ most popular compact models, each offering unique features to fit your lifestyle and yard size.

Petite and purposeful, The Nest is a compact plunge pool for relaxing, cooling off, and casual soaking. It features a flat bottom, wide entry steps, and is auto-cover ready—making it a stylish solution for tight spaces.

Other Compact Pool Options

These pools aren’t plunge-style, but still work well in smaller yards. They offer more swimming space and family-friendly layouts, often with added seating or space for games.

Lil Bob

Size: 13.5′ x 27.5′ | Depth: 4′6″

Lil Bob is all about flexibility. With wrap-around bench seating and a flat, even depth, it’s great for light swimming, games like water volleyball, or simply lounging with friends. It’s a compact design with room to move.

Titus

Sizes:

12′ x 26′ | Depth: 5′5″
14′ x 33′ | Depth: 5′10″

Titus offers a larger swim area while still fitting in smaller backyards. Its rounded shape and built-in seating create a comfortable space for both activity and rest. It’s a good choice if you want a pool that supports swimming as well as relaxation.

Wading Pool

Sizes:

9′ x 9′ | Depth: 1′6″
11′9″ x 13′9″ | Depth: 1′6″

Great as a stand-alone feature or a pool add-on, the Wading Pool is ideal for small children, a quick dip, or cooling off without getting fully in. It offers shallow, safe fun in a small footprint.

Wet Deck

Size: 8’1” x 14′ | Depth: 1′

The Wet Deck is a shallow splash zone perfect for sunbathing or letting young children play. Use it alongside another pool or on its own as a refreshing, low-maintenance backyard water feature.

What’s the Cheapest Inground Pool Cost?

Posted on March 21, 2022June 16, 2025 by kristin

If spending more time with loved ones (or by yourself) outdoors is climbing on your “should-have” list, and you have the space for an inground pool, you may have started an online search. Being a conscientious consumer, you could have landed here searching for the cheapest inground pool or even the “cheapest inground pool near me.” While no inground pool is “cheap,” this post gives an honest comparison of costs for vinyl liner, gunite, and fiberglass pools. We know an inground pool is a significant investment, so we hope this post will help you make an informed decision about inground pool costs.

Vinyl Liner Inground Pool Costs

Vinyl liner pools are generally the cheapest inground pool type with regard to upfront costs; however, their costs can increase significantly based on several factors. A ballpark figure on the average price of an inground vinyl liner pool is around $25,000 to $65000. Some constraints with vinyl you’ll want to be aware of:

Unique freeform shapes can add to your upfront price, as well as vinyl replacement costs, as manufacturing a custom liner adds time and materials.
High-end features such as bench seating or wraparound steps can add to your cost and may lead to further maintenance needs due to vinyl’s tendency to attract algae and become slippery.
The lifetime ownership, including the annual maintenance cost will offset some initial cost savings.
As previously mentioned, vinyl liner pools can attract algae, so you must clean them more often to keep them at bay. Expect to spend (or pay someone to spend) around four to eight hours per week on vinyl liner pool maintenance.
You could estimate maintenance expenses around $11,000 to $17,000 over ten years, excluding liner replacement costs.
Vinyl liners usually need to be replaced about every seven years (or fewer if the pool hasn’t been properly maintained), costing about $3,000- $7,500 on average.

Gunite Inground Pool Costs

Gunite pools typically cost the most to install, and their prices are the most varied across the country, depending on your location. In some regions, they are the high-volume choice of installers, and installation costs can be competitive. You tend to see more gunite installations in sunbelt states that are not subject to the freeze/thaw cycle. The national average price of a gunite pool is between $50,000 and $120,000. Here are some of the cost factors for gunite:

Freeforms generally cost more than basic shapes, and depending on how complicated the design is, the complexity may add more cost to the bottom line.
Each build is custom. Gunite costs more as you add features and options.
The porosity of gunite attracts algae and mineral deposits. It requires significant time and money to keep it clean. Expect to spend (or pay someone to spend) around four to eight hours per week on gunite pool maintenance.
Gunite pools usually require an acid wash to remove algae and mold every three to five years, and due to multiple acid washes, they often require replastering about every ten years.
Based on the average costs of regular pool maintenance tasks and requirements (such as acid washing, general cleaning, replastering, electrical/chemical usage, etc.), concrete pool owners can expect to pay $27,000 to $40,000 over 10 years for maintenance.

Fiberglass Inground Pool Costs

Fiberglass pools will usually fall in the middle between vinyl and gunite on the initial installation cost. However, lifetime ownership and annual maintenance costs tend to be lower than vinyl and gunite. HomeGuide’s 2024 inground pool cost guide reports that the average fiberglass pool price is between $30,000 and $85,000. However, many pool builders in our network report that their customers choose packages closer to $70,000 and $135,000. Some considerations of fiberglass pools relative to cost include:

Regardless of shape, the pricing is relatively consistent at around $1,800 per linear foot, except for beach entry fiberglass pool designs which tend to cost about 15 percent more.
Built-in features such as wraparound steps and benches, tanning ledges, and swim-outs do not cost extra, but they must already be part of the design, as fiberglass pools are built from pre-existing molds.
Easy access is essential to keeping costs down because they are delivered in one piece and not built on-site.
They are resistant to algae and require the lowest maintenance compared to the other inground pool types, needing only about an hour or two per week, and their ten-year cost for maintenance is around $5,000-$15,000.

Factors Affecting Any Inground Pool Cost

Some factors drive up costs, no matter what pool type you choose.

What’s the cheapest inground pool shape? Pool size affects the price of fiberglass pools rather than shape. However, for gunite and vinyl liner pools, the more complex the shape, the higher the cost.
What’s the cheapest pool size? Generally speaking, small inground pool costs tend to be less than larger ones for installation and maintenance.
Site conditions factor into pricing. Clay, sand, rock, and groundwater can all pose problems when installing any pool. Average excavation costs range from $2.50 to $15.00 per cubic yard for easier soil conditions, but more challenging conditions can cost $50 to over $200 per cubic yard.
Insurance companies and states or local agencies may require pool fencing. Fencing costs average around $15 to $25 per linear foot.
Pool cover prices vary. An automatic pool cover costs $8,000 to $20,000 installed and $1,000 to $3,600 for a manual cover.
Extra features add to the price. Additional features such as heaters, bubblers, deck jets, cascades, LED lighting, slides, and diving boards will also add to the cost.

Cheapest Fiberglass Pool Designs

What Is A Plunge Pool?

Posted on December 22, 2021August 26, 2025 by krista

You have a smaller yard, but you want a fiberglass pool. So here you are, researching your options. “Plunge pool” is one term you may see floating around in your search endeavors, but what exactly is a plunge pool? Plunge pools (you may also find the term “cocktail pools”) are a style of small pools that have a depth still suitable for movement and activity. Plunge pools generally are not shallow, earning their name because they’re deep enough to take a plunge, even though they’re small. You can find these pools in gunite, vinyl liner, and even fiberglass!

Some other questions and topics you may be wondering about could include:

How deep is a plunge pool?
What is the point of a plunge pool?
Are plunge pools easy to maintain?
How much does a fiberglass plunge pool cost?
What is a typical plunge pool size?

Since fiberglass is our jam, we’ll address these topics within the world of the fiberglass plunge pool. So let’s get started!

HOW DEEP IS A PLUNGE POOL?

How deep should a plunge pool be? There’s really no one-size-fits-all answer. Generally, somewhere between 4 and 5 feet fits the bill. A cocktail pool may be closer to a 3-foot depth.

WHAT IS THE POINT OF A PLUNGE POOL?

You may be thinking, “I don’t want to ‘take a plunge.’ I just want to be able to swim!” And that is the beauty of the plunge pool—they are compact enough to fit almost any yard, but their depth still allows for fun and light exercise. They also make for a great aesthetic gem in your backyard space. Fiberglass plunge pools are also growing in popularity because of their lower maintenance.

PLUNGE POOL INSTALLATION

As with any manufactured inground pool installation, experienced pool dealers who know their stuff should be the ones handling your plunge pool installation. They’ll be most familiar with your local area’s geographic considerations, pool regulations, proper installation techniques, and more. Contacting a pool dealer in your area is the best way to figure out what a plunge pool installation looks like where you live.

HOW MUCH DOES A FIBERGLASS PLUNGE POOL COST?

Now that you’ve learned a lot about fiberglass plunge pools, maybe you’re thinking, “is a plunge pool worth it?”

Talking with a local pool dealer near you will be the best way to get an accurate estimate on a plunge pool project in your yard, but we can explore some ballpark estimates for now. Using our general fiberglass pool installation rule of thumb at $2,000 per foot of length, plunge pool costs may range from $35,000 to $50,000 or more, depending on other add-ons, surrounding features, or local conditions.
