What Are the Main Problems with Fiberglass Pools?

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:

1. It helps dispel common misperceptions of fiberglass pools.
2. It clarifies the type of care and quality you should expect from manufacturers and installers.
3. 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:

1. A fiberglass pool is thin and flimsy and will crack easily. 
2. A fiberglass pool is prone to separating from its deck, bulging, or even popping out of the ground. 
3. 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The first perception is related to an outdated image of fiberglass pools.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.
