The Biggest Problems With Fiberglass Pools (And What Most Pool Builders Will Not Tell You)

The Biggest Problems With Fiberglass Pools (And What Most Pool Builders Will Not Tell You)

Fiberglass pools have become one of the most popular pool options for homeowners in Kentucky, and for good reason. They install faster, require less maintenance, and offer long term durability. But like any major investment, they are not perfect.

If you are researching fiberglass pools, you deserve to know the full picture. Not just the benefits, but the potential problems as well. Most pool companies avoid this conversation because they are afraid it will scare people away. In reality, honest information does the opposite. It helps homeowners make confident decisions and prevents regret later.

In this article, we will walk through the most common problems with fiberglass pools, explain which concerns are real and which are exaggerated, and help you determine whether fiberglass is truly the right fit for your backyard.

Why It Is Important to Talk About Fiberglass Pool Problems

Every pool type has limitations. Vinyl pools have liners that wear out. Concrete pools take longer to build and require more maintenance. Fiberglass pools have their own set of challenges that should be understood upfront.

Most disappointed pool owners are not upset because they chose fiberglass. They are upset because no one explained the limitations ahead of time. When expectations and reality do not line up, frustration follows.

Our goal is to prevent that from happening.

Design and Size Limitations of Fiberglass Pools


One of the biggest differences between fiberglass pools and other pool types is that fiberglass pools are pre-manufactured shells.

This means:

  • You choose from existing shapes and sizes

  • Depths are limited compared to concrete pools

  • Custom curves or extreme depths are not possible

For many families, this is not a problem at all. Most fiberglass pool designs include built in benches, tanning ledges, and family friendly layouts that work extremely well.

However, if you are looking for a completely custom shape, a diving pool, or a very deep end, fiberglass may not meet your expectations.

This is not a flaw. It is simply a design limitation that should be understood before moving forward.

Installation Matters More Than the Pool Itself

This is the most important section of this entire article.

Most fiberglass pool problems do not come from the pool shell. They come from poor installation.

Common installation related issues include:

  • Improper base preparation

  • Inadequate water management

  • Poor backfilling techniques

  • Lack of experience with fiberglass specific requirements

A fiberglass pool must be set on a properly compacted base and installed with careful attention to groundwater conditions. In areas with clay soil or high water tables, additional planning is critical.

When installed correctly, fiberglass pools are extremely durable. When shortcuts are taken, problems can occur regardless of how good the shell itself may be.

This is why choosing an experienced installer is just as important as choosing the pool.

Yard Access and Property Limitations

Because fiberglass pools arrive as a single piece, they must be delivered and placed into the yard using heavy equipment. This can create challenges in some properties. 

Potential access issues include:

  • Narrow side yards

  • Fences or structures blocking access

  • Steep slopes

  • Overhead power lines

  • Limited crane placement options

If a pool company does not carefully evaluate access early in the process, unexpected costs or design changes can arise later.

A proper site evaluation should always happen before finalizing a fiberglass pool plan.

Repairs and Damage Concerns

Another common fear homeowners have is whether fiberglass pools crack or fail over time.

In reality, modern fiberglass pool shells are extremely strong and flexible. Cracking is rare when the pool is properly installed.

However, potential issues can include:

  • Surface scratches

  • Gel coat wear over many years

  • Settlement issues caused by soil movement

Most of these concerns are either cosmetic or related to installation rather than the shell itself. Compared to resurfacing a concrete pool or replacing a vinyl liner, fiberglass repairs are generally less frequent and less disruptive.

Fiberglass Pools Are Not Right for Everyone

Fiberglass pools are an excellent option for many homeowners, but they are not the right choice for every situation.

Fiberglass may not be the best fit if:

  • You want a fully custom shape or depth

  • Your property has extreme access limitations

  • You want the lowest upfront cost regardless of long term maintenance

  • You are planning a very large or deep pool design

And that is okay.

A good pool builder should help you determine the right solution rather than forcing one option to fit every situation.

When Fiberglass Pools Are a Great Choice

Fiberglass pools are often a great choice for homeowners who:

  • Want a faster installation timeline

  • Prefer lower maintenance

  • Value long term durability

  • Plan to stay in their home for many years

  • Want predictable ownership costs

For families who want to spend more time enjoying their pool and less time maintaining it, fiberglass is often one of the best options available.
