What are the Pros and Cons of Fiberglass Pools?

Table of Contents

In the world of home improvement, one area that consistently attracts many homeowners is the addition of a pool. Among the different options available in the market, fiberglass pools have rapidly carved out a significant niche for themselves. This blog post will discuss the ins and outs of fiberglass pools, exploring their pros and cons to help you decide whether they are the right fit for your home.

Overview of Fiberglass Pools

Fiberglass pools are increasingly popular due to their myriad of advantages, including quick installation times, consistent quality, and a smooth finish. However, like any product, they are not without their potential drawbacks. In the following sections, we will provide an all-encompassing view of fiberglass pools, shedding light on their pros that makes them a compelling choice for homeowners, and their cons that might deter others.

The Pros of Fiberglass Pools

While no one pool type is the perfect fit for everyone, fiberglass pools offer several appealing advantages worth considering. Let’s discuss these pros in more detail.

Fast Installation of Fiberglass Pools

One of the defining benefits of fiberglass pools is the fast installation. Unlike concrete pools, which can take months to install, fiberglass pools can be fully installed within two to three weeks. This speed can transform your backyard into a summer oasis almost before you know it, minimizing the disruption to your home life.

Built in Controlled Environments

Fiberglass pools are created in factory-controlled environments. This setting ensures that everything from temperature to measurements are meticulously controlled, resulting in a consistent and high-quality product. This feature stands in stark contrast to other pool types, which are subject to environmental conditions during installation.

The Lifelong Warranty on Fiberglass Pools

Another advantage of fiberglass pools is the lifetime warranty that typically accompanies them. As long as you own the home, your pool’s structure is guaranteed by most manufacturers. This warranty can provide significant peace of mind, knowing that your investment is protected for as long as you need it.

Comfortable Feel and Variety of Fiberglass Pools

Fiberglass pools are renowned for their smooth surface, offering a comfortable experience compared to the often rough texture of concrete pools. Additionally, various shapes and sizes are available, ensuring a good fit for most backyards.

The Cons of Fiberglass Pools

Like any other product, fiberglass pools have their own set of drawbacks. Let’s examine these cons to provide a balanced understanding.

Limitations in Customization of Fiberglass Pools

One limitation of fiberglass pools is their premade shapes and sizes. As they are factory-made, custom or freeform designs are typically not available. If you’re dreaming of a unique pool shape or size, this factor may be a significant drawback.

Unraveling the Myth: Do Fiberglass Pools Float?

The concept of floating fiberglass pools is a topic often discussed on the internet. However, it’s essential to note that any pool, not just fiberglass, can float under specific conditions.

Addressing the Floating Pool Problem

It’s essential to understand that pool floating can occur with any pool type, not just fiberglass pools. Let’s delve into the root cause of this issue and how it can be prevented.

Causes of Floating Pools: Not Exclusive to Fiberglass Pools

Floating pools are often a result of improper backfilling or hydrostatic pressure imbalance. This phenomenon is not unique to fiberglass pools and can occur with concrete or liner pools if not correctly installed.

The Role of Backfilling Material in Pool Stability

Using the right backfill material is crucial for the stability of any pool. Builders who cut costs by backfilling with the soil they excavated can create a hydrostatic pressure problem, leading to pool instability.

How Hydrostatic Pressure Affects Fiberglass Pools

The risk of a pool floating increases if the hydrostatic pressure underneath the pool exceeds the weight of the pool. Proper installation and maintenance practices can prevent this issue.

Maintaining Water Levels in Fiberglass Pools

Keeping the water in your fiberglass pool year-round is crucial to its stability. The water’s weight helps balance the pool against the upward pressure of groundwater.

If the water level drops significantly, the weight distribution can shift, increasing the risk of hydrostatic pressure imbalance and, consequently, floating. Therefore, it’s essential to keep a consistent water level, only lowering it about a foot below the skimmer for maintenance or in preparation for the off-season.

Implementing Hydrostatic Pressure Relief for Fiberglass Pools

For extra safety measures, installing a hydrostatic pressure relief system can prevent floating pools even in challenging situations. Let’s explore this feature more.

Introduction to Hydrostatic Pressure Relief Valves

A hydrostatic pressure relief valve is a device installed during pool construction to help balance the pressure beneath and inside the pool, reducing the risk of pool floating due to hydrostatic pressure.

Installation Process and Use of Hydrostatic Pressure Relief Valves

During the pool’s installation, a hydrostatic pressure relief valve is put in place on a bed of clean gravel. A pool cover pump can be used to drain off water if needed, maintaining the balance of pressure and ensuring the longevity and safety of your fiberglass pool. This mechanism is an essential part of pool construction that further enhances the stability of fiberglass pools.

With the right practices and measures, fiberglass pools can offer a great blend of durability, affordability, and quick installation, making them a viable option for many homeowners. However, it’s crucial to understand the pros and cons thoroughly before making your final decision.


As we wrap up our discussion, it’s crucial to revisit the pros and cons of fiberglass pools to give you a holistic understanding of what they offer.

Pros of Fiberglass Pools:

  • Fast installation, typically completed within two to three weeks.
  • Built in controlled, temperature-regulated environments, ensuring quality and consistency.
  • Accompanied by a lifelong warranty, offering peace of mind for homeowners.
  • Has a smooth finish and comes in a wide variety of shapes and sizes.

Cons of Fiberglass Pools:

  • Limited customization options due to the pre-made nature of the pools.
  • Risk of floating under specific conditions, often tied to incorrect backfilling practices and hydrostatic pressure.

Final Thoughts on Fiberglass Pools: Are they right for you?

Fiberglass pools come with a unique set of benefits that make them an excellent option for many homeowners. Their quick installation time, superior construction quality, and smooth, comfortable feel are just a few of the reasons why they continue to grow in popularity. However, their limitations in terms of customization and the need for proper backfilling and hydrostatic pressure management can be potential downsides.

Ultimately, the choice depends on your specific needs, preferences, and circumstances.
