10 Facts About Fiberglass Pools That Every Pool Owner Should Know


Fiberglass pools have been steadily gaining popularity over the years. Since their introduction in the late 60s, these pools have disrupted the market by providing a “greener” alternative to traditional concrete pools. With lower maintenance requirements, quicker installation, and longer lifespan, fiberglass pools offer numerous benefits for pool owners. If you’re considering upgrading to a fiberglass pool or simply want to learn more about them, this article will provide you with the essential facts you need to know.

What is a fiberglass pool?

A fiberglass pool is a “one piece swimming pool” that is prebuilt in a factory from a mold and then shipped to the desired location. However, contrary to popular belief, fiberglass pools are not made entirely of fiberglass. The pool consists of multiple layers that provide strength and support, with a tough and flexible fiberglass shell as the main component. These pools come in various shapes, including rectangles, circles, and combination shapes with built-in seating and steps.

How much does a fiberglass pool cost?

The cost of fiberglass pools can vary. On average, the national cost for a fiberglass pool is around $40,000. The pricing includes two major factors: the pool shell and installation. The pool shell itself ranges from $10,000 to $40,000, depending on its size, build quality, and included features. Installation adds another $15,000 to $30,000 to the total price. The installation process involves several steps, such as excavating the ground, installing plumbing, securing the shell, and filling the pool. Thus, most fiberglass pools cost between $15,000 and $70,000.

How long do fiberglass pools last?

Fiberglass pools are known for their durability and longevity. They can last for more than 30 years with proper maintenance. Many fiberglass pools from the 60s are still in use today, showcasing their remarkable durability. While they don’t require replastering or relining, fiberglass pools do need a gel coating replacement every 15 years. However, this maintenance task is relatively inexpensive compared to the maintenance required by concrete and vinyl pools.

How much maintenance does a fiberglass pool need?

Fiberglass pools require the least maintenance compared to other types of swimming pools. You’ll find that maintaining a fiberglass pool requires less than half the work needed for concrete or vinyl pools. The reason behind this is the waterproof gel coating on the pool’s surface. This coating forms a non-porous layer, making it difficult for water or chemicals to get absorbed, which is a common issue with concrete and vinyl pools. The gel coating also acts as a shield against pool algae and micro debris, reducing the need for constant brushing, skimming, and chemical addition.

What are fiberglass pools made of?

how fiberglass pools are made

Fiberglass pools consist of six different layers that work together to form the pool shell. The most prominent layer is the gel coat surface layer, which provides a smooth and algae-resistant finish while protecting the layers underneath. Other layers include a vinyl ester resin layer for corrosion resistance and waterproofing, chopped fiberglass layers for added strength, a roving layer to reduce stress, and a structural comb layer for additional support at tension points. These layers combine to create a durable and damage-resistant pool shell.

How are fiberglass pools made?

Fiberglass pools are pre-made in a factory and then shipped to the desired location. Unlike concrete and vinyl pools, which are built on-site, fiberglass pools arrive ready for installation. The factory-built process allows manufacturers to produce pools more efficiently, providing a wide range of options for customers. Additionally, the pre-made nature of fiberglass pools significantly reduces their installation time.

How long do fiberglass pools take to install?

Fiberglass pools have the shortest installation time compared to other types of pools. While concrete pools can take 3-6 months to install, a fiberglass pool can be installed in just 3-6 weeks. Since these pools are pre-made and only require on-site installation, the process is much quicker and more efficient. Choosing a fiberglass pool means enjoying your pool sooner and spending less time waiting for construction to finish.

What type of swimming pool is the strongest?

Fiberglass pools are considered the most durable and damage-resistant type of swimming pool. Unlike concrete pools, which are prone to cracking over time, fiberglass pools are flexible and nearly immune to cracks. Any surface cracks that do appear can be easily repaired and typically only occur every 10 years. The non-porous gel coating of fiberglass pools also offers better protection against chemical and water damage.

Are fiberglass pools expensive to own?

fiberglass pool save energy and chemicals

While fiberglass pools may have a higher upfront cost compared to concrete pools, they are the least expensive to own in the long run. The low maintenance requirements of fiberglass pools save you money over time. Unlike concrete pools that may require replastering or vinyl pools that need replacement, fiberglass pools are more durable and require fewer repairs. Additionally, the non-porous surface of fiberglass pools prevents heat, chemicals, and water from escaping, resulting in lower electricity and chemical costs.

Closing thoughts on fiberglass pools

In summary, fiberglass pools offer numerous advantages for pool owners, including their long lifespan, affordability, low maintenance, resistance to algae and stains, quick installation, and increasing property value. Investing in a fiberglass pool provides a durable and enjoyable swimming experience for years to come.
