Differences Between Fiberglass and Gunite Pools

Updated: Dec 1, 2022

Differences Between Fiberglass and Gunite Pools

Many homeowners are stuck between gunite and fiberglass pools when planning to install a swimming pool on their property. However, knowing the differences between gunite and fiberglass pools is crucial so homeowners can feel confident in their investments. So let’s discuss their differences and see which one is best for you.

Fiberglass Pools

Fiberglass pools are made of composite material through fine fibers and glass woven into a fabric. It is then hardened with a polyester resin to reinforce many polymer products to create a stronger foundation. It leaves behind a smoother, water-resistant gel finish for high durability.

Safety and Maintenance

Because fiberglass has a smooth, water-resistant surface, there is less chance of bacteria and algae accumulation. As a result, it requires fewer chemicals and less rigorous cleaning; you’ll only need to wipe it down occasionally.

However, fiberglass pools tend to weigh less than gunite pools, which results in them popping out of place if the surrounding water gets too high. Moreover, you cannot use a diving board with a fiberglass pool because these pools can’t be too deep.

Durability and Cost

What makes fiberglass pools so appealing is their ability to hold up over time. Due to their smooth, water-resistant gel finish, they won’t need resurfacing. Additionally, fiberglass pools come in smaller sizes and make less expensive investments for installation. As for installation, you can have a fiberglass pool an average of two weeks after construction begins.

Gunite Pools

Gunite consists of cement, sand, and water applied with a pressure hose to create a rigid, dense layer of concrete. It’s a strong and long-lasting material that can be any shape desired. Gunite pools feature a rebar framework sprayed over with a concrete mixture, providing an extremely durable hold, and they’re built to last.

Installation and Cost

The time spent digging, planning, and setting up the wireframing requires patience. Moreover, spraying the wireframing with gunite can take several weeks to complete, and installing a gunite pool is more expensive.

However, a significant difference between gunite and fiberglass pools is that it can take up to half a year to install a gunite pool. If you’re getting a gunite pool, it’s best to plan your pool installation well before the warmer months so it’s ready for use. Meanwhile, fiberglass pools can be installed in a matter of weeks.

Durability and Maintenance

Despite the considerable costs and time to install your gunite pool, it’s highly durable and can last for many years. However, getting your gunite pool resurfaced every seven years is crucial to it living past its life expectancy.

Moreover, maintenance is an entirely different aspect of owning a gunite pool. Gunite can have microscopic holes throughout the surface, creating pockets for bacteria and algae to grow. As such, pool owners must perform routine cleaning and brushing along the walls to keep bacteria from getting out of hand.
