About Fiberglass Swimming Pools

Fiberglass swimming pools are durable in-ground pools that require less maintenance than concrete or vinyl pools. Fiberglass pools are made from molds and can be ordered in a variety of sizes to fit most backyards. Before you make a decision about buying a fiberglass pool, consider your budget, the size of your property and the effect that running a pool filter will have on your electricity bill.

Function

Fiberglass in-ground swimming pools provide a convenient recreation option in your own backyard. The pools come in small, medium and large sizes and can be bought with a spa option. Pools can be heated to extend the swimming season and can be installed with fiber optic lights for night swimming.

Features

Fiberglass pools are molded pools that are installed in your yard in one piece. These pools are often compared to big bathtubs because that is what they look like before being installed. Fiberglass is a strong, lightweight material that is constructed by weaving small glass threads into fabric and hardening the fabric with a special polyester resin. A weather-resistant gel is added to the resin for a smooth finish.
Because there are no pits in the pool's surface as there may be in concrete pools, fiberglass pools are more resistant to algae formation and maintain more stable pH levels. The smooth surface also reduces the need to run the pool filter as there is less resistance on the surface of the water.

Time Frame

Fiberglass pools can usually be installed in one to three days. The time frame varies depending on how long electrical work and excavation of the pool site takes. If rock is hit during the excavation, specialized equipment may be need to remove it, extending the duration of the excavation and possibly increasing the price. Electrical and plumbing inspections are required before you can begin using your new pool.

Considerations

A fiberglass pool costs more than concrete pools or pools with vinyl liners, but fiberglass pools are more durable and don't require periodic surface replastering or liner replacement. Unlike concrete pools, fiberglass pools can be installed even in cold weather. Both chlorine and saltwater filters can be used with fiberglass pools.
The smooth surface of the fiberglass pool means that you won't have to worry about scrapes or abrasions from contact with the sides or bottom of the pool. Fiberglass pools have a shock absorbing capability and can flex one to two feet. If you live in an earthquake area, buying a pool that can move without cracking is a wise investment.

Warning

It is not a good idea to drain your fiberglass pool. If you do, ground pressure from outside the pool could cause the pool to crack or buckle. If your pool must be drained for some reason, contact your pool installer for assistance.
Use non-abrasive cleaners to remove the ring that can form on the pool wall from suntan lotion and body oils. Brushes, abrasive cleaners, scrapers and steel wool can damage the pool's gel coat.
