How much does a fiberglass pool cost installed?

Nationally, published installed prices run about $45,000 to $100,000. Our bottom-up model for a 14×28 shell with basic equipment and a 600 square foot concrete deck is $55,000 to $119,000 in St. George, Utah. Spas, covers, heaters and fencing are extra.

Is fiberglass cheaper than gunite?

Usually, for a comparable size. Fiberglass saves on labor and finish work, but the shell itself is a large fixed cost and freight adds thousands. Gunite starts higher but has no size or shape ceiling.

How long does a fiberglass pool take to install?

Once the shell is on site, setting, plumbing and backfill typically take one to two weeks. Lead time for the shell, permits and deck work push the whole project to one to three months.

Do fiberglass pools work in hot, dry climates and cold winters?

Yes. Fiberglass handles freeze-thaw well when installed with proper backfill and water management, and the smooth surface suits hard desert water. Rocky soil can raise excavation cost in St. George and Las Vegas.

What is not included in these ranges?

A code-required barrier fence, heater, spa, automatic cover, landscaping and rock or caliche excavation are priced as separate lines in our estimator.

Fiberglass Pool Cost (2026)

A fiberglass pool is a one-piece shell made in a factory, trucked to your yard and set into an excavated hole with a crane. Because the shell is finished before it arrives, installation takes days instead of weeks, and the gelcoat surface is smooth and low-maintenance.

The trade-off is choice: shapes and sizes are fixed by the manufacturer's molds, most shells top out around 16 by 40 feet, and the yard needs crane access. Published installed prices nationally run about $45,000 to $100,000; our bottom-up model for a 14×28 shell in St. George lands at $55,000 to $119,000 with a basic deck.
