Expect to pay $50,000–$85,000 installed for a fiberglass inground pool in 2024.

That’s the number for a turnkey job: pool shell, delivery, excavation, plumbing, electrical, and a basic concrete deck. Throw in landscaping, a heater, or a salt system and you’re looking at $90,000 or more.

The wide range comes down to two things: where you live and how much dirt you need to move. A 12x24 pool in Florida with sandy soil costs less than the same pool in rocky New England. Local permits and labor rates swing prices by $10,000–$15,000 easily.

Fiberglass is usually the middle ground between vinyl liner and concrete. It installs faster (3–4 weeks vs. months for concrete) and holds up better over time, but you’re stuck with the factory shape and color. No custom designs.

If you’re serious, get three quotes from local installers. National averages are useless when the guy down the street charges different rates. And make sure the quote includes site prep, dirt removal, and the first year’s chemistry kit — some contractors nickel-and-dime you on that stuff.

Don’t forget ongoing costs: electricity for the pump, chemicals, and eventual liner replacement (every 10–12 years, ~$3,000–$5,000). The pool itself is the cheap part.
