Price ranges by pool type
NerdWallet's pool cost article, updated August 26, 2025, gives these installed ranges for an in-ground pool and credits HomeAdvisor, HomeGuide and Angi.

| Vinyl liner | $20,000 to $40,000 | 10 years |
| Fiberglass | $20,000 to $85,000 | 25 years |

The same article gives an average of about $66,000, a range from $14,000 to $135,000 for materials alone according to Angi, and about $50 to $125 per square foot of pool surface.
A second national source
HomeGuide's inground pool cost guide, dated July 16, 2025, gives $25,000 to $100,000 as the usual total, a national average of $62,500, and $80 to $250 per square foot installed. By material it lists fiberglass at $45,000 to $100,000 and concrete at $50,000 to $120,000. It lists a building permit at $100 to $300 and says most contractors include permit fees in the total. The two sources do not match, which shows how wide national ranges are.
| Item (HomeGuide) | Range given |
|---|---|
| Excavation | $1,000 to $5,000 |
| Fence | $5,000 to $15,000 |
| Enclosure | $4,000 to $14,000 |
| Pool heater, installed | $1,600 to $5,200 |
| Lights | $700 to $1,800 |

Items the Naples permit asks for
Collier County's checklist asks for engineered structural detail, a site-specific pool design with TDH calculations, a stormwater plan on most one and two family lots, and a certified survey on some sites (see the permit guide). Those can be separate lines on a quote, so ask who pays for each.
Be careful with very low "Naples average" prices
A Homeyou page for Naples shows up in Google with an "average pool builders cost" of $7,266 to $10,167. That is far below every in-ground range above, and the page does not say which job it prices. Do not use it to judge a quote.
How to use these numbers
- Use the ranges only to spot a quote that looks far too low or far too high.
- Ask each builder for an itemized written quote that names the pool type, size, finish, deck, equipment and enclosure.
- Compare the same scope across at least three quotes.
Frequently asked questions
What is the average cost of an in-ground pool?
NerdWallet reports about $66,000 on average, and HomeGuide about $62,500. Both are national figures, not Florida ones.
What costs extra beyond the pool?
NerdWallet lists permits ($100 to $1,800), site prep ($500 to $3,000), a deck ($3,000 to $20,000), fencing ($1,500 to $10,000), a heater ($2,000 to $4,000) and a filter ($250 to $2,000). A screen enclosure is not on that list, so ask for it as a separate line.
