What an Inground Pool Costs in Chattanooga: 2026
A reference document, not a sales page. Published market ranges, the site conditions that move them, and what each format costs to own over 15 years.
The three formats, side by side
| Format | Build time | Shape freedom | Recurring cost | Annual upkeep |
|---|---|---|---|---|
| Vinyl liner | Shortest of the three on site after the panels are set | Limited to the panel layouts the manufacturer makes | Liner replacement on a cycle | $1,000–$2,000 a year |
| Fiberglass | Fastest overall — the shell arrives finished | Fixed; you pick from molds | Lowest recurring of the three | $500–$1,500 a year |
| Gunite / concrete | Longest, 8 to 12 weeks in this market | No limit — the shell is drawn, not ordered | Resurfacing every 10 to 15 years | $2,000–$4,000 a year |
Every figure on this page is a published market range or a survey average. It is not our quote. What your lot does to these numbers is the subject of the cost-driver table below.
Tennessee fiberglass figures, 2026 dealer survey
A 2026 survey of 20 Tennessee dealers put turn-key fiberglass installs at $74,211 small, $93,421 medium and $113,158 large. Turn-key in that survey means the shell, the installation, and the surrounding work needed to use the pool — not a shell price with the rest quoted later.
That distinction matters when comparing bids. A shell-only number can look thousands cheaper than a turn-key number for the identical pool. Read what is included before comparing two figures side by side. More on the format is on the fiberglass pools page.
National reference points
National industry averages put an inground pool at about $66,000. By size: a small 12x24 runs $35,000 to $50,000; a medium 14x28 to 16x32 runs $50,000 to $75,000; a large 16x40 or bigger runs $75,000 to $120,000+.
On a per-square-foot basis, the range across formats is $80 to $250, and gunite specifically runs $100 to $280. Those are national numbers. The Chattanooga variance sits mostly in what the ground does — see below, and see the gunite page for how a shot-in-place shell prices out.
Cost drivers: what actually moves the number
Two identical pool designs on two lots a mile apart can differ by tens of thousands. These are the published figures for the conditions and additions that cause it.
| Driver | Typical effect |
|---|---|
| Excavation in rock | about $4,500, vs about $1,200 in sand and $1,294 in clay |
| Hoe-ram day when rock is hit | $3,500–$5,500, usually a day or two |
| Above-average slope needing extra grading | about $3,356 |
| Limited equipment access | about $4,300 |
| Poured concrete decking, ~1,200 sq ft | about $11,825 (~$9.85/sq ft) |
| Paver decking, ~1,200 sq ft | about $13,881 (~$11.57/sq ft) |
| Code-required barrier fence, 300 linear ft | about $8,538 |
| Heater | about $5,881 |
| Automation | about $5,906 |
| UV sanitation | about $2,694 |
| Automatic safety cover | about $19,769 |
| Waterfall | about $3,138 |
| Integrated spa | about $20,700 |
The barrier fence line is not optional spending. The 2018 ISPSC barrier rules adopted here dictate its height, spacing and gate hardware — see the permit and code guide.
What it costs to own each year
Annual ownership cost by format: fiberglass $500 to $1,500, vinyl $1,000 to $2,000, gunite $2,000 to $4,000. Those cover chemistry, power, and routine maintenance across a normal year.
Heating is separate. A heat pump runs roughly $50 to $100 a month and extends the season two to three months. Gas heating runs $300 to $500 a month. Over a decade that gap is larger than most equipment upgrades on the driver table above.
15-year total cost of ownership
Using only the recurring figures already on this page, and setting the build price aside so the comparison is like for like:
| Format | Annual upkeep | 15 years of upkeep | Plus, within 15 years |
|---|---|---|---|
| Fiberglass | $500–$1,500 | $7,500–$22,500 | Lowest recurring of the three |
| Vinyl liner | $1,000–$2,000 | $15,000–$30,000 | Liner replacement on a cycle |
| Gunite | $2,000–$4,000 | $30,000–$60,000 | One resurfacing, on the 10-to-15-year cycle |
Read that against the build price rather than instead of it. Fiberglass carries a higher entry cost than vinyl in the Tennessee survey figures but the lowest 15-year upkeep; gunite is the highest on both, and buys shape freedom nothing else offers.
Why Chattanooga quotes spread wider than the national range
Depth to rock here is mapped, and it varies by soil unit across a few miles. On the eastern side of the county, Apison soils reach weathered shale at 20 to 40 inches and Armuchee at 20 to 36. On the plateau, Ramsey reaches sandstone in under 20 inches. In valley bottoms it can be clay the whole way down.
Put the driver table against that map and the spread explains itself: rock excavation is about $4,500 against about $1,200 in sand, a hoe-ram day is $3,500 to $5,500, and a sloped lot adds about $3,356 in grading. Three of those on one job is a five-figure swing before anyone changes the design.
Which permit office and code edition applies is the other local variable — that is on the permits page. Again, plainly: these are published market ranges, not our quote.
