In 2026, the national average inground pool cost is around $66,000, with most U.S. homeowners spending between $44,500 and $87,500 for a complete build. The full range runs from roughly $25,000 for a basic vinyl-liner pool to $175,000 or more for a custom concrete design — and elaborate concrete projects can push past $200,000. Where your project lands depends on the construction type, size, depth, decking, features, and where you live.
That is a wide range, and it should be. Anyone who quotes you a single, precise number before seeing your yard is guessing. Below we break down what actually drives the price so you can build a realistic estimate for your own situation.
Inground pool cost at a glance
Here is how the numbers stack up for 2026. The biggest single factor is the construction type, so that is where most estimates start.
| Construction type | Typical installed cost | Build time | Best for |
|---|---|---|---|
| Vinyl liner | $25,000 - $65,000 | 3 - 6 weeks | Lowest upfront cost |
| Fiberglass | $35,000 - $120,000 | 1 - 3 weeks | Lowest maintenance |
| Concrete / gunite | $50,000 - $175,000+ | 3 - 6 months | Full customization |
For a deeper look at the trade-offs between these three, see our guide to pool types and their costs.
The biggest cost drivers
1. Construction type
Vinyl liner pools are the cheapest to install and go in fast, but the liner wears out and must be replaced every 7 to 10 years at $3,400 to $6,800 each time. Fiberglass pools arrive as a pre-made shell, install in just 1 to 3 weeks, and have the lowest ongoing maintenance — but shells wider than about 16 feet are hard to truck to your site, which limits your size and shape choices. Concrete (gunite) pools can be built in any shape or size and last for decades, but they take 3 to 6 months to build and carry the highest maintenance, including periodic acid washing and resurfacing.
2. Size
Cost scales with the water surface area, not just length. Our calculator uses a simple model that mirrors how builders price jobs: a fixed base cost plus a per-square-foot rate. For vinyl that is roughly $23,000 base + $58/sq ft; for fiberglass about $27,000 base + $92/sq ft; and for concrete around $30,000 base + $125/sq ft. The base covers excavation, plumbing, and equipment that you pay for no matter how small the pool, which is why a tiny pool is rarely cheap per square foot.
3. Shape
The four shapes most homeowners choose are rectangle, oval, kidney, and L-shape. Shape barely moves the needle on fiberglass because you are buying a catalog shell — but on custom concrete and, to a lesser degree, vinyl, a curvy or angled design adds labor and material cost compared to a plain rectangle.
4. Depth
Depth is an underrated cost lever. A shallow play pool (a flat floor around 3.5 to 4.5 feet) runs about 5% less than a standard pool because there is less to dig and less water to treat. A standard pool (3 feet sloping to roughly 5 to 6 feet, no diving) is the baseline. Adding a true 8-foot-plus deep end for diving adds about 20% to the build — and a diving board is considered an "attractive nuisance," which can raise your home insurance.
5. Decking
The patio around the pool is a major line item that is easy to overlook. Most homeowners do not know their deck square footage, so it helps to think of decking as a band of patio wrapping the pool: about 3 feet is a walkway, 5 feet gives you a walk plus room for a couple of loungers (the typical default), and 8 feet is a full patio and lounge zone. Material matters a lot here:
| Decking material | Installed cost per sq ft |
|---|---|
| Poured concrete slab (default) | $6 - $15 |
| Stamped concrete | $12 - $28 |
| Concrete pavers | $15 - $32 |
| Natural stone / travertine | $15 - $40 |
To estimate the area of a surrounding band of width w around a pool with perimeter P, use roughly P x w + 3.14 x w². Our dedicated pool deck cost guide walks through this with examples.
6. Region
Where you live changes the price meaningfully. Warm southern markets like Texas, Florida, Arizona, and Georgia are the cheapest, thanks to year-round building seasons and dense competition among builders. Colder northeastern markets cost the most. As a rough multiplier on the national baseline, our tool uses about 0.92 for the South, 1.0 for the Midwest, 1.05 for the West, and 1.15 for the Northeast.

The base build is only part of the story. Popular upgrades and site work can add anywhere from a few thousand to tens of thousands of dollars:
- Heater: about $5,200 installed (and roughly $650/year to run)
- Automation: $2,500 - $5,000 for basic; $8,000 - $20,000 for a full smart system
- Safety cover: $1,000 - $3,600 manual; $8,000 - $20,000 automatic
- Fencing: $10 - $45 per linear foot (often required by code)
- Tanning / sun ledge: $2,000 - $4,000
- Waterline tile: about $25 per linear foot
- Saltwater system: about $2,000
Then there are the site factors that surprise first-time buyers: excavation $1,000 - $5,000, permits $100 - $1,000+, and electrical hookup $2,000 - $10,000. The wildcard is your soil — tough or expansive clay can add $5,000 to $30,000 or more to handle properly. This is exactly why a good estimate is a range, not a fixed figure.
Don't forget yearly upkeep
The purchase price is one decision; living with the pool is another. Annual upkeep (chemicals, power, water) varies sharply by type:
- Fiberglass: about $950/year — the lowest, thanks to its non-porous surface
- Vinyl: about $1,400/year, plus liner replacement that averages out to about $625/year
- Concrete: about $2,400/year — higher chemical use, plus acid washing and resurfacing over time
Running a heater adds about $650/year, and a spa adds roughly $400/year. Over a decade, these differences can rival the gap in upfront price, so weigh them together.
A realistic example build
Say a homeowner in Georgia wants a 16 x 32-foot fiberglass pool (about 512 square feet of water) with a standard depth and a 5-foot concrete-paver deck. Here is how the math comes together:
- Base build: about $27,000 fixed + ($92 x 512 sq ft), which is roughly $27,000 + $47,000 = about $74,000 before regional adjustment
- Depth: standard, so no adder
- Region: the South multiplier of 0.92 brings the build to roughly $68,000
- Decking: a 5-foot paver band around a ~96-foot perimeter is roughly 480 + 79 = ~559 sq ft; at about $20/sq ft that is around $11,000
- A heater: about $5,200
That lands in the low-to-mid $80,000s all in — comfortably inside the typical $44,500 to $87,500 band. Swap in a smaller vinyl pool and you could be down near $40,000; go custom concrete with a deep end and stone decking and you could clear $120,000. Same yard, very different totals — which is the whole point of pricing yours specifically. To pressure-test the trade-offs, compare your options in our guide to pool types and their costs.
The bottom line
For 2026, budget around $66,000 for an average inground pool, and expect most realistic projects to fall between $44,500 and $87,500. Vinyl is the value play, fiberglass is the low-maintenance middle, and concrete is the premium, fully custom option. Nail down your type, size, depth, decking, and region, account for add-ons and site work, and you will have an honest range to take to builders.
