Pool Costs & Pricing

What an inground pool costs in 2026 by type, size, and feature — with a transparent cost breakdown.

Quick answer

Most inground pools cost $45,000 to $100,000 installed in the U.S. in 2026. A basic vinyl-liner build can start near $35,000, while a large gunite pool with a spa, heating, and wide decking can top $120,000.

What drives the price

A pool quote is not one number — it is four costs stacked together, which is why bids for the same backyard can differ by tens of thousands of dollars. Our calculator builds the estimate additively, so you can see each layer.

First is the shell: the pool structure itself, priced by construction type (vinyl, fiberglass, or gunite) and size. Second is sitework — excavation, soil, access, and slope. Third is the deck and surround. Fourth is optional features like heating, a spa, saltwater, automation, and fencing.

The shell sets the floor, but sitework and features are what move the total. A simple rectangle on flat, easy-to-reach ground sits near the bottom of every range; add rock, a tight lot, or a long feature list and the same pool climbs fast.

Cost by pool type

Vinyl-liner is the cheapest to build, roughly $35,000 to $65,000, but the liner is a wear item you replace every 7 to 12 years. Fiberglass runs about $45,000 to $85,000, installs fast, and is the lowest-maintenance option — though shell size is capped by what ships on a truck.

Gunite (sprayed concrete) is the most expensive at roughly $60,000 to $120,000+, and also the most customizable — any shape, depth, or built-in feature is on the table. It is the type most likely to carry a spa, tanning ledge, and premium deck.

Use the pool cost calculator to price your exact size, type, and feature list, then read the guides below to go deeper on any one decision.

What to know before you commit

Sitework is the wildcard. Rock, a high water table, a steep grade, or tight access can quietly add $5,000 to $20,000 or more that a thin bid may leave out — so compare what each quote actually covers, not just the headline price.

Decking and features are where budgets stretch. The deck alone often adds 15% to 30% of the total, and features such as a spa, heating, and automation can add $20,000 to $40,000 combined. Price each one deliberately rather than bundling it into a vague allowance.

Then budget for the running cost. Chemicals, water, and pump electricity add up every year, and heating adds more — check the maintenance and heating guides before you sign.

Frequently asked questions

How much does an inground pool cost in 2026?
Most inground pools land between $45,000 and $100,000 installed. A basic vinyl-liner build can start near $35,000, while a large gunite pool with a spa, heating, and wide decking can exceed $120,000. The final number depends on construction type, size, sitework, decking, and features.
What is the cheapest type of inground pool?
Vinyl-liner is the cheapest to build, roughly $35,000 to $65,000, though you replace the liner every 7 to 12 years. Fiberglass is mid-range and lowest-maintenance, and gunite is the most expensive but fully customizable.
Why do pool quotes vary so much?
Because a pool bundles four separate costs — shell, sitework, decking, and features — and each varies widely. Two bids can differ by tens of thousands of dollars based on soil conditions, deck material, and which features are included, so compare exactly what each quote covers.
What adds the most to a pool's price?
After the shell, the biggest add-ons are sitework surprises like rock or difficult access ($5,000–$20,000+), the deck (often 15–30% of the total), and features such as a spa, heating, and automation, which can add $20,000–$40,000 combined.
