Example: with Pool type Fiberglass ($70/sq ft) · Pool length 32 ft · Pool width 16 ft · Your region i United States (average) → Estimated cost: $48,384.
- Low estimate$41,126
- High estimate$60,480
- Cost per sq ft$95/sq ft

Pool type is the biggest lever: vinyl-liner pools are cheapest up front (the liner is replaced every 5\u201310 years), fiberglass costs more but installs fast, and concrete/gunite is the priciest and most customizable. Size, finish, add-ons, and your local labor market move it further.
Average pool size & what gets built where
The most popular inground pools run 14×28 to 16×32 ft — about 400–500 sq ft of water surface and 13,000–20,000 gallons — with depths stepping from 3–4 ft in the shallow end to 5–6 ft at the deep end (this page defaults to 32 × 16 ft). Builders’ standard ladder of sizes: 10×20, 12×24, 14×28, 16×32, 18×36, 20×40. Construction type skews regional: concrete/gunite dominates warm-climate markets (about 58% of Florida new builds, vs 32% fiberglass and 10% vinyl), while vinyl-liner pools have their stronghold in the Northeast and Midwest, where shorter seasons favor their lower upfront cost.

How it’s calculated & sources
Cost = surface area (length × width) × per-sq-ft rate for the type × finish factor, plus add-ons. Estimates are then scaled by a regional construction-cost factor for your area (U.S. average = 1.00).
Cost ranges from 2025–26 national home-improvement data (HomeAdvisor, Angi, Fixr and industry guides); regional factors approximate RS Means-style city cost indices. National average inground pool \u2248 $55,000 \u2014 vinyl $25\u201365k, fiberglass $30\u201385k, concrete/gunite $50\u2013120k.

Frequently asked questions
Does this include decking and landscaping?
No \u2014 the rates cover the pool shell and installation. Patio/decking, fencing, and landscaping are separate.
Why is gunite so much more?
Concrete/gunite pools are formed and finished on site \u2014 labor-intensive and fully custom.
How does region change it?
We scale the estimate by a regional construction-cost factor, so a pool costs more in high-cost areas like the coasts and less in lower-cost regions.
