Estimate the cost of an in-ground pool. Pick size, shell, equipment tier, deck, fence, and add-ons. 2026 data; not a contractor bid.

What this is: a planning-range pool calculator informed by Pentair / Hayward / Latham / Leisure / Trilogy manufacturer pricing, HomeGuide, HomeAdvisor, Homewyse, ISPSC code requirements, and licensed cost-estimating references.
Size scaling: shell, equipment, plumbing, excavation, decking, and fence all scale with length × width and depth inputs. Reference baseline is a 32x16 ft, 5.5 ft avg depth fiberglass install. Excavation also scales with access difficulty and rock encountered.
Labor is modeled from per-unit installed rates with a crew-rate sanity check ($75-$140/crew-hr loaded billing rate), informed by BLS OEWS 47-2061 (Construction Laborers).

| Configuration | Range | Timeline |
|---|---|---|
| Vinyl-liner 28x14, basic equipment, concrete deck | $45,000-$80,000 | 4-6 weeks |
| Fiberglass 32x16, smart equipment, paver deck | $65,000-$120,000 | 2-4 weeks |
| Gunite 40x20, freeform, premium equipment, pebble | $120,000-$220,000+ | 8-12 weeks |
| Lap pool 50x10, fiberglass, tight access | $80,000-$140,000 | 3-5 weeks |
| Add-on: rocky soil excavation | +$5,000-$15,000 | +1 week |
| Add-on: heater + saltwater system | +$5,000-$12,000 | included |
A 32x16 ft fiberglass pool with paver deck and heat-pump heater runs $65,000-$120,000 turnkey in 2026. Vinyl-liner equivalent: $50,000-$95,000. Gunite custom-shape 40x20: $90,000-$200,000+. Excavation access, soil/rock conditions, and deck/fence square footage all materially affect the final price.
Roughly linearly with surface area for shell, equipment, plumbing, deck, and excavation. Doubling from 32x16 (512 sf) to 40x20 (800 sf) lifts the total by 50-70%. Depth above the typical 5.5 ft adds excavation labor and pump capacity. Soil with rock can add 50%+ to excavation alone.
Vinyl-liner: cheapest upfront, liner replaced every 7-10 yr. Fiberglass: 2-4 week install, lowest maintenance, drop-in shell limits shape/size choices. Gunite/shotcrete: any custom shape, 50+ yr life, requires re-plastering every 10-15 yr — most expensive, longest install (2-3 months). Equipment tier (basic/smart/premium) often matters more than shell type.
Yes — IRC and ISPSC require a 4-ft minimum barrier (fence, wall, or pool cover) around any pool deeper than 24 inches. Self-closing/self-latching gates are mandatory. Coastal Florida (HVHZ) and California require additional safety devices. A typical 32x16 pool needs ~120 lf of fence; larger pools and irregular yards add 30-50%.
In-ground pools are pro-only. Above-ground vinyl pools are the realistic DIY path; the calculator's DIY mode reflects that.
