Connecticut pool estimate

Inground Pool Cost in Connecticut (2026)

Start with a 400 sq ft pool in Connecticut, compare materials, then adjust the calculator to your project. The regional model factor is 125% of the national baseline for the area-and-depth portion of the shell price; it is not a measured local labor rate. Residential electricity is approximately 29¢/kWh in the EIA-based data through April 2026.

Not an all-in project quote. Decking, fencing, heating, covers and other add-ons are not selected. Permits, unusual site conditions, utility upgrades and yard restoration require separate confirmation with your contractor. The displayed range is a modeled ±15% band, not a statistical confidence interval or a survey of local bids.

Read the calculation methodology and pricing and energy source notes before comparing a contractor's scope with this estimate.
