Which pool type is best?

Fiberglass for lowest lifetime maintenance, vinyl for lowest upfront cost, and gunite when you want a custom shape, depth or integrated spa.

$1,200 to $5,000 per year including chemicals, electricity, heating, water and service.

Does a pool add home value?

Typically 5% to 8% in warm-climate markets where pools are expected, and little to nothing in cold climates where they can even narrow your buyer pool.

Yes. Essentially every jurisdiction requires a barrier of a specified height with self-closing, self-latching gates, and insurers require it too.
