What your builder adds

Your pool builder handles the excavation, digging the hole for your fiberglass plunge pool, and then sets the shell with a crane. The builder adds the pump, filter and heater, so you can use it as a heated plunge pool. Plan coping around the edge and decking for your in-ground pool. Yard access needs a clear crane swing path.
