The fiberglass pool models of this collection have a built-in spa that allows you to relax and forget about all of your stress and challenges after a long working day. If you are also planning to have a friend over and want to jump into the built-in spa to heat yourself for the party, this collection is ideal for you. In case you are also not in the mood for swimming in the pool and just want to enjoy the warmth of the built-in spa during more chilly days, you may again step into this pool from its built-in spa entrance.
