For some builders who have traditionally found the installation of swimming pools to be challenging in some backyards—whether due to space or the homeowner’s budget—swim spas have opened the door to just about anyone looking for a large conventional pool. Swim spas, in a sense, are mini-versions of swimming pools, which can be installed just about anywhere, and accommodate swimming in place against a swift current. Where retailers truly benefit is the fact they can also promote the advantage of relaxation—especially after a swim or workout—in one of the jetted hydrotherapy seats these spas also offer.
