The Hydropool Self-Cleaning 570 is a 5 person hot tub that incorporates a never-float lounger, four full seats and easy-access, non-slip steps built right into the interior. This hot tub is one of Hydropool’s best selling spas, because while 95% of customers are buying a hot tub for two people, they often seek the capability of fitting four. With its spacious interior and multi-level seating, the Hydropool 570 is roomy enough to treat you and four friends like royalty, while its European styling makes it a beautiful addition to anyone’s castle.
