J-365 Good Times in a Big Hot Tub

A big hot tub like the J-365, with seating for 6-7 adults, is the place to party with friends one day and take in a solo hydrotherapy massage the next. The J-365 is expertly designed with 32 PowerPro® jets, sculpted-for-comfort seating and pillow headrests. The PowerPro Therapy Seat reaches every part of your back from the neck down for a stress-reducing soreness-relieving massage. In another seat in this big hot tub, three MX jets deliver a different type of hydromassage experience. A deep footwell houses enough jets for everyone to indulge in a foot massage. With all of the choices in seating and therapy experiences, you’ll feel like this big hot tub was built for you alone.

Learn More. And, a 4-stage water filtration system keeps water clean and free of debris quickly using four stages: ProClear™ Filter, ProCatch™ Filter Bag, surface skimmer and a pleated filter.
