Big spas like the J-365 from Jacuzzi, with seating for 6-7 adults, can be the place for a party as well as one of the best big spas for experiencing a solo hydrotherapy massage. The J-365 is expertly designed with 44 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, while in another seat, 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.
