As the smallest of the Paradise Series spas, the Kauai is a compact hot tub measuring 7′ x 5’5″ x 29.5″. It’s a popular choice among couples and small families that don’t require a larger spa. With 2 bench seats and one lounge seat, there’s lots to love about the Kauai. It has room for up to 3 people and features 31 jets powered by a robust pump. Jets include 24 Euro jets, 5 VersaSsage® jets, and 2 Euro-Pulse® jets.

The Kauai is FreshWater Salt System ready, like all spas in the Paradise Series lineup. This system uses a disposable titanium cartridge that creates chlorine from salt and then releases it into the water, keeping it clean and ready to use for up to an entire year, which translates into less work and worry, and more time enjoying your spa!

The uniquely designed Foot Ridge of the Kauai helps you stay anchored in place while the jets go to work, and you’ll also love the visual appeal of SpaGlo® 7 points-of-interior lights LED lighting to illuminate the night. The Kauai comes with the exclusive EcoTech cabinet that gives your spa a modern aesthetic that is also extremely durable. The cabinet comes in Java, Ash, or Parchment. Shell colors choices are Arctic White, White Pearl, Tuscan Sun, Midnight Canyon, or Desert. Every day will feel like a vacation with the Kauai!
