Kauai® 3-Person Hot Tub

The Kauai® is a compact hot tub built for easy, comfortable soaking without sacrificing a satisfying massage experience. Seating three adults, it pairs an UltraMassage® lounge with an EcstaSeat® so you can stretch out, sit upright, and choose the style of comfort that fits the moment. With 31 jets, conversation-friendly seating, and a footprint that works well on smaller patios and backyard spaces, it suits buyers across Traverse City and the wider Northern Michigan area who want a refined spa that feels simple to enjoy every day.

Phillips Lifestyles supports that experience with showroom guidance, installation, maintenance, and service options from a family-owned Northern Michigan dealer serving the region since 1980. For households in East Jordan, Cadillac, and Prudenville, the Kauai brings together compact sizing, energy-conscious construction, and a soothing seat layout that makes it a strong fit for steady unwinding at home.

Features and comfort

The Kauai’s seating layout is built around both relaxation and conversation. The UltraMassage® lounge offers a stretched-out position for full-body comfort, while the EcstaSeat® adds a more concentrated jet layout for a direct massage feel. That combination gives the tub a versatile personality: it can serve as a quiet retreat after work or a social space for close-knit soaking with family or friends.

Its 31-jet system adds to that versatility with multiple massage points working across the body. The Foot Ridge® helps anchor you in place while the jets do their job, and SpaGlo® LED lighting adds a calm visual touch for evening use. For buyers who want a spa that feels luxurious but not oversized, the Kauai keeps the focus on comfort, easy seating, and efficient use of space.

The lounge and seat mix also helps the spa suit different routines. One person can fully recline in the UltraMassage® lounge, while another can enjoy a more upright soak in the EcstaSeat®. That flexibility is useful for couples, small families, or anyone who likes to alternate between deep relaxation and a more social soak. The result is a hot tub that feels practical without losing the indulgent feel buyers expect from a premium spa.

Dimensions and technical details

The Kauai measures 7' x 5'5" x 29.5" and seats 3 adults. It holds 230 gallons of water and weighs 740 pounds dry, or about 3,185 pounds when filled. Power comes from a 230V / 50 amp electrical requirement, with a GFCI sub-panel included. The spa uses an Advent® LCD Control System and an EnergyPro® Heater rated at 4,000 watts.

Additional details include a 50 sq. ft. filter, one ReliaFlo® pump plus one single-speed 2.0 HP pump, and optional Corona Discharge ozone. Cabinet color choices include Java, Ash, and Parchment, while shell options include Arctic White, White Pearl, Tuscan Sun, Midnight Canyon, and Desert. Those options make it easier to coordinate the spa with surrounding deck boards, patio finishes, and exterior color palettes.

The Kauai is part of the Caldera Spas Paradise series, and its design emphasis is clear: compact footprint, strong massage variety, and dependable everyday usability. For shoppers who want a three-person spa that feels substantial without demanding too much patio space, those details matter.

Water care, efficiency, and options

Routine ownership is made easier by the included FreshWater® IQ System, which supports ongoing spa care as part of the overall setup. Energy-conscious construction is another major benefit. The spa uses fully insulated FiberCor® material, an EnergyPro® circulation pump, and a WeatherPro™ 4-inch tapered custom-fit cover with hinge seal. Together, those elements are designed to work as a system to help retain heat and support efficient operation.

The technical package also includes a 4,000-watt EnergyPro® heater and a circulation pump that supports consistent water movement. For buyers comparing spas, that matters because the best everyday hot tub is not only comfortable in the moment; it should also be straightforward to maintain and practical to live with over time. The Kauai is built with that kind of balance in mind.

Optional upgrades add another layer of personalization. Smart spa technology, powered by the Connected Spa Kit, is available for buyers who want connected convenience. Optional entertainment choices include a wireless sound system or wireless TV, and optional step and cover lifter selections help tailor the setup to the surrounding space. Those details make the Kauai adaptable to a range of backyard layouts and preferences.

Phillips Lifestyles support

Along with product selection help, Phillips Lifestyles offers expert installation and maintenance services for hot tubs, swim spas, fireplaces, and entertainment tables. That includes site preparation through final setup, plus hot tub repairs, a spa maintenance program, and free in-home consultations. If you want help thinking through placement, clearances, or spa size selection, the team also provides design support through its Home Consultation service.

The showroom experience can be especially helpful for local buyers who want confidence before they buy. Phillips Lifestyles also offers a test soak service for hot tubs, giving shoppers a chance to experience a spa before making a commitment. Combined with its long-running presence and local showrooms, that makes the buying process more practical for customers who want both product selection and after-sale support from one source. You can also start with Get Information and Pricing or browse the broader hot tubs collection.

A local outing can make the shopping process feel even more grounded. After exploring options, many residents like to pair a showroom stop with time around Mitchell State Park or Young State Park, both familiar names in the broader area.
