The Salina® is a seven-person open-seat hot tub from the Paradise® Series, the mid-tier hydrotherapy line manufactured by Caldera Spas, a Watkins Wellness brand. Measuring 7'5" square and holding 420 gallons of water, the Salina seats seven adults in an open layout with no lounger, distributing 40 jets across four configurations and shipping with a salt-water-ready FreshWater® IQ-ready sanitization system. It is the largest Paradise model by water volume and footprint, an open-seat spa for seven with a spacious footwell optimized for the high-performance Euphoria® jet. The Salina is sold and serviced through Seven Seas Pools & Spas.
7 adults (open-seat configuration, no lounger)
7'5" × 7'5" × 36" tall (226 × 226 × 91 cm)
40 total across 4 configurations
2 ReliaFlo® (1 dual-speed 2.5 HP, 1 single-speed 2.5 HP, 5.2 BHP each) plus an EnergyPro® circulation pump
The Salina fits households where the spa is a true social centerpiece, multi-generational families, regular hosts, or households that prioritize seat count and water volume over a reclined lounger. With seven seats in a 7'5" × 7'5" footprint and 420 gallons of water (the largest in the Paradise lineup), it gives every person room to spread out. A Caldera customer testimonial reads: "This is one of the best purchases I have made! It took me a moment to finally make the choice, but I am so thankful I did!", and another describes it as "Super relaxing and even better after a long day of yardwork."

The Salina is designed around Hot Tub Circuit Therapy®, Caldera's term for moving seat-to-seat across a planned sequence so each muscle group gets a dedicated treatment. On the Salina, the circuit runs through four stations targeting the neck, back, calves, thighs, and feet. Without a reclined lounger, the experience emphasizes upright social soaking, every seat puts you face-to-face with the rest of the group while still delivering targeted massage.
A typical circuit starts in the EcstaSeat® for large-muscle back work and calf jets, moves to the LumbarSsage® Seat for lower-back tension plus foot jet support, settles into the Angled Calf Jet seats for lower-leg work, and finishes in the spacious footwell with the Euphoria® jet delivering deep pressure to thighs, knees, calves, and feet. The Foot Ridge® anchors you in place so you can lean into the high-pressure Euphoria® jet without drifting. Two ReliaFlo® 2.5 HP pumps at 5.2 BHP each supply the strongest pump pairing in the Paradise lineup, which translates to firm jet feel even at full seven-person occupancy.

With FreshWater® IQ Ready, week-to-week maintenance reduces to monitoring smart alerts in the Caldera Spas App and replacing the salt cartridge when prompted. Filter cleaning runs on the standard monthly cadence for a 75 sq. ft. cartridge, see the filter care guide in the owners area.
For broader guidance, the salt-water hot tub care guide in the owners area covers cartridge replacement, ozone interaction (note: ozone is not compatible with FreshWater IQ), and seasonal draining intervals.
The Paradise Series is engineered for low operating cost via FiberCor® insulation, the EnergyPro® heater, and a continuous-run circulation pump. With 420 gallons (the largest Paradise water volume), expect heating and refill costs to run modestly higher than smaller Paradise models. The CEC certification means the Salina meets California's strict energy standards, which is a useful proxy for efficiency if you live elsewhere. Ask a Seven Seas advisor for an operating-cost estimate based on your climate and electricity rate.
No. The Salina is hardwired 230 V / 50 amp only. For 115 V plug-and-play hot tubs, see the Fantasy Series models.
