The Reunion® 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' × 7' and holding 350 gallons of water, the Reunion seats seven adults in an open layout with no lounger, distributing 38 jets across five configurations and shipping with a salt-water-ready FreshWater® IQ-ready sanitization system. The Reunion is the easy-maintenance open-seat spa for seven, designed to feel like a daily vacation. It is the social, group-soak option in the Paradise lineup, purpose-built for households that prioritize seat count over a reclined lounger position. The Reunion is sold and serviced through Seven Seas Pools & Spas.
7 adults (open-seat configuration, no lounger)
7' × 7' × 36" tall (213 × 213 × 91 cm)
38 total across 5 configurations
1 ReliaFlo® Single-Speed 2.5 HP plus 1 ReliaFlo® Dual-Speed 2.5 HP and an EnergyPro® circulation pump
The Reunion fits households where the spa is a social hub, large families, multi-generational households, regular hosts, or if you want every guest to have their own seat. With seven adult seats in an open layout, it gives the highest seat-count Paradise footprint at the smaller 7' × 7' size (vs. the 7'5" × 7'5" Salina), the right tub for households that gather around water regularly.

The Reunion 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 Reunion, the circuit runs through five 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 UltraMassage® Seat for neck, shoulders, middle back, calf, and foot work, moves to the EcstaSeat® for large-muscle back jets plus calf and foot coverage, settles into the LumbarSsage® Seat for lower-back tension, and finishes at the Euphoria® jet seat delivering deep pressure to thighs, knees, calves, and feet. The Foot Ridge® anchors you in place so you can lean into higher-pressure jets without drifting. Two ReliaFlo® 2.5 HP pumps deliver strong jet feel across the 38-jet array.

Level reinforced concrete pad, deck capable of supporting 5,085 lbs filled, or a prepared spa pad

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.
Yes, open-seat configuration means everyone has a spot with personalized jet coverage, plus one or two seats free for guests. For a household that uses fewer seats and wants a lounger, the Makena® (6 + lounger) is a strong alternative. For a true seven-person spa with a slightly larger footprint, see the Salina®.
The Paradise Series is engineered for low operating cost via FiberCor® insulation, the EnergyPro® heater, and a continuous-run circulation pump. Actual monthly electrical cost depends on local utility rates, ambient temperature, and use frequency. The CEC certification means the Reunion 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.
