The Florence® is a six-person hot tub from the Utopia® Series, the premium hydrotherapy line manufactured by Caldera Spas, a Watkins Wellness brand. Measuring 7' square and holding 360 gallons of water, the Florence pairs an open-seating layout plus a cool-down bench with 46 jets across seven specialized configurations and a salt-water-ready FreshWater® IQ sanitization system. It sits among the more compact Utopia models, above the Ravello™ and below the Tahitian®, and is the choice for households that want six-person capacity without committing to a lounger or the larger 7'5" footprint of the Geneva® and Niagara®. The Florence is sold and serviced through Seven Seas Pools & Spas.
6 adults (open seating plus cool-down bench, no lounger)
7' × 7' × 36" tall (213 × 213 × 91 cm)
46 total across 7 configurations
2 ReliaFlo® (1 dual-speed 2.5 HP, 1 single-speed 2.5 HP) plus an EnergyPro® circulation pump
The Florence fits households that want six-person open seating in a compact 7' footprint. The cool-down bench lets one occupant step out of the deep water without leaving the spa, a useful feature during longer soaks or for guests who prefer shallower seating. The open layout means every seat is upright and accessible, and Hot Tub Circuit Therapy® turns moving seat-to-seat into a guided full-body massage covering neck, shoulders, wrists, back, hips, thighs, calves, and feet. The Florence fits if you want premium Utopia materials in the smallest 7' × 7' footprint that still seats six.

The Florence 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. A typical circuit starts in the Atlas® Neck Massage seat for above-water shoulder and neck work, drops into the EcstaSeat® for large back-muscle work plus hip, wrist, and angled calf jets, settles into the LumbarSsage® Seat for lower-back tension, moves into the UltraMassage® Seat for upper-back relaxation, and finishes with the Euphoria® jets delivering deep pressure to thighs, knees, calves, and feet.
The cool-down bench is the Florence's distinctive ergonomic touch, a shallower seating surface that lets occupants step out of the full-depth jet zone without leaving the spa. The UltraMasseuse® System isn't included on the Florence, jet control is manual via the Advent® touchscreen and seat-side diverters. If you want one-touch automated jet sequencing should compare the Cantabria®.

The Florence requires a 230 V / 50 amp circuit wired to a GFCI sub-panel, the sub-panel is included with the spa. Site requirements:
Level reinforced concrete pad, deck capable of supporting 4,925 lbs filled, or a prepared spa pad
24" minimum service clearance on at least one side for equipment access
Standard delivery to ground-level installations
The 7' square footprint is among the smaller Utopia models, often easier to fit through standard gates than the Cantabria® or Geneva®
Seven Seas offers full delivery and installation service including site assessment, electrical coordination with a licensed electrician, and post-fill water balancing.
With FreshWater® IQ, week-to-week maintenance reduces to monitoring the smart alerts in the Caldera Spas App and replacing the salt cartridge when prompted (typically every four months). Filter cleaning runs on the same monthly cadence as any 100 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 cool-down bench is a shallower seating surface that lets occupants partially exit the deep water without leaving the spa. It's useful during longer soaks, for taller guests who want a shallower position, or for kids and teens who prefer lower water depth.
No. The Florence is hardwired 230 V / 50 amp only. For 115 V plug-and-play hot tubs, see the Aspire® and other Fantasy Series models.
FreshWater® IQ is the standard sanitization system, salt-generated chlorine plus smart monitoring. Ozone is an optional Corona Discharge ozonator that adds supplemental sanitation. They are not compatible, choose one or the other at the time of purchase.
Yes, a WeatherPro™ 4" tapered, custom-fit cover with curved front skirt and hinge seal is included. UL-listed child-safety locks and ASTM compliance are standard. Cover lifters (ProLift® II/III/IV) are optional add-ons.
The Utopia Series is engineered for low operating cost via the FiberCor® insulation, EnergyPro® heater, and circulation pump system. Actual monthly electrical cost depends on local utility rates, ambient temperature, and use frequency. The CEC certification means the Florence meets California's strict energy standards. The 360-gallon water volume is among the smaller in the Utopia line, which means faster heat-up after fill and refill cycles. Ask a Seven Seas advisor for an operating-cost estimate based on your climate and electricity rate.
Standard Florence delivery from Seven Seas runs 4-8 weeks from order, depending on current Caldera Spas production lead times and the shell color you select. Expedited inventory in stock at Seven Seas locations can ship within a week.
Yes, with proper ventilation and drainage. Indoor installations require an electrician-approved 230 V / 50 amp feed, a moisture-resistant floor structure rated for 4,925 lbs, and active humidity ventilation. See the indoor installation guide for full requirements.
