The Splendor® is a five-person, round hot tub from the Fantasy Series, the entry-tier hydrotherapy line manufactured by Caldera Spas, a Watkins Wellness brand. Measuring 6'6" in diameter and holding 265 gallons of water, the Splendor uses barrier-free seating around an open round well and a built-in diverter valve that toggles between personalized jet massage and a high-volume whirlpool feature. It runs on a standard 115V outlet (with optional 230V conversion), uses a rotomolded unibody cabinet, and ships FROG® Sanitizing System Ready. The barrier-free seating works equally well for a solo soak or for conversing with five of your closest friends. The Splendor is sold and serviced through Seven Seas Pools & Spas.
5 adults (barrier-free round seating)
6'6" diameter × 33" tall (1.98 m × 0.84 m)
21 total (18 Mini, 2 Twin Pulse, 1 Turbo)
2-speed 1.5 HP jet pump
The Splendor fits households who want a social, conversational soak rather than fixed-position hydrotherapy seats, friends gathering around a round well, families with kids, or owners who value the freedom to stretch and reposition without bumping into a fixed seat. The barrier-free round design and the diverter-valve whirlpool mode make it the most distinctive layout in the Fantasy lineup. The 115V plug-and-play install (with 230V conversion option) keeps electrical complexity off the table for most owners. One Fantasy Series owner sums up the appeal: "I love my round hot tub, that leaves freedom for stretching...Very good value for the price."

The Splendor uses a single 2-speed 1.5 HP jet pump driving 21 jets across three patterns. A built-in diverter valve lets owners route water flow between personalized seat-jet massage and a higher-volume whirlpool circuit driven by the central Turbo Jet.
| Jet Type | Count | Targeted Area |
|---|---|---|
| Mini Jets | 18 | Distributed back, shoulder, and side coverage around the round well |

The Splendor ships FROG® Sanitizing System Ready. Caldera's product copy describes the system this way: "Prefilled cartridges release sanitizing minerals and chlorine or bromine and self-regulate based on your spa's needs for soft, clean water."

The Splendor is the only round model in the Fantasy Series, and that shape changes the soak fundamentally. Instead of fixed seats with assigned jet patterns, the round well lets owners reposition freely, stretch out solo across the diameter, or sit five adults around the perimeter for a conversational soak. Flip the built-in diverter valve and the experience shifts from personalized seat-jet massage to a high-volume whirlpool mode, with the central Turbo Jet driving water circulation across the entire tub. The 18 Mini Jets distribute the bulk of the personal massage, the 2 Twin Pulse Jets add pulsing pressure at primary contact points, and the footwell multi-color LED keeps the round well visually warm during evening soaks.
The rotomolded unibody cabinet, available in Espresso or Coastal Gray, makes the Splendor visually distinct from the square Fantasy models, its silhouette reads more like a freestanding decorative element than a traditional rectangular spa.

The Splendor is part of the lineup carried by Seven Seas Pools & Spas. Call ahead or stop by your local showroom to confirm current showroom availability. Visiting a showroom is the fastest way to experience the round barrier-free layout, test the diverter-valve whirlpool mode, and see the cabinet finishes on the models currently on display. Call or visit your local Seven Seas Pools & Spas location to schedule a private wet-test soak appointment with the models currently on the floor.
The Splendor is a 115V Plug-N-Play spa, the GFCI power cord is included, and a standard 15-amp exterior outlet on a dedicated circuit is the only electrical requirement. A 230V hardwire conversion is supported if you'd prefer faster heat-up and the higher 4 kW heater output. Site requirements:
Level concrete pad, deck, paver base, or prepared spa pad capable of supporting 3,450 lbs filled
18-24" minimum service clearance around the round perimeter for equipment access
Standard exterior 115V GFCI outlet within reach of the spa cord (or a hardwired 230V circuit if converting)
The 6'6" diameter is consistent across the cabinet, households planning a deck cutout or a recessed install should remember the round footprint requires a circular cutout rather than a rectangular one. Seven Seas offers full delivery and installation service, including site assessment, GFCI verification, and post-fill water balancing.
Week-to-week maintenance reduces to inserting a fresh FROG® cartridge when prompted (typically every three to four weeks depending on use), checking the 50 sq. ft. filter monthly, and refreshing the water roughly every three to four months. The filter care guide and water care service in the owners area cover the full routine, and a separate winterizing guide addresses cold-weather draining if you don't run the spa year-round.
The Splendor fits households who want a social, conversational round soak with the freedom to stretch out, friends gathering, families with active kids, or if you specifically want a round spa. The diverter-valve whirlpool mode is a distinguishing feature that no other Fantasy model offers.
Caldera certifies the Splendor to California Energy Commission (CEC) and APSP 14 standards, a useful efficiency proxy if you live elsewhere. Actual monthly electrical cost depends on your local utility rate, ambient temperature, soak frequency, and whether you run the heater on 115V (1 kW) or convert to 230V (4 kW). Ask a Seven Seas advisor for an operating-cost estimate based on your climate and electricity rate.
Yes, that's the headline buying advantage. The Splendor ships with a GFCI power cord that plugs into a standard 115V outlet on a dedicated 15-amp circuit. Caldera's product page states: "No special wiring. No added plumbing. Just fill your spa, plug it into a standard 115V outlet, and enjoy the first of many comfortable soaks." No electrician is required for most installations, confirm your outlet is on a dedicated circuit and protected by a GFCI breaker.
The diverter valve is a manual control that routes water flow between two modes: personalized massage (water directed to the perimeter Mini and Twin Pulse jets) and whirlpool feature (water concentrated through the central Turbo Jet to drive a high-volume circulation across the whole tub). It's a single-spa way to switch between targeted hydrotherapy and a more immersive moving-water experience.
No. The Splendor is FROG® Sanitizing System Ready, a cartridge-based system that releases sanitizing minerals and either chlorine or bromine. Salt-water sanitization (the FreshWater® Salt System or FreshWater® IQ) starts in the Vacanza® Series and above. See the salt-water care guide for the broader trade-off.
Yes, a WeatherPro™ 4" Tapered Core cover with a hinge seal and curved front skirt is included. Cover colors: Gray, Cocoa, Black. Optional Low Mount or Cover Rx lifters are available, and the optional Curved Roto Step matches the round cabinet shape.
Caldera does not publish a single warranty page on the product page itself. Seven Seas walks every Splendor buyer through the current Caldera warranty document at the time of sale, generally a multi-year shell warranty plus shorter components and labor terms. Ask for the latest warranty PDF when you visit a showroom.
Yes, with proper planning. The 115V plug-and-play option simplifies the electrical side relative to higher-tier hardwired spas. Indoor installations require a moisture-resistant floor structure rated for 3,450 lbs filled, active humidity ventilation, and floor drainage planning, and a circular footprint to plan around. See indoor installation guide for full requirements.
