The Bloom™ is a five-person hot tub from the Fantasy Series, the entry-tier hydrotherapy line manufactured by Caldera Spas, a Watkins Wellness brand. Measuring 6'6" square and holding 265 gallons of water, the Bloom carries the highest jet count in the Fantasy lineup at 40 jets across three configurations. It runs on a standard 115V outlet (with optional 230V conversion), uses a rotomolded unibody cabinet, and ships FROG® Sanitizing System Ready. The Bloom is smart-sized but spacious, built to put wellness and fun within reach at the entry tier. The Bloom is sold and serviced through Seven Seas Pools & Spas.

(1.98 × 1.98 × 0.86 m)
40 total (8 Ultra Mini, 26 Mini, 6 Twin Pulse), highest jet count in Fantasy
FROG® Sanitizing System Ready
The Bloom fits households where multiple adults soak together, families with teenagers, couples who entertain friends, or groups of friends sharing a deck or backyard. With five-person capacity and 40 jets distributed across three jet types, it delivers the most "social spa" experience in the Fantasy tier without stepping up to the Vacanza® Series. The 115V plug-and-play install (with 230V conversion option) keeps electrical complexity off the table for most owners. The durable rotomolded unibody shell is stylish and budget-friendly.
The Bloom pairs five-person open seating with 40 jets, exterior lighting, and a waterfall while keeping plug-and-play ownership within reach.

The Bloom is a social, multi-seat soak rather than a single-occupant hydrotherapy lounge. Five seats arranged around an open footwell let the household share the spa simultaneously, with the 40-jet system distributing pressure across every position. The Ultra Mini Jets add fine focused massage to specific muscle points, the Mini Jets carry the bulk of the back-and-shoulder coverage, and the Twin Pulse Jets deliver pulsing rhythmic pressure across primary contact points. Add the footwell multi-color LED, two external accent lights, and the integrated waterfall, and the Bloom shifts from purely functional hydrotherapy into evening-entertainment territory.
The Bloom's rotomolded "unibody shell" is meaningful past styling, it makes the spa exceptionally durable (no seams to fail), keeps dry weight low at 425 lbs, and supports faster, simpler delivery than seamed-shell spas in higher tiers.
Choose the Bloom when you want a social Fantasy Series spa with the lineup's highest jet count, simple 115V setup, exterior accent lights, and an integrated waterfall.

The Bloom 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 3,515 lbs filled
18-24" minimum service clearance on at least one side for equipment access
Standard exterior 115V GFCI outlet within reach of the spa cord (or a hardwired 230V circuit if converting)
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 Bloom fits households where five adults, or a family with teenagers and frequent guests, want to soak together. It's the highest-jet-count Fantasy model and delivers the most social spa experience in the entry tier without stepping up to the Vacanza® Series. It's also a strong fit if you want plug-and-play simplicity but need more capacity than the Aspire® or Invite™.
Caldera certifies the Bloom 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). With 265 gallons of water, the Bloom heats and re-heats faster than larger Vacanza or Paradise models. Ask a Seven Seas advisor for an operating-cost estimate based on your climate and electricity rate.
Yes. The Bloom 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." No electrician is required for most installations, confirm your outlet is on a dedicated circuit and protected by a GFCI breaker.
On 115V, the heater runs at 1 kW. Convert to a 230V hardwired connection and the heater steps up to 4 kW, heat-up time drops significantly, and the heater can run while the jets are on high. The conversion requires a licensed electrician and a dedicated 230V circuit. Most Bloom owners stay on 115V because the convenience outweighs the longer heat-up.
No. The Bloom 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 are Gray, Cocoa, and Black. Optional Low Mount or Cover Rx lifters are available.
Caldera does not publish a single warranty page on the product page itself. Seven Seas walks every Bloom 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. Indoor installations require a moisture-resistant floor structure rated for 3,515 lbs filled, active humidity ventilation, and floor drainage planning. The 115V plug-and-play option simplifies the electrical side relative to higher-tier hardwired spas. See indoor installation guide for full requirements.
