Coleman SaluSpa St. Moritz AirJet Inflatable Hot Tub
Our Coleman SaluSpa St. Moritz brings resort-quality relaxation to your backyard with 180 AirJet massage nozzles that deliver powerful, soothing bubbles from the floor of the spa. Designed for up to 7 adults, the St. Moritz features a spacious 77-inch diameter and a generous 28-inch wall height for comfortable, full-body immersion.
We built the St. Moritz with our exclusive DuraPlus™ tri-layer reinforced material that resists punctures, UV damage, and temperature extremes. The digitally controlled heating system maintains your desired water temperature up to 104°F, and our rapid heating technology brings water to temperature 20% faster than previous generations.
Setup takes minutes with our ChemConnect™ dispenser integrated into the circulation system to evenly distribute sanitizer, while the cushioned AirJet floor and insulated cover maximize comfort and energy efficiency year-round.

AirJet Technology & Performance
The Coleman SaluSpa St. Moritz uses our proprietary AirJet system with 180 individual nozzles positioned across the spa floor to create a consistent massage experience. Unlike single-source bubble systems, our distributed nozzle design ensures every seat receives the same therapeutic airflow.
Our AirJet pump draws ambient air, heats it slightly to prevent temperature loss, and releases it through precision-engineered openings that produce billions of champagne-sized bubbles. The digital control panel allows you to adjust massage intensity from gentle relaxation to vigorous deep-tissue stimulation, and the system operates at whisper-quiet levels even at maximum output.
Construction & Durability
We engineer every St. Moritz with DuraPlus tri-layer material that bonds a polyester mesh core between two reinforced PVC outer layers. This construction provides superior puncture resistance compared to single-layer vinyl while maintaining flexibility across temperature ranges from 40°F to 104°F.
The I-beam internal structure creates vertical support walls that maintain the spa’s circular shape at full capacity without ballooning or soft spots. We seal every seam with high-frequency welding that creates molecular bonds stronger than the surrounding material itself.
Setup & Maintenance
The St. Moritz inflates in under 10 minutes using the included high-volume hose attached to the spa’s pump unit. Simply spread the spa on a flat, debris-free surface at least 2 feet from walls or obstructions, connect the inflation hose, and activate the pump.
Once inflated, fill the spa with a standard garden hose to the fill line marked on the interior wall—approximately 269 gallons. We integrated the ChemConnect dispenser into the filter housing so chlorine or bromine tablets dissolve gradually through normal circulation, maintaining consistent sanitizer levels without daily dosing.

Common Questions About the St. Moritz Hot Tub
The St. Moritz typically heats from 60°F to 104°F in 24-36 hours depending on ambient temperature and whether you use the insulated cover during the heating cycle. Our rapid heating element raises water temperature 2-3 degrees per hour.
For faster results, fill the spa with warm tap water if available, keep the cover on throughout heating, and avoid running the AirJet massage during initial temperature rise. Once at temperature, the system maintains your set point efficiently with minimal energy use.
AirJet systems like the Coleman SaluSpa St. Moritz use heated air released through 180 floor nozzles to create billions of gentle massaging bubbles that surround your entire body. This provides a full-coverage relaxation experience ideal for stress relief and muscle loosening.
HydroJet systems use targeted water jets positioned at specific heights to deliver concentrated pressure massage to back, shoulder, and leg zones. HydroJets provide deeper tissue penetration but cover less surface area than our AirJet design.
Yes, the Coleman SaluSpa St. Moritz is engineered for year-round outdoor use in temperatures from 40°F to 104°F. The DuraPlus material resists UV damage, and the heating system maintains water temperature even during cold weather.
We recommend keeping the insulated cover secured when not in use to protect against debris and retain heat. In regions with sustained freezing temperatures below 40°F, consider deflating and storing the spa indoors during winter months to extend lifespan and reduce energy costs.
Operating costs vary by climate, usage frequency, and local electricity rates, but most owners report $20-40 monthly for moderate use. The 1,200-watt heater cycles on and off to maintain set temperature, and the insulated cover significantly reduces standby energy consumption.
Running the filter pump 6-8 hours daily adds approximately $5-10 monthly. To minimize costs, maintain the recommended water chemistry to prevent heater scaling, keep the cover on between sessions, and consider lowering the temperature 5-10 degrees when the spa won't be used for several days.
The St. Moritz requires a flat, level surface capable of supporting 2,200 pounds when filled. Ideal surfaces include reinforced wooden decks rated for concentrated loads, concrete patios, or compacted gravel pads with landscape fabric underneath.
Avoid placing directly on grass, dirt, or unlevel ground as this can cause uneven weight distribution, drainage valve malfunction, or premature wear on the spa bottom. We recommend a cushioned ground cloth or foam mat beneath the spa to protect against sharp objects and provide additional insulation.
With proper chemical maintenance and filtration, change the water every 2-3 months for a family of four using the spa 3-4 times weekly. Heavy use or higher bather loads may require more frequent water changes every 4-6 weeks.
Drain and refill when water becomes cloudy despite balanced chemistry, develops persistent foam, or shows visible scale buildup. The integrated drain valve connects to a standard garden hose for controlled emptying, and the deflated spa can be tilted to remove residual water from low spots before refilling.
The Coleman SaluSpa St. Moritz is designed for traditional chlorine or bromine sanitation using the integrated ChemConnect dispenser. We do not recommend saltwater chlorine generators as the salt concentration can degrade inflatable spa materials and internal components over time.
Stick with EPA-registered spa sanitizers dispensed through the ChemConnect system for reliable water quality and to maintain your warranty coverage. Alternatives like mineral purifiers can supplement but should not replace chlorine or bromine as your primary sanitizer.
