The spa includes essential accessories like a pump, chemical floater, filter cartridges, and a repair patch, which simplifies the setup and maintenance process. However, despite its benefits, users should be aware that the hot tub has limitations in extremely cold temperatures, and the water capacity at 222 gallons requires careful monitoring to ensure optimal performance.

The heating system is quite effective, capable of warming the water up to 104 degrees Fahrenheit, suitable for a soothing experience even in colder climates, although it should be noted that the tub cannot be used in temperatures below 39 degrees Fahrenheit. The 120 AirJets offer a relaxing bubble massage, which is a significant plus for users looking for a therapeutic soak.

Additionally, the tub comes with essential accessories like a durable liner, heater, ChemConnect dispenser, filter cartridges, and a cover, enhancing its convenience and maintenance.

The Coleman SaluSpa Miami AirJet inflatable hot tub is designed to comfortably fit up to 4 people, with a spacious 71-inch diameter and 26-inch height. Its material is a strong, tear- and stretch-resistant PVC called DuraPlus, which adds durability compared to many other inflatable tubs. The heating system can warm water up to 104°F, providing a relaxing soak, and it includes a Freeze Shield feature to protect the tub’s components in cooler weather — though it should not be used if temperatures drop below 39°F. The hot tub offers 120 air jets that create soothing bubbles, enhancing the massage experience, and is controlled through an easy-to-use panel integrated with the pump system.

Setup is straightforward, thanks to a pump that inflates, heats, filters, and powers the jets all in one unit. The included insulated cover helps retain heat and keeps the water cleaner between uses. On the downside, the water capacity is fairly large at around 177 gallons (when 80% full), which means filling and draining can take time, and the tub’s plastic material, while durable, is still more vulnerable to punctures than hard-sided tubs. Also, some states restrict sales of this model, which limits availability. Maintenance involves chemical balancing and cleaning filters, which is standard but requires regular attention.

This inflatable spa suits users seeking a portable, easy-to-set-up hot tub with solid heating and bubble features, making it an ideal choice for small groups wanting a casual outdoor spa experience.
