Sink into the warm, bubbling Lay-Z-Spa Rome Smart AirJet 7 hot tub, created by the world’s first portable hot tub manufacturer. A relaxing soak in heated water is great for releasing muscle tension and supporting exercise recovery. Featuring the patent-pending EnergySense multi-layered insulation, this hot tub is up to 40% more energy-efficient than similar inflatable hot tubs. The Bestway Connect app allows you to set your spa to the perfect temperature, activate the Power Saving Timer, run the water filter and control the massage system - all from the palm of your hand. The AirJet system features 180 jets that release bubbles from the bottom of the tub to create a relaxing environment. MaxHold fabric internal beams provide superior air pressure retention, stability and lightweight portability. The external wall is constructed with 3-layer Tritech material, proven to be both puncture and damage resistant. Designed with innovative Freeze Shield technology, internal temperatures stay just above freezing when not in use to prevent damage during colder seasons. This hot tub set features a multi-function UltraFit pump that runs the inflation, heating and filtration systems, ChemConnect dispenser that maintains the appropriate chemical level, and a reinforced cover to keep heat in and debris out. Our spas feature a Ground Detection System that ensures the spa is used with an outlet having a proper ground connection, providing additional electric current protection.
