The technology used in this sauna is patented in the United States. It's important to note that the sauna also includes an infrared heating panel on the front door glass, as well as heating panels located on the sides for the calves and the soles of the feet, resulting in a complete 360-degree wrap-around infrared heating experience.Wood TypeCanadian Solid HemlockCapacity2 adultAssembled Dimensions47.4"W x 75.8"H x 39.5"DInside Space44"W x 71.7"H x 36.2"DGlass DoorTransparent / 23.6" x 65.0"Wattage1750WElectrical Requirement120V / 15 Amps (Standard Household Output)EMF LevelBelow 0.5mGComfortable for Body TypeUp to 400 lbs / 6ft 7inC/F Switching MethodPress the (+) and (-) buttons at onceMax.
