These products are constructed with the environment in mind which accounts for the efforts. This all translates to a quality sauna that retains heat more efficiently, heats up faster, and wastes less energy. The heating panels are 30% larger than saunas heated by tubes and penetrate skin 40% more to maximize therapeutic benefits. Unlike ceramic heaters, you will never have to replace this product. This product also heats up 30% faster than saunas equipped with panels and 100% faster than rock and water steam saunas. The 2-person sauna is designed for ease of use and is an outstanding value. Every sauna is equipped with a reduced wattage floor and lower bench heater to allow the same benefits and treatment to your legs and feet without the burning sensation of other sauna manufacturers. This sauna enhances your sauna experience with the bonus feature of the Chromotherapy (color therapy) lighting system. This sauna plugs into any dedicated 15 amp 120-volt outlet so no special wiring is required and it may be installed on carpet and at any indoor location including the basement, garage, master bath, or walk-in closet.
