The TheraSauna two person sauna is the ideal solution for those who want to detoxify, lose weight, or who are recovering from an injury. It easily accomodates two average size adults. This is our most popular and versatile model.At the heart of the TheraSauna is the TheraHeat system of heaters and patented, solid-state digital controls. The controls regulate the level and temperature of infrared waves emitted by the ceramic heaters.The TheraMitters warm the body - not just the air as a conventional sauna would. TheraMitters are ceramic heating elements that operate with a 96% efficiency, and reach their maximum output in five to six minutes. Other saunas use a radiant heater sheathed in a metal tube that has a radiant efficiency of only 50%. TheraMitters absorb and maintain radiant heat to exacting temperatures and have an operating life of over 10,000 hours. Theramitters also feature a limited lifetime warranty.TheraSauna portable units are handcrafted of 100 percent clear, non-toxic Aspen for years of durability and lasting beauty. Other saunas are constructed from cedar and redwood which contain a volatile oil called Cedrene. When cedar or redwood is heated it creates toxic gases that are inhaled and absorbed through the skin. TheraSauna"s non-toxic wood gives off little or no toxins.The TheraSauna Plugs into any 120-volt outlet and can be easily set up in about 30 minutes. There are plenty of low cost imitators out today, but only one original TheraSauna!
