These saunas are made of only Reforested Wood Products to help improve the environment. Until now, most people would have to join a gym to enjoy a relaxing sauna. This home use sauna now makes it possible for you to remove body toxins, increase blood circulation, ease pain from aching joints and muscles, even improve skin tone. This oversized 1-2 person sauna is designed for ease of use and is an outstanding value. The ceramic heating system produces more Far Infrared heat than any other system on the market. Enjoy your sauna session listening to your favorite music through the unit's MP3 audio input with built in speakers, or read your favorite book under the interior reading light. Clasp together assembly is easy as 1-2-3.
