One of our most popular models, the S-820 is perfect for one or two people. With its footprint of only 13.3 sq. ft., this IR sauna has the same luxurious features as all S models: Pure Infra Low EMR/Low EF, all-glass front wall, valance and bench skirt lighting with white lights and color light therapy. It can be easily incorporated into an in-home workout area, or even in the master bedroom.
