Five infrared heat panels and four red light heat bulbs allow this sauna to reach up to 150 degrees infrared. Unlike other saunas, the infrared heat warms your body from within, making it feel like you are experiencing 200+ degrees and encouraging deep relaxation and detoxification. The Sweat Box Sauna is compact and runs on a standard 110v outlet, so it can be used in a home gym or a professional studio.
