The Knox Infrared Sauna features tinted 8mm tempered glass that retains heat and gives you a real sense of privacy, even in a shared room or open floor plan. Stretch out on your own or share the bench comfortably side by side. Eight infrared heater panels heat up quickly to deliver full-body coverage, and it plugs into a standard 120V outlet with no electrician required. Red light therapy, chromotherapy, and Bluetooth speakers all come standard. Ideal for couples or solo users who want a fast-heating indoor sauna for recovery, relaxation, and light red-light therapy sessions.
