The sauna device includes a sauna room enclosed by a floor and a wall forming a box shape, a first heating body installed on the wall such that a user enters the sauna room and receives the radiating heat, a chair provided in a lower front portion of the first heating body and including a seat and a back plate, and a second heating body received in the back plate, which can increase the quality of the sauna drastically since the non-heating portion can be complimented through heating body embedded in the waist support and delivers radiating heat to the hip portion effectively.
