Re: Steam room finished Next up: lighting, controls, fixtures. LED lights in ceiling with a marine switch panel in the wall to control them. The switch panel also controls on/off for the steam generator and has a thermocouple to sense the room temp. Everything in the room is 12v and waterproof.
In the basement, there's an industrial temperature controller that turns the steam generator on and off to maintain 110 +- 2*F.
