I have a person at work who's wife is disabled. They had a special shower built, and she is freezing in this shower. I can't get above the ceiling, and I am not sure of the legality of a heating unit over the shower. The exhaust fan / light only has #14 wire to it and is outside the shower anyway. I can get to a closet behind the shower, and duct it in. Across from the shower is a wall with a hydro-therapy tub on the other side, so I can't put anything there either. Does anyone know of a small 500 to 1000 watt ducted electric heater?
