I have a small bathroom on the main floor of my house (about 3'x5'). There is a door in this bathroom leading to my backyard and the bathroom is in the corner of the house - so two exterior walls. This bathroom gets COLD in the winter - even with me sealing up the door pretty tight. The only heat in the bathroom is a 30" hot water baseboard. Anyone have any suggestions on what I can do to increase the heat output? Would it make sense to change out the baseboard to a runtal radiator? Any other ideas? suggestions?
