I have a small room with a shower stall, toilet and pedestal sink. The floor space is about 48" x 56". It is located in the corner of the house, so 2 walls are outside walls. The house is in western NC. While the room is comfortable as far as air temperature, the tile floor is cold. There is one register in the floor on one of the outside walls. The area below is garage, so it could be accessed from below by removing a piece of garage ceiling drywall and insulation. I would like to use the area below the the small bathroom as a heat plenum, hopefully warming up the floor. I know people (including me) will say, "you can't do that ....." But in my house and in many other houses in this area, they put the heat registers for the kitchen and bathrooms (not this bathroom, but the other one) in the cabinet kick plate. The duct just comes through the floor and dies there. The air just pressurizes the "kickplate" area and it eventually comes out of the register mounted up front. So if I were to wall off the area directly below the floor, insult the sides and against the garage drywall, and just like the kitchen cabinets, let the air find its way to the register. I would have to put a shut off on the duct for summer use or suffer an even colder floor in the summertime. BTW, the heat comes from a heat pump with a propane furnace for backup heat. Any comments pro or con or other ideas?
