QUESTIONHow Can I Heat my Ceramic Tile Floor? - IS THERE A WAY OF HEATING A BATHROOM TILE FLOOR FROM THE BASEMENT BELOW. IS THERE SOME PRODUCT THAT CAN BE ATTACHED TO THE SUBFLOOR BETWEEN THE JOISTS IN THE BASEMENT?
ANSWERANSWER - You could probably install some type of heating device on the bottom of the wood subfloor between your joists, but I wouldn't expect it would be very effective. Wood is not a good conductor of heat for transferring it up to the bathroom floor surface, and you would have to insulate it to keep the heat from transferring elsewhere. Plus it could be a safety hazard.
Best option is to remove the existing bathroom floor finish and install a floor warming system and then install ceramic tile or stone on top of that.
