We are all most done, when she states I want a HEATED floor. My comment was to late dear. I left to go an get some fixtures. When I got back she stated the tile has been removed, I look she in the eye what did you do Said in calm voice I removed the tile so you can install s heated floor me. Needless to say I was not a happy camper when I looked at floor in the bathroom,she had removed most of it, after 40 years with my bride, I did what she wanted and guess what I really like it to. So when start get the BOSS how to so you have to redo.
