I've used heating cable in several bathrooms, installed under the tile. I'm pleased with it.

AFAIK It is meant to warm the floor, it is not meant to be the primary source of heat.

Thank you! We will also install a mini split system in that room. Porcelain tile can be quite cold so we though we should try and warm it up a bit for comfort.

I used Warmly Yours in two bathrooms.

There are several ways to install. I tacked the cable and the floor temperature sensor to the subfloor. Then poured self leveling cement (it's the consistancy of pancake batter) over the cable, and installed the tile.

Thank you again....My husband is checking that product out this morning! :)

We used the in-floor heating grid from Warmly Yours, and embedded the cork insulation, grid and temp sensor under self-leveling cement before the tile was put in. We don't have it set to get really warm (75 degrees, I think), but that definitely makes the tile floor in the bathroom feel very comfortable.
