porcelain tile directly over old vinyl tile, with radiant heat?
Hi, I've been slowly upgrading my kitchen all year. Now I'm probably going to install porcelain floor tiles.
Does anyone have warnings about installing the new porcelain tiles right over the existing vinyl floor "tile" (if you can call it that), which is in good shape and not peeling anywhere? The tiler who did my backsplash normally puts down 1/4" backerboard on the vinyl, but reluctantly thinks it should work without it, too. The floor tile will probably be on the large side, at least 16"x16".
But I'm also thinking to install radiant heat (probably hot water tubes) between the joists under the kitchen. I'm not sure if this would affect how I install the tiles above it.
Thanks in advance for any insights!
