We use it all the time under floor tile. Just have to make sure you use greenboard. Last edited by jerryh3; 02-21-2009 at 05:55 PM.

Tripower, if you're talking about installing drywall on the concrete floor or using drywall as a tile substrate, time for a major re-design. It'll fail miserably. You can install 1/2" cement wonderboard (durock) under your tile, or you can use ditra.

Take a chill pill bro....I meant can the dry wall rest on the floor or should there be a gap between the drywall and the floor after mounting the drywall....to the WALL (before tiling). Who the heck mounts dryWALL to the floor?

Who the heck mounts dryWALL to the floor? You would be AMAZED at some of the things people try 1/2" gap between the bottom of the drywall on the wall & the floor I would tile at the edge of the drywall if I was adding base trim - or out maybe 1/2" to allow for 3/4" trim If not I would tile slightly under the drywall
