Question

Drywall on a concrete floor


if I am installing drywall on a concrete floor (before I tile) do I let the drywall sit on the floor or raise it just a hair off of the floor. This is a basement bathroom.

Are you serious? Don't even attempt to install drywall on any floor...anywhere.

Keep it a 1/2" off the floor. I hope you mean you're installing drywall on a wall with a concrete floor.

Are you kidding? We use it all the time under floor tile. Just have to make sure you use greenboard.

Hopefully that is a joke Jerryh3. You're kidding, right?

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?

And so I am assuming that when I begin tiling I tile under that 1/2" gap?

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

You don't have to. The baseboard will cover the gap of the wall to the tile.

Always hold up the drywall in a bathroom off the floor enough so that if the toilet runs over that the water will not wick up the wall.
