I would like to put a tile surround 18" up around a tub. I have discovered that that while the walls are vertical, the floor is not level. Indeed one end of the bathroom is 2 inches higher than the other, if my black and decker laser level is to be believed. (Hmm. Check that.)
In a couple places the drywall has cracked, so the room has moved since the was drywalled 30 years ago.
I have visions of tiles (6" ceramic) popping of the wall if the house continues to shift.
I'm consdiering hanging a sheet of something by 2 screw at the top edge, with a couple washers behind the sheet as spaces, then using a dollop of silicon seal at the bottom edge. The spacers at the top allow for a reasonable thickness, and attaching tile to the sheet.
The idea is that this sheet is now decoupled from the house movement and can in essence float.
Is this workable?
