I recently ripped out a 4' x 4' section of tile in hall at the front entrance of my house which I am looking to replace with new tile. My issue is the sub floor is 1x8 tongue and groove planks installed 45 degrees and I only have 3/4" of room on top of the T&G sub floor due to my front door. I know normally you would add plywood and then the backerboard and tile on top of that but that would put the height too high.
So are there any options for what I can use for underlayment to get me my 3/4" ish total height which includes the tile (1/4")? Could I just add some 1/2" backerboard over the T&G and tile on top of that?
Or maybe I cold use Ditra over 1/2 ply. Can you buy that in anything but large rolls?
BTW...The old tile was just installed on top of a 1/2" bed of cement and wire mesh. The tile came up pretty easy...
