I’m getting ready to get started on putting tile into what was my laundry room. It is now going to be a mudroom/entry-room from the garage, as the laundry has been relocated to the basement. Currently the room has vinyl sheet-laminate flooring.
I am looking to know what backer-board to put down before tiling (or none?). I have thoroughly confused myself reading the tile DIYs and threads. I have done floor tile before, but only on concrete floors. What is the correct backer material for this installation, and how should I affix it (Just screws, screws plus thinset, etc.)?
Facts:
- The room is 5.5’ x 10.5’ (it's like a hallway).
- I have 13” porcelain tiles that I will be installing.
- Floor Joists are 2x10s, 16” O.C. and span the short width (5.5') of the room.
- Subfloor is 23/32 OSB.
- This is on the first floor of a 2-story house, with a full basement below.
Any other info needed for a recommendation, let me know. Thanks in advance!
