I have done some research and mostly I have found that putting cement board on top of plywood is the general answer to tile on wood, but it doesn't really fit my situation as much as I had hoped...
I want to do a little project to cover the corner of my closet where my old cats' litterbox was. They used to pee next to it sometimes so it smells awful! I plan to rip the corner carpet out, bleach the concrete floor, and seal it with poly. I thought about tiling that, but then I got a better idea!
I want to build a small base out of wood and then tile it mosaic-style. That way I can put the litter box back on top (different cat, hopefully not the same issue as the other), and it will cover the area while still looking great and being able to move it if I need to so that when I move out I can put another piece of carpet down and the next owner won't have to deal with a little mosaic in the corner of their closet.
Do you have recommendations on how to do something like that? Do I need to put cement board on the little wood platform or can I tile straight to it? Must it be plywood or can it be something thicker like pine? Tips please, I have never worked with tile before!
