I am going to tile a bathroom. I have removed the linoleum and all adhesive. There is a 1/4" plywood layer over the original subfloor. The floor is dry and clean. Do I need to remove the plywood subfloor before installing the backer board and tile?

Best Answer
If your plywood floor is in good condition, I would drive screws to securely attach it to your floor beams. When I did my floor, I saw they were attached with nails which was not ideal even though I had no squeeky issue.
