Ok guys, I'm demolishing an old bedroom that at least part of it will become a master bathroom. The problem is the original subfloor is 5/8" plywood with 5/8ths" particle board over the top. There was a carpet covering before I got to it... hehe.
I'm wondering if I can't get away with laying cement board over the top of the P board as the new subfloor instead of having to tear the p board out. The edges of the p board go under the sheet rock wall and the job would be a *****! Any thoughts are highly appreciated. Thanks, Al
