Hello all. I'm deep in my bathroom remodel and am wondering how big a hole in the subfloor would be acceptable without compromising the tile floor. Specifically, I removed a 2 inch PVC drain and am left with a 2.5 inch hole in the 3/4 inch plywood subfloor. I plan on using 1 ft square tiles. Would this hole, under my cement underlayment, be a problem? I can't patch it from below, so I'd have to cut out a large area, add bracing, and replace with new plywood. My joists are 2x12, 16 inch OC. Thanks.
