Im in the middle of a bathroom remodel and noticed some water damage on my subfloor. My house is pretty old, from the 60's and I know the bathroom has not been remodeled since then. I decided to rip it all out and replace the subfloor for the room. The subfloor I ripped out is 1/2 and had a full inch of poured concrete between the subfloor and the tile. I decided to go with a 3/4 plywood to give the tile more support - I plan on using the schluter ditra over concrete backerboard, it looked easier. My question is will I have a difficult time fitting the 3/4 subfloor when the rest of the house is 1/2 inch? I know I will have some more space since the concrete was so thick Thanks - this is my first major floor job.
