I am remodeling a half bathroom in my 1925 house. I've removed the existing tile floor which I believe was put down about 10 years ago. Under it was 4 planks of the old hardwood near the doorway and 3/4 inch plywood the rest of the way. See the attached picture for what I have to work with now.
I want to continue the hardwood from the hall into this bathroom. What do I do about 1) the missing subfloor around the plumbing and, 2) the joint in the waste pipe which is at least 3/4 inch higher than the old subfloor. The plywood was just put over the pipe and it bulged and was covered with tile. Being under/behind the toilet, I never noticed it until I got the toilet out.
Should I just lay the hardwood over the gaps in the subfloor? What about the waste pipe? Could it be moved so it doesn't bulge above the subfloor? Should I put down a thin layer of plywood and cover with 5/16 hardwood?
I want the hardwood to be seamless from the hallway into the bathroom.
Thanks for any advise.
