Subfloor repair around toilet?


I am adding joists to the shower right now. My question is about the toilet area. As I've looked at the existing flange and piping, everything looks in very good shape. As I said reinforcing under the toilet is going to be very hard because of HVAC ducting right under the floor making adding cross joists impossible. It seems that anything I do to try and cut and replace, it won't be as strong as the existing subfloor (since the present subfloor spans multiple joists and goes under the walls.

I was considering instead perhaps I could just run the new layer of 5/8" ply over the existing subfloor around the current toilet flange and add a flange extender? It seems like as far as the strength of the floor this might be optimal?

bernieb: Sorry I miss spoke, trap was under the shower, not under the toilet.

bob22: never considered putting masonite just 5/8 acx.



Thoughts?

Optimal? No. Entirely replacing all the sheathing would be optimal, and you can add enough thickness to it to get to the closet flange's height. In my opinion anything less is a band aid for a bleeding wound that needs medical attention.
