Long story short: my contractor cheated me & I'm repairing it myself.
He left an 8-inch by 6-foot gap in the bathroom subfloor.
I hope it's ok I simply cement-board the whole thing and then tile over it? Is 8 inches too long a gap for cement board?
If it *is* too long, would it be easier / cheaper to have a plumber lower the pipe, or to cover the entire subfloor (about 7 feet by 4 feet) with...what, plywood? How thick should the plywood be?
Here is a picture of my predicament :

A floor should have:
1. a 5/8" layer of plywood subfloor,
2. a layer of roofing felt for moisture barrier, IF it's over a basement or crawlspace, and
3. a 3/4" layer of plywood flooring.
Then, if you're laying tile, a layer of cement board.
The toilet flange needs to be raised to sit flush on top of the tile with only the thickness of the flange above the tile. The flange should be bolted to the floor, with the toilet leveled and bolted to the flange.
Good Luck!
