Within the 5 x 8 foot print of my second story bath room my subfloor slopes 5/8-3/4 of an inch! (in the 5 foot width) The floor is "flat" and may still be suitable to be tiled but I'm not sure. Building up the low side isn't practical as it would create quite a toe stubber within the door frame. I'm tempted to rip up the ply and notch the joists to bring everything closer. Any suggestions would be really appreciated. Tom
We use to roll marbles down our dining room floor from end to end, but that's another story. I think it comes down to how much work you want to do. Can you live with it? If not, fix it now or you'll always kick yourself for it.
