Leveling out plywood floor before tiling


I am going to re tile my bathroom but when I picked up the old tile I found a rotted floor where the toilet was. I have since put down new plywood but there is a little lip on the edge of the new/old plywood. If I am going to put down backer board will I need to level out that lip or will the mortar and backer board compensate for the difference? The difference is small maybe 1/8" at most. Thanks for any advice!

Adam,

1/8" is HUGE. The seams need to be within 1/32" of each other. Did you install blocking under the new seam?

Are you sure you used the same thickness subflooring?

Jaz,

I may be wrong about the difference. I did put blocking underneath the new plywood and it is the same size as the existing plywood. I will post later what the actual difference is but let's say 1/16" is the difference. What could I do to compensate for this? Would the mortar and the backer board be enough to fix this? I would rather not have to take up the new plywood to fix this problem.

Thanks,
Adam

Depending on the amount, how much was replaced, the lay-out, and which is lower, I might let the thin set under the backer do the supporting but put the fasteners in strategic locations to help things. In other words fasten the high side where the transition happens and not the low side for at least 8" or so.

If you placed blocking under the seams you should be able to get away with just a single subfloor. How big a piece did you install? New patch needs to rest on 3 joists, two is not enough.

Here are a couple of pics. I did the repair in 2 different sections. All of the new pieces are secured by all 4 sides with sistered joists and some perpendicular supporting pieces in between the joists. This is very solid. I just measured and at some points it is a little over 1/16" to flush with the old pieces.
