how to deal with a bulky bathtub fastening lip when tiling the walls

my replacement bathtub is made of a thick plastic coated in an enamel. I assumed the durock backing could easily be installed over this lip but its bulk isnt going to make for a smooth transition. I assume this could be a problem even with more forgiving tub so is there a standard way to deal with this issue?

do I stop the durock at the top of the lip but cover the lip with my tile?

do I shim out the walls with some lumber before adding durock to bring the durock flush with the face of the lip?

Any advise would be appreciated

Is this a drop in tub? If so, I would add adequate support to the bottom to bring it above the cbu and tile, install the cbu and tile. Others on the forums prefer to let it sit on the cbu (with support of course) and tile to the edge.

Install the cbu 1/4" or so off the flange. The tile will overhang the CBU slightly. You may need to fur out the studs so it doesn't bulge at the tub.

Thanks guys..

So i guess the answer is furring or shimming out the wall studs to accommodate. should I fur out the entire wall or just the bottom 16'' or so to make for a smooth transition. Will only furring out the bottom create a noticeable change in my tile cuts when i get to the lower inside corners?

Some more options:

1. notch out the studs so the flange is flush with the studs.

2. Have the board come to 1/8" ABOVE the flange (tile will overhang some)

3. Shim out the entire stud(s)


You don't want to shim just a few inches of the stud, because your corner tiles will not square up.
