How to put backer board on top of the tub

Should the backer board come over the lip of the tub and come down all the way on top of the tub? Also how far should the tile come down on the tub?

Backer to the top of the tub

Before you install your 1/2 inch backer,Please make sure that the studs are tight to the tub.

If not sister up new studs and make sure the wall is flat.

The backer board rests on the top edge of the tub.
The gap is filled with mastic or firmset as you tile.

You will bring the tile within 1/8 inch of the top of the tub.
A good silicone caulk applied after grouting will finish the tub tile joint.

I have never seen a level tub,Do your layout so that you have a cut tile at the tub top.Trying to start at the top of the tub will not work.--MIKE
