Tile over tub lip.

The tub is designed to sit on the floor and be screwed to the studs kohler recommends setting in mortar which i did. This kohler acrylic tub is thick the flange is more than a 1 2 thick if you run the cement board over the flange and the tile which is about 1 2 thick when thinsetted it will come too far into the tub. And in case you want to know why it s because one 1 2 inch thick board is more than twice as strong as two 1 4 inch thick board sitting one atop the other. Tile are a very common way of finishing the walls in remodeled and new baths as they are impervious to water and highly stain resistant.

As i have it now the inner surface of the cement board is basically flush with the ridge on the tub then the tiles would stick down and overlap the ridge once you figure in for the thickness of the thinset. Check if you need to adjust this mark to avoid laying slivers of tile at the top and bottom. Apply it to the wall with the bottom edge about 1 4 in. That s cuz the formula for the deflection of a beam has the beam s height cubed in the denominator.

And do i seal that with another bead of. The best approach when installing cement board or other tile backer around a tub is to keep the cement board out of the lip area.
