Tile over tub lip.

Hello i will be installing a acrylic shower pan with a 2 25 high flange lip and its 1 4 thick i will be installing 1 2 durock 1 8 above it at the bottom with backer rod and a 100 silicone bead now how far down do i over lap the first row of tile over the durock on the bottom if any. 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. Apply it to the wall with the bottom edge about 1 4 in.

Divide the dimension in half and make a mark there. The tub is designed to sit on the floor and be screwed to the studs kohler recommends setting in mortar which i did. That s cuz the formula for the deflection of a beam has the beam s height cubed in the denominator. 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.

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. 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. 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. Fill the gap between the tile and the tub with caulk.

Then apply a generous amount of thin set to the bottom bathtub tile and position it 1 8 in. By using the right kind of materials and tools it is possible for you to tile over the tub flange with ease and efficiency. Above the lip of the tub.
