I am remodeling my bathroom, and intend to replace my bathtub and surround. I have started ripping the 5/8 in. drywall from around the bathtub, and I intend to install a cement board and tile all the way to the ceiling.
However, the cement board, Hardiebacker, is only 0.42 in. thick, so I will have almost a 1/4 in. difference in thickness between the cement board and the drywall adjacent to the tub. What can I do to transition properly between the 0.42 in. Hardiebacker cement wall and the 5/8 drywall so that my tiling will look good and smooth?
I have not done a tub surround before, so I am not really sure what the smartest way to handle this.
