I constantly get two questions or comments about tiling shower or bathtub alcoves. One is about how cement backerboard should be installed in relation to a bathtub or shower base tile flange, also called a "lip." Does the backerboard go over the lip or up to it? The second question is about "taping" the seams of backerboard in a shower with mesh tape and thinset. What is the purpose of that and is it necessary? In this video I'll answer both of these questions and show you my methods.

UPDATE: To answer a question that has come up about tiling over the area of the lip I made this video:    • How To Tile Over The Lip Of A Tub Or ...
