dianne8888 How did you build the wing wall on the shower to be strong enough so grout doesnt crack?

Scott Haig, CKD You are right on the mark, dianne8888! We used diagonal cross bracing inside the wall which made this wall just a little bit thicker than a typical stud wall. In short, we planned to make the wall beefier and as stable as possible. The shower side is sheathed in cement board, which along with the large tiles, actually added to the stability of the wall. Thanks for asking.
