It did. The problem is a combination of lack of experience and that the acrylic shower wall kit I purchased was not flat, it had contours all over the damn place. Had I installed just flat waterpoof backing board and then tiled it, it would have been easy as hell. But the shower wall kit had all kinds of curves and contours. Something I didn't think about until it was too late into the project. (the depth of the acrylic shower was not the same across the width). A ridiculous design flaw in terms of making installation easy.
