I've searched extensively and cannot belief that I can't find an answer to this question. The problem is that I am installing a new shower surround and the one end wall is only 30" but the end panel is 31 1/8 " wide. The end panel is designed so that it has a right angle for the inside corner of the shower so that the back wall dimension can vary. The outer edge is where I have trimmed it and I am wondering if there is a trim piece to cover the unsightly edge that I now have.
If there is such a trim piece, where can I get it?
And can I go ahead and install the surround now and put the trim piece on once I find one?
I cannot belief that this problem hasn't been encountered by someone.

 

Eeeew! You bought a 32" surround, which will stop short of a 32" wall end. About all you will be able to do is build out the offending wall with a 2x4 and wall finish (sheetrock if painting, durock if tiling). It will cause a "column" look for that part of the bath, but, as far as I know, there is no "trim" piece available for this.
