Hi....we re-tiled the shower stall with travertine that is a little thicker than the porcelain that was there before. It is a quadrant shower stall and now the surround is just a little out of fit (because I used about 40mm more of the room with the thicker tiles). I would just squeeze the suround in but I'm afraid that it will then bend out the wall brackets and cause leaking. I would try and bend it permanently but am fearful of going too far....any advice? It's a 40mm misfit on a 1200 x 900 surround....
