When one of our technicians comes out measure your bathroom shower, he'll use a six-foot level to test your bathroom walls and floor (and ceiling for airtight enclosures).
About 75 percent of the homes we work in do not have perfectly straight walls, so we have a lot of experience trouble-shooting tricky surfaces.
Frameless showers on out-of-plumb walls blend in better than framed showers do. Our solution here is to cut the glass out of square so it will lie flush againt your out of plumb wall.
