		I'm laying rectangular tile in a brick pattern in a walk-in-shower.  I don't know how to make the grout lines align with the ceiling and two side walls with this rectangular tile.  Should the back wall and ceiling grout lines line up continuing the brick pattern?  Should I forget about the two side walls having grout lines that align with the back wall and celing?  If  have to choose, which walls should have the grout lines align, the back wall and celing forgetting about the sides, or the side walls and celing forgetting about the back wall?
Thanks
