Help corner tile will not go in right
Two of three sides of my tub are leveled. I put batten on two of the three sides. Couldn't put it on the third one because of the shower valve and that side is leveled so not worried about it. Removed batten on main wall and tile the bottom row no problem. Removed the batten on the side wall and I can't get the corner tile to go in straight. This corner is the low spot, I was told. I had to cut a little off the bottom otherwise one side of tile would be on the tub or butt into the tile above it. When I tried to put the slightly cut tile one corner sticks out. When I try to push it in the opposite corner sticks out. How do I fix this?
