Yes, it is on the main wall and I knew I had to bump out the entire wall. However, now the tub is installed and I see that the room is not square. There is a 1/2 gap at the tub wall corner, then gradually a 1/4 inch gap at the front of the tub. I found 1/4 inch strips that will work perfectly, doubling up for the 1/2 inch gap. Then, the rest of that wall is actually 60 1/4 inches. Since it seems to be a gradual difference from the 1/2 to 1/4, there should not be any issues with my alignment of drywall and wedi, correct? Will there be any tile issues with the difference? I’m using 12 x 24 in tile in the tub surround.
