All houses have quirks or defects. Houses settle; sheetrock is hung out of plumb. I think crown will give you more camouflage than bullnose edging. Buy a small piece of poly crown and test it out. I think you will find it works. Good luck!

Keako, how are you planning to finish the shower? I presume you are going to enclose it with glass. By the time you add all the finishing touches, only you will notice the slight differences in wall heights.

That small area at the top will not be noticed if you use a tile cutter and carefully cut tiles. You might lose a few, but it is worth it to get it right. You've done a great job so far, just finish it on up and put a small bead of silicone at top edge. As it stands now, it looks unfinished at the top. Also, you really need to finish it to the ceiling to keep moisture from getting down behind the tiles. YES, it will over time. Plus you run the risk of unseen mold growing.

I wouldn't install any glass until the tiling is all done. Right now you have space to move unfettered and you don't have the risk of scratching or breaking the glass.

I hope that is not the case Kivi , I would tile right to the ceiling I think any kind of molding will just call attention to that area.

I think you made the right decision not to go to the ceiling. It does really stand out. It would be nice if you can have a bullnose tile as your top row rather than just leave it as is. Don't know if you can get another row off or not at this point without damaging something else in the process. Just be very careful about where the top of the shower glass goes because it will create a sight line that could emphasize the unevenness of the top row. I would keep the top of the glass below the top of the tile for this reason.

I would suggest running a bullnose tile across the top - I am assuming you have bullnose tile down the two sides so it would match up. If that is not bullnose on the sides, how do you plan to cap that off?

Are those screws going right thru PVC liner on top of your curb? Im seeing major mistakes there ...you are missing lath and mud.......Id put the brakes on the tile cosmetic design aspect and look close there at your curb and total waterpoofing ....sorry to bring the bad news......very concerning.

Kivi, I think you misunderstood. We are discussing stopping short of the ceiling and using bullnose as the top row instead of some type of crown molding that will just call more attention to the unevenness.

Buy some matching 6x6 tiles and cut successively taller tiles for the top row. i.e 3 5/8" x 6" at the left, then progressively taller as you go to the right with the last far right tile 4 3/4" x 6". You will never notice the subtle change in height from tile to tile.

2 year old post. I'm sure it's resolved.

We are having this same issue with our subway tile - what was the solution?

I’m having a similar issue. What was the solution?
