Sorry for not replying sooner, tried to access website but the page wouldnt show.
I'll try to explain better...
The tiles are butting up to each other, in the corner of a shower, (corner shower unit)
if i keep the tiles level, from the floor upwards, by the time i reach midway and higher, there is a gap between the butted up corner tiles, of about 1-1.5 inch, due to the wall not being level.
I used a level for the horizontal and a plumb line for vertical, i didnt flip the level so will double check
Thanks for everyones replies so far, sorry enduro for not ringing, thanks for the offer of help.
If the tile marks are correct...
Is there a way to keep the full tiles even, all the way to the top?
Would putting a baton midway and tiling up from there, then cut the tiles below the baton to fit the corner work?
Or is there another way to acheive even and level tiles on such an uneven wall?
