We have recently had our bathroom refitted, and tiled floor to ceiling with large ceramic tiles in a brick pattern. However now finished it is obvious that they are uneven. The tiler said it is the tiles. Is this likely or is it just a bodged job - he re-platerboarded the walls prior to tiling so they should be flat?
From what I understand, I'd install either waterproof drywall or regular which you can then seal. You can shim the drywall out where the gap is with furring strips. This will give you a straight surface to put your tile on. This assumes the drywall butts into a corner. You can't put tile on an uneven surface as it just magnifies the unevenness. You might be able to put a molding on to cover the gap. That sounds the easiest and cheapest. Take a picture and show it to some one at a tile store or at a hardware store and they might be able to help.
Most tiles are made to be flat and there are some that aren t. On occasion ( and I m not defending your tiler) tiles can be warped and uneven. Especially when you get into the bigger sizes or tiles that are a bit cheaper. Porcelains tend not to do this but unfortunately some times happens in ceramics. I d have to see a bare or uninstalled ( several tiles) and look at them. So if you have extra tiles look carefully at a hand ful. Set them on a flat surface , look down the edges or use a straight edge on them. Like I said, I m not defending him or her, it does happen and no amount of adjusting will fix a warped tole. It they knew about this while setting the tile, you should have be notified. Any questions you can e mail me through my avatar. GL
