I'm looking at remodeling my bathroom and removing the drywall on the walls, replacing them with something more suitable for covering with tile. At least one part of the bathroom will have a new built-in shower, so the tile needs to go all the way up to the ceiling. Not sure about the rest of the bathroom, it might only go halfway up etc. The question is, how far up should I tear the drywall out? If I go all the way to the top, that involves the corner with the ceiling, which gets messy. Should I just try to carefully cut the corner where it meets the ceiling and tear out the whole thing? Or should I leave a 4 inch strip right below the ceiling? Would it be OK to tile over a small strip of drywall like this? I'm not against doing extra work to make sure things get done the "right" way, I just need to figure out what the "right" way is! Thanks for the help!
