Trying to figure out what I'm going to do. I have been given the task to remodel the bathrooms in my church. Currently I have tile over concrete. We don't want to go to the expense of replacing the tile but no one likes the look of it. It has been suggested to glue dry wall directly to the tile. In the back of my mind that seems like poor craftsmanship. Not to mention the many other problems that come with adding thickness to the walls and shrinking the room. The stalls won't fit and the plumbing will need to be extended. Also the tile only goes 5ft up the wall. I was thinking about putting a shelf with some nice trim to hide the new ledge. I hope to get some good feed back, weather to go ahead and glue the dry wall or something else. Thanks.
