These photos speak for themselves. There was a tile related error... It's lucky I came home when I did before more got put up.
Tile is extremely difficult to remove, as I now know firsthand.
I got about 2/3rds of them off intact. They all took the paper off the backer board with them. At least I managed not to damage the rows left on.
I had a perfectly good house at one time... If you are considering a remodeling project, take my advice, don't do it.
