The other thing. Behind the tile will be sheetrock, not cement board so if you plan on only cutting up 4 inches to remove the first tile, it may be a hassle cutting out the old rock if its still solid and cutting a piece of cement board to fit that, Remember it has to be perfect smoothor its foing to look like balls when you retile it. You may be better off taking off at least 2 courses so you can kinda float the cement board and tile if you know what I mean.
