Bathroom built in 1959. Tile around tub and up 5' or so has 4x4 tile, adhered quite well onto regular wall board (maybe green if they even had it back then), its in very good condition, but the color is pink and the tub is peach, looks crappy. Is it realistic to believe I can pry these off and re-tile? The walls are sound all around. I'd end up with either mastic on the walls or tearing off the paper, can either of these be dealt with? The complete tearout, of course, is an option, but I think the non tearout option would be less traumatic for the wife...
