I have received conflicting advice about remodeling my pink and green very 50s bathroom. I am thinking of removing the wall tiles and then using 3/8 cultured granite panels around the bathtub. Standard size; walls and ceiling quoted about $1500 for materials. However, a tile guy says I should replace the old tile with new tile, that I'd save a lot of $$. Another guys says that the wall tile is set in 4" mud and will be very difficult to get out. Any way to know who is right?
