I have cultured marble shower walls along with a marble floor. I'm considering having the whole thing removed/demolished and installing tile. However, I want to be able to know how the process of removal is done in order to hire someone who will do it correctly without damaging my wall studs.
It's probably glued to the studs. You'll probably have to pry it off. This could mess with the wall covering on the other side. Once you gained access to an edge of the walls, you might be able to use a sawsall to free it from the studs.
See what other suggestions you get...
