Surround over Plaster walls?
I have a 100+ old house and has an old freestanding cast iron tub that has to go, I would like to replace it with an acrylic tub and surround but was wondering if it would be ok to install it over the exhisting plaster walls as i am not relishing the idea of taking down plaster and lathe. It says to install directly over studs, but most of the surrounds i saw say that, so what do you think? Is there a reason for installing to studs? If i do, is there anything i should do to the walls first before i install?
Thanks for any help!
