We are looking to renovate our bathroom. The current tub enclosure is the basic plastic/vinyl that has seams ; there is a window in the upper part of the wall that the bath is on. Behind that is the old lathe-and-plaster. I know I can put in another vinyl tub enclosure, or tile if I put up wallborad first, but looking to see if there are other alternatives. The house is 100+ years old and there is no room for any extensive rework. Going to be putting in new tub as well. Suggestions? Thoughts? Thanks in advance.
