I would like to install a shower above an existing bath that has about 4' of tile work above the bath. The upper edge of the tile is bull nose. The tub and tile are in very good shape and I do not want to remove them. The walls above the tile appear to be plaster as are all the other walls in the house. It could possibly have a cover of sheetrock over it but I do not think this is the case. The upper walls are in very good shape for old plaster.
If I install some type of waterproof paneling above tile my concerns are 1) it would not look nice, 2) there would always be a problem of water getting into the seam where the bull nose tile met with the paneling, and 3) will moisture/condensation build up under paneling that is glued to the plaster.
I have attached a picture of the tub, tile and wall. Any advice on how this could best be accomplished is appreciated.
