Hello all. We are going to tile our shower and have discovered a challenge during demo today. Our house is brick construction, built in the thirties. The shower surface was a later period shower panel that was glued to a layer of plaster (the original shower surface looked like something painted on the plaster?). The plaster was over top a sheetrock, which we have removed down to studs. The problem is the brick side outside wall. There it appears to just be a thin layer of plaster over a thick layer of cement over a grooved metal something on top of the brick, no studs that we can see as of yet. We want to have the cement board at the same level as the rest of the wall. Is it possible to just knock away the thin layer of smooth plaster, skim coat something over and then just tile over that?
