Hi - we've got bad moisture in our shower/tub surround walls we fear. Mold keeps growing seemingly from the inside out on the grout lines and we've now got at least one tile that's bulging out. We need to redo the whole surround but are still saving up for the tile, plumbing, etc. I was wondering if we could do the demo work now to get all the mold out of the walls and stop rot from getting worse and then line the shower surround with shower curtains or plastic sheeting and use it like that for a few months? I'd make sure the sheets are overlapping each other. Oh, and I forgot to mention that this is our only shower. We live in Seattle so I also have concerns about condensation since it's about 40 degrees outside until May/June. Any advice would be much appreciated! Thanks!
