temp grout seal for doomed bath
Hi. I have an old hall bath with a standard 1963 shower/tub, which is slated for remodel to the studs in the next few months. Water was getting behind the tile, through the old grout, so I duct taped shower curtains to the wall, so the wall dried out some, and the the tile didn't fall off. Even with three showers a day, it has held together so far. But my elderly blind mother-in-law is coming for Thanksgiving, and she can't deal with the shower curtains.
Can I waterproof the tile with sealant somehow, just to get it past this visit? I'm tempted to try to spray paint the whole thing, and reinforce spots with more duct tape.
Plus, does anybody know if there are temporary grab bars?
