We bought a bank-owned 1980s house that needs improvements. In the master bathroom, the tub and toilet are separated by a door from the sink and counters. In the very small space that houses the tub, shower and toilet, someone has taken very hot showers and the steam has melted the wallpaper off the walls. How can we fix this? We need to cover the walls with something. I would really like to paint them, but all the sticky residue from the previous wallpaper is a mess.
