Hello, We recently purchased a home and have tackled pretty much all the other problems in the house except for the walls in the small bathroom. The room itself is about 5x6. One wall is a tub/shower, and each of the adjoining walls have a small strip of "Wall" and then a door. So basically it looks like this: [ ] The little strip of wall between the tub and the door on each side is peeling and is soft, probably rotten. How do I replace this drywall? It's probably a foot wide, the problem section is about two feet tall. There are two inch baseboards at the bottom. MY main questions are: Do i need to take off the door frame, do i need to take off the base boards, do i need to do anything to find out if there's drywall rotting behind the tub as well, and even if i cut out a piece of replacement and bolt it in, what would i tape it to? Thanks.
