One more wall question
Ok, last wall in my bathroom. I need to decide what to do here. The tub flange will nail along the exposed stud in the corner which is highlighted. What I need to know is this

Should I try to keep the existing plaster/drywall wall that is there and try to mend the corner somehow where it is highlighted in yellow?

Or cut back the wall a bit and seam it w/ greenboard/purpleboard/backer or whatever I decide i'm using, where I have highlighted in blue?

I would just fix it at the corner. If you tear it back to a stud the joint is likely to be more visable than at the corner.

Anything in particular I should use to repair it at the corner?

DO NOT CUT it back. Make your corner where it is in your Picture.

Attach your tub surround first.

Leave that plaster corner exactly where it is. Put your MR board up above the shower area, Then, Put a thin sliver of Moisture resistant SR over the tub flange along the other side near the corner.
Next, add a piece of corner bead over that outside corner (covering both sides)
Attach the side with plaster on it with longer screws to go thru the plaster layers into the corner outside stud.
If you are worried about not being able to hit wood on the tub side because the plaster comes out too much in thickness:
Use what is called 'no coat'. It is re-inforced plastic shaped into an outside corner with paper edges. It is applied with compound, not nails or screws. It is wider to cover the outside corner.
Tape it nicely. Use a small putty knife for the side where the tub flange is. After sanding, add a nice bead of colored silicone where the drywall meets the shower edges. The caulking ties it all in nicely.

See, this is why I ask these questions... Thanks again guys. Very helpful.

Ok, I think I may end up going w/ the no coat. It may be better considering the plaster wall is a little bit further away from the outside corner than the corner stud. Plus, my father just got done using some no coat on a drywall job and he won't shut up about how much he like it, lol.

oH, I get it. Thanks.
