   Jim,

   If you're replacing the tile in a shower stall, which is no small task, why not make sure the underlying substrate is not water damaged? The rusted corner bead is a pretty good clue that something is going on.

   Yes, you should replace the metal corner, and no, you can't do it without trashing the other side of the corner.

   Your last question is a little confusing. If you mean that you have a joint on the same wall plane where concrete board ends and drywall begins, then yes, spanning that seam with the last tile is the correct thing to do. Make sure you tape the joint with mesh tape, not paper. If that's not what you meant, disregard what I said.

   Thanks for the help. The drywall under the tile was wet and had mildewed in a couple places, so I tore it all down to the studs. The corner I was worried about is right next to the shower, and is also close to the toilet, so it sees a lot of humidity. The drywall right at the corner seems to be ok, though.

   The original tile was set on regular drywall in mastic, with studs spaced at 24" in places (non-load bearing walls). I guess I can't complain - it lasted 20 years. But I will add some studs to beef it up.

   You nailed my last question. I didn't know if there was a better way to handle the transition from backer board to drywall.

   Thanks for the help!

   I'm replacing the tile in a shower stall. The tile runs right up to an outside corner on one side. The metal corner shows just a little rust through the paint, in a couple small areas.

   Should I replace the metal corner? If so, can I remove the corner without trashing the wallboard on the side of the corner away from the shower?

   I have been leaving the backerboard a little short, and extending the tiles over the seam (1/2 tile past the seam). Is this the right thing to do?

   Thanks for the help!

   Jim,
   I sometimes prime a metal outside corner with one of the stain killing primers that comes in a can prior to mudwork. I haven't gone back to check on any of my installs to see if it helps, don't think it could hurt for all of five seconds to take a pass at the corner and hardly use more than a whiff of the can. Sometimes hit the corner again with the primer after sanding as this will bare the metal on the very outside of the corner. High humidity locations seem to bring a little rust stain through on these corners if they are metal, you could go to a plastic corner and get around the rust. Like you said, it took a long time for the original work to show deficiencies in spite of it not being anywhere near to the current practice. I am amazed at how long some of those old shower cubicles last just being regular rock down to the pan.
