I want to replace Bathroom drywall

I have been doing drywall for over 28 years and I have found it best to remove the bull nose and replace the drywall with wonder board (cement board) and tape it and tape it with nylon tape and then skim it out to prevent moisture from destroying your patch

I would expect that a professional would likely do just as Homer said. In the end there is the lowest chance of anything going wrong after he leaves.

In my opinion, having also repaired more drywall than I care to think of, I would make patches for the holes, use paper seam tape where needed, and not disturb the tile. If you move any of the tile there is a great chance that you won't get it back in the same spot or you may loosen adjacent tiles. Not worth the risk.

Working carefully around the tile I believe that I could blend the repair so you'd never know I made a patch. This space should have been done with green board but cement board is overkill. Again, this is not necessarily the right approach. It is what I would do.

The more I look at your photos the more I want to ask if I can come over and do it. Looks challenging and no one will believe how it looked when they see the end result

I don't think he plans on taking out the tile. Yes you'll get a better transition removing the bullnose but you then run the risk of breaking a bullnose that you may not be able to replace. Your call. Definitely a better job if your able to remove the bullnose. You could take a vibrating saw and cut right even with the tile without damaging the tile but you'll never be able to tape the joint. You could run a bead of grout caulk the same color as the tile grout around the perimeter of the tile.

Maybe check to see if tile is available just in case then make the call. I've been doing this since the middle 70's and to be honest it could go either way. Really depends on the availability of replacement bullnose because breaking a piece of bullnose is probable. Just regular or light weight sheet rock is fine for the new board. You could go with the mold resistant green board but at the end of the day if it gets wet it's ruined green or not. Good luck

Christopher,

I read your problem with your bathroom walls, I would like to suggest a bit of extra information, how to eliminate the join next to your tiles First cut the d/wall board behind the tiles at a 45 degree angle behind the tiles, then measure the d/wall sheet that you are using to butt up to the tiles ,10mm [3/8th ] longer than the size of the length required. This allows for the end of d/wall to be cut at an angle of 45 degrees to match the tile cut When the sheet is in position the face of the d/wall will be flush or level with the back of the tile. Hope this helps you with your project

After looking this over and understanding that you're not a pro at this, I suggest that you cut away the wall board from the bottom of the medium size hole horizontally over to the middle of the stud at the outlet. Then up to the bottom of the larger hole following the center of the mentioned stud. Then jog over to the larger hole.

Next cut (up) to the bottom of the larger hole on the "tile side" staying in line with the existing smaller hole. Don't disturb any more of the d/w near the tile.

Remove the larger piece.

Replace with regular d/w--since that's what's all around it--I don't know if you're covering the larger hole, but if so make it all one piece. Make a cardboard or paper or roofing felt template if needed. You will need BACKING for the drywall all around or risk a crack later. (Actually there is always a risk of a crack, but try to minimize it.) Attach the new and the existing drywall to this backing and/or existing studs.

Now for what is left near the tile you have a number of options. I think I would use a plaster patch or "Fix-All". Just be sure to finish it a bit lower than what you want the final finish to be because is not easy to sand. Then, tape and finish all the joints and this patched area with as many coats as you need to get good results. It isn't done with only one coat. Just be patient. Good luck with deciding on whose advice you follow. All will work.
