Repairing plasterboard 'honeycomb' stud wall before tiling

Whilst removing the tiles from my shower, a large section of the plasterboard has been damaged. The internal wall has the 'honeycomb' construction. I think I have a few options but not sure which is best.

1. Replace the whole plasterboard panel, which would create a bigger area of damage but I might have to anyway if I can't scrape the old tile adhesive off.
2. Cut out the section of damage and dot and dab new plasterboard straight onto the honeycomb.
3. Cut out the section of damage but take it wider to find the nearest stud, which is just where the wall changes changes angle to the right of the picture.
4. Replace the whole lot with aqua board to the nearest studs.

This was not water damage btw, just came away with the tiles. Above the damage is solid. It's 10 years old with no moisture damage so far.

Any help and suggestions will be appreciated.

At least the tiles were well stuck on there & the wall reasonably sound, usually what happens is the whole lot behind there disintegrates into a moldy, gooey mess. You will need to get all the adhesive off before you can re-tile so the easiest/quickest option is probably to replace the whole panel. Plasterboard of any sort is unsuitable for a wet area unless it’s tanked & Aquaboard is only moisture resistant plasterboard, it should still be tanked in a shower. I’d use Aquapanel (cement board) but you may have problems getting suitable fixing/bonding to the Paramount egg box inner stud (bloody crap IMO). If the adjacent walls are the same, your gong to have similar problems with those at some point & if you plan on re-tiling the whole shower, it may be better to strip out the paramount walls altogether & start again with something more suitable.

Do your homework on wall & tiling materials before deciding & re-tiling.

I'm in a similar position, and would be interested to know the method you chose and what the outcome was?

I know this thread is very old so I'm not expecting a reply but worth a shot.

I had the same, I fitted Kerdi board with tile adhesive and cavity fixings over the top of the paramount wall.
