Cover bathroom walls with drywall?!?

One more question. Is it sufficient if I simply lay the panels or does it have to be double? I would double-board the [Vorwand], but if I "plaster" the walls, that should be enough, right? Thanks

but if I just "plaster" the walls, that's enough, right?

Yes

Yes

Thank you

So, the whole project is slowly picking up speed ;) Next week the installer is coming to do the piping and set up his connections. After that, I can theoretically start with the drywall. Someone will also come to take a look at the ceiling in the next few days. I now have a question about the corners or the window niches. Knauf offers corner profiles made of gypsum board. To me, that looks like a proper solution, especially since not everything in the bathroom is going to be tiled. This way, at least I would have a neat edge that could, for example, be plastered. We have an external corner in the bathroom for which I am considering this. What do you think about it? Or is a normal edge protector like in the other picture sufficient? I am just a bit concerned that if, for example, only a thin layer of plaster is applied, the profile will show through. You would have to fill everything in first, right? How would you handle it in the niches? Thanks
