ᐅ Installing drywall on bathroom walls?!?

Good morning everyone,
we have created an opening in the basement from a small WC to the room where the oil tanks used to be (we switched to a gas heating system). The old bathroom was quite small, so we made the opening to enlarge the space.
We have already removed tiles from some walls and now the walls need to be plastered somehow. Would you recommend getting them properly plastered, or could drywall be a suitable alternative? In the area where the new shower will be installed (where the waste pipe comes down from above), we will install a drywall partition anyway because I want to conceal the pipe there. I was advised against rerouting the pipe into the external wall.
What are your thoughts on this? The advantage of drywall is that most of it could be done as a DIY project. However, the ceiling definitely needs to be plastered. The rooms are already quite low in height, and I don’t want to lose any more space by suspending the ceiling.
Is it feasible to use drywall here, or would you recommend having it properly plastered instead?

One more question. Is it enough to just install the boards once, or do they have to be installed twice? I would double-layer the stud wall, but if I plaster the walls, a single layer should be sufficient, right? Thanks.

So, the whole project is slowly gaining momentum 😉

Next week, the plumber will come to install the piping and make the connections. After that, I can theoretically start with the drywall work. Someone will also come to check the ceiling in the next few days.

I have a question regarding the corners and window reveals. Knauf offers corner profiles made of drywall. This seems like a solid solution to me, especially since not all areas in the bathroom will be tiled. At least this way, I would have a clean edge that could be plastered, for example. We have an external corner in the bathroom where I am considering this. What do you think? Or would a standard edge protection like in the other picture be sufficient? I am a bit concerned that if only a thin layer of plaster is applied, the profile might show through. Wouldn’t you have to fill everything in first?

How would you handle the niches? Thanks
