ᐅ Washbasin: Pre-wall installation or relocating connections within the wall

Dear forum members,

For our new build, we are considering whether or not to install a stud wall in front of the washbasins.

The plumbing company says that both the supply and drain pipes can be installed inside the wall (in the ground floor in a Poroton wall and upstairs in a drywall partition). I think it’s a good idea on the ground floor since we don’t have much space in the guest bathroom anyway. Upstairs, I am wondering whether

A) you might hear water running in the adjoining room through the pipes in the wall if they are not properly sound-insulated,
B) the stud wall might be needed anyway for placing items. Otherwise, you would either need a very wide vanity unit or an additional shelf or mirror cabinet above the basin.

What do you think is better?

Thanks in advance.

From a design perspective:

• For smooth walls with in-wall installation: use a slim installation layer (soundproofing) or integrate into aerated concrete walls/drywall. (also acceptable)
• For a desired step or recess in the wall: use a pre-wall structure – it doesn’t need to extend from wall to wall to look good.
• For smooth walls with exposed piping as a design element: lay copper pipes openly.

I have the same consideration. In the guest bathroom, I will probably omit the pre-wall installation around the sink area. However, in the attic, I find it extremely practical.

Have you lost track of your individual topics, or why are you asking about this sub-subaspect separately here? We are already right in the middle of your bathroom at: https://www.hausbau-forum.de/threads/vorwand-im-Bad-og-direkt-neben-Fenster.30661/.

I guess both options will look good. Since I already have a vertical pipe shaft in the corner of the bathroom where the sink will go, I could incorporate it and extend it as a pre-wall. It would probably also look nice if the sink is mounted directly on the wall. In that case, people would likely put a lot more items on the washbasin shelf. I’m still undecided.

Yes, practical indeed, but it leaves a lot exposed, which is of course a matter of personal taste. If you don’t use a stud wall, you could also install a medicine cabinet, but I’m not a big fan of those either, as they often stick out quite a bit and you have to open the doors while standing to take something out. How deep are you planning to make the stud wall in the attic? I was thinking around 20 cm (8 inches).
