Floor plan design for a hillside house with 5 children's rooms

I currently do not consider any drain to be fixed. A privacy screen seems unnecessary here, and a sliding door unnecessary. A normal hinged door can actually be operated more quietly, and there is no lack of space for its swing area.

Door further towards the top of the plan. Bathtub centered on the bottom wall of the plan. Toilet on the left wall of the plan. Washbasin nicely at the window. Everything is still possible.
Or shower or toilet in the bottom right corner...

With toilets next to the washbasin or next to the window, it has the advantage that you can also get ready while sitting down.

I can vividly imagine Yvonne styling her hair on the toilet...

Nowadays there are toilet seats that you just have to tap, then they close by themselves. I once gave my husband this instruction – works! [emoji2]

It might be a bit indiscreet, but personally, I prefer it open, especially on unfamiliar toilets. That spares you an almost nightmarish "surprise" if the toilet isn’t clean enough. I'm very allergic to that.

A normal hinged door can usually be operated more quietly, and there is no lack of space for its swing radius.

Here it was about the option to pull the door maximally towards the bottom of the plan. Then it might hit the bedroom door, or the two doors would get in each other’s way. But something apparently blocks the space anyway, whatever that may be. Otherwise, you’re of course right. Laying such a pipe should be something a man can do.

but personally I prefer it open, especially with public toilets

Tastes differ so much. Lid open, no, that comes right after forgetting to flush for me :-(

I currently don't consider any drain to be immovable. A privacy wall seems unnecessary here, and a sliding door is superfluous. A normal hinged door can even be operated more quietly, and there is no shortage of space for its swing area.

Our documents state very clearly that after submitting the building application, the sanitary fixtures may no longer be moved [emoji85]. I think they'll jump up and down if I come up with that now [emoji85][emoji23]. But actually, the sink is really badly positioned there now [emoji848]

By the way, I am also part of the lid-open faction to prevent unpleasant surprises [emoji23]
