Bathroom planning, shower without bathtub

ok, I will try to move the washing machine upstairs (maybe separate it with a little wall or something. The shower from 168 is too small. I would have to install a door. I prefer to avoid that (because of cleaning effort). The shower needs to be approximately 180 x 90 (unless I am wrong) to work as an open shower without splash flooding.

Then I will do a bit of puzzling. I will keep the toilet separate (it might become a co-housing house or family house. I think a separate toilet is not bad in that case.

The bathroom cabinet has a sloping roof, then? Can you mark the 1.80m line? That naturally makes positioning a bit more difficult.

The floor plan is already built as indicated in the plan.

Even the non-load-bearing walls already? - where are the installations supposed to go (into chases - I see no drywall partitions set up)?

Unfortunately, this often happens accidentally on mobile that you rate with only one star...

I would even say the rating is completely useless because, based on my several years of experience at least, more accidental than intentional votes go into it.

maybe separate with a little mouse or something.

a co-housing house

What is that?

The shower must be approximately 180 x 90 [...] to function as an open shower without splash flooding.

A townhouse bathroom is not a wish concert.

Also the non-load-bearing walls too? - where are the installations supposed to go (in chases - I don't see any drywall partitions installed)?

The plan looks Dutch. They build a bit differently there and cables can sometimes be surface-mounted. By the way, it looks quite neat with copper. We don't have to export our sometimes quirky standards.

The shower must be approximately 180 x 90 (unless I am mistaken) to function as an open shower without spray flooding.

I am not sure if the statement I heard is correct. But several people told me that a shower should be at least 1.50 to remain open. And that is already the minimum size. Since we never reached that, I quickly discarded the idea, but maybe someone here can say something about it.

... how do you come to the conclusion of a sloping roof? can you please comment on that.

Otherwise, I see it like .. shower at the top of the plan and washbasin at the bottom of the plan, but of course with washing machine and dryer. You can wonderfully build something 70 cm deep so that a sliding door can be placed in front of the washing machine/dryer.
