Ideas for the floor plan and possibly some tips?

... The toilet you planned with a depth of 70 cm is quite a beast – with a shorter (normal) toilet you can also gain some space. ...

However, a normal toilet also has an installation layer, so you’re still at about 70 cm.
Now take a look at the sink: with 25 cm depth you can’t wash your hands properly, let alone brush your teeth when you’re older (as Heiko mentioned). Installing an emergency toilet is not a solution :rolleyes:
Why don’t you plan a floor-to-ceiling one, i.e. an invisible one, with only a drain in the floor?
That’s enough for showering once a year :)
With a shower niche you also have to change the kitchen at the same time, another drawback.

Everything that is in constant use should work – including turning around three times ;)

Oh dear, I’m totally confused now. What is a "bodentiefe"? You mean that you shower in the middle of the WC?

A walk-in shower means that you have a slope and a drain in the tiled floor.
So no shower tray is installed anymore.
This is not like in some caravans or motorhomes, where the WC can actually be in the shower area.

Good morning,

so, the roof has a knee wall height of 1m and a pitch of 40 degrees. Are the data sufficient?

Hello Heiko,

40° roof pitch is already not bad, that way you gain height quickly.

With a knee wall height of "only" 1 m, I really have some concerns regarding your bathroom. Sit down with the architect again, he should still have one or two ideas...

Regards,

Buy some wooden slats at the hardware store and screw them together so that you simulate a knee wall height of 1m and a slope of 40 degrees. Might help with the decision.
