House Extension Split-Level - The First Design

Bathroom does not work barrier-free like this, unless you simply mean without thresholds.
Google zero barrier floor plan

The shower is about 20 cm too narrow. Is it possible to roll a wheelchair forwards in and backwards out again? Why must one be able to rotate 360° with a wheelchair in the shower?

There are about 10 cm missing in the turning radius in the room.
The wardrobe would of course be out of place! The sink might need to be adjusted if necessary.

I also do not want to apply for any funding for this, as there is initially no reason for a wheelchair.
... but you never know what will come! Therefore also the reserved lift shaft, which is intended to compensate for the disadvantages of the split-level if needed.


Does anyone have practical experience or tips on what is actually important?

What are they supposed to be missing there?

Can you roll in forwards and out backwards with a wheelchair? Why must you be able to turn 360° in the shower with a wheelchair?

a) why should you do that? b) no, you don't have to. A care patient is at most maneuvered under the shower with a commode chair; a wheelchair is not used for that. You don't shower with a wheelchair. However, a caregiver can certainly require no less space than would fit into the turning radius.
