Finalization of floor plan bungalow 130m² for 4 persons

I didn't say that.

*uff* I don't think a small mini bathroom is a bad idea either, but for that, I think you really need to gather the exact measurements and plan precisely.

but what good is it to you if it is feasible but you don't want something like that at all??? you always end up falling flat on your face! you can do something like that out of necessity (bestand). but you are planning a damn new build, man! that is a no-go. you can do something like that without a shower, but with one, that just doesn't work at all.

then please include yourself in my floor plan planning. The guest bathroom will be a narrow bathroom anyway. See posting #25 as an alternative. (Narrow bathroom plan below under the utility room)

The idea was to equip the guest bathroom with a window but to save as much space as possible.

Oh dear, this is a mess and not a house. Have you ever thought about an apartment? Maybe better.

Wow, I still have more space in our Glamping Pot

The idea was to equip the guest bathroom with a window but keep it as space-saving as possible.

Move the kitchen half a meter away and attach it to the guest WC. The utility room moves along as well.
