Floor plan design of a 145 sqm single-family house on a slope

Sorry, but I wouldn't continue planning with an indoor toilet at all. The reason is not the missing window, but rather the messed-up drain pipe that you can't access later on.

I find it annoying that the laundry is hung up in our bedroom and that the dirty laundry piles are located in front of the washing machine (and thus in the middle of the bathroom) after sorting the laundry. Hence the idea of the utility room.

In the small utility room, it only works with a dryer. Of course, that's an option. I prefer to hang my laundry outside if possible.

I don't really like the shower in the guest toilet – the guest toilet is also for all guests who do not stay overnight. I want to keep it tidy and always clean the shower just so the overnight guests have their own shower, I don't necessarily think that's necessary.

Yes, my guests constantly complain about the disgusting shower when they have to use the toilet.... If you have to save money and can’t afford a second shower, that’s okay. But talking such nonsense – count me out. Good luck.

Katja, notice something. You are being rude again just because no one agrees with you.

just because someone doesn't agree with you.

Just as much nonsense. It would be terrible if everyone agreed with me. I just have an allergy to far-fetched excuses instead of simply saying, "I don't like it" or "Out of money." Or are you seriously trying to tell me that the guest gets more excited about a windowless toilet than about a shower room with a window, just because there might be a soap bar lying across? Or what kind of guests are those? Do they poop in the shower? Or maybe the family? Whatever, I can't understand it and therefore I'm not the right advisor anyway – so get out of here.

do you define what excuses and what opinions are? If he doesn't like the shower in the bathroom then that's just how it is. Then quickly a whiny "I'm out" and an ironic "good luck" afterwards... not everyone has to be preached to all the time here.

slow down a bit. A great way to react to something you don't like is simply to not write/comment anything.
