Why are you planning a guest bathroom with a shower when you don't have a guest room? This is a question for my understanding
In case two people want to shower at the same time... As you already mentioned: keyword puberty

Perhaps a door from the kitchen to the hallway could be installed. If I move the countertop to the window front...
QUOTE=linthe;53619] Stairs and hallway - I find the distance extremely small - you are basically heading straight to the wall. I find the entrance area very cramped - what if you want to say goodbye to or welcome a few people? - In contrast, the living room is huge. You really have huge children's rooms - I would seriously consider separating a toilet and making the shower a bit bigger - you would even have space for a children's bathroom - but it also causes additional costs. Four people sharing one bathroom becomes problematic at the latest from puberty. We have children's bathroom/bathroom adjacent and the toilet below - that saves quite a bit of money because of the wastewater piping. [/QUOTE]
Shower moved towards the outside + smaller guest toilet = larger entrance area with possibly a wardrobe.
Shuffle things upstairs again and possibly install a second bathroom and/or separate toilet.
Thanks for the feedbacks
