Looks good at first glance. However, it is too narrow. How wide is the shower and the passage to the sink, bathtub? Do the bathtub and sink have the actual size as you are buying them?
No idea, to be honest. This is just a concept for now. In my opinion, I am researching how much distance there should be between the washbasin and the tub. We are flexible with the sanitary objects.
You are planning a new house, so why not a practical and beautiful kitchen? This is just an overblown kitchen. A few pages back, a user showed a kitchen that is practical, modern, extravagant, and really only works if you plan XXL. With the space you have, many things are possible that wouldn't work with 160 sqm. Use it.
