Our floor plan. Suggestions for improvement, tips?

Hello everyone,

we have a sampling appointment in a few days and still haven't agreed on how to design our bathroom, for example, where to put the bathtub? Furthermore, we are leaving out the side window in the living room. Do you experienced users notice anything else? In the guest room (ground floor), the window will be adjusted so that you can also go out onto the terrace. We are three people in the household and are planning for another child.

Thanks to you all.
Have a nice Sunday.

Give up the pantry and add it to the kitchen - it becomes very cramped that way. Food can also be stored in kitchen cabinets - even boxes.

Door to [Technikraum] opening inward

Just as a tip and has nothing to do with the floor plan. I would change the position of the outdoor faucet and place it either in the exterior wall of the [WC] or the [Hauswirtschaftsraum]. Running the wastewater pipe once across under the house would definitely not be my choice; I would always lay the sewage on the shortest route outside, even if it is a bit longer outside. You never get access again under the house, or am I misreading this in the plans?

What does the outdoor water tap have to do with wastewater?

I find the idea quite interesting to dispose of wastewater via the outdoor water tap.
