City villa floor plan 185m² - Please provide feedback!

Are these floor-to-ceiling windows?
I would plan the one next to the shower with a parapet. You are always standing naked there.

The shower seems narrow to me.

Yes, many have that problem with 2D.
There are minimum dimensions you need. For example, the space between the table edge and the wall. That means a little more is not a mistake. After that, you can draw and move things around.
Measure in your apartment. The cupboard that is now too small needs to be bigger. That also works in 2D.
How the room feels, of course, does not.

A bathroom with a bidet, we don't have that every day here. Is the flower column in the corner meant to serve as a shelf for the shower gel or does the bathroom planner limit themselves to stylish surfaces? Of course, this is just a serving suggestion, the floor-to-ceiling windows cannot all be serious.

The floor-to-ceiling windows are more than unnecessary in the bathroom. Even normal windows will always have to be slightly closed with something, since you have to pass by them when coming out of the shower, and you also get out of the bathtub right in front of the window.

I would probably swap the sink and the bathtub, then you would have natural light on the side of the washbasin.

And, show us your drawing attempts at furnishing, then we can give you more tips.

The shower is only 1.5 tiles wide, I suppose exactly 90 cm. That would be too narrow for me.

Take exact requirements with you on Wednesday. Not just food, but I need space for a freezer 100 x 60 cm, 10 m shelf, etc. Walk through your apartment with a tape measure. For example, the bedroom Exact measurements of the bed, distance bed to wall. Measure again, you need more than that. Mark it on your plan. Then you know Fits, one wall has to be longer, we still have some leeway there. Until later you are at a friend’s and he has a wardrobe you like or tomorrow the small dining area at your mother-in-law annoys you, ask if you may measure so you can estimate your plan Bare square meter specifications are not helpful

I also have floor-to-ceiling windows in my bathroom and the other rooms on the upper floor. Due to the fall protection, only the upper parts can be opened, the windows are divided in the middle and fixed glazed at the bottom. In the bathroom, the glazing of the lower part is an ornamental glass, which looks very good and is not transparent. Just as a note - in an earlier version of the bathroom floor plan, the toilet would have been there. Now the washbasin... but even there one might not want to provide a peep show for the neighbor...
