Main bathroom (10 sqm) with open shower, any ideas?

Yes, that would be one option, but is 50cm of space in front of the toilet better than 50-55cm at the entrance to the shower? Unfortunately, neither is optimal.

There would be more space on the right side.

You will have to make a compromise one way or another.

I would choose the compromise that annoys me the least over the next 30 years: Reach into your wallet and pull out the bills for the corner bathtub.

If necessary, forego this sink if you can retrofit it. I would also tend towards the corner version.

More than €1,600.00?

Our builder already wants 1,600 EUR for the 180x80cm Kaldewei Duo Classic. ...

By the way, the 170x75cm is a Kaldewei Saniform Plus.

There would be more space on the right side.

You will have to make a compromise, willingly or unwillingly.

... I don’t even want to know what utopian price we would get for a corner bathtub.

Otherwise; "you only build once"... "it’s for the long term," you often tell yourself when building (you know that yourselves ), but at some point, it just doesn’t work anymore.

But you also won't get the otherwise necessary additional glass wall for 200 euros.

You will have to make a compromise, whether you like it or not.

I stand by that.

I need a glass wall anyway, even with your corner bathtub solution.

A glass wall at the door, yes. In your last two drafts, you each "built in" an additional one on the side of the shower at the bottom of the plan.
