Parent bathroom + children's bathroom arrangements

And what about the washing machine and dryer? Are they supposed to go in there too? Please provide info... we're already on page 5 and a half...

That is a good idea to redistribute the sqm a bit or to work with niches!

Yes, gladly! Do you have an idea?

One could say it roughly like this.... the lower picture shows the bathroom from a hotel room where I took a shower and hardly anything in the area got wet. This was because the shower fixture was installed at an angle.
The plumber feels sick when he has to install the drain pipes.
Although.... maybe it’s not that complicated after all.
Don’t get too hung up on walk-in showers. For an ideal of 1.80/2.00 meters, the room has to fit. Better 1.60, around the corner, and a bit more appealing.

One can also use slants deliberately, even if one does not like them

Thank you for the ideas. I hadn't even considered slanted surfaces yet.

If I were to do without a wardrobe in the dressing room and then move the door from the dressing room to the master bathroom 50cm further down: would that gain anything? Because I would be willing to do that.
