One of my bedrooms at home opens into an open concept bathroom. No doors, vaulted ceilings, open.
I really don't get this.
I don't want to feel claustrophobic.

Those that prefer privacy and those that don't care.
If you're single or have a partner that you're comfortable with, open concept bathrooms feel luxurious. But if you need sanctity and salvation from the kids, I can get it.
Even if I'm alone in a hotel room, I'd prefer to contain the odor to the bathroom.
But even without talking about toilets, I don't like airy/drafty feelings when I'm wet, so I'd hate most of those designs, myself.
Making Privacy Work
Make sure to address the elephant in the room - privacy. Consider installing electrochromic glass panels that switch from clear to opaque. Or take inspiration from Japanese architecture with sliding wooden screens that double as art pieces.
