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.
I'd rather sleep in a shared room at a hostel and use a toilet in a stall in a communal bathroom than in a hotel room without a proper door on the bathroom.
Right?
My wife and I don't use the toilet in front of each other. Even when we lived in an apartment with only 1 bathroom. You gotta use the toilet while one is showering? You can hold it.
Even when I'm home alone and don't expect her to come home any time soon, I close the door. I just feel so exposed with the door open. Even when I lived alone, I'm pretty sure I would close the door.
I wouldn't be OK with going on trips (or sending people I manage on trips) where two people had to sleep in the same room, I wouldn't consider that acceptable...
This is why many newer hotels choose to sliding doors, which barely take up any space, or just remove doors entirely.
[0] For a door of r=3 feet, A door swings a minimum of 90 degrees, which takes 3.14 * 3*2 / 4 = 7.065 sq feet at a minimum to 14.1 sq feet to operate.
And also, when I travel with my kids, I still want to close the door.
