You mean apart from those toilet cubicles you get in the US where the door is only about three foot tall. I hate those, I run screaming when I come across one and save myself til later...

...and even when you find a cubicle with a decent height door it is designed in such a way that there is a quarter inch gap on both sides of the door for the world to look at you though.

There are many of lousy public loos in the UK, but at least the doors hide you from the rest of the world.
