That bathroom layout has become extremely common in normal hotels in parts of Asia and the Middle East.

But what's the logic? I have never seen it but it doesn't sound good even aesthetically (which is usually the justification for all kinds of violations of common sense). So what are they thinking?

A number of hotels that were built with this lack of privacy (including one I love - but its been fixed there though - more subtle worse as you could see in from the stairs) were all designed by the same architect who is said to have had a kink about looking into toilets.

Maybe he started it, and as his hotels are (otherwise) lovely it made it part of a cool aesthetic and was therefore copied?

It also sounds like a plumbing nightmare to build.

Where is Asia? I travel there often for work and have never come across such a layout

I get the joke on OP's typo for is/in, but even then you answered "what" instead of OP's "where".

It’s miscommunication all the way down

I live in Asia, I've only seen in love hotels.
