It’s looking up
Another blow for bathroom privacy. When will people be able to pee in peace?! We all know that, if you’re trying to make somewhere look larger and more inviting, then a mirror can create a feeling of space and light. Perfectly usual design trick.
But in a bathroom? On the ceiling? Something tells me that no-one actually sat down (on the toilet or otherwise) and thought this through. Because, as friendly as I am, I don’t want to look up when I’m on the toilet and see someone from the next stall waving back at me.
