Mea culpa, not before I posted. Even the business class heads on British Airways aren’t anything like that. Then try one of the first class heads on a United 737 on a domestic flight. That level of relative “poverty” is my frame of reference.
I flew EVA Royal Laurel class last year, they didn’t have anything as opulent as above, but their lavatory was about 2.5 times as large as a US first class head. But still, that is just nasty.
