Why does the head have two sinks?
Presumably for double occupancy, with one toilet and one urinal. No time to wait for sink space during a red alert!
Those plans only show one toilet stall in the head.
I just took another look at the Sternbach (official) blueprints and they show a very different Deck 1, but still some similarities to those linked above. It does show a "lower" Deck 1 that the "ramp down" leads too.
