re: "where the toilet is"
Have a look in any architectural magazine -- the only time you'll see a toilet is in the advertisements for manufacturers of the item itself. There seems to be an unwritten taboo about depicting the WC, even in articles specifically about bathrooms! (Must make it tough for the photog to get the camera angles just right...)
So it stands -- if not to reason, then to custom -- that it'd be left out of the Orion display shots.
Also possible: it's right there in the cutaway view, and we don't recognize it.
