I am kind of obsessed with bathrooms, and just built my own weird one with a sink in the hall and the toilet in a room of its own. (see Why am I building such a weird bathroom?). Now Metaform architects take it one step further in an apartment in Luxembourg, where they build the tub and a pair of sinks into the bed. This could be considered really efficient use of space, or it could be considered just weird.
I might copy those hanging mirrors. Terrible lighting though, spots behind your head like that. I am not quite sure how you would get into and out the tub; either climb over the end opposite the taps or go over the side from the bed, which does not seem wise if you want to keep the bedding dry.
It is always a good idea to put the toilet in its own room with ventilation. Making the room out of glass is, I suppose, a matter of taste. It is certainly more restrained than putting it in your living room.
Found on Contemporist, which is also bemused.
