Bathrooms.
I designed two for a three bedroom two story Berkeley brown shangle were my ex-wife and qusi-trophy husband now reside. The upstairs one features hand painted Italian tile for the floor and white with a nice border for the chest high walls. The whole combo is sink, tolite, and wall shower. I designed it for the trip back from cycling, running, or morning exercise, to get ready for work in the fastest time possible. It is directly off the master bedroom and next to the small kids room, for night pee somnolent children under twelve. It worked well for somebody else's family.
There is a sociology of bathrooms. The rich need lavish bathrooms as accoutrements to their boundless narcissism---not that I am unfamiliar with the concept. Beyond that, I prefer something more organic with bathtub toys, and dirty cloths to stumble through, or homey style, unflushed by forgetfulness. Of course there are limits, but am afraid I've tested those limits and gone beyond them, ... a comfortable place to shit with something interesting to watch and a window to blow out the place. There are French Impressionists pleasures less defined like plants and light.
