We encounter this frequently in certain Northwest Washington DC neighborhoods: the mini master bathroom. It's just big enough to do what you need to do -one at a time- and no more. This is the lay out that comes with the typical 40's built colonial. Three bedrooms up with one half of the second floor allocated to a front to back master bedroom. Located at the rear of the master is one closet --not large enough to store clothing for two. Next to the miniature closet is the infamous mini master bathroom. Neither is big enough. Most people find this irritating.
