Lloyd Alter, the editor of Treehugger, wrote this insightful feature about the history and design of the typical household bathroom. It traces the origins of the modern plumbing system that weaves through our cities, and explains why the many design defects of the current standard bathroom setup. For one, ergonomics is poor--toilets are too tall for a comfortable squat--and sinks are too low. But more importantly, the modern bathroom is extremely wasteful. Alter suggests alternatives like composting systems that split off greywater from blackwater, and a shower setup that only dispenses water when you need it. Of course, this doesn't take into consideration the other activities that currently happen in many bathrooms; the water closet is now a place where many people get their work done. Smartphones and tablets in the bathroom are still gross, by the way.
