Felt tip signature, "Buckminster Fuller,” on an 8.25 x 10.25 book page featuring marked "Dymaxion Bathroom" and featuring drawings of a multistory dymaxion house. In fine condition.
Prefabricated and lightweight, the Dymaxion Bathroom was designed to be easy to install, sanitary, cost-effective, and easy on the environment. It broke down into five pieces and all of the necessary appliances and plumbing were built-in, including a sink, toilet, and combined tub/shower. The bathroom wouldn’t harbor mold or bacteria (and the mirror wouldn’t fog up), due to electric heating strips and a ventilation system designed to draw steam out through the under-sink vent. A shower required only one cup of water using Bucky’s 'Fog Gun' technique, by which a jet of compressed air mixed with a small amount of water to blast off dirt; unless someone was really filthy, no soap was needed. The waterless 'Packaging Toilet' separated urine and excrement, and shrink-wrapped the latter to be picked up for composting or fuel. The fact that it was waterless was a big deal—ordinary toilets use around 2,000 gallons of drinking water, per person, per year.
