The four, stamped sheet metal or molded plastic sections are each light
enough to be carried by two workers. They'll fit up tight staircases and
through narrow doors, allowing retrofitting in existing structures. All
the appliances, pipes, and wires are built-in, limiting on-site construction
to mere hook-up.
With the sections bolted together, the interior has no germ-harboring nooks,
crannies, grout cracks or anything that can rot. Large-radius corners make
germicidal swabbing easy and complete. Downdraft ventilation draws fumes
and steam to the undersink vent. Both sink and (deep) bath-shower are arranged
to ease the care of children and seniors. The mirror doesn't steam up, the
sink doesn't splatter, and the toilet paper stays dry.
Dymaxion Bathrooms are to be equipped with "Fog Gun" hot water
vapor showers that use only a cup of water to clean hygienically without
soap. Remarking that "Nature had designed humans to separate urine
and excrement. Both are valuable chemistry, and should be collected for
further use," Bucky specified a waterless "Packaging Toilet"
that deftly shrink-wrapped the stuff for pickup for later composting. (Ordinary
toilets use approximately 2000 gallons of pure drinking water per year to
flush - and waste - one human's "exhaust" that, if dried out,
would scarcely fill two 5-gallon pails.)
