The Hyphae Design Laboratory created this composting urinal, which was recently piloted in San Francisco’s Tenderloin district. Unlike the French model, it also includes a sink: after going pee, you press a foot pedal which siphons water out of an adjacent tank to wash your hands. The hand-washing water then flows into the urinal to “flush” it into a second tank, which is filled with special bio-filtration medium and planted with bamboo.

Unlike the Uritroittoir, the PPlanter comes with disposable funnels that adapt the urinal for use by women – the design offers slightly more privacy than the Paris model via a waist level partition that conceals your private parts.
