An ADA-compliant sink is supplied with a human powered foot or hand pump connected to a freshwater supply tank. The greywater from the sink, along with soap residue, flushes and cleans the urinal, keeping odor to a minimum.
The greywater, soap and urine (blackwater) from the ADA-compliant urinal are funneled to a sealed storage tank. The combined water is then pumped into an adjacent planter that houses bamboo plants set in a lightweight mixture of soil and recycled styrofoam coated in pectin. The water from the urinal and sink is evapotranspired by the bamboo and released into the air as distilled, purified water. The bamboo harnesses the incredible amount of nitrogen and phosphorus found in the urine and uses it to produce more bamboo. With high traffic urinals additional planters can be added to the system.

For the first time, HORIZONTAL SHOWER permits showering using the AMBIANCE TUNING TECHNIQUE while reclining. The application combines six WATER BARS recessed into a broad shower field above a reclining space, along with an eTOOL as the main operating element. Just as with VERTICAL SHOWER, with HORIZONTAL SHOWER the user can also choose from among a variety of pre-programmed choreographies, offering a range of settings for water temperature, intensity and quantity.
