The first recycling shower, operated by a hand pump, was patented in England in 1767 by the stove maker William Feetham.

In 1988, Francis R. Keeler patented a similar but smaller and more mobile version of the recycling shower for usage in motor homes, boats and airplanes.

Orbital Systems has had several high-profile investors, including Skype and Kazaa co-founder Niklas Zennström and Karl-Johan Persson, CEO of the fashion company H&M.
