An overly-extended shower not only wastes a large amount of clean water but also chronically damages one's skin. We designed a physical interface that encourages users to shorten their shower time and save more water. Our shower control is both a push-down switch and a timer. The spring-back mechanism automatically turns off the water after a shower reaches the 5-minute maximum. As the control nob moves back to its original position, the user can keep track of time. The nob is also a water temperature control. Our design can foster a more sustainable practice for the users and the environment.
