Designer Julia Treutiger has come up with an eco-friendly shower tap design that reminds you to conserve water.
Happy Tap features segmented joints that break apart providing a visual timer as they slowly snap back into place. This subtle mechanism reminds you to cut your shower short and stop wasting water.
