Who says that you have to turn up the water to have a better shower? Rua is a Kickstarter campaign that wants to deliver you a fuller shower and take up less water doing it.
Unlike traditional showerheads that are large circular hoses, Rua is uniquely designed as a geometric ring that can apparently deliver a wider shower with more even coverage across your body, according to the campaign page.
