MUTU / faucet


Everybody knows that turning off the water when it's not needed, is the simplest way to save water but how many people actually do that?
For example, when we’re washing hands, we often forget to turn off the water while we’re rubbing hands with soap. People may think it’s not a big deal because it’s very short time, but if the water still comes out while we’re cleaning, approximately 1.5 liter of water can be completely wasted.
MUTU is interactive faucet between water and soap. The lever goes up, water comes out and the soap case is closed. To get your soap, you should push down the lever, and then the lid of the case is going to be opened.
