Lenny Bruce would have had such fun with this, but this just makes so much sense, a sink built on top of a urinal! And designer Yeongwoo Kim has made it look good, too. The theoretical sequence is that you use the urinal, then wash your hands and the washwater rinses the urinal, saving water. Since of course, everybody washes their hands after peeing, right?
The designer writes on his website:
To save water, Eco Urinal is designed to use the water that was used for washing hands to flush the urine. By this process, we don't have to use water twice after using the urinal.
Moreover, it reduces the establishment expenses by optimizing the materials. Upper space of this urinal is made with glass, and it helps to secure a clear view for users. It also promotes people to keep their sanitation because people need to wash their hands to flush the urine after use.
This in some ways makes more sense than a waterless toilet and probably saves as much water. Gray water harvesting never looked so good.
