Designer Yeongwoo Kim has created an “Eco-Urinal”.

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.

Isn’t that the same thing as if you just peed into the sink and then washed your hands?
