For the eco conscious man (or one who finds himself bored with the business-as-usual atmosphere of the men’s room), designer Yeongwoo Kim’s Eco Urinal might be of interest. The concept is simple; the same urinal stand is used for both the peeing and the handwashing. The thinking is that the water you use to wash your hands above will also trickle down and rinse out the basin below, making the water of a flush unnecessary. 
It’s yet to be seen whether the design, which is an iF Concept Design 2010 winning entry, will go mainstream.
