Sink built into toilet saves water, grosses out
The Sinkpositive Sink is a sink built into the toilet tank lid so that after you flush, the sink starts running with water that would normally go straight into the tank. This way you waste less water and don't have to worry about walking over to a sink and turning a faucet on. Although washing your hands in your toilet just feels wrong. I don't care how clean it is, you might as well be asking me to eat my breakfast on a pile of feces.
