I saw this on Low Impact Living. Although it seems kind of icky to me that you’re washing your hands with toilet water, I’ve gotta admit it’s a cool idea.

The hose is directly attached to the supply line, so it’s not water from the tank. When the toilet is flushed, the water that is normally used to refill the tank will come out of the faucet. This becomes grey water after washing hands, which is then used to fill the tank.

I still wouldn’t want to brush my teeth with it though.

Sink Positive sells for $89 and $109 for the deluxe.
