Abstract: A waterfall sink has a series of contours as elevationally spaced apart upper steps separated by vertically extending walls extending from an upper surface of to a bottom surface to form a partial sink bowl. The bottom surface directs fluid from the partial sink bowl off a side edge to then downwardly proceed to a drain below the bottom surface. Many embodiments have a channel extending into a side surface along the side which receives the fluid from the partial bowl. Some embodiments have side steps which coordinate with the upper steps to form a continuous partial perimeter. Water from a faucet directed into the partial bowl proceeds above the bottom surface and over the side edge downwardly like a waterfall.
