WoW Shower

The WoW shower is a curious device that recirculates warm water pooled in your tub back through the showerhead — thus saving water. You can have a longer shower under the waterfall-like stream (is this the "WoW" factor?). It seems that the pooled water is filtered and refreshed with new water. At the end of your shower, you do a final rinse by turning a diverter valve. It requires at least 35 psi of water pressure for operation, and $99 to buy. :: WoW Shower
