The Envi Eco-Performance Rainshower showerhead from Moen features a self-pressurizing system that increases the force and flow of water delivery, and offers a flow rate of 2.0 gallons per minute (gpm), which is 20% less than the industry standard of 2.5 gpm. For a more powerful shower, the flow can be concentrated into 30 nozzles for a revitalizing rinse; whereas for a softer shower, the flow can be expanded to as many as 100 nozzles, delivering a rain drenching experience.
