The Moen spa shower uses a unique water delivery system to provide more pressure and double the water coverage of traditional showers, creating a blissful showering experience. Meticulously engineered for optimal warmth, rinsing, and body coverage, the shower creates the sensation of more water while actually using 45% less when compared to a standard Moen 2.5 GPM showerhead. This means each water drop works harder to get you clean, refreshed, and ready to take on the day.
