The Speakman Reaction 1.5 GPM Single Function Shower Head is scientifically engineered to not only function with low pressure but flourish with it. Our team of engineers developed a single-function spray setting that concentrates and optimizes water pressure, creating an exceptionally high-pressure shower head for low-pressure installations. From the moment water enters through the fixture, a turbine-powered engine infuses energy and velocity into each and every spray. The result is a powerful, pulsating experience that performs brilliantly with low pressure. Features a transparent frame and a WaterSense Certified 1.5 GPM flow rate.
