The Gerber 49-111-RB is a single-function showerhead, meaning it provides one type of water flow pattern. It has a flow rate of 2.0 gallons per minute (GPM), which determines how much water it dispenses per minute. This flow rate strikes a balance between water efficiency and a comfortable shower experience. The showerhead comes in an oil-rubbed bronze finish, adding a classic and elegant touch to your bathroom decor.
