Katalyst uses cutting-edge technology to intensify the flow of water for a showering experience that is completely indulgent. With a new nozzle pattern, internal waterway design and air-induction system this technology maximizes every water drop and creates a richer, more intense flow of water that heightens the shower's sensory experience. By infusing two liters of air per minute, Katalyst delivers a powerful, voluptuous spray that clings to the body with larger, fuller water drops. The showerhead integrates with the Forté faucet collection and resists hard water buildup while providing water flow of 2.5 gpm. Its Vibrant PVD color finish options resist scratches, tarnishing and corrosion.
