Inspired by the elegance of early 1900s American design, this Bancroft multifunction showerhead provides three distinct sprays – full coverage, pulsating massage, or silk spray – all enhanced with Katalyst technology for a completely indulgent showering 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. Advanced spray engine provides three experiences: full coverage, pulsating massage and silk spray. Full coverage spray produces an encompassing spray for everyday use and utilizes Katalyst® air induction to create large, full drops. Pulsating massage spray targets sore muscles to ease away aches and pains. Silk spray releases a dense, luxurious spray ideal for rinsing. Thumb tab allows for a smooth transition between sprays. MasterClean™ spray nozzles prohibit mineral buildup for easy cleaning. 2.5 gpm (gallons per minute) flow rate. Shower arm and flange not included. Coordinates with Bancroft® and Devonshire® faucets and accessories. 1/2-inch - 14 NPT connection. KOHLER finishes resist corrosion and tarnishing.
