The KOHLER Parallel collection is the epitome of understated chic by combining circular shapes within the square design, the balanced versatility of this collection allows it to blend in or stand out depending on your surrounding decor. This single-function showerhead now brings an even more substantial water savings to your bathroom while delivering an uncompromised spray experience with Katalyst Plus technology. Katalyst Plus utilizes a 1.25 gpm flow rate, and by infusing 2.5 liters of air per minute, it maximizes every water drop to deliver a powerful, voluptuous spray that clings to the body with larger, fuller water drops than ever before.
