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.
