Ideal for retrofit or renovation, the Retro-Fit Complete Shower System installs easily and quickly. Simply replace the existing shower arm and add the system components without altering any in-wall plumbing. Once installed, it’s easy to use; a quarter-turn of the diverter lever (located at the bottom of the shower bar) switches water flow from the showerhead to the hand shower or you can have both outlets on simultaneously. Grohe StarLight is a flawless, robust, long-lasting finish designed to be extremely resistant to dirt and scratches. It features advanced shower engines to deliver precise and consistent water distribution throughout any spray pattern for an unparalleled and custom showering experience. Speed clean anti-lime system: Removes limescale with a simple swipe of a finger to maintain a like-new performance. Switches between hand shower and shower head or dual function via a built-in diverter.
