The Grohe Grohtherm Smart Control Triple Volume Control Trim in Moon White allows for simultaneous control of up to 4 shower outlets, offering complete customization of your showering experience. You can connect multiple water sources like a head shower, hand shower, or side shower, and even a bath filler. To achieve the 4-outlet functionality, this trim must be paired with the Grohe Grohtherm Smart Control Thermostat 29118000. The trim features Grohe Easylogic markings, allowing you to customize the button symbols to match your shower outlets. This product is the control trim only; the Grohe Rapido Smart Box 35604000 is required and sold separately. Key features include 3 outlets and controls for various showering options, a metal wall escutcheon with GROHE QuickFix for concealed installation, a durable GROHE StarLight Moon White finish, SmartControl push-and-turn operation for ON-OFF and volume control, and exchangeable symbols. It also boasts scratch-resistant and easy-to-maintain surfaces, anti-scalding technology, and water-saving features. This product comes with a 5-year manufacturer's warranty.
