Allure F-digital flexibility for your Grohe SPAÂ® convenient and discreet effortless and intuitive to use. Allure F-digital takes the faucet design in a new direction. A square base plate gives rise to the circular control mirroring the same design details that give Allure faucets their modern appeal. Simply turn the product on, twist the outer ring to increase water flow, and press the plus or minus to increase or decrease the temperature. To further enhance usability, an LED ring gives visual feedback on the water temperature. And for the bath and shower, the digital diverter lets you switch between water outlets with a single touch.
