DTV+ is Kohler's most advanced showering system, bringing together two elements – water and steam – to give you a true showering experience. Every element of your experience is completely customizable to your needs and is controlled by this simple touch-screen interface. The DTV+ system, at a minimum, requires one interface, a K-99694 mounting bracket, and the K-99695 system controller. Beyond that, you design your dream shower by selecting the components you like; rainheads, body sprays, steam, or spa-like hydrotherapy.
