DTV+ is Kohler's most advanced showering system, bringing together four elements - water, steam, lighting, and music to give you a true multi-sensory 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, from rainheads, body sprays, and spa-like hydrotherapy to music speakers, steam, and chromatherapy.
