DTV+™ is Kohler® 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 (sold separately). 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.
