At the 2011 International Builders' Show, Kohler introduced a number of new products to meet the consumer demand for increased functionality, simplified aesthetics, and water conservation. Some of the product lines featured this year included Karbon, Loure, and Stance faucet collections. These collections are sleek and stylish and can reduce the water consumption by 30% without sacrificing performance. This year Kohler also featured a digital thermostatic showering system. The DTV II uses a one-piece interface design that provides convenient control of the menu-based navigation system, allowing the user to program the shower's water temperature, spray settings, and lighting.
