Kohler's bath and kitchen fixtures are available in American hardware and home improvement stores and from Kohler Kitchen and Bath distributors. Kohler still makes traditional cast iron bathtubs, one of the few United States manufacturers to do so. Besides residential products, Kohler manufactures a commercial line of bathroom fixtures. The company also does artistic custom work, such as hand-painted sinks and toilets. In 2015 Kohler was named by "Builder" magazine as the "most used" and "best quality" in the "Bath Accessories" category as well as the top spot for "brand familiarity", "most used" and "quality rating" in the "Bath Fixtures" and "Whirlpool Baths" categories.
