Abstract: The present invention provides methods for adding a polymer form to a fixture such as a bathtub, shower stall, sink, or toilet, and those articles. The polymer form comprises a rigid foam and a topcoat. The polymer form, in some embodiments, imparts improved performance characteristics such as temperature retention, sound deadening, and rigidity, and can allow a steel fixture to better mimic one made of cast iron at significantly less expense. The fixtures include metal fixtures with and without enamel coatings.
