Just when you thought concrete might have reached its limit as a sophisticated interior spec, Denver-based Metallo Cast Sinks and Surfaces has taken the material one step further: The company fuses concrete and metal to create an inventive line of basins, vessel sinks, and countertops. The handmade sinks are cast in concrete and then coated in bronze, copper, nickel-silver, aluminum, brass, or pewter. A sealer is then applied to give the products a “living” finish—allowing the concrete and metal to age naturally. Metallo Cast Sinks and Surfaces, 303.307.8898; www.metallodesigns.com.
