An online catalog showcases the many bath products that can be created from concrete. The Web site's online catalog ( www.concretenetwork.com/bathroomproducts) shows how decorative concrete can be used for bathroom vanities, sinks, and tub and shower surrounds. Concrete can be molded into geometric or curved shapes and colored in an array of shades. "People sometimes still think of concrete as gray and boring," says Jim Peterson, president of the Web site. "But homeowners are flabbergasted by the beautiful results."
