Cultured marble

Cultured marble, also referred to as cast polymer,is a plastic composite blend of high strength polyester resin and marble dust formed in a variety of molds to make a single piece article such as bathtubs, shower pans and vanity tops with a surface that resembles marble. Though it is a less expensive alternative to marble, it can have more tensile strength.

Because cultured marble is made with a moulding process, it allows greater design flexibility than with stone. For instance, manufacturers of cultured marble can make a bathroom vanity with integrated bowl (or bowls). The manufacturing process encompasses several steps. One step uses a non-porous gelcoat on the counters and sinks which seals the product and prevents later mold and bacteria growth and staining. The process does not use hazardous material; the main risk is the flammability of the polyester resin.

The cultured marble industry is represented in many locations world-wide. The Kansas City, MO area is very prominent, with several large manufacturers: Leathers Cast Polymer, Bakers Marble, Complete Home Concepts, and The Onyx Collection. Some products carry a long guarantee, but long term durability has not been established since formulations and processing methods change with advances in the technology.
