The Cultured Collection
The Cultured Collection consists of four different material types:
Marble, Onyx, Granite and Solids. They are collectively classified as Cast Polymer. All materials are available in a wide array of colors and can be molded into a wide variety of shapes to meet diverse design needs.

Tri-City Marble cast polymer products are made by chemically bonding a pulverized stone filler (
DOLIMITIC LIMESTONE) with a high quality POLYESTER RESIN to create a matrix. Pigments are added to achieve the desired coloration. The matrix is chemically fused with an "NPG" ISOPHTHALIC POLYESTER RESIN GEL COAT. Chemical catalysts are added in the process to control the hardening and rate of cure. Our products are designed to be resistant to water, heat, stains, abrasions and most chemicals. Scratches, chips and even cigarette burns are repairable.

Tri-City Marble ensures you will receive
consistent quality products by implementing quality control checks on incoming raw materials as well as the finished product. To ensure that our products exceed ANSI Z124.3 standards, thermal shock tests are conducted at our factory and also by an independent third party. Tri-City Marble products offer years of trouble-free performance as long as water temperatures do not exceed 150 Fahrenheit and units are properly installed.

Marble, Onyx and Solid materials are available in a virtually unlimited selection of colors. Standard colors are generally colors that coordinate with the more popular colors in American Standard, Kohler, and Eljer and Universal Rundle's current fixture color selections. Custom colors can be formulated for an additional charge.

  • Marble
    Colors are available with white veining on a fixture color background (mostly fixture color) or with a fixture color vein on a white on white (cloud) background (mostly white on white background). Other miscellaneous colors are available that duplicate the look of natural marble.
    Colors are available with a fixture color vein on a white onyx background (mostly white onyx). Onyx material has a translucent effect that provides a very luxurious appearance.
    Colors are also available in standard colors to coordinate with most current plumbing fixture selections. Pigments are mixed with the gelcoat to create a consistent color throughout the entire surface.
    Colors are available that have multiple colored specks within the same piece allowing them to coordinate well with most decors. Our Granite series is a homogenous blend throughout the entire matrix that is manufactured to exceed industry standards. Unlike competitive products that use calcium carbonate fillers or a thin sprayed on layer that won't hold up to rigorous use.
