Combining the look of stone with the strength of man-made materials



Cultured Marble is a composite polymer product formed when ground white marble is mixed with catalyst and color; then sealed with gelcoat.  The gelcoat protects the surface and results in a shiny non-porous look.  Because cultured marble is a composite product, it can be molded into bathroom sinks, countertops, shower walls, bath tubs and even products such as window sills.  Being non-porous it is more protected than natural marble and stone and less vulnerable to damage and staining.

cut granite


Cultured Granite is also a cast composite made with a similar process to cultured marble, but using a different filler.  The end product has an aggregate look similar to what major solid surface manufacturers are creating.

Just as with cultured marble, our cultured granite can be molded into bathroom sinks, countertops, shower walls, bath tubs and other products.  It has a clear Gel-Coat finish, which protects the product.
