Vikrell material is a composite material that is made with a combination of filler, fiberglass and resin. This material is also exclusively used to make Kohler products and is molded using compression in large presses to create baths, showers, lavatories and kitchen sinks.
As of 2015, Vikrell is used in the construction of various types of showers, baths, whirlpool tubs and bath showers under the Sterling brand. Vikrell products come in white, almond or biscuit, and they can have a swirl-gloss finish or a high-gloss finish. Customer limited warranties cover fixtures made of Vikrell, including a three-year limited commercial warranty for kitchen sinks.
