Don’t let the name fool you, “Quartz sink” or “Titan Quartz sink” is a plastic composite, not a natural material. These plastic composites easily burn, stain and scratch when exposed to the everyday use of a kitchen sink. This creates a perfect environment for bacteria to accumulate. The result is an unsightly and unsanitary kitchen sink. Many companies have experimented with this material and were quickly disappointed by the results. For quality, longevity, stain, and bacteria-resistance sink, a true Fireclay material is the best investment.
