This sink is a dual mount and can be installed as an under-mount. The dual bowls have a low divider, letting you have the benefit of both wash and drying kitchen tasks, and using less water. Because the divider is low, you still have plenty of room to accommodate larger dishes and bakeware items. With benefits long known to design professionals, this sink is 80% natural stone which helps it to be resistant to stains and scratches. The nonporous surface is hygienic and helps to ward off microbes. Because of its material composition, it can withstand thermal shocks and temperatures up to 560 degrees Fahrenheit. The rear placement of the drain provides you with more under-counter space for storage. Stone is naturally sound-absorbing for a quieter kitchen. Please tighten the drain by hand during installation to avoid cracking the sink.
