The sink's reversible design also makes any kitchen sink specification easy to achieve. This kitchen sink is made of SILGRANIT, a patented, certified granite composite material that is engineered to take on the toughest kitchen tasks. SILGRANIT is heat, scratch, stain, chip and impact resistant, making it stronger and more durable than other sink materials. It will not blister, burn, melt, or discolor from hot pots, pans or baking sheets straight from the oven. Beautiful and highly functional with its non-porous, hygienic surface, it pushes away liquids and residue resulting in a low maintenance, easy to clean, long-lasting material.
