21" Undermount Porcelain Enameled Steel Single Bowl Kitchen Sink in White Pintura™ Porcelain Enameled Sinks offer timeless appeal similar to classic cast iron sinks, with an extremely resilient, lightweight steel core that eliminates the need for specialized installation. Made from durable dent-resistant T304 steel, Pintura sinks are coated with high-grade porcelain enamel and double-fired at high temperatures of 1500°F to create a virtually indestructible high-gloss finish that is resistant to chips, stains, and scratches, and will never rust or corrode. The perfectly smooth non-porous surface prevents the growth of bacteria for a healthier and more hygienic kitchen. While they echo the premium look of cast iron sinks, Pintura sinks are 65% lighter, and do not require specialized installation. Designed for a fresh modern look, the tight-radius corners are easy to keep clean with minimal maintenance. Ultra-quiet NoiseDefend™ sound barrier technology with thick super-silencer pads and protective foil layer eliminates noise and vibration when the sink is in use. Engineered for easy draining, the gently sloped sink bottom prevents water from pooling, with an optimized angle that keeps glassware from tipping over. Undermount installation creates a seamless transition between sink and countertop for a beautifully finished look, and allows you to wipe water and food particles straight into the sink. An inexpensive and easy-to-install way to transform your kitchen, Pintura Series Sinks offer the perfect combination of extraordinary durability, stylish versatility, and lasting value.
