    Single & Double Bowl Sinks

    Single bowl undermount sinks provide uninterrupted workspace for oversized cookware, sheet pans, and workstation-style kitchens. Double bowl configurations offer dedicated wash and rinse areas with both 50/50 equal and 60/40 offset layouts to suit different kitchen workflows and cabinet sizes.

    Bar & Prep Sinks

    Compact stainless steel bar sinks are ideal for kitchen islands, wet bars, beverage stations, and secondary prep areas where a full-size basin is unnecessary. Their smaller footprint maximizes usable countertop space while providing convenient functionality.

    16-Gauge & 18-Gauge Construction

    Stainless steel undermount sinks are available in durable 16-gauge and 18-gauge construction. Thicker 16-gauge steel offers greater dent resistance, quieter operation, and improved rigidity for high-use kitchens, while 18-gauge provides professional corrosion resistance at a lighter weight for standard residential installations.

    Apron-Front Sink Options

    Farmhouse-style apron-front sinks combine the durability of stainless steel with a distinctive exposed-front appearance. For projects requiring a different sink material, browse our selection of Porcelain Sinks designed for stone countertop installations.

    Choosing the Right Stainless Steel Undermount Sink

    Selecting the right sink depends on cabinet size, bowl configuration, steel thickness, and intended use. Large family kitchens often benefit from spacious single bowl designs, while double bowl models improve efficiency for washing and rinsing. For maximum durability and reduced noise, many fabricators recommend 16-gauge construction, while 18-gauge remains an excellent choice for standard residential applications.

    Proper undermount installation requires compatible mounting hardware and adequate countertop reinforcement. Browse our Sink Mounting & Installation Hardware for clips, brackets, and adhesive systems, and our Rodding Supplies for reinforcing stone around sink cutouts. BB Industries stocks professional Envy stainless steel undermount sinks trusted by countertop fabricators throughout North America.

    Frequently Asked Questions

    What is the difference between 16-gauge and 18-gauge stainless steel sinks?

    Lower gauge numbers indicate thicker steel. Sixteen-gauge sinks are heavier, quieter, more dent resistant, and better suited for high-traffic kitchens. Eighteen-gauge sinks provide excellent corrosion resistance and professional performance while offering a lighter, more economical option for standard residential installations.

    What size undermount stainless steel sink fits a 36-inch cabinet?

    A typical 36-inch base cabinet can accommodate a single bowl sink up to approximately 32 inches wide or a double bowl sink up to about 33 inches wide. Always verify the manufacturer's cutout template and interior cabinet dimensions before fabrication.

    How is an undermount stainless steel sink installed in granite?

    The countertop is fabricated with a precision sink cutout, the sink is positioned beneath the stone, and mounting clips, brackets, or adhesive systems secure it in place. A continuous bead of silicone creates the waterproof seal, while the exposed stone edge is polished to the desired finish.
