Product Overview
The MSI Single Bowl "SCO" 3218 Stainless Steel Undermount Sink (Model: SCO-18-BWL-3218) is a premium, oversized single-basin kitchen sink engineered for maximum culinary efficiency. Part of MSI's commercial-grade stainless steel collection, this 32" x 18" sink is drawn from a single sheet of heavy-duty 18-gauge 304-grade stainless steel, offering an expansive open bowl that effortlessly fits oversized stockpots, baking sheets, and heavy roasting pans.
Designed for undermount installation beneath solid surface countertops like quartz, granite, or marble, the 3218 model creates a seamless, rimless edge that allows you to wipe water and food debris directly into the bowl. Finished in a soft brushed satin luster and treated with heavy sound-dampening undercoating, it minimizes running water noise and dish rattling while resisting scratches, corrosion, and thermal shock.

Installation and Handling Guidelines
⚠️ IMPORTANT: UNDERMOUNT SINK INSTALLATION PROTOCOL
-
Countertop Substrate Compatibility: Designed specifically for solid surface materials such as quartz, granite, marble, or quartzite. Not recommended for laminate countertops unless specialized undermount support systems are installed.
-
Cutout Template Usage: Always use the physical sink or official MSI SCO 3218 cutout template to trace and fabricate stone countertop openings prior to installation.
-
Watertight Fastening: Secure the sink flange to the underside of the countertop using approved undermount mounting clips and brackets. Apply a continuous bead of 100% neutral-cure silicone sealant along the flange edge to guarantee a watertight seal.
-
Standard Plumbing Connection: The 3.5-inch drain opening accommodates all standard kitchen basket strainers, pop-up assemblies, and continuous-feed garbage disposals.
Care and Maintenance
-
Routine Cleaning: Wash regularly with warm water, mild liquid dish soap, and a soft microfiber cloth or non-abrasive sponge. Always wipe parallel to the brushed satin grain lines.
-
Avoid Harsh Chemicals: Do not use steel wool pads, wire brushes, chlorine bleach, or harsh acidic solvents, which can scratch the finish or compromise the steel’s protective oxide layer.
-
Preventing Water Spots: Towel dry after heavy use to prevent hard water mineral deposits and spot buildup.
