Product Overview
The MSI Single Bowl 3018 Stainless Steel Undermount Sink (Model: SINK-3018) is a full-sized, professional kitchen basin engineered for busy culinary environments and residential kitchens alike. Crafted from high-grade 18-gauge 304 stainless steel using a seamless drawn manufacturing process, this 30" x 18" sink offers an expansive, open basin that easily accommodates large stockpots, sheet pans, and heavy cookware.
Designed for undermount installation beneath solid surfaces like quartz, granite, or marble, the 3018 model delivers a flush countertop transition that makes sweeping crumbs and spills directly into the basin simple and fast. Equipped with heavy-duty sound-dampening pads, a protective undercoating, and a durable brushed satin finish, it minimizes water noise while resisting scratches, denting, and thermal shock.

Installation & 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 the official MSI 3018 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 & 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 use to prevent hard water mineral deposits and spot buildup.
