Product Overview
The MSI Single Bowl 18G Drawn 2318 Stainless Steel Undermount Sink (Model: SINK-2318) is a spacious, medium-to-large single-basin sink designed for primary kitchen work zones, large islands, and laundry utility stations. Formed from a single sheet of heavy-duty 18-gauge 304-grade stainless steel using a seamless drawn manufacturing process, this 23" x 18" sink provides maximum internal basin volume without taking up excessive countertop space.
Engineered for undermount installation, the 2318 model sits flush beneath solid surface materials like quartz, granite, or marble, allowing easy sweeping of crumbs and spills directly into the bowl. Featuring a professional brushed satin finish, protective undercoating, and sound-absorbing rubber pads, it effectively dampens noise from dishware and running water while resisting daily scuffs and stains.

Installation & Handling Guidelines
⚠️ IMPORTANT: UNDERMOUNT SINK INSTALLATION PROTOCOL
-
Countertop Material Compatibility: Intended for solid surface materials such as quartz, granite, marble, or quartzite. Not recommended for laminate countertops unless specialized undermount support systems are installed.
-
Fabrication Cutout Template: Always use the physical sink or official MSI 2318 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% silicone sealant along the flange edge to ensure a watertight seal.
-
Standard Plumbing Opening: The 3.5-inch drain opening fits 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.
