Compact Footprint and a Clean Undermount Fit

The Karran U-1113 is an 18-gauge stainless steel bar and prep sink designed to undermount into granite, quartz, or solid surface countertops. Its 11-1/2 inch side-to-side length fits tight countertop runs and island inserts where a standard kitchen sink would not leave room to work.

Key Features

• 18-gauge stainless steel construction gives the bowl solid wall thickness for a bar or prep location that sees daily use.
• Single bowl configuration maximizes the usable basin in a compact footprint.
• Undermount installation into granite, quartz, or solid surface countertops for a flush, seamless counter edge.
• 15-inch minimum cabinet width makes it compatible with narrow base cabinets and tight island runs.
• 3-1/2 inch drain opening accepts standard bar-sink basket strainers.
• IAPMO certified to meet plumbing product standards.

Where a Compact Bar Sink Does the Most Work

A full-size kitchen sink solves the main cleanup problem but leaves nothing for prep, bartending, or a quick rinse at a secondary station. This sink fills that role. It fits into a 15-inch-wide cabinet, so it works in spaces that a standard single-bowl would never occupy: the end of a kitchen peninsula, a wet bar in a living or dining area, a butcher-block island with limited depth, or a secondary station in a high-volume kitchen where two wash points beat one. The single bowl keeps the full interior available without a divider cutting into usable space.

18-Gauge Stainless in a Brushed Stainless Finish

At 18 gauge, the steel wall is thick enough to resist flexing and dampen the sound that thinner stainless bowls tend to amplify. The stainless steel finish is consistent across the bowl and resists the surface oxidation that lighter-gauge or lower-alloy steel is prone to over time. Because the sink undermounts, the countertop edge meets the bowl cleanly from above, leaving no rim ledge to trap water or crumbs at the counter-to-sink transition.

Planning the Install

This sink is built for undermount installation and is not designed to drop in from above. It requires a countertop material that supports undermounting, specifically granite, quartz, or solid surface. The cabinet below needs a clear interior of at least 15 inches wide to accept the 13-1/2 inch front-to-back sink dimension. This is a sink to spec into a new countertop fabrication rather than retrofit into an existing cutout. The IAPMO certification confirms the sink meets the plumbing product requirements that most local codes reference, so it is straightforward to pull a permit on.

A Tight-Space Sink That Installs the Right Way

Choose the Karran U-1113 when the plan calls for a stainless bar or prep bowl in a space where cabinet width is limited and a clean undermount finish matters.
