With its heavy-duty 16 gauge T-304 stainless steel construction, this sink is built to withstand the rigors of daily kitchen use while complementing modern countertops.
What sets this sink apart is the combination of practical features and thoughtful engineering.

Comparing the Picks
The KRAUS KBU44 is a 32-inch, 18-gauge single bowl. The Lordear 33-inch workstation sink has a deep basin and accessories. The KRAUS Standart PRO KHU100-30 is a 30-inch, 16-gauge single bowl.
Steel Thickness
Gauge describes steel thickness: lower numbers mean thicker steel. Sixteen-gauge sinks feel sturdier and resist dents better, while 18-gauge sinks are lighter and usually cost less. Both work well when paired with sound pads and undercoating.
Sizing to Your Cabinet
A sink is usually a few inches narrower than the base cabinet. Measure the inside width of the cabinet and the countertop depth before ordering, and check the bowl depth for comfortable reach.
Countertop Compatibility
Undermount sinks need solid-surface countertops such as granite, quartz, or solid surface. They are usually installed by the countertop fabricator, so ask whether mounting is included in your quote.
Keeping It Looking Good
Wipe the sink dry after use to prevent water spots, clean with mild soap or a stainless cleaner, and avoid steel wool, which can leave rust marks. A bottom grid protects the finish from heavy pots.
Drain Placement
Rear or offset drains leave more storage under the sink and keep water from pooling where you work. Center drains are common and easy to plumb.
Noise Reduction
Rubber pads and spray-on undercoating dampen the sound of running water and clattering dishes.
Faucet Pairing
Choose a faucet with enough height and reach for the bowl. Pull-down sprayers make rinsing large pots easy.
Accessories
Basket strainers, bottom grids, and roll-up drying racks add function. Check what comes in the box.
Common Mistakes to Avoid
Do not forget that undermount installation needs solid countertops. Avoid harsh cleaners, and measure carefully before buying undermount sinks.
Warranty and Support
Many stainless sinks carry long warranties against defects. Register the product and keep the receipt and model number for any claims.
Planning the Installation
Order the sink before the countertop is fabricated so the cutout matches. Share the sink template with your installer.
