The Lordear 33 inch undermount kitchen sink is a workstation-style sink designed for homeowners who want to maximize functionality in their kitchen. It is ideal for those who cook frequently and need extra prep space without expanding countertops. The sink comes with a cutting board, colander, roll-up dish rack, and bottom grid, turning the basin into a versatile workspace.
Standout features include the 16 gauge SUS304 stainless steel construction, which provides exceptional durability and a commercial grade brushed finish that resists scratches. The deep 10 inch bowl allows you to soak large cookware, while the workstation ledges let you slide accessories across the sink.

Comparing the Picks
The Lordear 33-inch undermount sink has a deep 10-inch basin with workstation features. The KRAUS Standart PRO KHU100-30 is a 30-inch 16-gauge single bowl. The KRAUS KHU100-32 offers the same heavy-duty construction in a 32-inch size.
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 install undermount sinks on laminate. Avoid abrasive pads, and measure your cabinet before buying undermount stainless steel kitchen sinks.
