Check Price on Amazon

The Sarlai 28-inch stands out for its 16-gauge T304 construction, which buyers who upgraded from lighter sinks unanimously call out as substantially heavier and more solid. At 10 inches deep, the basin swallows full-size roasting pans and stockpots without the water line reaching the brim. The commercial-grade brushed finish hides the fine scratches that appear after months of scrubbing cookware.

Drainage is handled by a sloped bottom with X-shaped guide lines that push water directly to the rear-set 3.5-inch drain. This layout also frees up under-sink storage space compared to center-drain designs. The sound-deadening pads and thick bottom coating keep the sink quieter than most mid-range options, reducing the metallic ring when you set down a cast iron skillet.

Included accessories—a roll-up rack, a protective bottom grid, and a drain assembly—add real value. The grid prevents scratches from heavy pans, and the rack is useful for drying produce. The 31-inch minimum cabinet requirement fits standard framing, and the 19-pound weight makes the unit manageable for a single installer.

The Kraus KWU110-28 redefines sink utility with a built-in accessory ledge that lets a bamboo cutting board and roll-up dish rack slide directly over the basin. The TRU16 gauge stainless steel body feels dense and rigid, and the 10-inch depth gives you room to fill a 16-quart stockpot completely. Exterior dimensions are 28 by 19 inches, so the cabinet requirement jumps to 33 inches—a key planning detail.

Drainage is the one trade-off: several users report persistent water pooling in one corner, especially without the bottom grid lifting dishes above the basin floor. The sloped design and channel grooves help, but the issue is consistent enough to note. The included bamboo cutting board looks thin compared to standalone boards, and it requires periodic oiling to prevent cracking.

Kraus backs this sink with a limited lifetime warranty, and the accessory set—cutting board, drying rack, bottom grid, and drain assembly—covers nearly every daily prep need. The satin finish resists water spots better than polished stainless, and the rounded corners simplify wipe-downs. If your countertop can fit the 33-inch minimum cabinet, the workstation concept genuinely reduces counter clutter.

Lordear delivers a 10-inch-deep basin with 16-gauge T304 steel at a price point that undercuts many competitors by a noticeable margin. The brushed finish is uniformly applied, and the R10 tight-radius corners prevent the grime buildup that plagues sharp-cornered sinks. Fabricators who install these regularly report zero bowing or finish defects across multiple units.

The X-shaped diversion waterlines combine with a gentle slope to channel water efficiently toward the rear drain. The sound-proof pads are noticeably thick, and the full-body outer coating stops condensation from forming on the underside—a direct protection for the cabinet base. Included accessories (bottom grid, roll-up rack, drain assembly) are all functional and match the sink’s quality.

At 25.4 pounds, the Lordear feels substantial during installation. The 31-inch cabinet minimum matches standard framing, and the cutout template simplifies the countertop prep. The only real gap is the lack of a decorative drain cover, but the included standard basket strainer works reliably with garbage disposals. For a deep basin that doesn’t compromise on steel thickness, this is a smart mid-range contender.

The Kichae sink’s 32-pound weight signals its 16-gauge pedigree immediately—two people should handle the install. The brushed satin finish resists the fine scratch web that degrades polished surfaces over time. At 9 inches deep, the basin is slightly shallower than the 10-inch options, but the overall sturdiness makes up for it when you’re scrubbing a heavy Dutch oven.

The X-shaped drainage guides work effectively with the sloped bottom, and the heavy-duty sound guard undercoating plus rubber padding keeps the noise profile low. Users specifically call out how the 9-inch depth hits a sweet spot for hand-washing dishes without excessive bending. The standard 3.5-inch drain opening fits all major garbage disposals without an adapter.

Kichae includes a stainless steel bottom grid, a roll-up drying rack, and a strainer with a decorative cap. The packaging is heavy custom foam that protects the sink during shipping. The 31-inch cabinet minimum is consistent with most 28-inch undermount models. For anyone who prioritizes mass and rigidity over maximum depth, this is a worthy entry.

The Ruvati RVM5077 breaks from the single-bowl trend with a true 50/50 split, giving you two 12.75-inch-wide bowls at 8 inches deep. The 16-gauge T304 steel construction is evident in the 30-pound weight, and the commercial brushed finish is consistent across both basins. A 30-inch minimum cabinet fits this sink because the exterior width is 28.5 inches.

Each bowl includes a stainless steel bottom grid and a decorative drain cover. The divided layout lets you keep a soaking bowl on one side while using the other for rinsing, but the 8-inch depth limits how much water you can use for large pots. The straight sides and gently curved corners make both bowls straightforward to clean, and the sound-proof coating on the underside quiets the dual-basin echo that plagues lighter sinks.

Installation is straightforward with the included template and mounting brackets. The rear drain positions free up space under the sink for a disposal on the larger side. Ruvati’s reputation for fitting standard US plumbing is well earned, and the cUPC listing confirms code compliance. This is the right choice if you prefer a divided workflow and can accept the reduced depth vs. a single 10-inch basin.

BLANCO brings a 26-inch base width and 18-gauge T304 stainless steel to this 28-by-18-inch undermount sink. The 18/10 chrome-nickel content is higher than many budget options, which improves corrosion resistance over the long term. The 9-inch bowl depth is standard, but the subtle curvature of the interior corners prevents the hard-to-scrub crevices found on cheaper stamped sinks.

No drain assembly is included, so you’ll need to purchase one separately—a detail that surprises some first-time buyers. The sound-dampening coating on the bottom is effective enough that users consistently praise the quiet operation. The brushed finish holds up well against daily scrubbing, and the lack of sharp corners simplifies wiping. The limited lifetime warranty reflects BLANCO’s confidence in their material durability.

At 22.4 pounds, the sink is lighter than 16-gauge alternatives, but the build quality from a brand with decades of sink manufacturing is consistent. The sink requires a 30-inch interior cabinet space, which is tighter than the typical 31-inch requirement. If you trust a legacy name and prefer to source your own drain assembly, this is a solid premium pick without the workstation extras.

The Lonsince granite composite sink offers an alternative to stainless steel with a solid white finish that matches lighter countertops. The material resists scratches and impact better than enameled steel, though users consistently note that it stains from coffee, tomato sauce, and turmeric unless you scrub with Bar Keepers Friend after each use. The 9-inch depth is standard, and the 41-pound weight reflects the dense composite material.

The workstation design uses overhanging front and back lips as tracks for the included accessories: a gold portable dish tub, foldable dish rack, sink strainer, sink protector, and cutting board. The gold accents add a warm tone that softens the white finish. The sink supports both undermount and drop-in installation, which adds flexibility if your countertop material requires a rim.

Care is more involved than stainless steel—the cutting board must be hand-washed and oiled to prevent cracking, and the white surface demands daily maintenance to stay bright. The 28-inch base width and 31-inch cabinet minimum match standard dimensions. If you love the look of a seamless white workstation and are willing to invest in upkeep, the visual payoff is significant.

The Mocoloo brings a PVD gunmetal black finish that is genuinely fingerprint-resistant and water-spot-repellent, solving two common frustrations with stainless steel. The T304 base metal ensures rust resistance, while the black coating hides the minor scuffs that develop over years of use. The 9-inch depth is paired with a 28-by-18-inch exterior that fits a 31-inch cabinet.

X-shaped drainage grooves route water effectively, and the R10 tight-radius corners limit food buildup. The extra-thick rubber sound-dampening pads and full-body anti-condensation coating keep noise levels low and protect the cabinet from moisture. The included drain assembly fits standard 3.5-inch garbage disposals, and the cutout template simplifies installation.

The gunmetal finish works best in kitchens with dark hardware or black appliances—matching it to brushed nickel faucets can look mismatched. The 5-year warranty and 90-day return policy add confidence. For a buyer who wants a modern matte-black aesthetic without the maintenance of granite composite, this is the strongest colored option at this size.

The MENATT 28-inch undermount sink is designed for tighter cabinets, requiring only 30 inches of interior space while still offering a 28-by-18-inch exterior footprint. The 18-gauge T304 steel is lighter at 18 pounds, which makes installation easier for a single person, but the thinner metal means more potential for denting if heavy cast iron is dropped. The 9-inch depth is adequate for most washing tasks.

The slanted base channel and X-slot design prevent standing water. The sound-dampening rubber pads and anti-condensation coating are present, though thinner than 16-gauge competitors, resulting in slightly more noise during heavy use. The rear-set 3.5-inch drain opens up under-sink storage and accepts standard disposals.

The sink ships in custom anti-collision foam, and the included drain kit and mounting hardware simplify setup. The dual installation type (undermount or drop-in) adds versatility if your countertop can accommodate either. For a budget-focused build or a tight cabinet, this sink delivers the 28-inch undermount form factor without requiring you to expand the cabinet footprint.
