You want a 27-inch undermount sink that fits your cabinet and your daily routine, so focus on steel thickness, depth, and if you need a workstation ledge. Some picks offer 27 inches as a selectable size option; where a sink only comes in a near size, we matched the closest same-type model so you know exactly what fits your cabinet.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Most 27-inch sinks need a 30-inch minimum base cabinet, so measure before you buy a 27-inch undermount kitchen sink that will not fit your existing countertop space.
Our Picks at a Glance
How To Choose The Best 27-Inch Undermount Kitchen Sink
Before you fall for a glossy photo, check three things: the gauge of the steel, the interior bowl size, and the minimum cabinet width. These three numbers decide whether your new sink will feel solid, hold your largest roasting pan, and actually slide into your existing base cabinet.
Steel gauge matters more than the brand name
The gauge number tells you the thickness of the steel. A lower number means thicker metal. A 16-gauge sink is roughly double the weight and rigidity of an 18-gauge one, which means less drumming noise and less chance of denting when a heavy pot drops in. Some buyers return thinner sinks after feeling the difference, so it pays to prioritize 16-gauge from the start.
Bowl depth and interior width do the real work
Outer width is only the start. Interior dimensions and depth tell you whether a full cookie sheet lies flat and whether a stockpot fits without splashing. A 10-inch deep bowl contains mess and splatter well, but that depth can clash with a garbage disposal in tight under-cabinet plumbing, so measure your wall drain height before committing.

In‑Depth Reviews
1. Lordear 27 Undermount Workstation 27×19
Our pick — over 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
A complete meal-prep station that arrives with its cutting board, colander, and drying rack in the box.
What wins people over here is the quality-per-dollar equation. Built from dent-resistant T304 stainless steel in TRU16 real 16-gauge, the bowl reads as heavier and more rigid than the thinner alternatives, which owners notice the moment they lift it. The 19-inch front-to-back depth gives you a touch more working room than the 18-inch models, and at just 10 pounds it is a remarkably light shell to maneuver into place during a remodel.
The workstation ledges on the front and back turn the sink into a sliding track, so the included wood cutting board, colander, and roll-up rack glide right over the bowl while you prep. Buyers report the sink is quiet in use and easy to keep clean, and they note the drainage grooves send water toward the hole without pooling. The trade-off shows up in the finish, which a few owners find prone to water spots and scratches with heavy use, so a rinse grid matters here.
Keep the 30-inch minimum cabinet size in mind before ordering. The package also includes bottom rinse grids, a basket strainer drain, a cutout template, and mounting clips, which spares you most of the extra shopping a bare sink demands.
Why It Wins
- Full accessory kit: cutting board, colander, roll-up rack included
- TRU16 real 16-gauge T304 resists dents and rust
- Workstation track expands counter space over the bowl
The Fine Print
- Finish can show water spots and scratches over time
- Cutting board marks easily per some long-term owners
- Needs a 30-inch minimum base cabinet
Reach for it if: you want one box that delivers a sink plus the meal-prep extras without a second shopping trip.
Look elsewhere if: your priority is a finish that hides every fingerprint, since polished stainless demands regular wiping.
2. Lordear 27 Undermount Deep Single Bowl 27X18
The deep, fabricator-approved bowl that pros install for clients and then buy for their own homes.
If you want to feel the difference between gauges, this is the sink to hold. At 24.9 pounds, it weighs about two and a half times as much as the 10-pound workstation Lordear above, and that mass translates into a solid, drum-free feel under running water. The T304 16-gauge panel is 1.5mm thick, and the R10 tight-radius round corners give it extra capacity while keeping food from lodging in sharp crevices.
Owners who work in kitchens professionally report buying Lordear for client installations and never having an issue, calling the build durable and well made. The “pretty” factor gets its own praise — owners mention the sink is “perfect and so pretty” in daily use. Heavy-duty sound guard padding and undercoating cut the clatter of dishwashing, and the brushed finish does a decent job hiding everyday wear.
The honest catch is the drain flange. Owners planning a garbage disposal will find the included strainer assembly will not mate with it, so budget for a separate connector before install day. The included bottom rinse grid also protects the steel from scratches while letting water flow beneath dishes.
Professional-grade feel: the 24.9-pound weight and 1.5mm-thick panel give it a sturdiness that thinner sinks simply lack.
Plan ahead: order a garbage disposal flange separately, since the stock drain assembly is not compatible.
Best for: cooks who want a deep, heavy, round-corner bowl and do not mind sourcing one extra drain part.
Not for: anyone who expects a drop-in-ready disposal hookup straight from the box.
3. Sarlai 27 Undermount Kitchen Sink 27×18
The extra-deep 16-gauge bowl that owners upgrade to after returning a flimsier 18-gauge first.
Anyone who has handled a thin sink knows the difference the moment they pick this one up. At 25 pounds, the Sarlai is the heaviest of the standard bowl options here and roughly two and a half times the 10-pound workstation Lordear, built from T304 TRU16 gauge steel with a commercial-grade brushed finish. A 10-inch extra-deep bowl swallows large roasting pans, and the R10 angle expansion increases usable capacity while the rear-set drain frees under-sink storage.
The buy-it-once advice shows up in owner stories. One buyer explicitly ordered an 18-gauge sink first, returned it, and then chose this 16-gauge model, calling it much heavier and very well built. The 3mm sound-deadening material plus heavy paint undercoating keep the bowl quiet and protect the cabinet from condensation, which matters in climates where temperature swings cause moisture.
Drainage earns mixed feedback rather than universal praise. Some customers note water flows fast thanks to the X-shaped guide, while others find food debris lingers, so a strainer habit helps. The standard 3-1/2-inch drain opening fits most garbage disposal units, and the package includes a roll-up drying rack, bottom rinse grid, and template.
Built To Last
- Heaviest standard bowl here at 25 lbs with TRU16 gauge
- 3mm sound-deadening layer quiets dishwashing noise
- 10-inch depth handles large pots and trays
What To Watch
- Food debris drainage is mixed in owner experience
- Scratch resistance gets mixed feedback over time
- Rear-set drain may sit far from existing plumbing
Choose this if: raw heft and a deep basin are your top two priorities in a single bowl.
Think twice if: you want a drain positioned front-and-center to match old plumbing.
4. Logmey 27 Inch Undermount Sink 27x18x9
A 9-inch-deep profile that solves the tight-plumbing problem most deep bowls create.
If your wall drain sits high, a full 10-inch basin won’t fit, but this Logmey steps down to a 9-inch exterior depth with an 8.75-inch interior, so you get a single bowl without redoing the plumbing. Renovators have swapped it in for a 30-inch 50/50 split sink, and the payoff is clear: large sheet pans that never fit the old divided bowl now lie flat.
The construction is a heavy-duty 16-gauge SUS304 stainless steel with a commercial-grade brushed finish. An anti-condensation coating on the back plus a 3mm-thick noise-reducing rubber mat protect the cabinet and hush the running water. Owners call the soundproofing outstanding, with one going so far as to award six stars for how quietly it performs.
Appearance draws consistent praise, especially alongside quartz and stone countertops. The one recurring aesthetic gripe is the laser-engraved logo on the bowl, which a few owners find less elegant than the sink itself. The rear-set 3.5-inch drain hole matches most garbage disposal systems, and the box includes a roll-up drying rack, drain assembly, bottom rinse grid, and template.
Shallow-bowl hero: the 9-inch depth fits under cabinets where a 10-inch basin never will.
Style note: expect a clean look with the caveat that the engraved brand logo is visible on the steel.
Grab this if: your plumbing or cabinet height cannot accommodate a deeper 10-inch bowl.
skip it if: you want maximum water depth for soaking large stockpots.
5. SANYCASA 27 Inch Workstation Sink
A workstation sink with an 11-gauge, 3mm-thick edge that refuses to warp under heavy use.
Most sinks on this list stop at 16-gauge, but this SANYCASA pushes the edge thickness to 11-gauge at 3mm, which is what prevents the rim from bending when you lean a cast-iron skillet against it. The SUS304 premium stainless body resists stains and corrosion, and the R10 radius rounded corners make wiping out the bowl a single smooth pass. An anti-condensation coating plus thick silicone pads keep noise and moisture in check.
The integrated single-tier rail accepts sliding accessories, and the package arrives with a cutting board, colander, stretchable roll-up drying rack, and bottom rinse grid. Reviewers point out using the inserts far more than expected, turning the sink into a staging area for meal prep. The X-shaped drain grooves slope toward the opening so water does not pool, and an openable lid on the pipe catches food debris before it clogs.
Where buyers split is on the included drain and plumbing, which a few describe as cheap plastic that they swapped for PVC and a stainless steel drain. One owner who inspected the box before install was impressed enough by the 11-gauge steel to plan a Kohler basket strainer upgrade. Durability reports are mixed, with a minority noting dents on arrival, so inspect the packaging carefully.
What Impresses
- 11-gauge 3mm edge resists warping
- Rounded R10 corners simplify wiping
- Rail system with cutting board, colander, rack included
What To Budget
- Stock drain is plastic and often replaced
- Occasional reports of dents in transit
- Accessories can limit open bowl space
Pick this if: edge rigidity and a built-in accessory track matter more to you than the drain hardware.
Pass if: you want a sink that is fully ready to plumb with zero upgrades.
6. KRAUS Fairlane 27 Undermount Sink
The brand that contractors recommend, with an offset drain that frees under-sink storage.
KRAUS earns its reputation through consistency, and the Fairlane shows why. This is an 18-gauge T-304 stainless sink rather than a 16-gauge, so it is not the thickest option here, but the 23.2-pound build still feels dense and sturdy in hand. The 9-inch depth keeps a lower profile than the 10-inch bowls while the 27 x 18.5-inch footprint still cradles large pots, and the offset drain boost usable floor space in the cabinet below for storage bins.
Owners say the undermount design pairs cleanly with stone countertops, leaving no rim to trap crumbs. The Noisedefend soundproofing (silencer pads on all sides) and full anti-condensation undercoating keep the bowl quiet and the cabinet dry. Shoppers say one family member converted the whole household to KRAUS after feeling the build quality.
The honest caveat is that the finish scratches and stains a bit more easily than some rivals, though owners still praise how sturdy and heavy the material feels. The included stainless sink grid, drain assembly, hardware, and cutout template make this installation-ready, and the sloped bottom with channel grooves drains without pooling.
Balanced performer: a trusted mid-range brand with an offset drain and quiet pads, if not the thickest steel.
Expect upkeep: the brushed surface shows scratches more readily than heavier-gauge rivals.
Best for: buyers who want a reputable brand, a 9-inch depth, and extra under-sink cabinet storage.
Not for: anyone dead-set on maximum steel thickness above all else.
7. Ruvati 27-in Offset-Drain Workstation RVH8570
A 34-pound workstation heavyweight with a patented foldable rack and a 1-inch sloped floor.
This is the sink for buyers who treat the workstation category seriously. At 34 pounds, the Ruvati RVH8570 carries real mass in its 16-gauge T-304 steel, and the 1-inch slope toward the drain means water and debris rush out rather than sit in a puddle. The offset drain installs on either the left or right side, which opens cabinet space below and lets you match existing plumbing.
The LedgeFit design is the differentiator: ledges on the front and back accept 40-plus optional accessories that interchange across Ruvati workstation sinks, so you can add tools years from now without replacing the bowl. The included foldable drying rack uses a patented silicone frame, and the solid sapele wood cutting board resists water damage and scratches. Buyers report the sink cleans easily and dries quickly, shining up with minimal effort.
The trade-off is price positioning — this sits above the budget tier — and a minority of owners note water spots on the finish while others flag that stainless steel will show some scratching no matter the protection. The 3.5-inch drain opening fits any standard garbage disposal, though the included drain is for standard plumbing only and the disposal flange comes from your unit.
Workstation benchmark: the 40+ LedgeFit accessory ecosystem plus a 1-inch sloped floor justify the premium.
Keep perspective: even stainless this good can spot with hard water, so wipe it down.
Reach for this if: you plan to grow your accessory setup over time and want a drain that routes around clutter.
Look elsewhere if: you need a bare-bones sink and will never use a cutting board or rack on a ledge.
8. Ruvati 27-in Round-Corner Workstation RVH8327
The heaviest bowl on this list at 39 pounds, with rounded corners built for easy wiping.
Weight tells the story here: at 39 pounds, this Ruvati is the heaviest sink in the roundup, nearly four times the workstation Lordear above, so it feels rock-solid and low-vibration, unlike thinner bowls. The 16-gauge T-304 stainless body uses a center drain, not an offset one, with a sloped bottom and grooves routing water to the middle; rounded R10 corners leave no sharp seam for grime.
The interior bowl measures 25-3/8 by 16 by 10 inches deep, which owners confirm is large enough to lay a whole cookie sheet flat. The package includes a solid wood cutting board and a foldable drying rack that slide along the integrated single-tier track. A 3.5-inch standard drain fits any garbage disposal, and the box arrives with a bottom rinse grid, basket strainer, decorative drain cover, and mounting brackets.
The consistent owner caveats are drainage and rust at the margins. Multiple owners mention the center-drain slope leaves some water standing, and a smaller group flags rust appearing at the top workstation corner weld, which improves if the area is kept clean and dry. The cutting board’s wooden handles also discolored for a couple of owners within the first weeks, so treat the wood.
Why It Stands Out
- 39 lbs of 16-gauge steel feels immovable once installed
- Rounded corners and a 10-inch bowl fit full cookie sheets
- Solid wood cutting board and foldable rack included
Watch Closely
- Center drain slope leaves some standing water for some owners
- Occasional rust line at the corner weld area
- 10-inch depth may clash with low wall plumbing
Choose this if: maximum heft and rounded easy-clean corners top your list and your drain sits center.
Pass if: your wall plumbing sits low, since the deep bowl is a tight fit beside a garbage disposal.
9. BLANCO Precis 27 Undermount Sink
A soft white granite-composite bowl that trades stainless upkeep for a matte, modern look.
Forget steel for a moment. This BLANCO is built from patented SILGRANIT, a granite composite the maker says resists heat, scratches, stains, chips, and impacts, and it arrives in a Soft White matte finish that changes the whole feel of a kitchen. Owners consistently say it looks more expensive than it is, and the color pairs cleanly with stainless appliances without showing every water spot the way bare metal does.
The undermount design with no exposed rim means you wipe crumbs straight into the bowl, and the Hygienic+Plus Surface Technology acts as a shield against liquids and dirt for easier cleaning. At 27.2 pounds it feels substantial, and the 9.03-inch depth plus 26.81-inch width is big enough that owners lay a full cookie sheet flat for washing. The 17.75-inch front-to-back dimension is a bit shallower than the 18 and 19-inch steel rivals, so check your counter depth.
The catch is that composite chips rather than dents. One owner dropped a knife and chipped the bottom within a month, and another found a small crack in a corner on arrival, so inspect before install. Basket strainer and mounting clips sell separately, which adds to the total cost, and durability feedback runs mixed even as appearance and easy cleaning draw steady praise.
Design-forward choice: the Soft White matte finish hides spots and adds a modern, expensive-looking accent.
Handle with care: composite can chip on hard impacts where steel would merely dent.
Best for: homeowners who want a non-stainless color that blends with the countertop and hides water marks.
Not for: clumsy kitchens where heavy pots and dropped knives are an everyday reality.
10. DELTA Faucet Lorelai Workstation Sink
A full Chef’s Kit of six accessories on a WorkFlow ledge, backed by a limited lifetime warranty.
DELTA aims this at the buyer who wants everything in one curated box. The Lorelai workstation sink comes with acacia cutting board with a mobile device holder, a roll-up drying rack with removable utensil holder, a self-draining silicone drying mat, a stainless bottom grid, and a drain assembly with cover. The drying rack holds up to 85 lbs and is heat-safe to 400 degrees F, which makes it genuinely useful for setting down hot pans straight from the stove.
The sink itself is heavy-duty TRU16 gauge stainless steel at 27 by 19 by 9.5 inches outside, with a spacious 25 by 16 by 9-inch bowl. Owners call it perfect for a mid-sized kitchen and note the rear-offset drain opens up cabinet storage below. The Noisedefend soundproofing with extra-thick pads on all sides plus anti-condensation undercoating keeps things quiet and dry, and the rounded EZClean corners wipe out without catching debris.
The honest trade-off is value: this is the premium-tier pick, and owners note the cutting board picks up watermarks and stains quickly even as the steel itself holds up with no rust after extended use. The SatinSheen finish resists rust and corrosion, and the WorkFlow ledge turns the sink into a genuine prep station. The listed item weight of 16 g looks like a data error, so judge the heft by its TRU16 steel spec instead.
All-in-one luxury: six accessories plus a WorkFlow ledge make this a complete food-prep station from the start.
Expect to oil the wood: the acacia board shows marks quickly, so care for it like any butcher block.
Reach for this if: you want a single premium purchase that includes every accessory and a lifetime warranty.
Look elsewhere if: your budget favors a simpler sink and you already own cutting boards and racks.
Understanding the Specs
Steel Gauge and Grade
The gauge number tells you how thick the metal is, and a lower number means thicker steel. A 16-gauge sink feels heavier and resists dents better than an 18-gauge one, so it is the thickness most buyers in this category target. The grade, usually T-304, tells you the alloy resists rust and corrosion from daily water exposure, which is why nearly every pick here lists it.
Bowl Depth and Cabinet Fit
Depth works in two directions. A 10-inch bowl contains splatter and holds large pots, but it needs enough room under the cabinet for the drain pipe to slope downward. A shallower 9-inch bowl fits tighter spaces. Almost every 27-inch sink here requires a 30-inch minimum base cabinet, so confirm that width before you buy.

Final Thoughts: The Verdict
For most buyers, the 27-inch undermount kitchen sink winner is the Lordear Workstation 27×19 because it bundles a 16-gauge bowl with a cutting board, colander, and drying rack at a mid-range price. If you want a deep, heavy bowl that pros install for clients, grab the Lordear Deep 27×18. And for a premium workstation with an expanding LedgeFit accessory ecosystem, the Ruvati RVH8570 is the one to reach for.
