You want one basin that does the chopping, the rinsing, and the drying without turning your counter into a yard sale of boards and bowls. An undermount workstation sink solves that: the rim has a built-in ledge, so a cutting board, colander, or roll-up rack slides over the bowl and out of the way. The trick is getting the one whose steel, depth, and ledge depth actually match your cabinet, your pots, and your patience for wiping. Below, the sink that sits on top of this category is Kraus’s 16-gauge single bowl, a four-and-a-half-plus star performer among tens of thousands of owners — but there are 13 more worth reading before you commit a countertop cutout to it.
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.
Bowl depth, gauge, corner radius, and minimum cabinet width decide whether a sink feels like a workspace or a chore — and that is exactly what this rundown compares across the widest spread of kitchen sinks undermount buyers actually install.
Top Picks
How To Choose The Right Undermount Workstation Sink
The single most common mistake is buying by bowl width instead of cabinet width. A 32-inch sink usually wants a 36-inch base cabinet, and a 45-inch sink wants a 48-inch one. Measure the inside of the cabinet box, not the old sink, and check that your faucet’s spout reaches far enough forward to land over the bowl.
Start with the steel gauge
Gauge is the thickness of the stainless, and lower numbers mean thicker metal. A 16-gauge sink feels solid under a stock pot and dulls the clang of dropped silverware. An 18-gauge sink is still fine, but it is thinner and a bit noisier unless sound pads do the heavy lifting.
Then check the ledge and what sits on it
The front and back rails are the whole point of a workstation sink. More rail depth means accessories sit lower and steadier; a shallow rail makes a full cutting board wobble. Check what ships in the box too, because a sink that includes a board, a rack, and a colander saves you buying them separately.
Match the bowl depth to your cookware
A 10-inch bowl swallows a stock pot and a baking sheet upright. A 9-inch bowl is easier to reach into and less of a stretch for shorter users. Deeper bowls also trap more splash, so tall pots stay contained.
Decide how much wiping you will tolerate
Shiny brushed stainless shows water marks, so most owners wipe the bowl dry after use. The drain slope is the other half of that story: a gentle slope keeps water moving, while a nearly flat bottom leaves debris in the corners for you to chase with a sponge. If you hate scrubbing, a rear-offset drain with real channel grooves is the friendlier layout.

Detailed Reviews
1. KRAUS KWU110-32
Our pick — 4.5+★ from 3,500+ verified ratings; the strongest balance of quality and price.
A 32-inch single bowl with a 10-inch depth and a 5-piece chef’s kit, sized for a 36-inch cabinet.
The 32-inch by 19-inch frame with a 10-inch deep single bowl gives you a basin that swallows a stock pot without a fight. The 16-gauge TRU16 stainless steel is the thicker end of the mainstream range, and the satin finish shrugs off fingerprints better than a mirror-polished bowl. The 5-piece chef’s kit — bamboo cutting board, roll-up dish drying rack, protective bottom grid, drain, and cover — means the ledge is useful on day one, not after another shopping trip.
What wins people over is the build quality: thick steel, clean welds, and a bowl that feels substantial when you slide a board across it. The integrated ledge is the reason owners stop stacking cutting boards on the counter, and the sloped base with channel grooves pushes water toward the drain. What buyers are less unanimous about is the drainage itself, since some find debris needs a nudge to reach the right-side drain, and scratch resistance draws mixed reports — the satin surface helps, but a dropped pan can still leave a mark.
One weight figure worth noting: at 26.5 pounds this sink is 7.5 pounds lighter than the 34-pound Dcolora and BoomHoze models, which makes a solo install less of a wrestling match. It still needs two people and a 36-inch minimum cabinet, so line up help before the countertop crew arrives.
What the steel and the ledge deliver
- 16-gauge TRU16 stainless with a satin finish that resists fingerprints and corrosion
- Full 5-piece kit included — cutting board, roll-up rack, bottom grid, strainer, drain cover
- 10-inch bowl depth fits tall pots and baking sheets upright
- Undermount fit removes the mounting deck, so crumbs wipe straight into the sink
Where it asks for patience
- Drain sits right side and a flat-ish slope means some food needs pushing along
- Bamboo board is lighter-looking than the advertised acacia in the photos
- Bottom grid has to be lifted to clean underneath
Go with this if: you want a single bowl that does prep and cleanup at the same spot and you have a 36-inch cabinet free.
Hold off if: your old plumbing sits left-of-center and you were hoping to keep it there — the right-side drain will need adjustments.
2. Ruvati RVH8591
The drain shifts left or right, so your under-cabinet space stops being a puzzle.
An offset drain is the answer to the question nobody asks until install day: where does the plumbing actually go? This Ruvati lets you set the drain on the left or the right, which frees up real storage space in the cabinet below. The bowl is 33 inches wide and 19 inches front-to-back, with a 10-inch depth, sitting over a 36-inch minimum base cabinet. The 16-gauge T-304 stainless comes with a commercial-grade brushed finish that hides scratches, and the 1-inch slope toward the drain is designed to send water and debris in one direction.
What separates this from a straight workstation is the accessory ecosystem. LedgeFit means 40+ optional accessories are interchangeable across Ruvati workstation sinks, so you can grow the setup later. The included sapele wood cutting board, foldable dish rack, and stainless steel bottom grid cover the essentials. The trade-off is that the included drain is meant for standard plumbing only, and a garbage disposal flange is not in the box — check your disposal’s flange before you buy or you will be improvising mid-install.
Best where the plumbing tried to win: the offset drain layout is the feature that matters here. If your current drain is off to one side, this collapses a plumbing headache into a five-minute decision instead of a rebuild.
The accessory shelf grows: LedgeFit interchangeability is rare at this level, and it means the board you buy today still fits the sink you swap in later.
Worth choosing when: your cabinet is 36 inches wide and you want a 33-inch bowl with an offset drain and long-term accessory compatibility.
Also know: disposal flange is not included, so budget for that piece if you are hooking up a garbage disposal.
3. Delta Lorelai 45-inch Workstation Kitchen Sink Undermount
Forty-five inches of stainless that turns a countertop into a two-tier prep station.
This is the largest bowl in the group by a wide margin: 45 inches long, 19 inches wide, and 10.5 inches deep, which means a 48-inch minimum cabinet. The two-tier WorkFlow ledge is the headline, because it lets you stack a cutting board up top while a colander or rack sits below, all over the same bowl. It ships with 11 accessories, including an acacia cutting board with a mobile device holder, a serving board set with mixing bowl and colander, a roll-up drying rack with utensil holder, a stainless drying rack, two bottom grids, a silicone mat, and the drain assembly.
The heavy-duty TRU16 16-gauge stainless and NoiseDefend sound-absorbing pads keep it quieter than an oversized basin has any right to be. The EZClean rounded corners and SatinSheen finish resist rust and corrosion, and the rear-offset drain frees up cabinet room below. What makes people happy here is the sheer sense of room: the appearance and the accessory set are the two things that draw the most approval, and the reaction is consistent — it looks like a showroom piece and it works like a prep shop. Scratch resistance is where the feedback splits, since some buyers report it can scratch and others find it holds up.
A real head-to-head: this bowl is 13 inches wider than the 32-inch KRAUS at 45 versus 32, which is the source of both its appeal and its fit problems. Check your cabinet twice before you commit.
Choose it if: you entertain often, have a 48-inch cabinet, and want the freezer-filling pot in the sink without a struggle.
Think twice if: your kitchen is compact — 45 inches of sink is a lot of the counter to give up, and it needs 48 inches of cabinet to sit.
4. Ruvati RVH8356
Double bowls, one ledge — the compromise for people who can’t give up the second basin.
A 60/40 split lets you wash in the big side and rinse in the small one without giving up the workstation rail. This one is 33 inches wide by 19 front-to-back, with a 10-inch bowl depth and a 36-inch minimum cabinet. The two bowls measure 18 by 16 inches on the left and 12 by 16 on the right. It is the heaviest sink among the Ruvati group at 52 pounds, which is bought weight — the 16-gauge T-304 steel and dual bottom grids account for the heft, and it feels solid the moment you lift it.
Owners who love it point to the workmanship: precision edges, thick rubber soundproofing, and the included sapele wood cutting board, foldable rack, colander, two bottom grids, and two decorative drain covers. The 3.5-inch drain openings accept standard garbage disposals. The honest trade-off is the one you always get with two basins and a rail: the corners are sharp, so debris loves to gather there, and the included rubber clamps have been known to trap grime if you leave them in place.
Why double-bowl owners stay loyal
- Two basins at 18 x 16 and 12 x 16 inches give separate wash and rinse zones
- LedgeFit compatible with the larger Ruvati accessory range
- Two bottom grids and two drain covers included
- Sharp inside corners for a modern, squared look
The maintenance reality
- Sharp corners gather food and need a brush to clear
- Rubber clamps can trap debris if left installed
- 52 pounds is a two-person install
This is the one for: households that pre-rinse and wash at the same time and refuse to give up a second basin.
The catch: those sharp 90-degree corners trade cleaning ease for a sleeker look, so keep a small brush within reach.
5. Ruvati RVH8300
A 32-inch single-tier workstation with a 10-inch bowl, a wood board, and a colander in the box.
With a 32-inch width, 19-inch front-to-back, and 10-inch bowl depth, this one sits in the most standard size the category makes. It uses 16-gauge T-304 stainless with a brushed finish that hides scratches, and the single-tier ledge takes a solid wood cutting board, a deep colander, and a roll-up drying rack. The interior bowl measures 30-1/2 by 16 inches, and a 36-inch minimum cabinet is required. The 3.5-inch drain opening fits any standard garbage disposal.
Owners describe the feel as cavernous compared with a split sink, and the appearance draws compliments from installers as much as guests. The included wood board, colander, bottom rinse grid, and basket strainer add up to a working station right from the start. The honest caveat is the bottom: a nearly flat slope means particles do not rush to the drain, and you should expect to wipe the bowl down after each use to keep the brushed surface bright.
Where it wins: 16-gauge steel with a brushed finish that hides scratches, plus a colander and wood board in the box, makes the value hard to argue with.
Pick it if: you want a mainstream 32-inch workstation with a proven steel pedigree and a 36-inch cabinet.
Know this first: the near-flat base means daily wiping, and some find the colander too bulky to share the ledge with a cutting board.
6. Elkay EFRU30169RTWC Workstation Sink, 31-1/2″, 16 Gauge
A 31-1/2-inch bowl with straight sidewalls and an offset drain, fitting a 30-inch cabinet.
The Elkay measures 31-1/2 inches across and 18-1/2 front-to-back with a 9-inch depth, so it sets into a 30-inch base cabinet — the smallest minimum in the stainless workstation group. The straight sidewalls and flat bottom give it a geometric profile with more usable floor area than a rounded bowl lets on. Premium 16-gauge Type 304 steel and sound pads with undercoating keep the noise down, and the offset drain leaves more usable floor space inside the bowl and more cabinet room below.
The sink quality and the look are what people praise most, and the tight corner design is the reason it reads as a modern fixture rather than a utility basin. The trade-offs are real but manageable: several owners note rust marks developing on the surface, and the low drain slope means you will be pushing food toward the drain rather than watching it flow. A bottom grid adds protection but makes wiping around it harder.
A fitting advantage: at 31-1/2 inches, this is nearly a half-inch narrower than the 32-inch KRAUS and Dcolora sinks, and it needs only a 30-inch cabinet instead of 36 — a genuine win for tight kitchens.
Suits you when: you have a 30-inch cabinet and want a sharp-cornered modern look with a reputable name on the steel.
Worth weighing: reports of surface rust and a fussy drain slope make this a hands-on sink, not a wipe-and-forget one.
7. KRAUS KGUW1-33WH
A quartz-composite bowl rated heat safe to 500°F, with a cutting board and roll-up rack included.
Composite is a different animal from stainless, and it earns its place here. The 32 by 19-inch sink with a 10-inch depth is built from quartz composite that resists impact and thermal shock, and it handles heat up to 500°F. That means a hot pan can land in the bowl without a warped or scorched surface. It carries the same integrated ledge for accessories and ships with a heavy-duty cutting board, a roll-up drying rack, and a drain assembly with strainer. The bowl measures 30 by 16 inches with a 9-3/8-inch depth, and the base cabinet needs 36 inches.
Owners are quick to point out the surface quality and the look, and the composite face gives the kitchen a softer, stone-like finish that quartz counters especially like. The rear-set drain and gently sloped base are designed to stop pooling and keep stemware from tipping. The split is on upkeep: dark surfaces can show water spots and lighter models show staining if tea, juice, or tomato sauce sits for hours, and a few reports mention cracking over time. Keep a spare sponge nearby and treat stains quickly.
The composite advantage
- Quartz composite resists impact and thermal shock up to 500°F
- Integrated ledge with cutting board and roll-up rack included
- Rear-offset drain with tune slope helps prevent pooling
- Lifetime warranty from Kraus
What to sign up for
- Light-colored composite needs prompt stain handling — tea and dark sauces are the enemy
- A few reports of cracking over time
- Drain color doesn’t match the bowl exactly on some finishes
A strong pick for: a white or light kitchen where stainless feels cold and you want stone-look warmth.
The real cost: composite rewards fast cleanup, and the white face will show every forgotten tomato-sauce drip.
8. KOHLER Task
A 33-inch bowl that installs top-mount or undermount, for counters that are already cut.
Kohler built this so you can go top-mount or undermount, which is unusually flexible if your countertop already has a hole in it. The bowl is 33 inches wide and 19 inches front-to-back, with a 9-inch depth and a 36-inch minimum cabinet. The 18-gauge stainless is a step thinner than the 16-gauge crowd, but the tightly angled fabricated corners make the most of the bowl space. A two-piece nesting colander set and a bamboo cutting board with silicone bumpers come in the box.
Functionality and appearance are the two things owners like most, and the 9-inch depth keeps the bowl comfortable to reach into. The offset drain leaves room in the cabinet below. The honest catch, and it shows up often enough to plan around: rust spots and water marks are recurring complaints, and the unpolished finish shows every splash without a wipe-down.
Where the flexibility pays off: top-mount or undermount installation is a genuinely rare option at this size and solves a real countertop problem.
The right call when: your counter is already cut or you want the top-mount option, and a 33-inch bowl with a 36-inch cabinet is the target.
Consider the steel: at 18-gauge it is thinner than the 16-gauge picks here, and the finish demands wiping to keep water marks away.
9. Strictly Sinks 32″ Copper
A brushed copper-tone finish over 16-gauge T-304 steel, sized for a 30-inch cabinet.
Most of this list is silver. This one is copper-tone, and that changes how the kitchen reads more than any spec sheet explains. The build underneath is serious: 16-gauge T-304 stainless steel, a 32 by 19-1/2-inch footprint, a 10-inch bowl depth, and a 30-inch minimum cabinet. An extra-thick sound-dampening pad wraps all sides, and an X-shaped channel groove in the base keeps water from pooling. The square drain and the bottom grid complete the package, alongside a wooden cutting board and colander.
Owners who have lived with it describe it as a statement piece with the steel to back it up, and the finish holds up without leaks or noise. The design also gets the less glamorous details right — the accessory set and the installation are clean. The upkeep is the part to know: the finish wants a microfiber dry-down after use, and heavy metal brushes or overloaded bowls are out. The provided care guidance is specific about avoiding hard brushes and long-soak messes.
The look is the point: brushed copper over 16-gauge T-304 steel differentiates this from every stainless option in the lineup.
Room to breathe: a 30-inch minimum cabinet means this 32-inch bowl fits smaller kitchen runs than most of the group.
Built for: a designer kitchen where the sink is the visual anchor and you don’t mind a drying ritual.
Care note: dry with a microfiber cloth and skip the metal scouring pads, or the brushed copper tone will lose its edge.
10. Sarlai 33 Kitchen Sink Undermount 33 x 19 Inch Workstation
A 33-inch single bowl with a 31-inch interior, sized for a 36-inch cabinet.
Thirty-three inches wide, 19 front-to-back, and 10 inches deep puts this basin at the generous end of the standard range. The interior measures 31 by 15.82 inches, and the whole thing needs a 36-inch minimum cabinet. The 16-gauge T-304 steel has a commercial brushed finish that hides scratches, and the front and back ledges hold the included cutting board, colander, drain assembly, roll-up rack, and bottom rinse grid.
The look and the quality are what keep owners happy, and the wide bowl is a hit with anyone who has ever wrestled a roasting pan into a small sink. The bottom slope and X-channel groove are there to move water quickly. The downsides that show up consistently are the ones to plan for: rust resistance and drainage are the two weak spots, and the rail-based accessories need regular care to stay useful. It is a good fit if you prioritize bowl size and finish over perfect flow.
The case for the wide basin
- 31 x 15.82-inch interior bowl takes large cookware flat
- Full accessory kit — cutting board, colander, rack, grid, drain
- 16-gauge T-304 steel with a scratch-hiding brushed finish
- Ledges on both sides for sliding accessories
Check before you commit
- Rust resistance is a repeated concern over time
- Drainage receives negative feedback — expect to help food along
- Limited three-month return window with a limited lifetime warranty
Go for it when: bowl width is the top priority and a 36-inch cabinet is available for a 33-inch sink.
Weigh this: the drain slope and surface rust reports mean you should plan to dry the bowl after use.
11. Kichae 32 Workstation
A full workstation kit that asks for less counter space than most.
The 32 by 19-inch body with a 9-inch depth is a touch shallower than the 10-inch bowls here, and that makes reaching the bottom easier for shorter users. It needs a 35-inch minimum base cabinet, which is a slightly friendlier number than the usual 36. The 16-gauge T-304 stainless has a commercial satin finish for corrosion and rust resistance, and the 10R rounded corners help with wiping. The package is thorough: cutting board, colander, roll-up drying rack, basket strainer, bottom grid, and mounting hardware.
Owners tend to praise the deep workstation design and the heavy-duty build, and the value story is the accessories — most of what you need is already in the box. The offset center drain and X-groove base are designed to keep water from pooling. The scratch question is the one to keep in mind: the surface is reported to scratch more easily than some competitors, so use the bottom grid and avoid scouring pads.
Steel for the money: 16-gauge T-304 steel with a sunken ledge and a full accessory set is the definition of value in this category.
Choose this if: you want a complete workstation setup, a 35-inch cabinet, and a slightly shallower bowl for easy reach.
Worth knowing: the finish is prone to scratching, so the included bottom grid is not optional — leave it in.
12. BoomHoze 30 x 19
A 30-inch single bowl with a 10-inch depth, fitting a 33-inch cabinet.
Not every kitchen can host a 33-inch bowl, and this one sidesteps that problem with a 30 by 19-inch footprint and a 10-inch depth. It needs a 33-inch minimum cabinet, the smallest requirement among the stainless single bowls here. The 16-gauge SUS304 steel carries a brushed nickel finish for scratch and stain resistance, and the package includes a solid wood cutting board, a stainless colander, a roll-up dish drying rack, a 3.5-inch basket strainer, and a bottom rinse grid.
Owners lean on the looks here — the appearance and the value are the two things that come up most, and the deep single basin handles a full sink of dishes. The X-shaped water guideline in the base is designed to drain quickly and reduce splashing. Durability gets a split reaction, with some reporting a solid build and others hitting issues, so treat this as a well-priced fit for a tighter cabinet rather than a lifetime heirloom.
Where the smaller size pays off
- 30 x 19-inch footprint needs only a 33-inch cabinet
- 10-inch depth holds a full load of dishes
- Factory kit includes board, colander, rack, strainer, and grid
- 16-gauge SUS304 with a brushed nickel finish
Things to keep in mind
- Durability feedback is mixed
- Smaller bowl means less room for oversized pans
- No offset drain option
Step this way if: your cabinet tops out at 33 inches and you still want a deep single-bowl workstation.
Trade-off to accept: a 30-inch bowl is roomy for daily dish duty but tight for a full-size roasting pan.
13. DC-U7744
Rounded R10 corners that cut down the scrubbing, in a straightforward workstation body.
This Dcolora sink is 32 inches wide and 19 inches front-to-back with a 10-inch depth, and it needs a 30-inch minimum base cabinet — the same compact requirement as the Elkay and Strictly Sinks models. The brushed stainless finish hides everyday water marks and fingerprints better than a polished bowl, and the R10 corner radius (a rounded, not sharp, inside corner) gives you a surface you can wipe in one pass instead of digging into a corner seam. Sound-deadening pads and an anti-condensation coating keep the clatter down and protect the cabinet base underneath.
The ledge runs front and back for sliding accessories, and the box arrives with a bottom grid, colander, cutting board, and drying rack — a complete station rather than a sink plus upsells. The honest notes to weigh: 34 pounds makes this a two-person lift during install, and it is a heavier piece than the 26.5-pound KRAUS above. Feedback on this newer model is still building, so the strongest signals come from the build itself — 16-gauge stainless, a soundproofed body, and a full accessory set.
What the R10 corners buy you: rounded inside corners are the difference between one swipe and a bottle brush, and that matters every single night.
The smart fit if: you have a 30-inch cabinet and a rounded corner feels like the right trade for daily cleanup.
Also consider: the accessory kit is generous, but confirm what your particular unit ships with before you plan around it.
14. HOTIS 32″ x 18″
An 18-inch-deep bowl that trades a little front-to-back room for a tighter cutout.
Most sinks here measure 19 inches front-to-back. This HOTIS runs 18 inches, and that 1-inch difference is the whole story — it is a smaller cutout to work with, and the 32-inch width stays the same. The width comparison is the striking one: the Dcolora above has three mounting holes to this sink’s one, so check your faucet and soap dispenser plan before you commit. The 16-gauge SUS304 steel has a brushed nickel finish, and the kit bundles a cutting board, colander, stretchable roll-up drying rack, bottom rinse grid, and strainer.
The single-track ledge runs front and back for sliding accessories, and the heavy paint undercoating with thick rubber pads is there to dampen noise and block condensation. The X-guideline base and bottom grid are designed to drain fast and shield the surface from scratches. What to keep in mind is the fit: this is a genuinely compact bowl, and a handful of owners mention the underside mounting tabs needed modification for certain install styles, so dry-fit it against your cutout plan before cutting.
The depth side of the trade: at 9 inches this bowl is a full inch shallower than the 10-inch KRAUS and Ruvati bowls — a real plus if reaching the bottom of a deep sink is a stretch.
Consider it when: you want a 32-inch workstation with a shallower bowl and a compact front-to-back footprint.
Measure before you cut: the mounting tabs sit on the underside, so confirm your installation style and cutout template before anything gets removed.
Know the Specs
Gauge — the thickness number
Gauge is a metal thickness rating, and confusingly, a lower number means thicker steel. A 16-gauge sink is the sturdier mainstream choice: it feels solid under a full pot and mutes the clatter of dropped spoons. An 18-gauge bowl is thinner, so it relies more on sound pads to stay quiet. Thicker steel also resists dents from a dropped pan. When you see “TRU16” or “T-304,” the first is the maker’s thickness label and the second is the stainless grade — a standard blend that resists rust and staining.
Minimum base cabinet width
This is the smallest kitchen cabinet box the sink can physically sit over, measured inside the cabinet frame. A 30-inch sink often needs a 30-inch or 33-inch cabinet; a 32-inch usually wants 35 or 36 inches; a 45-inch needs 48. Get this wrong and the sink will not clear the cabinet walls, no matter how carefully the countertop is cut. Measure the inside of the box, not the old sink opening, and add room for the mounting clips.
Bowl depth and what it holds
A 10-inch bowl lets a stock pot or a baking sheet stand upright, and the extra wall height contains splashes. A 9-inch bowl is easier to reach into, which helps shorter users or anyone who does not want to bend over the counter. Depth also changes how the sink sounds and how much water it takes to fill for soaking. Match the number to the tallest thing you routinely wash.
Corner radius and drain slope
An R10 corner is a rounded inside corner with a small radius — a compromise between the sleek look of sharp 90-degree corners and the easy wiping of a fully curved bowl. Rounded corners clean faster; sharp corners look more architectural and catch more debris. The drain slope is its partner: a gentle slope with channel grooves moves water and food to the drain, while a nearly flat base leaves you pushing debris across the bowl with a sponge.
Common Questions
Will a 32-inch undermount workstation sink fit my existing cabinet?
What does 16 gauge mean and does it really matter?
Can I install an undermount workstation sink in a countertop that is already cut?
Do these sinks work with a garbage disposal?
Why do water marks appear on brushed stainless and how do I stop them?
Is a rounded corner sink easier to clean than a sharp corner one?
Can a granite composite sink handle a hot pan?
Does an offset drain actually free up cabinet space?
How deep should the bowl be for a large stock pot?
Is a workstation sink with accessories worth the extra moving parts?
The Bottom Line
For most kitchens, the undermount workstation sinks winner is the KRAUS KWU110-32 because its 16-gauge steel, 10-inch bowl, and complete 5-piece kit cover prep, washing, and drying in one station. If you want the largest basin and a two-tier ledge for entertaining, the Delta Lorelai 45-inch is the one to reach for. And for a tigh
