A 16-gauge undermount sink can give your kitchen a sturdy, easy-to-clean work area with a clean edge where the sink meets the countertop. The right choice depends on more than steel thickness: check the cabinet and bowl dimensions, decide whether you want a simple basin or a workstation ledge, and consider which accessories come in the box. These five options include both straightforward single-bowl sinks and models designed to add prep and drying space.

Our Picks: Best Undermount Stainless Steel Sinks 16 Gauge reviews
1. Kraus KHU100-32: A straightforward, roomy single bowl
The Kraus KHU100-32 is a practical pick if you want a deep, open basin without a workstation ledge. Its exterior measures 32 by 19 inches, and the bowl is 30 by 17 inches with a 10-inch depth. Kraus recommends a cabinet at least 36 inches wide, so measure the space carefully before planning a countertop cutout.
The sink is made from 16-gauge T-304 stainless steel and has a satin finish. Tightly rounded corners keep the look simple while helping make the basin easier to clean. A sloped bottom and channel grooves are designed to guide water toward the drain. The included bottom grid helps protect the sink floor, and the package also lists a drain assembly with strainer, mounting hardware, a template, and a kitchen towel.
Compared with the workstation models below, this sink offers fewer built-in tasks and accessories, but its open basin may suit you better if you mainly wash dishes, cookware, and produce. One tradeoff is its large single-bowl format: there is no separate basin for keeping clean items apart from dirty dishes.
Pros:
- Durable 16-gauge T-304 stainless steel construction
- Deep, wide bowl accommodates larger cookware
- Bottom grid and drain assembly are included
- Sloped base and channel grooves are designed to help water drain
Cons:
- Requires a cabinet at least 36 inches wide
- No integrated workstation ledge or prep accessories
Verdict: Choose the KHU100-32 if you want a roomy, no-frills undermount sink with a protective grid and a clearly specified accessory package.
2. Oxwiser 32 × 18-Inch Sink: A bundled option with sound-dampening features
This Oxwiser single-bowl sink measures 32 by 18 inches overall, with a 30-by-16-inch interior and a 9-inch bowl depth. Its 16-gauge T-304 stainless steel construction and brushed finish are aimed at everyday kitchen use. Like the other 32-inch picks here, it calls for a minimum 36-inch cabinet.
The package is described as a five-item bundle: it includes mounting hardware, a stainless steel bottom grid, a three-piece basket strainer waste, and a kitchen towel alongside the sink. Soundproofing pads are fitted to the bottom, and an undercoating is intended to help limit condensation. The X-groove design is meant to support drainage, while the standard 3.5-inch drain opening is specified to fit a garbage disposal unit.
Its 18-inch exterior width makes it slightly narrower front to back than the 19-inch options, which may matter in a tighter countertop layout. The bowl is also shallower than several alternatives in this selection. Check your preferred faucet, drain, and disposal setup before installation, and confirm the included hardware works with your countertop and cabinet.
Pros:
- 16-gauge T-304 stainless steel construction
- Includes a bottom grid, strainer components, and towel
- Soundproofing pads and undercoating are specified
- Standard 3.5-inch drain opening is designed for garbage disposal compatibility
Cons:
- 9-inch bowl is shallower than the 10-inch bowls in several competing picks
- Requires a cabinet at least 36 inches wide
Verdict: Consider the Oxwiser if you want a 16-gauge sink with a useful accessory bundle and sound-dampening features, and its 9-inch bowl depth suits your needs.
3. Sarlai 33-Inch Workstation: Built-in room for prep and drying
The Sarlai is a 33-by-19-inch single-bowl workstation sink made from 16-gauge T-304 stainless steel. Its interior measures 31 by 15.82 inches, and the bowl is 10 inches deep. Despite its 33-inch exterior width, the stated minimum cabinet size is 36 inches, so use the supplied dimensions—not just the product name—to check fit.
Ledges along the front and back create tracks for accessories, letting you shift between sink and prep tasks. The package includes a cutting board, stainless steel colander, drain assembly, roll-up rack, and bottom rinse grid. A brushed finish, rounded corners, bottom slope, and X-shaped drainage guide are intended to support daily use and cleanup. The listing also describes a heavy undercoating and thick rubber pads for sound dampening and condensation protection.
This model provides more included workstation pieces than the basic Kraus KHU100-32, but accessories that rest or slide on ledges take up room when in use and may need to be moved aside for larger pots. Its 15.82-inch interior width is also worth checking against your largest cookware. If you prefer an open basin with fewer components to store, a standard sink may be a better fit.
Pros:
- Workstation ledges help add prep and drying space
- Includes a cutting board, colander, roll-up rack, and bottom grid
- 10-inch-deep bowl and 16-gauge T-304 stainless steel
- Sound-dampening pads and undercoating are specified
Cons:
- Workstation accessories may need to be removed to open up the basin
- Confirm that the 31-by-15.82-inch interior suits your cookware
Verdict: Pick the Sarlai if you want a larger workstation-style sink with several prep and drying accessories included.
4. Kraus KWU110-32: A workstation sink with a 10-inch bowl
The Kraus KWU110-32 combines a 32-by-19-inch exterior with an integrated ledge for sliding accessories. Its bowl measures 30 by 16 inches and is 10 inches deep; the stated minimum cabinet width is 36 inches. This design lets you prep or dry dishes over the sink rather than relying only on the surrounding counter.
The package includes a cutting board, roll-up dish rack, protective bottom grid, drain assembly with cover, mounting hardware, and a template. It is made from 16-gauge TRU16 stainless steel and has a satin finish. Rounded bottom corners and a sloped base with channel grooves are designed to help with cleaning and drainage.
Compared with the non-workstation KHU100-32, the KWU110-32 trades some open-basin simplicity for more ways to use the sink area. Its 16-inch interior width is narrower than the KHU100-32’s 17-inch bowl, so compare the interior dimensions if you often wash wide pans. The included accessories add convenience, but you will need somewhere to keep them when they are not in use.
Pros:
- Integrated ledge supports over-sink prep and drying
- Includes a cutting board, roll-up rack, and bottom grid
- 10-inch-deep bowl with 16-gauge stainless steel construction
- Sloped bottom and channel grooves are designed to guide drainage
Cons:
- Interior bowl is narrower than the Kraus KHU100-32
- Workstation accessories require storage when not in use
Verdict: Choose the KWU110-32 if you want a familiar Kraus 16-gauge build with an integrated ledge and useful prep accessories.
5. Ruvati RVH8300: A flexible workstation with soundproof undercoating
The Ruvati RVH8300 is a 32-by-19-inch undermount workstation sink with a 30.5-by-16-inch interior and a 10-inch bowl depth. It calls for a 36-inch minimum base cabinet. Its single-tier ledge is designed for sliding accessories, including the supplied solid wood cutting board, deep stainless steel colander, and roll-up drying rack.
The sink uses 16-gauge T-304 stainless steel with a commercial-grade brushed finish. Heavy-duty rubber padding and a soundproof undercoating are intended to reduce noise and condensation. The sloped bottom and drain grooves are designed to move water toward the drain, and the standard 3.5-inch drain is specified to fit a garbage disposal. The package also includes a bottom rinse grid, basket strainer drain, and mounting clips; the sink is listed as CUPC certified.
The Ruvati has a sleek, sharp-cornered look, unlike the more rounded corners on several other picks. That style may appeal if you want a crisp modern design, though tight corners can take more attention during cleaning. Its bowl dimensions are close to the Kraus KWU110-32, but its accessory set includes a colander, making it a useful option if you want to work over the sink.
Pros:
- Workstation ledge and several accessories support prep and drying
- 16-gauge T-304 stainless steel with soundproof undercoating and rubber padding
- 10-inch bowl with a standard 3.5-inch drain opening
- CUPC certification is specified
Cons:
- Sharp corners may take more care to clean than rounded-corner designs
- Requires a minimum 36-inch base cabinet
Verdict: The RVH8300 is a strong fit if you want a workstation sink with a colander and drying rack, and you prefer its sharper-cornered design.
How to Choose a 16-Gauge Undermount Stainless Steel Sink
Measure the cabinet and countertop opening
Start with the sink’s exterior dimensions and the manufacturer’s minimum cabinet size. All five picks specify a 36-inch minimum cabinet, but their exterior widths and bowl sizes differ. Also check the countertop cutout and the space below the sink for plumbing and disposal equipment. For an undermount installation, coordinate the sink dimensions and cutout with your countertop installer before ordering.
Compare the bowl’s interior dimensions and depth
Exterior measurements do not tell you how much usable basin space you will have. Compare interior length and width against the pots, pans, and baking sheets you wash most often. Bowl depths in this group range from 9 to 10 inches. A deeper bowl can provide more room for dishes, but make sure its depth works with your cabinet and your preferred faucet setup.
Decide whether you want a workstation ledge
A workstation sink has a ledge or track that supports accessories such as a cutting board, colander, or drying rack. This can add prep space over the basin, especially when counter space is limited. It also means accessories may need to be shifted or stored to leave the full bowl open. If you mainly want a simple wash basin, the Kraus KHU100-32 keeps the design more straightforward.
Look at steel gauge, grade, and finish
Each pick is described as 16-gauge stainless steel, and several specify T-304 steel. Gauge refers to sheet thickness; within this group, the shared 16-gauge specification makes dimensions, finish, design, and included features important points of comparison. A brushed or satin finish can affect the sink’s look and how visible everyday marks are. Follow the manufacturer’s care guidance to keep the surface in good condition.
Check noise and condensation features
Running water and dishes can create noise in a metal basin. Some options here list rubber pads or soundproofing features, and some also describe an undercoating intended to help limit condensation beneath the sink. These details may matter if you want to reduce sound or protect the cabinet area. Compare the specific construction listed for each model rather than assuming all 16-gauge sinks include the same treatment.
Review the drain and included accessories
Check whether the sink comes with a drain assembly, strainer, mounting hardware, template, or bottom grid, and confirm what is included in the exact package you select. The drain opening and disposal compatibility also matter if you plan to use a garbage disposal. Workstation accessories vary by model, so check the listed pieces to see whether they match the way you cook and clean.
Plan for installation and upkeep
An undermount sink sits beneath the countertop, creating a smooth transition from counter to basin. This makes it possible to wipe crumbs and water into the sink, but proper support and a suitable countertop opening are essential. Confirm installation requirements with your contractor or installer. For day-to-day care, use cleaning methods appropriate for stainless steel and pay attention to the corners, drain area, and accessory tracks.
Frequently Asked Questions
What does 16-gauge mean for a stainless steel sink?
Gauge is a way to describe the thickness of sheet metal. These picks are all listed as 16-gauge sinks. Since that specification is shared, also compare each model’s dimensions, steel grade, finish, noise-control features, and included accessories.
What cabinet size do these sinks need?
All five listings specify a minimum cabinet width of 36 inches. Check the sink’s full dimensions and installation requirements as well, since the cabinet opening, plumbing, and countertop cutout must all work together.
Are these sinks compatible with a garbage disposal?
The Oxwiser and Ruvati listings specify a standard 3.5-inch drain opening designed to fit a garbage disposal. For the other models, confirm drain and disposal compatibility with the product details and your installer before purchase.
Is a workstation sink worth choosing?
A workstation sink can be useful if you want to prep food or dry dishes over the basin using a ledge and accessories. If you prefer a wide, open bowl with fewer pieces to move or store, a standard single-bowl sink may be more convenient.
Which sink has the deepest bowl?
The Kraus KHU100-32, Sarlai, Kraus KWU110-32, and Ruvati list 10-inch bowl depths. The Oxwiser lists a 9-inch bowl depth. Check the complete interior dimensions as well, since depth alone does not determine how much cookware fits.
What accessories are included with these sinks?
Accessories differ by model. The basic Kraus includes a bottom grid and drain assembly, while the workstation options list items such as cutting boards, roll-up racks, colanders, or strainers. Check the current product details to confirm the package contents before ordering.
Final Recommendation
For a simple, roomy basin, the Kraus KHU100-32 is the clearest all-around choice in this group, with a 10-inch bowl, bottom grid, and drain assembly. If you want to prep or dry dishes over the sink, compare the Kraus KWU110-32, Sarlai, and Ruvati workstation models by their bowl dimensions and included accessories. The Oxwiser is worth considering if its 9-inch depth and bundled sound-dampening features fit your plans. Before buying any of them, confirm the 36-inch cabinet requirement and coordinate the undermount cutout with your installer.
