A 28-inch undermount stainless steel sink can give you a roomy single bowl without taking over the whole counter, but the right choice depends on more than its outside width. Bowl depth, cabinet fit, steel thickness, included accessories, and the countertop cutout all matter. These five options range from a straightforward sink with a basic kit to workstation models with sliding accessories, so you can compare the features that best match your kitchen and daily routine.

Our Picks: Best 28 Inch Undermount Stainless Steel Sink reviews
1. MAYESAR: A Well-Equipped 16-Gauge Sink for Everyday Use
The MAYESAR is a single-bowl undermount sink with a 28-by-18-inch exterior and a 9-inch depth. Its 16-gauge SUS 304 stainless steel construction and brushed finish make it a solid fit for a kitchen that needs a practical, uncluttered basin rather than an integrated workstation.
Inside, the bowl measures 26 by 16 inches, giving you room for larger cookware while keeping the overall sink size compact. The listing describes a gently sloped bottom with X-shaped grooves to guide water toward the drain. R10 rounded corners are designed to make wiping the basin easier, while sound-dampening pads and an anti-condensation coating address noise and moisture beneath the sink.
The package includes a bottom grid, towel, drain assembly, and guide. That is a useful set of basics, though it does not include the sliding prep accessories found with the SANYCASA and Lordear workstation models. Check your cabinet carefully: this sink calls for a minimum 31-inch cabinet.
Pros:
- 16-gauge SUS 304 construction
- Brushed finish and stated anti-stain coating
- Includes a bottom grid and drain assembly
- 9-inch-deep bowl with a standard 3.5-inch drain opening
Cons:
- Requires a minimum 31-inch cabinet
- No workstation track or prep accessories are listed
Verdict: Choose the MAYESAR if you want a conventional, well-equipped 28-by-18-inch sink with a bottom grid and do not need workstation features.
2. SANYCASA: A Thick-Gauge Workstation with a Deep Bowl
The SANYCASA is a 28-by-19-by-10-inch undermount workstation sink. Its defining feature is a single-tier track that lets you use compatible accessories across the bowl, helping move some meal-prep and drying tasks off the countertop. The package is described as including a cutting board, colander, roll-up drying rack, bottom rinse grid, and strainer, among other items.
This model is made from SUS 304 stainless steel, and the listing specifies an 11-gauge edge with a thickness of 3 mm. That is a heavier-gauge construction than the 16-gauge options in this guide. It also has R10 corners, sound-dampening silicone pads, an anti-condensation coating, and a sloped, grooved basin intended to promote drainage.
The deeper 10-inch bowl can be useful when you wash large pots or want more room for stacked dishes. However, the listing does not provide a minimum cabinet size, so confirm the cabinet, sink cutout, and plumbing clearances with the installation requirements before buying. Its accessory track is most useful if you expect to use the included pieces; if you prefer an open, simple basin, a standard sink may be a better match.
Pros:
- 11-gauge SUS 304 construction with a stated 3 mm edge
- 10-inch depth and workstation track
- Includes several prep, rinsing, and drying accessories
- Sound-dampening pads and anti-condensation coating
Cons:
- Minimum cabinet size is not specified in the supplied details
- The workstation accessories may be unnecessary if you want a basic sink
Verdict: The SANYCASA is a strong choice if you want a deep workstation sink and value its heavier-gauge steel and bundled accessories.
3. Delironexu: A 16-Gauge Sink with a Practical Accessory Kit
The Delironexu is a 28-by-18-by-9-inch single-bowl sink made from 16-gauge 304 stainless steel. Its interior dimensions are listed as 26 by 16 inches, and the brushed finish gives it a straightforward look that can suit a range of kitchen styles. As an undermount model, it is designed to sit below the counter edge for a continuous surface around the basin.
The basin has a sloped bottom and X-shaped grooves to guide water toward the drain. The listing also specifies R10 corners, sound-dampening pads covering more than 80% of the sink base and walls, and a full-cover anti-condensation coating. Those details make this option notable if you are comparing how the sink may manage noise and moisture, though they do not remove the need to keep the cabinet area dry and properly installed.
Its package includes a bottom grid, roll-up drying rack, drain assembly, towel, mounting hardware, and cutout template. The template may be useful during planning, but you should still confirm the dimensions and countertop requirements with your installer. The brand states that long-term protection covers manufacturing defects, excluding accessories.
Pros:
- 16-gauge 304 stainless steel
- Includes a grid, roll-up rack, drain assembly, and cutout template
- Sound-dampening pads cover more than 80% of the base and walls
- Standard 3.5-inch drain opening
Cons:
- At 9 inches deep, it is shallower than the 10-inch workstation options
- Stated long-term protection excludes accessories
Verdict: Consider the Delironexu if you want a conventional 16-gauge sink with a useful mix of installation, rinsing, and drying accessories.
4. Ufaucet: A Simple 28-by-18-Inch Sink with a Clean Look
The Ufaucet is a 28-by-18-inch undermount sink with a 9-inch-deep single bowl. The listing gives interior dimensions of 26 by 16 inches and describes the finish as brushed nickel stainless steel. Its simple basin design may appeal if you want the seamless look of an undermount sink without a built-in workstation rail.
The sink is listed as 16 gauge and has an X-shaped groove pattern with a slight bottom slope to help direct water toward the drain. R10 corners are intended to make the basin easier to wipe. The package contents are more basic than those of the other choices: the supplied details list the sink and a drain strainer, but do not list a bottom grid, rack, or prep accessories.
The 3.5-inch drain opening is described as compatible with most common garbage disposals. Still, check your disposal and plumbing setup before ordering, and confirm the cabinet and countertop cutout dimensions with your installer. The listing does not provide a minimum cabinet size, so avoid assuming it will fit a particular base cabinet based on the outside sink width alone.
Pros:
- 16-gauge construction and 9-inch bowl depth
- Standard 3.5-inch drain opening
- Sloped, grooved bottom and R10 corners
Cons:
- Only a drain strainer is listed as an included accessory
- Minimum cabinet size is not specified in the supplied details
Verdict: The Ufaucet makes sense if you want a straightforward 28-by-18-inch sink and do not need a broad accessory package.
5. Lordear: A Workstation Sink with Sliding Prep Accessories
The Lordear is a 28-by-19-by-10-inch workstation sink made from 16-gauge T304 stainless steel. Its front and back ledges form a track for sliding accessories, letting you use the sink area for tasks such as prep and drying. This setup can help keep accessories over the basin rather than occupying as much counter space.
The package is described as including a cutting board, colander, roll-up rack, bottom rinse grids, basket strainer drain, cutout template, mounting clips, and installation instructions. Its X-shaped water guide and sloped drain area are designed to move water toward the drain. The extra depth and accessory track set it apart from the simpler 9-inch-deep sinks in this group.
Plan around the listed minimum 31-inch cabinet base size. A workstation track can add useful flexibility, but it is a less compelling feature if you do not expect to use the accessories. As with any undermount sink, confirm the countertop material, cutout, mounting method, and plumbing details before installation.
Pros:
- 16-gauge T304 stainless steel
- 10-inch depth and sliding workstation track
- Includes several prep, drying, and rinsing accessories
- Minimum cabinet size is stated as 31 inches
Cons:
- Requires a minimum 31-inch cabinet base
- Workstation accessories may be more than you need for basic sink use
Verdict: Pick the Lordear if you want a deep workstation sink with a large accessory set and have a cabinet that meets its stated minimum size.
How to Choose a 28-Inch Undermount Stainless Steel Sink
Measure the Cabinet and Countertop Cutout
Do not rely on the “28-inch” label alone. Check the sink’s outside dimensions, bowl dimensions, cabinet base width, and the countertop cutout requirements. MAYESAR and Lordear specify a minimum 31-inch cabinet; the supplied details for the other models do not state one. If you are replacing a sink, compare the new sink’s shape and mounting needs with the existing cutout before ordering.
Choose Bowl Depth for Your Kitchen Habits
The sinks in this guide range from 9 to 10 inches deep. A deeper bowl can give you more room for large cookware and stacked dishes, but it may also affect how comfortably you reach the bottom. Consider the people who will use the sink and the kinds of items you wash most often, then compare both exterior depth and interior dimensions.
Understand the Steel Gauge and Type
Gauge is a measure of steel thickness; a lower gauge number indicates thicker steel. The SANYCASA is listed as 11 gauge, while the MAYESAR, Delironexu, Ufaucet, and Lordear are listed as 16 gauge. Some listings also identify the steel as SUS 304 or T304. Compare the stated construction, but also consider the sink’s finish, sound-dampening features, and package contents.
Decide Whether a Workstation Track Is Worth It
The SANYCASA and Lordear have ledges or a track for sliding accessories. Their included pieces can support prep, rinsing, or drying at the sink, which may help when counter space is limited. If you mainly need a basin for washing dishes, the simpler MAYESAR, Delironexu, or Ufaucet designs may suit you better.
Compare the Included Accessories
Included items vary. MAYESAR lists a bottom grid, towel, and drain assembly; Delironexu includes a grid, rack, drain assembly, towel, and installation items; Ufaucet lists a drain strainer. SANYCASA and Lordear bundle workstation accessories. Confirm exactly what comes with the sink and whether you will need to purchase any additional drain, mounting, or protection components separately.
Look at Drainage and Basin Details
Each listing describes a sloped basin, grooves, or both to help move water toward the drain. Rounded R10 corners are also listed on several models. These features can support easier wiping and drainage, but they do not replace regular cleaning. Check the drain opening size and make sure it works with your drain assembly or garbage disposal.
Plan for Installation and Cabinet Protection
Undermount sinks need a secure connection below the countertop, so check that the sink is appropriate for your counter and installation plan. Review the included mounting hardware and template, if provided, and confirm who will handle the cutout and mounting. Sound-dampening pads and anti-condensation coatings are described on some models, but careful installation and attention to leaks remain important for protecting the cabinet.
Frequently Asked Questions
Will a 28-inch sink fit a 30-inch cabinet?
It depends on the sink’s exact dimensions and the cabinet’s usable interior space. MAYESAR and Lordear specify a minimum 31-inch cabinet base, so those models should not be assumed to fit a 30-inch cabinet. Check the manufacturer’s installation requirements and consult your installer before choosing another model with no listed minimum.
Is 11-gauge steel thicker than 16-gauge steel?
Yes. For steel gauge, a lower number means thicker material. The SANYCASA is listed as 11 gauge, while the other sinks in this guide are listed as 16 gauge.
What is the benefit of an undermount sink?
An undermount sink sits below the countertop edge, creating a continuous surface around the basin. This can make it easier to wipe crumbs and water from the counter into the sink. The counter material and installation method must be suitable for an undermount setup.
Do these sinks include a garbage disposal?
The supplied product details do not list a garbage disposal as included. Several sinks have a standard 3.5-inch drain opening, which the listings describe as compatible with most common disposals. Confirm compatibility with your specific disposal and drain parts.
Should I choose a 9-inch or 10-inch bowl?
A 10-inch bowl offers more depth for larger cookware, while a 9-inch bowl may be enough for everyday dishes and can be easier to reach into. Think about what you wash most and compare the interior bowl measurements as well as the stated depth.
Are the workstation accessories necessary?
No. They are optional features that may help if you want to prep, rinse, or dry items over the sink. If you prefer a simple basin or already have enough counter space, a standard single-bowl model may be a better fit.
Final Recommendation
For a conventional 28-by-18-inch sink with a useful basic kit, the MAYESAR is a well-rounded option, while the Delironexu adds a roll-up rack and installation accessories. If you want a workstation setup, compare the deeper SANYCASA and Lordear; the SANYCASA stands out for its listed 11-gauge construction, while the Lordear clearly states a 31-inch minimum cabinet size. Before choosing any model, verify your cabinet, countertop cutout, and drain requirements.
