A 40/60 stainless steel undermount sink gives you two bowls of different sizes for tasks like rinsing produce, soaking dishes, and washing cookware. The right choice depends on more than the bowl split: check the sink’s outside dimensions against your cabinet and countertop, compare bowl depth and divider design, and consider which accessories come in the box. These five options range from straightforward double-bowl designs to deeper or more feature-rich sinks.

Quikore 32-Inch Sink: A Practical Standard-Depth Double Bowl
The Quikore is a 32-inch undermount sink with a larger bowl, a smaller bowl, and 18-gauge 304 stainless steel construction. Its outside dimensions are 32-1/4 by 20-3/4 inches, and both bowls are 9 inches deep. The product information specifies a 35-inch minimum cabinet, so check that measurement against your cabinet before planning the installation.
Rounded bowl corners are intended to avoid hard-to-clean interior angles, while the sloped bottoms are designed to guide water toward the drains. Sound-absorbing pads and an exterior coating address noise and condensation. The sink has standard 3.5-inch drain openings, which the manufacturer says fit US garbage disposals; the supplied details do not say that a disposal or drain assembly is included.
This is a straightforward choice if you want a two-bowl layout without a deeper 10-inch basin or a workstation ledge. Its 18-gauge steel is not as thick as the 16-gauge material listed for the Lordear, PHS, and Ruvati options, and the listing describes a conventional divider rather than a low-divider design. That may matter if you often need to fit wide cookware across both bowls.
Pros:
- 304 stainless steel with an 18-gauge build
- Two 9-inch-deep bowls and rounded interior corners
- Sound-absorbing pads and exterior condensation coating
- 35-inch minimum cabinet requirement is specified
Cons:
- Not described as a low-divider or workstation sink
- Drain assemblies and other accessories are not listed as included
Verdict: Choose the Quikore if you want a clearly specified 32-inch, 18-gauge double bowl with noise-reduction features and your cabinet meets the stated minimum size.
KRAUS Premier: A 60/40 Sink with a Low Divider and Strainers
The KRAUS Premier pairs an 18-gauge stainless steel body with a 60/40 double-bowl layout and a low divider. The exterior measures 32 by 20-5/8 inches, with a 9-inch overall depth. Bowl dimensions differ: the larger bowl is listed at 8-1/2 inches deep, and the smaller at 6-1/2 inches. The product information calls for a minimum 36-inch cabinet.
A low divider can make it easier to handle larger items across the two bowls than a full-height divider, while still keeping separate spaces for washing and rinsing. The package is listed as including two drain assemblies with strainers, mounting hardware, and a template. Sound-reduction pads, full insulation, a gently sloped bottom, and rounded corners are also specified.
The larger cabinet requirement is worth noting: it is one inch more than the stated minimum for the Quikore and Lordear. The smaller bowl is also shallower than the large bowl, which may be useful for separate tasks but is less suited to soaking tall items. The supplied product data marks this model as unavailable, so check its listing status before making plans around it.
Pros:
- Low-divider 60/40 layout for handling larger cookware
- 18-gauge stainless steel with sound-reduction features
- Two strainers, hardware, and a template are listed as included
- Sloped bottom and rounded corners support drainage and cleaning
Cons:
- Requires a stated minimum 36-inch cabinet
- The smaller bowl is only 6-1/2 inches deep
Verdict: Consider the KRAUS if its low divider and included drain parts suit your needs, but verify that the listing is available and that your cabinet meets its 36-inch minimum.
PHS 33-Inch Sink: A 16-Gauge Option with Bottom Grids
The PHS is a 33-inch undermount sink made from 16-gauge stainless steel. Its listed exterior dimensions are 33 by 19 inches, with a 9-inch height. The included items are a pair of bottom grids, a basket strainer with lid, another strainer, a cutout template, and mounting clips. The listing specifies a standard 3.5-inch drain opening but does not provide a minimum cabinet size.
The product information highlights vibration-absorbing pads and a condensation-resistant coating, along with an X-shaped drainage pattern and sloped bottom. These details are intended to reduce sound and help water move toward the drain. The brushed finish and rounded corners are also designed to support easier cleaning.
Its listed 16-gauge construction is thicker than the 18-gauge steel in the Quikore and KRAUS options. The tradeoff is less complete fit information: the provided dimensions do not identify the bowl sizes, divider height, or required cabinet width. The data also marks this sink as unavailable, so check its current listing and installation details before choosing it.
Pros:
- 16-gauge stainless steel construction
- Two bottom grids and two strainer components are listed
- Sound-absorbing pads and condensation-resistant coating
- Sloped base and X-shaped drainage lines
Cons:
- Minimum cabinet size and individual bowl dimensions are not specified
- Supplied product information marks the listing as unavailable
Verdict: The PHS is worth considering if you value its 16-gauge body and included grids, provided you can confirm the fit and listing status before purchase.
Lordear 32-Inch Sink: A Deep Low-Divide Workstation Design
The Lordear combines a 60/40 double bowl with a low center divider and a workstation ledge. Its 16-gauge SUS304 stainless steel body measures 32 by 19 by 10 inches, and the product information recommends a minimum 35-inch base cabinet. A 3.5-inch drain opening is listed as compatible with most garbage disposal units.
The built-in track is designed to hold sliding workstation accessories, creating an extra food-prep area over the sink. That feature may be useful if you want to make more use of sink space, though the supplied details do not list which accessories come with the sink. Its low divide can also provide more room for wide cookware than a standard full divider. The 10-inch-deep bowls are deeper than the 9-inch models in this comparison.
The sloped basin and X-shaped guide lines are intended to direct water toward the drain, while full-coverage sound-deadening pads help limit noise and vibration. The rear-offset drain is described as a way to preserve under-sink storage space. This sink offers more built-in functionality than the Quikore, but its extra depth may be less comfortable if you prefer not to reach down as far into a basin.
Pros:
- 16-gauge SUS304 stainless steel and 10-inch-deep bowls
- Low divider and sliding workstation track
- 35-inch minimum cabinet size and drain opening are specified
- Sound-deadening pads and drainage channels are included in the design
Cons:
- Workstation accessories are not identified in the supplied package details
- The 10-inch depth may not suit every user or cabinet setup
Verdict: Pick the Lordear if you want a low-divider workstation sink with a deeper basin and have confirmed the accessory package and cabinet fit.
Ruvati 32-Inch Sink: A 16-Gauge 40/60 Bowl Layout
The Ruvati is a 32-inch undermount double bowl made from 16-gauge T-304 stainless steel. Its exterior measures 32-1/8 by 20-5/8 inches. The larger bowl is listed as 9 inches deep and the smaller one as 7 inches deep, creating a noticeable difference in capacity between the two sides.
The package includes a cutout template, mounting brackets, two stainless steel rinse grids, and two basket strainers. The grids help protect the sink bottom while letting water flow underneath. A brushed finish, gently curved corners, sound-proof coating, and rubber padding are also specified. Its 3.5-inch drain openings fit standard garbage disposals, but the listing notes that the included drain is for standard plumbing and that a disposal flange is not included.
Unlike the Lordear and KRAUS options, the supplied details do not describe a low divider or workstation ledge. The Ruvati’s bowl depths may suit shoppers who want a deeper main bowl and a separate, shallower side. Its minimum cabinet size is not specified in the supplied information, so confirm the installation dimensions before ordering.
Pros:
- 16-gauge T-304 stainless steel construction
- Two rinse grids and two basket strainers are listed as included
- Sound-reduction padding and a brushed finish
- Different bowl depths provide separate capacities for kitchen tasks
Cons:
- Disposal flange is not included
- Minimum cabinet size is not stated in the supplied product details
Verdict: The Ruvati is a strong fit if you want a 16-gauge sink with protective grids and strainers, as long as its bowl layout and installation dimensions match your kitchen.
How to Choose a 40/60 Stainless Steel Undermount Sink
Measure the cabinet and countertop opening
Start with the sink’s exterior dimensions and the cabinet space below it. The listed minimum cabinet sizes vary: Quikore and Lordear call for 35 inches, while KRAUS specifies 36 inches. The PHS and Ruvati details provided here do not state a minimum. Also confirm the countertop cutout, mounting clearance, and plumbing space with the sink’s template and installation instructions before you buy.
Check the bowl split and divider height
A 40/60 configuration gives one bowl more room than the other, but the exact bowl dimensions and depth matter more than the label alone. A low divider, as described for the KRAUS and Lordear, may make it easier to handle a wide pan across the center. A full-height divider keeps the bowls more separate. Compare the interior measurements with the cookware and washing tasks you handle most often.
Compare steel gauge and material
The supplied product information lists 16-gauge steel for the PHS, Lordear, and Ruvati, and 18-gauge steel for the Quikore and KRAUS. Gauge is one useful comparison, but also check the stated stainless steel grade and finish. For example, Quikore specifies 304 steel, Lordear specifies SUS304, and Ruvati specifies T-304. Follow the care instructions for the selected finish to help keep it in good condition.
Choose a basin depth that works for you
The sinks here range from bowl depths of 6-1/2 inches on the KRAUS’s smaller side to 10 inches for the Lordear. A deeper basin can hold larger items, but it also means reaching farther down. Check both bowl depths when they differ, and consider your height, the tasks you do at the sink, and the clearance available below the countertop.
Look for useful noise and drainage features
Several options list sound-absorbing pads or coatings intended to reduce noise and condensation. Sloped bottoms, rounded corners, and drainage channels are also described on some models. These features can make daily use and cleanup more convenient, but compare the specific design details rather than assuming every sink handles sound and drainage in the same way.
Confirm drains and included accessories
All five listings describe a 3.5-inch drain opening or standard drain compatibility, but the included parts differ. The KRAUS lists two drain assemblies with strainers; the PHS lists two strainer components; and the Ruvati includes two basket strainers but not a disposal flange. Ruvati also notes that its included drain is for standard plumbing. Check the package list and your existing plumbing before assuming that a disposal flange, grids, or workstation accessories are included.
Plan for undermount installation
An undermount sink sits below the countertop, leaving a smooth edge that lets you wipe crumbs and water into the basin. The installation depends on a compatible countertop, a correctly sized cutout, and secure support beneath the sink. Review the manufacturer’s installation instructions and consider using a qualified installer if you are replacing a sink or modifying a countertop.
Frequently Asked Questions
What does a 40/60 double-bowl sink mean?
It describes a two-bowl layout with one side larger than the other. Exact bowl dimensions and depths vary by model, so check those measurements instead of relying only on the 40/60 label.
Will a standard garbage disposal fit these sinks?
The supplied descriptions list standard 3.5-inch drain openings for these models. However, the drain opening alone does not confirm that every disposal part is included. The Ruvati listing specifically says its disposal flange is not included, so check the package details and your disposal requirements.
Is 16-gauge stainless steel thicker than 18-gauge?
Yes. In the supplied product information, the 16-gauge sinks are described as having thicker steel than the 18-gauge models. Gauge is just one comparison point; also consider the sink’s dimensions, material grade, finish, and installation needs.
What is the benefit of a low divider?
A low divider is shorter than a full-height center wall. It can leave more room for wider cookware to extend across the bowls while preserving a two-basin layout. The KRAUS and Lordear are described as low-divider designs.
Do undermount sinks include everything needed for installation?
Not always. Package contents differ. Some listings include templates, mounting hardware, grids, or strainers, while other components may need to be purchased separately. Check the individual product details and installation instructions before ordering.
How do I know if an undermount sink will fit my cabinet?
Compare the sink’s exterior dimensions and stated minimum cabinet size with your cabinet measurements. Also check the countertop cutout and the clearance needed for bowls, drains, and plumbing. If a listing does not specify a minimum cabinet size, contact the seller or manufacturer for the installation requirements.
Final Recommendation
For a feature-rich design, the Lordear stands out for its 16-gauge steel, 10-inch depth, low divider, and workstation track, provided its accessory package suits your plans. The Quikore is a more straightforward option with a stated 35-inch minimum cabinet size and two 9-inch-deep bowls. If included grids and strainers are priorities, compare the PHS and Ruvati package details closely. Before choosing any model, verify the current listing status, exact fit, and included parts.
