A double-bowl undermount sink gives you separate spaces for washing and rinsing, or for handling dishes and food prep at the same time. The right choice depends on more than the bowl layout: check the sink’s outside dimensions against your cabinet, compare the steel gauge and bowl depth, and decide whether a low divider would make large cookware easier to wash. These five options include standard 50/50 designs, a 70/30 split, and low-divider models.

Our Picks: Best Double Bowl Stainless Steel Kitchen Sink Undermount reviews
1. KRAUS Premier: A Low Divider for More Room to Work
The KRAUS Premier combines two equal bowls with a low center divider. Its outside dimensions are 32¼ by 18⅞ inches, and the minimum cabinet size is 36 inches. Each bowl measures 14½ by 16⅞ inches, with a listed depth of 8⅝ inches. Check those measurements against your cabinet and countertop cutout before ordering.
The sink is made from 18-gauge stainless steel and has rounded corners intended to make cleanup easier. A sloped bottom helps water drain, while large silencer pads and full insulation are designed to reduce noise and vibration. The low divider leaves more clearance when you need to wash a large item across both bowls, though it won’t keep water contained as fully as a standard-height divider.
The package includes two drain assemblies with strainers, mounting hardware, and a cutout template. That’s a useful set of installation basics, but you’ll still need to confirm that your plumbing and any garbage disposal will fit. The disposal model listed as recommended is sold separately.
Pros:
- Low divider creates extra room for wide cookware.
- 18-gauge steel and insulation are practical features for everyday use.
- Rounded corners and a sloped bottom support easier cleaning and drainage.
- Two drain assemblies and mounting hardware are included.
Cons:
- Requires a cabinet at least 36 inches wide.
- The low divider may allow more splash between bowls than a full-height divider.
Verdict: Choose the KRAUS if you want equal-size bowls and the flexibility of a low divider, and your cabinet meets the 36-inch minimum.
2. Rhbamoa 32-Inch Sink: Heavy-Gauge Steel for a Standard 50/50 Layout
This 32-by-18-by-9-inch Rhbamoa sink has two equal bowls and is described as being made from 16-gauge T304 stainless steel. Its brushed finish is intended to help disguise fingerprints, water spots, and small scratches. Sound-absorbing pads on the sides and bottom, along with an exterior coating to limit condensation, add practical details beneath the sink.
The listing describes undermount installation and also says the sink supports top-mount installation. However, the included cutout template is for undermount use only, and the product description advises consulting a professional for top-mount dimensions and sealing. If you’re considering that alternate installation, confirm the requirements before buying rather than assuming the template covers it.
The sink includes strainers and has standard 3.5-inch drain openings described as compatible with US garbage disposals. The supplied product data currently marks this item as unavailable, so check its listing for current availability and details before making a decision.
Pros:
- 16-gauge T304 steel is the thickest steel listed among these picks.
- Equal bowls provide a familiar setup for separating tasks.
- Sound pads and an anti-condensation coating are included in the design.
- Standard 3.5-inch drain openings are specified.
Cons:
- The supplied product data marks it as unavailable; check the listing before planning a purchase.
- Top-mount installation requires separate attention to cutout dimensions and sealing.
Verdict: This is worth considering if you want a 16-gauge 50/50 sink, but verify availability and installation details first.
3. Highpoint Collection: A 70/30 Split for Different-Sized Tasks
Unlike the equal-bowl models in this group, the Highpoint Collection sink uses a 70/30 split. That layout gives you one larger bowl and one smaller one, which can suit a routine that uses the main basin for pots or dishes and the smaller basin for rinsing or food prep. The product details don’t provide overall or bowl dimensions, so check the listing and confirm the measurements before you plan a countertop cutout.
The sink is described as 18-gauge 304 stainless steel with a brushed finish. Full rubber padding and undercoating are intended to reduce noise. Rounded corners and included basket strainers add to its practical design, while the package also lists mounting hardware, a template, and drains.
The tradeoff is that a 70/30 arrangement gives you less flexibility for tasks that need two similarly sized bowls. There are also fewer supplied sizing details here than for several of the other options, making a fit check especially important.
Pros:
- 70/30 layout provides one larger bowl for bigger items.
- 18-gauge 304 steel is specified.
- Rubber padding and undercoating are designed to help quiet use.
- Template, mounting hardware, drains, and basket strainers are included.
Cons:
- Overall and bowl dimensions aren’t provided in the supplied product details.
- The smaller bowl may be limiting if you prefer two equal work areas.
Verdict: Pick the Highpoint if a larger main bowl is more useful to you than two equal basins, but confirm the exact fit before ordering.
4. Lanxlic 32-Inch Sink: 50/50 Design with a 35-Inch Cabinet Minimum
The Lanxlic is a 50/50 sink made from 18-gauge 304 stainless steel. Its listed outside dimensions are 32 5/16 by 18½ by 9 inches, with a stated minimum cabinet size of 35 inches. The product details give internal dimensions of 14⅝ by 16½ by 9 inches for a bowl. Confirm the full cutout and bowl specifications on the listing before installation.
Sound-absorbing rubber pads cover the sides and bottom, and an anti-condensation coating is intended to help protect the cabinet from moisture. The sloped bottom is designed to encourage drainage, while the rounded corners and brushed finish are presented as easy-care features. Its standard 3.5-inch drain opening is described as fitting most US garbage disposals.
There is a wording mismatch in the supplied description: the title and installation details identify it as an undermount sink, while another line calls it a drop-in sink. Because installation style affects the countertop opening and support, verify the specific configuration and template with the seller before you commit.
Pros:
- Equal-size bowls suit shoppers who want two similar work areas.
- 18-gauge 304 steel, sound pads, and anti-condensation coating are specified.
- 35-inch minimum cabinet size is stated.
- Sloped bottom and rounded corners are designed to make cleaning and drainage easier.
Cons:
- The product description conflicts on whether the sink is drop-in or undermount.
- Verify the supplied dimensions and installation template before ordering.
Verdict: The Lanxlic has useful 50/50 dimensions and under-sink protection features, but resolve the installation-style inconsistency before buying.
5. Ruvati RVM4350: Low Divider with Protective Bottom Grids
The Ruvati RVM4350 pairs a 50/50 layout with a low center divider set three inches below the rim. That extra clearance can help when you’re washing a wide pot or pan across the center. The sink measures 32¼ by 18⅞ inches on the outside, with two bowls listed at 14½ by 16⅞ inches and an 8½-inch bowl depth.
It is made from 16-gauge T-304 stainless steel and has a commercial-style brushed finish. A sound-proof coating and heavy rubber padding are intended to reduce noise and condensation. The package includes two stainless steel bottom grids, two basket strainers, mounting brackets, and a cutout template.
The 3.5-inch drain opening is described as compatible with a standard garbage disposal, but the included drain is for standard plumbing. The disposal flange is not included, so plan to use the flange supplied with your disposal. As with the KRAUS, the low divider improves access across the bowls but may not contain splashes as well as a full-height divider.
Pros:
- Low divider makes it easier to handle wide cookware.
- 16-gauge T-304 steel is specified.
- Two protective bottom grids and two basket strainers are included.
- Sound-proof coating and rubber padding are designed to reduce noise.
Cons:
- The disposal flange is not included.
- A low divider may provide less separation between bowls during messy tasks.
Verdict: Choose the Ruvati if you want a low-divider 50/50 sink with included bottom grids and a 16-gauge build, and you’re prepared to supply the correct disposal flange.
How to Choose a Double-Bowl Stainless Steel Undermount Sink
Measure Your Cabinet and Countertop Opening
Start with the cabinet’s inside width, then compare it with the sink’s stated minimum cabinet size. These numbers are not interchangeable with the sink’s outside width. Also check the countertop opening, countertop thickness, and space needed for clips and plumbing. The KRAUS lists a 36-inch minimum cabinet, while the Lanxlic lists 35 inches; don’t assume a sink will fit just because its outside width seems right.
Choose a Bowl Split That Matches Your Routine
A 50/50 sink gives you two similarly sized basins, which can help when you want to divide washing and rinsing evenly. A 70/30 layout gives you one larger bowl and one smaller one, which may suit cooks who regularly handle bigger pots in the main basin. Consider the items you wash most often, not just the number of bowls.
Decide Whether a Low Divider Is Useful
A low divider leaves more open space across the center, making it easier to wash wide cookware without lifting it over a full-height partition. It also means the bowls are less separated near the top, so water and suds may move between them more readily. Choose a standard-height divider if keeping the two sides more distinct matters more than extra clearance.
Compare Steel Gauge and Finish
The product details list 16-gauge steel for the Rhbamoa and Ruvati, and 18-gauge steel for the KRAUS, Highpoint, and Lanxlic. Gauge is one factor to compare, but also check the listed steel grade, construction, and finish. A brushed finish is described on several models and may help disguise everyday marks, but no finish makes a sink immune to scratches or water spots.
Look for Noise and Condensation Controls
Stainless steel sinks can transmit the sound of running water and dishes. Several picks list sound-absorbing pads or coatings, and the Rhbamoa and Lanxlic also specify anti-condensation coatings. These features are worth checking if a quieter sink or moisture protection beneath the basin is a priority. They don’t replace good installation or keeping the cabinet dry.
Check Bowl Depth, Drain Fit, and Included Parts
A deeper bowl may hold more dishes, but make sure it leaves enough room for the drain, disposal, and plumbing underneath. Compare the listed drain opening with your disposal setup, and check whether a disposal flange is included or must come from your existing unit. Also note which models include strainers, bottom grids, mounting clips, or a cutout template.
Confirm the Installation Type and Template
Undermount sinks attach beneath the countertop, so the cutout and support method must match the sink and counter material. Read the product details carefully when they describe more than one installation method. In particular, the Lanxlic details include conflicting wording about drop-in versus undermount installation, while the Rhbamoa listing says its supplied template is for undermount use only. Ask the seller or installer to confirm the correct template and installation method before work begins.
Frequently Asked Questions
What does a 50/50 double-bowl sink mean?
It means the two bowls are designed to be similar in size. This layout can make it easier to split tasks evenly, such as washing in one side and rinsing in the other.
Is a low-divider sink better for large pots?
A low divider gives you more clearance across the center, which can make wide cookware easier to handle. The tradeoff is less separation between the bowls near the top, so consider how much you value splash control.
What cabinet size do I need for a 32-inch sink?
It depends on the specific model, not just the sink’s outside width. The KRAUS lists a 36-inch minimum cabinet and the Lanxlic lists 35 inches. Check the required cabinet size, countertop cutout, and installation instructions for the exact sink you choose.
Do these sinks include a garbage disposal?
The supplied product information does not list a garbage disposal as included. Check the package details and your plumbing setup. The Ruvati description specifically says its disposal flange is not included.
Which sink has the thickest steel in this comparison?
The Rhbamoa and Ruvati are listed as 16-gauge models. The KRAUS, Highpoint, and Lanxlic are listed as 18 gauge. Compare the steel grade and other construction details as well as gauge.
Are all five sinks confirmed to be undermount models?
The product titles or descriptions identify them as undermount sinks, but the Lanxlic details also use drop-in wording, and the Rhbamoa describes an additional top-mount option. Verify the intended installation type and correct template with the seller before installation.
Final Recommendation
For a low-divider design with clear dimensions and included drain assemblies, the KRAUS Premier is a practical all-around choice if your cabinet is at least 36 inches wide. The Ruvati is a strong alternative if you want 16-gauge steel and included bottom grids. If you prefer two differently sized bowls, consider the Highpoint, but confirm its dimensions first. Before choosing any model, match the sink to your cabinet, countertop opening, and plumbing, and verify installation details where the product listing is unclear.
