Best 50/50 Undermount Sinks for Different Kitchen Setups
A 50/50 undermount sink has two equal-size bowls for separating dishwashing, rinsing, and food preparation. The KRAUS KBU22 is best for a standard 32-inch sink with rounded corners; the KBU32 and Ruvati RVM4350 are better for shoppers who want a low divider for handling larger items. The Ruvati RVM5077 suits a smaller sink opening, while the MILOSEN adds deep bowls and an integrated workstation ledge.

KRAUS KBU22 Standard 32-Inch Sink
The KRAUS KBU22 is best for kitchens with a 36-inch minimum cabinet and space for a conventional 32-inch equal-bowl sink. Its two bowls each measure 14.5 by 16.25 inches, with an 8.25-inch bowl depth. The 18-gauge stainless steel construction and wear-resistant finish make it a practical option for regular kitchen use.
The installation-ready kit includes two drain assemblies with strainers, mounting hardware, and a cutout template. Its rear-set drains and rounded corners are useful details for a streamlined setup and easier cleanup. Choose this model if you want two full-depth bowls rather than a lowered center divider.
Limitation: The listed minimum cabinet size is 36 inches, so it may not suit smaller base cabinets. Confirm the countertop cutout and drain locations before purchase.
KRAUS KBU32 Low-Divider Sink
The KBU32 is best for buyers who want two bowls but need more clearance for large cookware. Its divider sits lower than the rim, making it easier to move some oversized items across the center than with a full-height divider. Both bowls measure 14.5 by 16.875 inches and are 8.625 inches deep.
This 18-gauge stainless steel sink has rounded corners and a wear-resistant finish. The kit includes two strainers, mounting hardware, and a cutout template. Its external dimensions are 32.25 by 18.875 inches, and the stated minimum cabinet size is 36 inches. Choose it over the KBU22 if bowl depth and additional clearance are priorities.
Limitation: The lower divider does not create one completely open basin. Check the larger front-to-back dimension against your cabinet and countertop plan.
Ruvati RVM5077 Compact 28-Inch Sink
The Ruvati RVM5077 is best for a kitchen plan that calls for a narrower double-bowl sink. Its exterior measures 28.5 by 18 inches, making it smaller across than the 32-inch options in this list. It is made from 16-gauge T-304 stainless steel and has a brushed finish with gently curved corners.
Sound-proof coating and rubber padding are listed to help reduce noise and condensation. The package includes two decorative drain covers, two protective bottom grids, cutout templates, and mounting clips. This makes it a useful choice for buyers who want sink-protection accessories included.
Limitation: The provided details do not state the minimum cabinet size or individual bowl dimensions. Verify those measurements and the required cutout before selecting this model.
Ruvati RVM4350 32-Inch Low-Divider Sink
The Ruvati RVM4350 is best for shoppers who want a 32-inch sink with a low center divider. The divider sits three inches below the top of the rim, adding clearance for washing larger pots and pans while retaining separate bowls. Its 16-gauge T-304 stainless steel construction and brushed finish are specified features.
The sink includes sound-proof coating, a protective bottom grid, a cutout template, and mounting clips. Gently curved corners are designed to make cleaning easier. Choose this model if you want the flexibility of a lowered divider and prefer a thicker steel gauge than the 18-gauge KRAUS options listed here.
Limitation: The supplied feature list does not give external dimensions or a minimum cabinet size. Confirm the fit with the product’s current specifications before ordering.
MILOSEN 30-Inch Workstation Sink
The MILOSEN is best for buyers who want deep equal bowls and an integrated workstation ledge. Its exterior dimensions are 30 by 18 by 10 inches, and the stated minimum cabinet size is 33 inches. The product description lists 10-inch-deep basins and a ledge that lets compatible custom accessories slide across the sink.
That design can provide a dedicated surface for preparation and cleanup without using as much counter space. Choose this sink if those workstation features matter more than a simpler basin layout.
Limitation: The listed interior dimensions and basin description are not fully consistent: the stated interior is 28 by 16 by 9 inches, while the feature text describes 10-inch-deep basins. Confirm exact bowl measurements and included accessories before purchase.
Buying Guide: How To Choose A 50/50 Undermount Sink
What cabinet size and sink dimensions should you check?
Start with the sink’s external length, width, and depth, then compare them with the cabinet interior and countertop cutout. Minimum cabinet sizes vary: the KRAUS models specify 36 inches, while the MILOSEN lists 33 inches. Some product listings do not provide this measurement, so confirm it rather than estimating from the sink’s overall width.
Should you choose a full-height or low divider?
A full-height divider keeps the bowls more distinctly separated for tasks such as rinsing and soaking. A low divider preserves two-bowl organization while adding clearance for large cookware. Consider the KRAUS KBU32 or Ruvati RVM4350 if moving larger pots across the center is important.
How do steel gauge and included accessories compare?
A lower gauge number indicates thicker sheet steel. The listed options include 16-gauge Ruvati models and 18-gauge KRAUS models; compare the full specifications and construction details when choosing. Packages also differ: some include strainers and templates, while others list grids, drain covers, or workstation accessories. Check what is included in the current listing.
What should you verify before installation?
Confirm that the sink is intended for undermount installation, and check the cutout template, drain position, faucet arrangement, and countertop requirements with your installer. The product descriptions list different drain placements and accessories. Do not assume a drain assembly or mounting hardware is included unless the listing says so.
Frequently Asked Questions
What does a 50/50 kitchen sink mean?
A 50/50 sink has two bowls of equal size. The separate sides can be used for different kitchen tasks, such as washing and rinsing.
Is a 50/50 sink useful for washing large pots?
It can be, but a full-height divider may limit space for wide cookware. A low-divider model provides more clearance over the divider while keeping two bowls.
What is the advantage of an undermount sink?
An undermount sink attaches below the countertop, creating a continuous surface at the edge. This arrangement lets users wipe crumbs and water from the counter into the sink.
How do I know whether a sink fits my cabinet?
Compare the sink’s exterior dimensions and stated minimum cabinet size with your cabinet measurements. Also verify the countertop cutout and plumbing layout before installation.
Do stainless steel sinks need special cleaning?
Follow the care instructions supplied with the sink. The listed models have finishes and corner designs intended to support routine cleaning, but product details do not establish that every cleaner is suitable.
