A 27-inch drop-in stainless steel sink can give you a roomy single bowl without taking up as much counter space as a larger kitchen sink. The key is matching the sink’s full outside dimensions and required cabinet size to your space—not relying on the “27-inch” label alone. These five options range from compact 27-by-18-inch models to deeper, wider workstation sinks, with different steel gauges and included accessories.
Our comparison focuses on the listed dimensions, construction, installation style, and package contents. Check the product details and your countertop cutout before ordering, since fit can depend on more than the sink’s length.

Our Picks: Best 27 Inch Stainless Steel Drop In Kitchen Sink reviews
1. Koardink 27×18-Inch Sink Combo: Compact Size with Useful Extras
The Koardink is a single-bowl top-mount sink with a smaller footprint than the 27-by-22-inch options in this list. Its exterior measures 27 by 18 inches, while the bowl measures 25 by 14 by 9 inches. That gives you room for everyday dishes and cookware while keeping the front-to-back measurement more modest.
The listing describes the sink as 11-gauge stainless steel and includes a bottom grid, silicone mat, and drain assembly. It also specifies a brushed finish, sound-dampening pads, an anti-condensation coating, and an X-shaped bottom channel intended to guide water toward the drain. Those details make it a well-equipped package, though you should confirm that its outside dimensions and cutout requirements match your counter.
Compared with the deeper Oxwiser and Hovheir models, the Koardink has a smaller bowl footprint. That can be a benefit in a compact kitchen, but it gives you less room for oversized pans. The included mat and grid may also be useful if you want basic sink protection and accessories in one package.
Pros:
- Compact 27-by-18-inch exterior size
- Listing specifies 11-gauge stainless steel
- Includes a bottom grid, silicone mat, and drain assembly
- Sound-dampening pads and anti-condensation coating are specified
Cons:
- Its bowl is smaller than the 27-by-22-inch options
- Confirm the countertop cutout and installation details before purchase
Verdict: Choose the Koardink if you want a compact 27-inch top-mount sink with several included accessories and do not need the broadest possible bowl.
2. Oxwiser 27-Inch Workstation Sink: Deep Bowl and Included Accessories
The Oxwiser is a 27-by-22-inch top-mount single-bowl sink with a 10-inch depth. Its interior measures 24½ by 17 by 10 inches, giving you more bowl width and depth than the 27-by-18-inch models. The manufacturer lists a minimum cabinet size of 30 inches, so check your cabinet opening before considering it.
It is made from 16-gauge T304 stainless steel with a brushed finish. The package includes a dish grid, three-piece basket strainer waste, collapsible colander basket, and kitchen towel. Its standard 3.5-inch drain opening is listed as compatible with garbage disposal units. Soundproofing pads and an anti-condensation undercoating are also specified.
The extra bowl space is useful when washing larger pots or stacking dishes, while the included colander adds a practical workstation element. Its 22-inch front-to-back size is not a fit for every counter, however. The product description also has confusing wording about installation, so confirm the exact top-mount setup and cutout measurements with the seller or installation instructions before you buy.
Pros:
- Deep 10-inch bowl with a 24½-by-17-inch interior
- 16-gauge T304 stainless steel construction
- Includes a grid, strainer, collapsible colander, and towel
- Minimum 30-inch cabinet size is stated in the listing
Cons:
- The 22-inch front-to-back size may not fit a compact counter
- Installation wording in the listing is unclear, so verify the details
Verdict: The Oxwiser is a strong option if you have the required cabinet space and want a deep bowl with a useful set of included workstation accessories.
3. Hovheir 27×22-Inch Sink: Deep Top-Mount Bowl for Larger Cookware
The Hovheir is another large-bowl choice, with a 27-by-22-inch exterior and a 10-inch depth. The product information says it is made from 16-gauge T304 stainless steel with a satin finish. Its package includes a drain assembly and bottom rinse grid.
The bowl’s size can make it easier to handle tall pots and stacks of dishes than a shallower or narrower sink. An X-shaped channel is designed to direct water toward the drain, while the listing describes rounded R10 corners to make the bowl easier to wipe. Rubber pads and an underside coating are intended to reduce noise and condensation.
Its dimensions put it in the same roomy category as the Oxwiser, but the listed package is simpler: it includes a grid and drain assembly rather than a colander and other workstation accessories. The 22-inch front-to-back measurement is the main fit concern. Check your cabinet, counter depth, and cutout measurements before choosing it.
Pros:
- 10-inch-deep bowl suited to larger cookware
- 16-gauge T304 stainless steel construction
- Includes a drain assembly and bottom rinse grid
- Rounded corners, drainage channels, and sound-dampening pads are specified
Cons:
- The 22-inch front-to-back dimension needs careful fit checking
- Does not list the extra workstation accessories included with the Oxwiser
Verdict: Consider the Hovheir if a deep, wide single bowl matters more to you than having a larger set of included accessories.
4. MILOSEN 27×16-Inch RV Sink: Shallower Profile for Compact Kitchens
The MILOSEN is designed for RV and camper kitchens, where a deeper, wider sink may not suit the available space. Its exterior measures 27 by 16 inches, and its bowl is 6 11/16 inches deep. The interior is listed as 25 by 14 inches. This gives it a different role from the 10-inch-deep home kitchen options in this roundup.
The sink uses 16-gauge T304 stainless steel and can be installed as either a drop-in or undermount, according to the product details. It includes a sink strainer and protective bottom grid. X-shaped grooves support drainage, while rubber pads and sound-guard undercoating are intended to reduce noise and vibration.
The shallower bowl may be more practical in a camper or other compact kitchen, but it will hold less water and offer less vertical room for tall cookware than the Oxwiser or Hovheir. Its 27-by-16-inch size is also noticeably narrower front to back than the other standard kitchen sinks here. Confirm that the installation style and dimensions work with your counter before ordering.
Pros:
- Compact 27-by-16-inch exterior with a relatively shallow bowl
- 16-gauge T304 stainless steel construction
- Listed for drop-in or undermount installation
- Includes a strainer and protective bottom grid
Cons:
- Shallower bowl offers less room for tall pots than 10-inch-deep options
- Its RV-focused size may not suit a standard kitchen replacement
Verdict: Pick the MILOSEN for an RV, camper, or compact kitchen where a smaller front-to-back footprint and flexible installation matter most.
5. TSIBOMU 27×18-Inch Sink: Simple Single Bowl with a Bottom Grid
The TSIBOMU is a 27-by-18-inch drop-in sink with a 25-by-14-inch interior and a 9-inch bowl depth. Its size is similar to the Koardink, making it a more compact choice than the 27-by-22-inch models. The listing specifies 18-gauge T304 stainless steel and describes the sink as handmade.
A bottom grid is included, and the standard 3.5-inch drain opening is listed as compatible with garbage disposal units. The sink has an X-shaped drainage channel and rounded R10 corners. Rubber dampening pads and a stone-guard undercoating are also specified to help limit noise and condensation.
This is a simpler package than the Koardink combo: the TSIBOMU listing mentions a bottom grid but does not list a silicone mat or drain assembly. Its 18-gauge steel is a lighter gauge than the 16-gauge Oxwiser, Hovheir, and MILOSEN; the gauge number alone does not determine overall quality, but it is a useful construction difference to compare. Confirm exactly which drain parts are included before planning installation.
Pros:
- Compact 27-by-18-inch exterior and 9-inch bowl depth
- T304 stainless steel with a bottom grid included
- Standard 3.5-inch drain opening is listed for disposal compatibility
- Rounded corners and drainage channels are designed for easier cleanup
Cons:
- 18-gauge steel is lighter gauge than the 16-gauge options here
- The listing does not specify a drain assembly as included
Verdict: The TSIBOMU is a practical option if its 27-by-18-inch footprint fits your counter and you want a single bowl with a bottom grid.
How to Choose a 27-Inch Stainless Steel Drop-In Kitchen Sink
Measure the Countertop Cutout and Cabinet
Start with the existing sink opening, not just the sink’s advertised width. A 27-inch label usually refers to the sink’s outside length, while the opening needed for installation can differ. Check the full product dimensions, cutout template, rim size, and installation instructions. Also measure the cabinet below; the Oxwiser, for example, lists a 30-inch minimum cabinet size.
Compare the Bowl’s Width, Depth, and Shape
Exterior dimensions do not tell the whole story. Look at the interior bowl measurements and depth to see whether the sink will handle your usual dishes and cookware. The 27-by-22-inch Oxwiser and Hovheir have 10-inch-deep bowls, while the 27-by-18-inch Koardink and TSIBOMU have 9-inch depths. The MILOSEN is shallower, at 6 11/16 inches, which may be useful in a compact RV kitchen but gives you less vertical room.
Understand Stainless Steel Gauge and Grade
Gauge is a measure of steel thickness, and a lower gauge number generally indicates thicker steel. The products here list gauges from 11 to 18, with several specifying T304 stainless steel. Compare both the stated gauge and steel grade, but also consider the sink’s construction, finish, and the amount of sound-dampening material. A gauge alone does not describe every aspect of a sink’s durability.
Check the Installation Style
Drop-in, or top-mount, sinks sit in a countertop opening with the rim resting on top. That makes them a common choice for replacing an existing top-mount sink, but the cutout and rim still need to match. The MILOSEN is listed for drop-in or undermount installation, while the other products are presented as top-mount or drop-in sinks. For any unclear listing, verify the exact installation method and included mounting parts before purchase.
Review the Drain and Disposal Details
Check the drain opening size and whether the package includes a drain assembly, basket strainer, or disposal-compatible connection. The Oxwiser and TSIBOMU list 3.5-inch drain openings, and the Koardink includes a drain assembly. The Hovheir also lists a drain assembly. The TSIBOMU product information does not specify that one is included, so check what you may need to buy separately.
Consider Accessories and Everyday Cleanup
A bottom grid can help keep cookware off the sink floor, while a colander or silicone mat adds different kinds of convenience. The Oxwiser includes a collapsible colander, and the Koardink includes a silicone mat. Drainage grooves are designed to guide water toward the drain, while rounded corners can make it easier to wipe the bowl. These features can be helpful, but they do not replace checking the sink’s size and installation fit.
Look for Noise and Condensation Protection
Running water and dishes can create noise in a stainless steel bowl. Several listings describe rubber or sound-dampening pads, and some also specify an underside coating intended to reduce condensation. These features may help limit noise or moisture beneath the sink, but the exact materials and coverage can vary by model. Check the product details if sound control is important in your kitchen.
Frequently Asked Questions
Will any 27-inch sink fit a 27-inch opening?
Not necessarily. The 27-inch measurement generally describes the sink’s outside length, not the countertop cutout. Compare the cutout dimensions, rim, cabinet size, and installation instructions before ordering.
Is a 27×22-inch sink bigger than a 27×18-inch sink?
It is wider from front to back, while both have a listed 27-inch length. The 27×22-inch options in this guide also have 10-inch-deep bowls, but the larger exterior size may require more counter and cabinet space.
Which sink is best for washing large pots?
The Oxwiser and Hovheir both list 27×22-inch exterior dimensions and 10-inch bowl depths. Their larger bowls may suit bulky cookware better than the narrower 27×18-inch options, provided your cabinet and counter can accommodate them.
What does stainless steel gauge mean?
Gauge describes steel thickness; a lower gauge number generally means thicker steel. The listed models range from 11-gauge to 18-gauge. Compare the gauge alongside the stated steel grade, dimensions, finish, and other construction details.
Can I use a stainless steel sink with a garbage disposal?
Some of these listings specify disposal-compatible drain details. The Oxwiser and TSIBOMU list standard 3.5-inch openings, and the Koardink includes a drain assembly. Check the product specifications and your disposal requirements to confirm the connection will work.
Does a bottom grid come with every sink here?
No. The listed packages for all five products mention a grid, though the wording differs: some call it a bottom grid, dish grid, rinse grid, or protective grid. Confirm the final package contents on the product page before ordering.
Which option is best for an RV or camper?
The MILOSEN is specifically described as an RV sink. Its 27×16-inch exterior and shallower bowl are intended for limited-space kitchens, and the listing allows drop-in or undermount installation. Confirm the measurements and installation requirements for your RV counter.
Final Recommendation
For a roomy household kitchen, the Oxwiser stands out for its 10-inch-deep bowl and included workstation accessories, provided you have the listed minimum cabinet space and verify its installation details. The Hovheir is another deep-bowl choice with a simpler included package. If your counter is more compact, compare the Koardink and TSIBOMU by their package contents and listed steel gauge. For an RV or camper, the MILOSEN is the most purpose-built option. In every case, measure your cutout and cabinet before making a decision.
