A 26-inch undermount sink can give you a roomy single-bowl workspace without taking up as much counter space as a larger model. The key details to check are the cabinet size, bowl depth, steel grade, drainage layout, and included accessories. These five options share a 26-by-18-inch exterior footprint, but they differ in depth, material, and the extras in the box.

Our Picks: Best 26 Inch Stainless Steel Undermount Kitchen Sink reviews
Couoko: A Well-Equipped Sink with Noise and Condensation Protection
The Couoko combines a T304 stainless steel bowl with a useful set of included accessories: a roll-up drying rack, bottom grid, drain assembly, hardware, and template. Its exterior measures 26 by 18 inches, while the bowl measures 24 by 16 inches and is 8.75 inches deep. That depth may suit you if you want space for everyday dishes but prefer not to reach into a particularly deep basin.
The brand lists a brushed finish, sound-reducing rubber mat, and anti-condensation coating. A gently sloped bottom and X-shaped channels are intended to guide water toward the drain. The standard 3.5-inch drain opening is compatible with a garbage disposal, according to the product details.
This is a strong fit if you value a complete accessory package and want added protection against sink noise and condensation. Compared with the Sarlai and Lordear, its bowl is shallower. That can be a practical trade-off if deep-bowl capacity is not your main priority.
Pros:
- T304 16-gauge stainless steel construction
- Includes a roll-up rack, bottom grid, drain assembly, and template
- Sound-reducing mat and anti-condensation coating
- Sloped base and channels designed to direct water to the drain
Cons:
- Its listed 8.75-inch bowl depth is less than the deeper Sarlai and Lordear options
- Requires a minimum 29-inch base cabinet
Verdict: Choose the Couoko if you want T304 steel, a moderate bowl depth, and a particularly complete set of included accessories.
Sarlai: A Deep T304 Bowl with a Rear-Set Drain
The Sarlai is a 26-by-18-inch undermount sink with a 10-inch exterior depth and a listed interior depth of 9.75 inches. Its T304 16-gauge steel bowl offers ample room for larger cookware, while the rear-set drain keeps the drain area toward the back of the bowl. The drain opening is 3.5 inches and is described as compatible with garbage disposal units.
Its sloped base and X-shaped guide lines are designed to move water toward the drain. Sound-deadening materials are also included to reduce noise and vibration. The package lists a drain assembly, roll-up rack, bottom rinse grid, installation clips, and guidance.
The extra depth makes this one of the roomier choices for washing bulky pots, but it is worth considering your under-sink layout and how comfortable the depth will be for you. The listed minimum cabinet base is 29 inches. Compared with the Couoko, the Sarlai provides a deeper bowl; compared with the Kichae, it has a rear-set rather than center rear drain.
Pros:
- T304 16-gauge stainless steel
- Deep bowl suited to larger cookware
- Rear-set drain and sloped, channeled base
- Includes a roll-up rack, rinse grid, drain assembly, and installation clips
Cons:
- Requires a minimum 29-inch base cabinet
- The 10-inch exterior depth may not suit every user or under-sink arrangement
Verdict: The Sarlai is a good option if a deep T304 bowl and rear-set drain matter more to you than a shallower, easier-to-reach basin.
Kichae: A Balanced 9-Inch Bowl with a Center Rear Drain
The Kichae measures 26 by 18 by 9 inches on the outside, with an interior bowl measuring 24 by 16 by 8.79 inches. It is made from T304 16-gauge stainless steel and has rounded corners, a satin finish, and a center rear drain. Its single bowl leaves an open area for washing larger pans and pots.
The product details list a gently sloped bottom, X-shaped grooves, sound-guard undercoating, and rubber noise-reduction padding. A bottom grid, roll-up drying rack, basket strainer assembly, clips, screws, and cutout template are included. The drain opening is 3.5 inches and can accommodate a garbage disposal unit, according to the listing.
With a middle-of-the-pack bowl depth and T304 steel, the Kichae offers a balanced alternative to the deeper Sarlai and Lordear models. Its center rear drain may be preferable if you want a more central drain position, but check the cabinet plumbing and counter cutout before choosing any sink layout.
Pros:
- T304 16-gauge steel with a satin finish
- Center rear drain and sloped, grooved base
- Includes a bottom grid, roll-up rack, strainer assembly, and cutout template
- Rounded corners designed to make cleaning easier
Cons:
- Interior bowl depth is slightly less than 9 inches
- Requires a minimum 29-inch base cabinet
Verdict: Pick the Kichae if you want T304 steel, a moderate bowl depth, and a center rear drain with several useful accessories included.
Lordear: A Deep Sink with Tight-Radius Corners
The Lordear is listed as a 26-by-18-by-10-inch undermount sink made from T304 16-gauge stainless steel. Its R10 tight-radius corners aim to balance a squared-off look with rounded edges that are easier to wipe than sharp corners. The product information also describes an X-shaped drainage design and a gently sloped bottom.
The package includes a stainless steel dish grid, basket strainer, drying rack, cutout template, and installation instructions. A 29-inch minimum base cabinet is specified. The deeper bowl can be useful for larger cookware, though you should consider how that depth fits your reach and the storage space beneath the sink.
The Lordear shares its 10-inch exterior depth with the Sarlai, but its listing emphasizes R10 corners and a stainless steel dish grid. The product details do not provide an interior bowl measurement, so check the current listing or ask the seller if that dimension is important to your fit.
Pros:
- T304 16-gauge stainless steel
- 10-inch listed exterior depth for washing larger items
- R10 rounded corners and drainage channels
- Includes a dish grid, drying rack, strainer, and cutout template
Cons:
- Interior bowl dimensions are not listed in the supplied product details
- Requires a minimum 29-inch base cabinet
Verdict: Consider the Lordear if you want a deep T304 sink with R10 corners and a useful accessory set, and confirm the interior dimensions before ordering.
Garvee: A 201 Stainless Steel Option with a 9-Inch Bowl
The Garvee is described as a 26-by-18-inch undermount sink with a 9-inch bowl and 16-gauge 201 stainless steel. That steel grade differs from the T304 steel used by the other models here, so compare the material carefully if steel grade is a priority. The listing also specifies a center rear drain, rounded corners, a sloped base, and X-shaped grooves.
Sound-guard undercoating and rubber padding are intended to reduce noise and vibration. The package lists a strainer assembly, screws, clips, and cutout template. Its standard 3.5-inch drain opening is described as fitting most garbage disposals.
The Garvee’s listed bowl depth is similar to the Kichae’s, but the main distinction is its 201 steel rather than T304. The supplied product data marks it unavailable, so treat it as a possible option only if its listing becomes available and its material meets your needs.
Pros:
- 16-gauge construction and a 9-inch listed bowl depth
- Rounded corners and sloped, grooved base
- Includes a strainer assembly and cutout template
- Sound-reducing undercoating and rubber padding
Cons:
- Uses 201 stainless steel rather than T304
- Marked unavailable in the supplied product information
Verdict: The Garvee may suit you if 201 steel fits your priorities, but verify availability and compare its material with the T304 alternatives before deciding.
How to Choose a 26-Inch Stainless Steel Undermount Kitchen Sink
Check Your Cabinet and Counter Cutout
Several of these sinks specify a minimum 29-inch base cabinet, even though the sink itself is 26 inches wide. Confirm the dimensions of your cabinet, countertop opening, and plumbing before you order. A supplied template can help with installation, but do not assume that a replacement sink will fit an existing cutout just because the exterior measurements match.
Compare the Bowl’s Interior Size and Depth
Exterior dimensions do not tell you exactly how much room you have inside the bowl. The Couoko, Sarlai, and Kichae listings provide interior measurements, while the supplied Lordear details do not. Depth ranges from 8.75 inches for the Couoko to 10 inches externally for the Sarlai and Lordear. A deeper bowl can give you more room for bulky cookware, but consider whether its reach and under-sink clearance suit your kitchen.
Understand the Stainless Steel Grade
Four sinks in this group are listed as T304 16-gauge stainless steel; the Garvee is listed as 16-gauge 201 stainless steel. Gauge describes thickness, while the steel grade identifies the alloy. If you are comparing materials, do not treat the same gauge as proof that two sinks use the same steel. Look for clear material details and decide which grade best fits your priorities.
Choose a Drain Position That Works with Your Plumbing
The Sarlai has a rear-set drain, while the Kichae and Garvee specify a center rear drain. Drain position affects how the bowl and plumbing line up, so compare the sink layout with your existing drain and cabinet space. The products listed here have a 3.5-inch drain opening, described as compatible with garbage disposals, but confirm fit with your disposal and drain parts.
Look at Noise Control and Water Flow Features
Stainless steel sinks can transmit the sound of running water and dishes. The product descriptions list sound-reducing mats, undercoating, or rubber padding on these models, though the exact details vary. Sloped bottoms and grooves are also intended to guide water toward the drain. These features may matter if a quieter sink and fewer areas of standing water are priorities for your kitchen.
Compare Included Accessories
A bottom grid can help keep dishes off the sink floor, while a roll-up rack provides a place to dry items over the bowl. Drain assemblies, strainers, clips, and templates can also affect how much you need to source separately. Check the package details for the exact model you are considering, since the included accessories are not identical across all five sinks.
Plan for Undermount Installation
An undermount sink sits below the countertop, creating a surface you can wipe crumbs and spills into the bowl. Installation depends on a suitable counter, a correctly sized cutout, and secure mounting. If you are replacing a sink or changing countertop openings, have the measurements and installation needs checked before purchase; the included template or instructions do not guarantee compatibility with every setup.
Frequently Asked Questions
What size base cabinet do these 26-inch sinks need?
The supplied product details specify a minimum 29-inch base cabinet for the Couoko, Sarlai, Kichae, and Lordear. The Garvee details do not state a minimum cabinet size. Confirm the current listing and measure your cabinet before buying.
Which sink has the deepest bowl?
The Sarlai lists a 10-inch exterior depth and a 9.75-inch interior depth. The Lordear is also listed as 10 inches deep, but its supplied details do not give an interior bowl measurement.
Are these sinks compatible with garbage disposals?
Each supplied product description lists a 3.5-inch drain opening and describes it as compatible with a garbage disposal or most garbage disposals. Check the drain and disposal specifications for your particular setup before installation.
What is the difference between 201 and T304 stainless steel?
They are different stainless steel grades. The Garvee is listed as 201 steel, while the other four models are listed as T304. If material grade matters to you, compare the specifications rather than relying on gauge alone.
Do these sinks come with a drying rack or bottom grid?
The Couoko, Sarlai, Kichae, and Lordear listings include a roll-up rack or drying rack and a bottom grid. The Garvee details list a strainer assembly and installation parts but do not mention a drying rack or bottom grid.
Is an undermount sink harder to install than a drop-in sink?
Undermount installation requires the sink to be secured beneath the countertop and the cutout to fit the sink. The product details include installation parts or guidance for some models, but installation needs depend on your counter and cabinet. Confirm the fit and mounting requirements before starting.
Final Recommendation
For a strong all-around choice, the Kichae combines T304 16-gauge steel, a 9-inch exterior depth, a center rear drain, and a useful accessory set. Choose the Couoko if its shallower bowl and anti-condensation coating appeal to you, or the Sarlai if you want a particularly deep bowl and rear-set drain. Before ordering any model, confirm the cabinet, cutout, drain position, and included accessories for your kitchen.
