ATTOP 33-Inch Double Bowl with Nano Coating
ATTOP’s 33-by-22-inch drop-in sink has two bowls, each 9 inches deep. Its split layout lets you separate tasks, such as rinsing vegetables in one bowl while keeping dishes in the other. A rear drain helps keep the drain area away from the main space where dishes may sit.
The sink has 20-gauge stainless steel bowls and a 3.0 mm edge plate. Its brushed finish and nano coating are designed to make everyday cleanup easier, while the included sound guard undercoating and rubber padding aim to reduce noise and condensation. The package also includes a bottom rinse grid and basket strainer. The 3.5-inch drain opening is listed as compatible with standard garbage disposals.
Compared with the single-bowl choices here, ATTOP offers more separation for kitchen tasks but less uninterrupted space for large cookware. The product information does not specify a minimum cabinet size or stainless steel grade, so measure carefully and confirm fit before ordering.
Pros:
- Two deep bowls make it easy to divide washing and rinsing tasks.
- Rear drain leaves more usable room toward the front of the sink.
- Includes a rinse grid and basket strainer.
- Sound-dampening materials are included.
Cons:
- 20-gauge bowls are thinner than the 18-gauge steel in several competing options.
- Minimum cabinet size and steel grade are not stated in the supplied specifications.
Verdict: Choose ATTOP if you prefer a two-bowl setup with a rear drain and useful included accessories, but verify the cabinet fit before buying.
KRAUS KHT640-33 18-Gauge Single-Bowl Sink
The KRAUS KHT640-33 is a single-bowl drop-in sink measuring 33 by 22 inches overall, with a 9-inch exterior depth. Its bowl measures 30½ by 17 by 8⅝ inches. The single open basin can be more convenient than a divided sink when you need to wash a large pan or several dishes together.
It is made from 18-gauge stainless steel and includes a protective bottom grid, drain assembly with removable strainer, and mounting hardware. The thick mounting deck has a beveled edge, and the sink includes two pre-drilled faucet holes. Sloped sides and channel grooves are intended to help water drain instead of pooling.
KRAUS specifies a 36-inch minimum cabinet size, which is an important check before you buy. The two faucet holes may suit some setups, but they also make it important to compare the sink’s hole layout with your faucet and any other planned accessories. Unlike the textured BELEEB, this model has a wear-resistant finish rather than a micro-pebble surface.
Pros:
- 18-gauge steel and a 9-inch-deep single bowl.
- Includes a bottom grid, drain assembly, strainer, and mounting hardware.
- Sloped base and channel grooves are designed to aid drainage.
- Drop-in design is suited to countertop materials used in retrofit projects.
Cons:
- Requires a minimum 36-inch cabinet.
- Two pre-drilled faucet holes may not match every faucet arrangement.
Verdict: The KRAUS is a practical pick if you want a single, open bowl, 18-gauge steel, and a listed 36-inch cabinet requirement.
Elkay Dayton D233193 Equal Double-Bowl Sink
The Elkay Dayton D233193 is a traditional equal double-bowl sink with overall dimensions of 33 by 19 inches and a listed depth of 6-7/16 inches. Its two bowls can be used separately for washing, soaking, rinsing, or other kitchen jobs. The shallower profile may be worth considering if you do not need the deeper basins offered by the other models in this group.
Elkay describes the sink as made from 300 Series stainless steel and includes sound-deadening pads to help reduce noise and vibration. Its drop-in installation is designed to make the sink a visible countertop feature. The U-channel mounting system places clips inside the channel before installation, which can reduce the need to reach around beneath the sink during that step.
At 19 inches front to back, it is narrower than the 22-inch-wide options here, so it may be a useful size to investigate when your available counter space is limited. Check the actual cutout and countertop dimensions, as well as the 36-inch minimum cabinet requirement. The supplied product data lists this sink as unavailable, so confirm its listing status before planning a purchase.
Pros:
- Equal bowls allow you to handle separate tasks at the same time.
- 19-inch overall width is narrower than the 22-inch models in this comparison.
- Sound-deadening pads are included.
- U-channel clip setup is designed to simplify installation.
Cons:
- Its listed depth is shallower than the 9-inch options.
- Requires a minimum 36-inch cabinet, and the supplied data lists it as unavailable.
Verdict: Consider the Elkay if you want two equal bowls and a narrower footprint, but check availability and make sure its shallower basin suits your needs.
BELEEB 33-Inch Micro-Pebble Single-Bowl Sink
BELEEB’s 33-by-22-inch top-mount sink has a deep, single-bowl design. The listed exterior dimensions are 33 by 22 inches, with a 31-by-18-inch interior and 9-inch depth. That uninterrupted basin is a good layout to consider if you often clean larger cookware and would rather not work around a center divider.
The sink is described as 18-gauge T304 stainless steel and has a 3D micro-pebble finish. The textured surface is designed to diffuse glare and make small marks less noticeable than on a smoother finish. It also has a rubber dampening pad, exterior coating, and rounded interior corners. A bottom drying rack and drain assembly with strainer are included, along with a cutout template.
The textured finish sets this model apart from the brushed or standard finishes on the other single-bowl options. It may appeal if you want a less reflective look, though the surface texture is a different visual and tactile choice from a smooth brushed sink. The supplied information does not state a minimum cabinet size, so confirm the installation dimensions and cutout with the seller before ordering.
Pros:
- Deep, wide single bowl provides open space for larger cookware.
- 18-gauge T304 steel is specified.
- Micro-pebble surface is designed to help disguise small marks and reduce glare.
- Includes a bottom drying rack, drain assembly, strainer, and cutout template.
Cons:
- The textured finish may not suit shoppers who prefer a smooth, uniform surface.
- Minimum cabinet size is not specified in the supplied details.
Verdict: Pick the BELEEB if you want a roomy single bowl and a distinctive textured finish, after confirming that its installation dimensions work for your counter and cabinet.
Quikore 33×22 18-Gauge Single-Bowl Sink
Quikore’s top-mount sink measures 33 by 22 inches overall and has a 29-by-16-inch interior bowl with a listed 9-inch depth. It is a single-bowl design with curved corners, which can leave you with one continuous basin rather than divided compartments.
The sink is specified as 18-gauge 304 stainless steel. Sound-absorbing pads are fitted around the sink and along the bottom, and an exterior coating is intended to limit condensation. The listing also describes a curved bowl shape intended to help water drain and make the corners easier to clean. Its standard 3.5-inch drain opening is listed as compatible with US garbage disposals.
Quikore’s interior dimensions are smaller than the listed interior of the BELEEB, so compare those measurements if you regularly wash oversized pans. The product information lists a 36-inch minimum cabinet size. It does not specify included accessories such as a bottom grid, so check the current product listing if those matter to you.
Pros:
- 18-gauge 304 stainless steel is specified.
- Sound-absorbing pads and an exterior coating are included.
- Single-bowl layout avoids a center divider.
- Standard 3.5-inch drain opening is listed as disposal-compatible.
Cons:
- Requires a minimum 36-inch cabinet.
- Its listed interior is smaller than the BELEEB single bowl’s interior.
Verdict: Quikore is worth considering if you want a 304 stainless steel, single-bowl sink with sound-dampening pads and have the required cabinet space.
How to Choose a 33-Inch Stainless Steel Drop-In Sink
Measure the cabinet and countertop opening
Start with the sink’s exterior dimensions, then compare them with your available counter space and cabinet. A 33-inch sink may need a cabinet wider than 33 inches; for example, the KRAUS, Elkay, and Quikore listings specify a 36-inch minimum cabinet. Do not assume all sinks with the same outside width use the same cutout. Check the manufacturer’s cutout dimensions and template before removing an existing sink or cutting a countertop.
Choose a single or double bowl
A single bowl gives you one open area for larger pans, baking trays, and dish loads. A double bowl separates tasks, which can be useful for rinsing and washing at the same time, but the divider takes up some of the basin’s open space. Think about the cookware you wash most often and whether you prefer a divided work area or one uninterrupted basin.
Compare bowl depth and interior size
Exterior dimensions do not tell the whole story. Compare the interior length and width, as well as bowl depth, to see how much usable space you will have. The models here include deeper 9-inch bowls and a shallower Elkay design. A deep basin may give you more room below the rim, while a shallower sink may be easier to reach across. Match the dimensions to your comfort and daily tasks.
Look at steel gauge and grade
Gauge is one specification to compare, but it is not the only one that matters. Several sinks here list 18-gauge steel, while ATTOP specifies 20-gauge bowls and Elkay identifies 300 Series stainless steel. BELEEB lists T304 steel and Quikore lists 304 steel. Check the product details for the exact material and gauge, and consider how the finish and sink construction fit your priorities.
Consider finish, sound control, and included accessories
Finishes range from brushed and nano-coated surfaces to BELEEB’s micro-pebble texture. Choose the appearance and surface you prefer, keeping in mind that different finishes can show marks and water spots differently. Sound pads or undercoating are included on several models, and some also come with a bottom grid, drain parts, strainer, or drying rack. Compare what is in the box so you know what you may need to purchase separately.
Check faucet holes and drain placement
Confirm the number and location of faucet holes before choosing a sink. The KRAUS listing specifies two pre-drilled faucet holes; the other supplied descriptions vary in how much hole information they provide. Also check drain placement and drain opening size, especially if you plan to reuse a disposal or existing plumbing. A compatible opening does not by itself confirm that every part of your current setup will fit.
Plan for drop-in installation
A drop-in sink rests on the countertop rim, which can make it a useful option for replacement projects and a range of countertop materials. Still, the opening, clips, faucet holes, and plumbing need to match the sink. Read the installation instructions and use the listed template where provided. If you are unsure about cutting the counter or connecting the drain, arrange help from a qualified installer.
FAQs
Will every 33-inch sink fit a 36-inch cabinet?
No. Check the minimum cabinet size for the exact model. KRAUS, Elkay, and Quikore list a 36-inch minimum, while the supplied details for ATTOP and BELEEB do not state one. Confirm the sink’s measurements and installation requirements before buying.
Is a single-bowl or double-bowl sink better?
Neither layout is best for everyone. A single bowl gives you an open space for large cookware, while double bowls let you separate tasks. Choose based on the items you wash and how you like to use your sink.
What does 18-gauge stainless steel mean for these sinks?
It is a specification describing the thickness category of the steel. Several sinks in this comparison list 18-gauge construction, while ATTOP specifies 20-gauge bowls. Compare the stated gauge alongside the steel grade, bowl design, and other construction details rather than relying on one specification alone.
Do drop-in sinks work with different countertop materials?
Drop-in sinks are designed to sit on top of the counter, and the KRAUS listing describes its model as suitable for retrofitting with any countertop material. Always confirm the installation instructions for your specific sink and counter, including the required cutout and mounting method.
Can I connect a garbage disposal to these sinks?
ATTOP and Quikore list a 3.5-inch drain opening and state compatibility with standard US garbage disposals. For any model, check the drain assembly and disposal requirements against your existing plumbing before installation.
Which sink is the shallowest option here?
The Elkay Dayton is listed at 6-7/16 inches deep. The other models in this comparison are listed with 9-inch exterior depths or bowl depths, though the exact measurement type can differ by product. Compare the manufacturer’s dimensional drawing before deciding.
Final Recommendation
For a roomy single-bowl sink with stated 18-gauge steel and clear cabinet requirements, the KRAUS KHT640-33 is a straightforward option to compare. Choose ATTOP or Elkay if you prefer two bowls, and consider BELEEB or Quikore if you want a single basin with a different finish or feature set. Before ordering any 33-inch drop-in sink, confirm the cutout, cabinet clearance, faucet-hole layout, and included drain parts against your kitchen.
