A one-bowl sink bundled with a garbage disposal can simplify a kitchen upgrade by pairing a roomy washing area with a disposal matched to the sink’s drain. These three KRAUS workstation options all include a 3/4 HP continuous-feed disposal, but they differ in material, mounting style, size, and included accessories. Before choosing, check your cabinet dimensions, countertop setup, and the space available beneath the sink.

Our Picks: Best One Bowl Sink With Garbage Disposal reviews
1. KRAUS Bellucci 32-Inch Undermount Granite Composite Workstation Sink
The Bellucci pairs a 32-inch undermount sink with a 3/4 HP KRAUS WasteGuard disposal. Its single bowl measures 30 by 16 inches and is 9 3/8 inches deep. The sink is made from a blend of 80% natural quartz and acrylic resin, giving it a metallic black, stone-like look.
An integrated ledge supports the included heavy-duty cutting board and roll-up dish-drying rack, so you can use the sink area for prep and drying. The undermount design creates a smooth transition from countertop to basin, which can make it easier to sweep crumbs and spills into the sink. The package also includes a drain assembly with strainer, stopper/plunger, disposal connectors, and power cord.
The included disposal has a 40.6-ounce grinding chamber and a stated 3/4 HP, 3800 RPM motor. It is continuous-feed, so it can grind food waste while running rather than requiring you to load scraps in batches. The minimum cabinet size is 36 inches, and the disposal needs at least 10 1/4 inches of installation clearance.
This is the most distinctive choice of the three if you want a dark composite finish and a broad prep surface. Its 19-inch overall width and undermount installation call for careful cabinet and countertop checks. The supplied product details do not specify a warranty term for this model, so confirm warranty coverage and package details before ordering.
Pros:
- Granite composite made with 80% natural quartz and acrylic resin
- Workstation ledge and included cutting board and drying rack
- Includes a 3/4 HP continuous-feed disposal
- Undermount style allows a clean countertop-to-sink transition
Cons:
- Requires a minimum 36-inch cabinet and a compatible undermount countertop setup
- Dark composite finish may not suit every kitchen design
Verdict: Choose the Bellucci if you want a dark, stone-look workstation sink with a disposal included and your kitchen can accommodate its undermount dimensions.
2. KRAUS Kore 32-Inch Undermount Stainless Steel Workstation Sink
The 32-inch Kore is an undermount single-bowl sink made from 16-gauge stainless steel. Its deep basin, tight-radius corners, and offset drain are designed to provide an open work area for washing large cookware. It needs a minimum 36-inch cabinet.
The integrated workstation ledge lets you use the included solid bamboo cutting board and roll-up drying rack over the basin. The package also lists a protective bottom grid, basket strainer drain assembly, decorative drain cap, and sink stopper/plunger. Because it mounts beneath the counter, it is best suited to a countertop and cabinet setup designed for an undermount sink.
Like the other options here, this model includes a 3/4 HP continuous-feed disposal with a 40.6-ounce grinding chamber and a stated speed of 3800 RPM. Its listed disposal dimensions are 7 1/2 inches wide by 15 1/4 inches high, with a minimum installation clearance of 10 1/4 inches. A wall switch or separately sold air switch activates the disposal. The product information lists a limited lifetime warranty; check the seller’s listing for the exact coverage terms.
Compared with the Bellucci, the Kore offers stainless steel rather than a dark composite finish. It is also a better fit if you prefer the look of steel and want the listed bottom grid and bamboo board. Its 32-inch size still requires more cabinet room than the 30-inch drop-in option below.
Pros:
- 16-gauge stainless steel construction
- Workstation ledge with bamboo cutting board and roll-up drying rack
- Includes a protective bottom grid and 3/4 HP disposal
- Deep single bowl with an offset drain for an open washing area
Cons:
- Requires a minimum 36-inch cabinet
- Undermount installation may not suit every existing countertop
Verdict: Pick the 32-inch Kore if you want a stainless undermount workstation sink with a generous bowl and a disposal included.
3. KRAUS Kore 30-Inch Drop-In Stainless Steel Workstation Sink
This 30-inch Kore is the drop-in option in the group. It measures 30 inches long, 22 inches wide, and 9 1/2 inches deep, and it requires a minimum 33-inch cabinet. Its top-mount design can be installed with different types of kitchen counter material, according to the product details.
The 16-gauge stainless steel sink has a single deep bowl, tight-radius corners, and an offset drain. Its integrated ledge works with the included bamboo cutting board and roll-up drying rack. The package also lists a protective bottom grid, basket strainer drain assembly, decorative drain cap, and stopper/plunger.
The included disposal has the same listed core specifications as the other two models: 3/4 HP, 3800 RPM, continuous-feed operation, and a 40.6-ounce grinding chamber. It needs a minimum 10 1/4 inches of installation clearance. The listing states a limited lifetime warranty; confirm which parts and components are covered before you buy.
This model is the practical choice when you want a workstation sink and disposal but have less cabinet space or prefer a top-mount installation. Its 30-inch length is smaller than the two undermount options, though its 22-inch overall width still needs to fit your counter layout. Measure the cutout and check the sink’s full dimensions rather than relying on the nominal 30-inch size alone.
Pros:
- Requires a smaller minimum cabinet size than the 32-inch models
- Drop-in design works with different countertop materials
- Includes workstation accessories and a 3/4 HP disposal
- 16-gauge stainless steel bowl with an offset drain
Cons:
- Drop-in rim is visible on the countertop
- Overall width is 22 inches, so check counter space and cutout dimensions
Verdict: Choose the 30-inch Kore if you want stainless steel, a drop-in installation, and a lower minimum cabinet-size requirement than the 32-inch models.
How to Choose a One-Bowl Sink With Garbage Disposal
Measure the cabinet and sink space
Start with the minimum cabinet size, then compare it with the sink’s full outer dimensions. The 32-inch Bellucci and Kore require a minimum 36-inch cabinet, while the 30-inch drop-in Kore lists a 33-inch minimum. Also measure the counter cutout and the space beneath the sink so the bowl, plumbing, and disposal can fit without crowding.
Check disposal clearance and connections
Each included disposal is listed as 7 1/2 inches wide and 15 1/4 inches high, with at least 10 1/4 inches of installation clearance. Make sure your cabinet has room for the disposal and connected plumbing. The products are described as compatible with a standard round 3 1/2-inch drain opening and standard 1 1/2-inch kitchen plumbing connections. Confirm your setup before ordering.
Choose the right mounting style
An undermount sink sits below the countertop and gives you a smooth surface to wipe crumbs and water into the bowl. It requires a compatible countertop installation. A drop-in sink rests on the counter, with its rim visible, and the 30-inch Kore listing says it can be installed with different countertop materials. Choose based on your existing counter and the look you want.
Compare materials and finishes
The Bellucci is made from granite composite using 80% natural quartz and acrylic resin, and it has a metallic black finish. Both Kore models use 16-gauge stainless steel. Think about which look fits your kitchen and how much the sink’s color and material matter to your design. The supplied details do not provide care instructions for either material, so check the manufacturer’s guidance for cleaning and maintenance.
Consider how you will use the workstation accessories
All three sinks have an integrated ledge for working over the bowl. Their included accessories vary: the Bellucci lists a heavy-duty cutting board and roll-up rack, while the Kore models add a protective bottom grid and solid bamboo cutting board. These pieces can help keep prep and drying tasks over the sink, but check the package contents on the product listing before buying.
Understand the disposal controls and operation
Each bundle includes a 3/4 HP continuous-feed disposal. The supplied details say it can be activated by a wall switch or an air switch, with the air switch sold separately. Confirm that the control method suits your kitchen and that the required electrical connection is available. The disposal’s power cord is listed as included, but installation needs can vary by kitchen.
Verify what is included and covered
These are bundled sink-and-disposal packages, but accessories differ by model. Compare the listed parts with what you need, including the drain assembly, stopper, connectors, and workstation accessories. The Kore listings state a limited lifetime warranty, while the Bellucci details do not provide a specific warranty term. Check the listing for current availability, exact package contents, and warranty terms before placing an order.
