- Spacious 50/50 bowl configuration with 9.5-inch depth accommodates large cookware and pots
- Non-porous surface eliminates bacteria growth and simplifies cleaning with standard household cleaners
- Includes everything needed for installation, saving time and additional hardware costs

The KRAUS Quarza KGD-433B is a premium double bowl kitchen sink designed for homeowners who want the sophisticated look of natural granite without the maintenance headaches. This 33-inch model works perfectly for busy kitchens where multitasking is essential, offering two spacious 50/50 bowls that let you wash and rinse simultaneously without compromising on depth or workspace.
The standout feature is the quartz composite construction, which delivers impressive real-world performance. Made in Italy from natural quartz and premium acrylic resin with metallic particles, this sink resists impact, scratches, and stains while maintaining its elegant appearance. The heat-resistant surface handles cookware up to 500°F without damage, and the non-porous material prevents bacteria growth and food sticking. The sound-absorbing properties create a noticeably quieter kitchen experience compared to stainless steel alternatives.
Design and build quality are excellent. The thick mounting deck creates a polished, finished appearance whether you choose drop-in or undermount installation. Gently rounded corners and a sloped bottom ensure water drains efficiently without pooling, while the smooth surface eliminates crevices where debris accumulates. The 9.5-inch bowl depth provides ample space for large cookware, and the included stainless steel drain assembly with removable strainer prevents clogs.
The primary consideration is installation requirements. While the dual mount design offers flexibility, undermount installation typically requires professional help, which adds labor costs. Additionally, the black finish may show fingerprints and water spots more visibly than lighter colors, requiring regular wiping to maintain appearance. The sink also requires a 36-inch minimum cabinet size, which may not fit all kitchen layouts.
The KRAUS Quarza KGD-433B represents excellent value for homeowners upgrading their kitchen with a durable, stylish double bowl sink that combines aesthetic appeal with practical functionality. The complete installation kit and proven quartz composite construction make this a smart investment for any kitchen renovation.
Dimensions and Capacity
External dimensions: 33 inches length x 22 inches width x 10.125 inches depth. Each bowl: 14.25 inches length x 15.5 inches width x 9.5 inches depth. Minimum cabinet size required: 36 inches. Total weight and volume capacity make this sink suitable for large households and frequent cooks.
Material and Construction
Made from natural quartz composite with premium acrylic resin and metallic particles. Non-porous, hard, smooth surface with color penetrating throughout the material.

Gently sloped bottom with rounded corners for optimal drainage. Includes drain assembly with removable strainer, basket strainer, mounting hardware, installation template, and kitchen towel.
Dual Mount Flexibility
This sink's dual mount design offers two installation pathways. As a drop-in sink, it sits on top of your countertop with the rim visible, working with granite, laminate, solid surface, or quartz counters. As an undermount sink, it installs beneath the countertop for a seamless, modern look that simplifies cleaning by allowing water and crumbs to wipe directly into the bowl.
What's Included
The complete installation kit includes the black granite sink, stainless steel drain assembly with removable strainer, basket strainer option, mounting hardware, cut-out template, and a premium kitchen towel. Professional installation is recommended for undermount applications to ensure proper sealing and support.
Cabinet Requirements
Verify your cabinet opening measures at least 36 inches wide before purchasing. The template included helps ensure accurate countertop cutout dimensions. Pre-drilled faucet hole accommodates standard kitchen faucets, with additional knockout holes available for soap dispensers or other accessories.
Pros

The KRAUS Quarza KGU-413B is a premium undermount kitchen sink designed for homeowners who want the elegant appearance of natural granite without the maintenance headaches. This sink is perfect for those renovating their kitchen or replacing an outdated sink, particularly those who value both aesthetics and functionality in their culinary workspace.
The standout feature of this sink is its advanced quartz composite construction, which combines 80% natural granite with premium acrylic resin to create a surface that looks and feels like natural stone. The metallic particles embedded throughout the material create a sophisticated shimmering effect, while the color-through design ensures the black finish won't fade even with years of daily use. Performance-wise, the non-porous surface resists stains, heat up to 500°F, scratches, and impact better than many natural stone alternatives, making it exceptionally durable for busy kitchens.
The design emphasizes both style and practicality. The undermount installation creates a seamless transition from countertop to sink, eliminating exposed edges that trap debris and simplifying cleanup. The deep bowl measures 28.38 inches long and 8.875 inches deep, providing ample space for large cookware and reducing splatter. The gently sloped bottom and rounded corners promote optimal drainage, while the sound-absorbing material minimizes noise from dishes and garbage disposal, creating a more pleasant kitchen environment.
One consideration is that this single bowl model may feel limiting if you frequently need separate washing and rinsing stations. Additionally, proper undermount installation requires professional expertise to ensure adequate support and waterproofing, which adds to the overall project cost beyond the sink purchase itself.

The deep bowl (9-1/2 inches) easily accommodates tall stockpots and baking sheets, while the anthracite color hides water spots and adds a sophisticated touch.
Build quality is top-notch: the sink feels solid and heavy, and the composite material resists chipping even when heavy cookware is dropped. However, the sink does not include a basket strainer or installation clips, so those must be purchased separately. Additionally, the 36-inch minimum cabinet requirement may limit options for smaller kitchens.
One potential drawback is the price, which is higher than many stainless steel alternatives. Yet the durability, ease of maintenance, and lifetime warranty justify the investment for serious cooks. The sink also requires careful handling during installation due to its weight, but professional installation is recommended.

What to Look for When Buying a Granite Composite Kitchen Sink
Material Composition and Durability
Granite composite sinks are engineered from natural granite crystals combined with acrylic or polyester resin, creating a non-porous surface that resists stains, scratches, and thermal shock. The higher the percentage of natural granite (typically 80% or more), the more durable and heat-resistant the sink becomes. Look for sinks that are colored throughout their entire thickness, not just on the surface, so minor scratches won’t reveal a different color underneath.
Premium composite materials also minimize noise and vibration when water runs or dishes clatter, making your kitchen a quieter, more pleasant space. Check product specifications for heat resistance ratings; most quality granite composite sinks can withstand temperatures up to 356 degrees Fahrenheit without discoloration or damage.
Bowl Configuration and Depth
Single-bowl sinks offer maximum usable space for washing large pots and pans, while double-bowl designs provide dedicated zones for washing and rinsing. Bowl depth matters significantly for functionality: deeper bowls (8.5 inches or more) accommodate larger cookware and reduce splashing. Consider your cooking style and household size when choosing between configurations.
Many modern granite composite sinks feature workstation designs with front and back ledges that accommodate sliding accessories like cutting boards, colanders, and drying racks. These convertible designs maximize counter space and add versatility without requiring separate purchases. Our buying guide covers all the factors that impact long-term satisfaction with your sink investment.
Installation Type and Cabinet Compatibility
Undermount sinks install from below the countertop for a seamless, modern appearance that simplifies cleaning since debris doesn’t collect on the rim. Drop-in (topmount) sinks rest on top of the counter and are easier to install but create a visible ledge where grime can accumulate. Some models support both installation methods, giving you flexibility based on your countertop material and existing cabinet setup.
Always verify the minimum cabinet width required; most 33-inch sinks need at least a 36-inch base cabinet. Check the drain opening size (typically 3.5 inches) to ensure compatibility with your garbage disposal or drain assembly. The package should include a cutout template and installation hardware to simplify the process.
Included Accessories and Warranty Coverage
Quality granite composite sinks often bundle valuable accessories like solid wood or composite cutting boards, foldable drying racks, protective bottom grids, and drain assemblies. These extras eliminate the need for separate purchases and ensure all components are designed to work seamlessly together. Verify what’s included before buying to avoid unexpected additional costs.
Warranty coverage protects your investment against manufacturing defects. Look for sinks backed by at least a one-year limited warranty; some premium brands offer longer coverage. Farmhouse-style sinks often feature similar material quality and warranty standards, so comparing options across styles can help you identify the best value in the market.
Final Thoughts
Granite composite sinks deliver the aesthetic appeal of natural stone with practical durability that handles years of daily use without fading, staining, or chipping. If you want a workstation sink with flexible accessories and modern design, the FULORNI 33-Inch Black Granite Composite Kitchen Sink offers excellent value with premium materials and a full accessory package. For those seeking Italian-crafted quality with customizable options, the Ruvati 33-Inch Black Granite Undermount Workstation Sink combines superior granite composition with a patented silicone grid and over 40 compatible accessories for endless kitchen configurations.

Frequently Asked Questions
Are granite composite sinks better than stainless steel? Granite composite sinks resist scratches and stains more effectively than stainless steel and require less maintenance. However, they’re heavier and more expensive upfront. Both materials are durable; your choice depends on your aesthetic preference and lifestyle. Stainless steel suits minimalist kitchens, while granite composite complements traditional and contemporary designs equally well.
Can you put hot pans directly in a granite composite sink? Yes, most quality granite composite sinks are heat-resistant up to 356 degrees Fahrenheit. However, using a protective bottom grid (typically included) prevents thermal shock and extends the sink’s lifespan. Avoid placing extremely hot cookware directly on the surface repeatedly, as sustained high temperatures can occasionally cause minor discoloration on lower-quality composites.
How do you clean and maintain a granite composite sink? Daily cleaning requires only warm water and mild dish soap with a soft cloth or sponge. Avoid abrasive scrubbers and acidic cleaners like vinegar or lemon juice, which can dull the finish over time. For stubborn stains, use baking soda paste or a specialized granite cleaner. The non-porous surface prevents bacterial growth and makes maintenance significantly easier than porous natural stone.
What’s the difference between granite composite and quartz composite sinks? Granite composite contains 80% or more natural granite crystals, making it harder and more heat-resistant. Quartz composite typically contains a lower percentage of stone and more resin, offering different aesthetic options but potentially less durability. Both are excellent choices in 2026; your decision should be based on color preference, budget, and the specific features you value most for your kitchen workflow.
