Extra-Large Single Bowl Maximizes Kitchen Workspace
Transform your kitchen efficiency with the BLANCO Diamond 33.5" Super Single, a dual-mount kitchen sink that delivers maximum uninterrupted workspace through its expansive single bowl design. Crafted from 80% natural quartz sand—the hardest component of natural granite—this German-engineered SILGRANIT composite sink provides extraordinary durability that withstands heavy cookware, hot bakeware, and the demands of serious cooking. The impressive 30.5" x 16.5" interior basin with 9.5" depth creates an unobstructed workspace that easily accommodates the largest cookware, commercial-style baking sheets, and oversized roasting pans without the divider interruptions found in double bowl configurations. The rich Anthracite finish is colored throughout the entire material, ensuring consistent appearance that resists fading and discoloration over years of use.
Uninterrupted Basin Space for Professional Cooking
Experience the freedom of a truly expansive single bowl that eliminates the workspace limitations of divided sinks. The non-porous SILGRANIT surface technology naturally repels stains, bacteria, and odors without requiring special cleaners or maintenance treatments, while the smooth stone finish effortlessly releases scuff marks from utensils and stains from food and drinks. The heat-resistant composite construction safely accommodates hot pots and pans directly from the stovetop, protecting your sink from thermal shock damage. The versatile dual-mount design provides installation flexibility for both drop-in and undermount applications, while the pre-drilled single faucet hole includes six knockout options for extensive accessory integration including soap dispensers, beverage faucets, or pot fillers.

Common Questions Answered
What advantages does a super single bowl provide over double bowl configurations?
The super single bowl design eliminates the workspace limitations inherent in divided sink configurations, providing uninterrupted basin space that proves invaluable for serious cooking and large-scale meal preparation. The expansive 30.5" x 16.5" basin easily accommodates oversized items like turkey roasters, commercial half-sheet pans, and large stockpots that simply cannot fit in either side of a divided sink, regardless of bowl split ratio. This unobstructed workspace also simplifies washing large cutting boards, cookie sheets, and serving platters that would need to be angled awkwardly in double bowl sinks. The generous 9.5" depth provides ample vertical clearance for filling tall stockpots, washing stacked dishes, or soaking large items without splashing, while the single bowl configuration allows you to use the entire basin capacity for any task rather than being constrained by fixed bowl divisions.
How does the extensive faucet hole configuration enhance functionality?
The pre-drilled single faucet hole with six additional knockout options provides exceptional flexibility for creating a fully integrated kitchen workstation tailored to your specific needs. This extensive configuration allows you to add multiple accessories beyond the standard faucet and soap dispenser, such as a dedicated beverage faucet for filtered water, a pot filler for convenient stockpot filling, or additional accessories like air switches for garbage disposals. The generous knockout options prove particularly valuable in open-concept kitchens where the sink serves as a central hub for cooking, cleaning, and beverage service, allowing you to consolidate multiple functions in one location rather than requiring separate installations throughout the kitchen. This flexibility ensures your sink can adapt to changing needs over time as you add new appliances or upgrade existing fixtures.
