BLANCO Performa SILGRANIT 33" 50/50 Double Bowl Undermount Kitchen Sink

Equal Basin Division Maximizes Dual-Task Efficiency

Streamline your kitchen workflow with the BLANCO Performa 33" 50/50 Double Bowl Undermount, a sink that pairs equal basin sizing with the clean aesthetics of rimless installation. Built from 80% natural quartz sand—the mineral foundation that gives granite its legendary hardness—this German-manufactured SILGRANIT composite sink withstands the physical demands of daily cooking while maintaining its sophisticated appearance. The undermount configuration eliminates visible rim edges, creating smooth countertop-to-basin transitions that highlight premium stone surfaces while preventing the dirt accumulation that occurs around raised sink perimeters. The symmetrical 50/50 division provides two identical 15" x 18" basins, each with exceptional 10" depth that accommodates stacked dishes, tall cookware, or large mixing bowls. The Anthracite coloration extends completely through the composite material, preventing visible wear even when surface scratches occur during years of intensive use.

Symmetrical Workspace for Balanced Kitchen Operations

Benefit from equal basin sizing that provides identical capacity on both sides, eliminating the workspace compromises inherent in asymmetrical configurations. Each 15" x 18" basin handles dinner plates, mixing bowls, and standard cookware with equal facility, while the impressive 10" depth—deeper than many competing sinks—provides substantial vertical clearance for washing tall stockpots or stacking multiple dish loads. The SILGRANIT composite's non-porous molecular architecture blocks liquid penetration, preventing the bacterial colonization and odor development that plague porous sink materials. The material's thermal stability accepts hot cookware transferred directly from active cooking surfaces without suffering the warping or discoloration that affects temperature-sensitive materials. The smooth composite finish releases utensil marks and food residues through standard cleaning, maintaining visual appeal without demanding specialized maintenance products. The undermount installation facilitates direct countertop wiping into either basin, streamlining cleanup during meal preparation.

Common Questions Answered

Why choose 10" basin depth over standard 8" or 9" depths?

The 10" basin depth provides significant functional advantages that become apparent during daily kitchen use. This additional vertical clearance allows you to stack substantially more dishes in each basin before reaching the rim, reducing the number of washing cycles required after large meals or entertaining events. The extra depth also accommodates taller cookware like stockpots and pasta pots without the rim interference that occurs in shallower basins, making it easier to fill these items directly in the sink rather than transferring water from elsewhere. The increased depth reduces splashing during vigorous washing or when filling large containers, keeping surrounding countertops drier and reducing cleanup requirements. For those who hand-wash dishes, the deeper basins allow you to fill one side with soapy water to a level that fully submerges plates and cookware, improving washing efficiency compared to shallower basins where items protrude above the waterline.

How does the Performa collection balance performance and value?

The Performa collection represents BLANCO's approach to delivering core SILGRANIT performance in straightforward designs that prioritize functional efficiency over decorative embellishments. While utilizing identical 80% quartz composite formulation as premium BLANCO collections, Performa focuses on proven basin geometries and standard installation methods that reduce manufacturing complexity without compromising material quality or durability. This design philosophy results in sinks that deliver the stain resistance, thermal stability, and longevity expected from SILGRANIT composite while maintaining accessible pricing that suits budget-conscious kitchen renovations. The collection proves particularly appropriate for rental properties, investment homes, or primary residences where owners prioritize long-term durability and low maintenance over cutting-edge design aesthetics, as the straightforward styling remains visually appropriate across changing design trends.
