The Blanco 440063 Performa Cascade in Cafe Brown combines sophisticated color with innovative dual-depth basin design.

Installation Overview
Installing the Performa Cascade 440063 requires understanding the cascade ledge's impact on workflow and drain placement. The sink's 32-inch width and 19.5-inch depth require a minimum 36-inch base cabinet for adequate support. Interior bowl dimensions of 30x17.5 inches provide substantial workspace, divided by the integral cascade ledge that runs the length of the basin. The left section maintains full 10-inch depth for heavy-duty washing, while the right section features a 7.75-inch depth platform perfect for the mesh colander or air-drying dishes. At 45 pounds empty weight, the sink demands robust cabinet support and proper countertop thickness. Undermount installation uses clips attached to the sink rim and adhesive bonding to the stone underside. Position the 3.5-inch drain in the deeper left section for optimal water evacuation. The SILGRANIT II rim is 1.5 inches deep, providing ample material for clip engagement. Fabricators should polish the cutout edge to 400-grit minimum for professional results. The Cafe Brown finish may show water spots more readily than darker colors, so recommend customers dry the sink after use.
CNC Cutting Notes
CNC programming for the 440063 follows standard single-bowl protocols adapted for the generous 30x17.5-inch interior. Our template includes four variants optimized for different installation preferences. The no-reveal variant cuts to exact bowl dimensions (30x17.5 inches) for installations where the rim sits flush against the countertop underside. The 1/8-inch reveal variant reduces the cutout to 29.75x17.25 inches, creating a small stone lip around the opening. The 1/2-inch overhang variant cuts 29.0x16.5 inches for more dramatic reveal and simplified clip installation. The drop-in variant cuts the full 32x19.5-inch perimeter for top-mount applications, though this installation style is uncommon for Performa Cascade models. All variants incorporate 0.75-inch corner radii matching the SILGRANIT molding. Tool paths should maintain 0.010-inch dimensional tolerance on critical measurements. Use waterjet or diamond-tooled CNC for granite and quartz cutting, with 400-grit edge polishing for undermount applications. The large cutout dimensions provide generous space for clip placement and installation adjustments.
Material Compatibility
The Performa Cascade's 45-pound installed weight and large cutout dimensions require substantial countertop support. Three-centimeter quartz provides ideal rigidity and strength for undermount installation, with the material thickness matching well to the 1.5-inch rim depth. Two-centimeter quartz installations should include support rails or build-up around the cutout perimeter to prevent flex. Granite slabs of 2cm or 3cm work excellently, though verify adequate material remains around the 30x17.5-inch opening - minimum 4 inches to countertop edge is recommended. The Cafe Brown SILGRANIT finish coordinates beautifully with warm-toned granites like Santa Cecilia, Giallo Ornamental, and Colonial Gold. For cooler quartz colors, the Cafe Brown creates attractive contrast. The sink's heat resistance to 536°F pairs well with granite's thermal properties. Solid surface installations require minimum 3cm thickness to support the undermount weight. Avoid installations in tile or thin materials that cannot provide adequate structural support for the basin and cascade ledge.
