The Blanco Quatrus R15 32 represents the pinnacle of modern kitchen sink engineering, combining generous capacity with precision German craftsmanship. This super single bowl measures 32 inches wide by 18 inches deep, featuring a spacious 30x16 inch basin that handles oversized cookware with ease. Fabricated from premium 18-gauge 304 stainless steel with sound-dampening technology, it delivers both durability and quiet operation. Our professional-grade DXF template provides four installation variants optimized for granite, quartz, and marble countertops, ensuring perfect undermount installations every time. The distinctive 15mm radius corners create the perfect balance between modern aesthetics and practical cleanability.
Installation Overview
Installing the Blanco Quatrus R15 32 requires a 36-inch minimum cabinet width and careful attention to support requirements given the sink's substantial capacity. The 18-gauge stainless steel construction provides excellent rigidity while the pre-installed sound dampening pads reduce operational noise significantly. Our template suite includes four professionally engineered variants: the no-reveal option for flush installations where the countertop edge meets the bowl precisely, the 1/8-inch reveal for traditional undermount applications that create a small shadow line, the 1/2-inch overhang for thicker 3cm stone materials requiring additional support surface, and a drop-in configuration for top-mount scenarios. The rear-positioned drain maximizes usable bowl space and creates valuable cabinet storage area below. When templating, pay special attention to the X-pattern drain grooves molded into the basin floor - these functional channels direct water flow and should align with your client's sink workflow. The 15mm radius corners require precise CNC programming to achieve the gentle curve that defines the Quatrus aesthetic. This is not a tight-radius sink, making it more forgiving during fabrication while still delivering contemporary styling.
CNC Cutting Notes
CNC programmers should approach the Quatrus R15 32 cutout with attention to the 15mm (approximately 0.625-inch) corner radius specification. This generous radius reduces bit deflection and chipping risk, particularly important in brittle materials like quartzite. Program a three-pass approach for optimal results: roughing pass at 85% feed rate to remove bulk material, semi-finish pass at 70% to establish dimensional accuracy, and final pass at 50% feed rate for mirror-smooth edges. The larger 32-inch span requires additional care on CNC tables to prevent material movement during cutting - use a minimum of six vacuum zones and verify seal before starting. For the corner radii, slow your feed rate by an additional 20% and enable corner rounding algorithms in your CAM software to prevent flat spots. The stainless steel sink bowl's tight tolerances demand equally precise cutouts - hold ±0.008-inch throughout the cut. Polish undermount edges to 600-grit for optimal adhesive bonding with silicone. The template's layer structure separates reference lines from cut paths, simplifying toolpath generation and reducing programming errors.
Material Compatibility
The Quatrus R15 32 template performs exceptionally well across all countertop materials commonly used in residential and commercial applications. In granite installations, the 32-inch width provides stunning visual impact in large kitchen islands while the deep bowl accommodates commercial-sized cookware. Quartzite fabricators should use premium diamond tooling and increase corner dwell time to prevent micro-fracturing in these ultra-hard materials. The sink pairs beautifully with engineered quartz, where the stainless steel's thermal properties complement quartz's stability. When working with marble, the large cutout requires careful structural assessment - maintain minimum 4-inch edge distances and consider steel reinforcement bars for overhangs exceeding 10 inches. The 9-inch bowl depth works in both 2cm and 3cm materials, though 3cm installations provide superior visual proportion. For ultra-compact surfaces like Dekton or Neolith, the Quatrus R15's weight distribution and mounting clip system provide secure long-term installation. The sink's professional-grade construction makes it equally at home in Calacatta marble luxury kitchens or commercial-grade granite prep areas.
