The Blanco Quatrus R15 U Super Single (model 401518) represents precision German engineering applied to professional-grade kitchen sink design. This undermount single-bowl sink measures 32 inches wide by 18 inches deep with a generous 9-inch bowl depth, crafted from premium 18-gauge, 304-series stainless steel with 18/10 chrome-nickel content. The defining feature is the tight 15mm (0.59-inch) radius corners that balance modern aesthetics with practical cleanability.

This precision DXF template ensures flawless CNC fabrication for granite, quartz, and solid surface installations.
Installation Overview
Installing the Blanco Quatrus R15 (401518) requires attention to its precise geometric specifications, particularly the signature 15mm radius corners that define the Quatrus aesthetic. The sink measures 32 inches overall width by 18 inches depth, with a 30-inch by 16-inch bowl providing ample workspace for large cookware. Our comprehensive DXF template offers four cutout configurations: no-reveal for completely hidden rim installations showcasing the tight-radius corners, 1/8-inch reveal for standard undermount applications with minimal rim exposure, 1/2-inch overhang providing traditional support ledges, and drop-in variant for specialized top-mount scenarios. The sink includes mounting clips and installation template from Blanco, though many fabricators prefer adhesive-based installations for cleaner results. The 9-inch bowl depth accommodates tall stockpots and commercial cookware. Critical installation factors include the rear-positioned drain that maximizes front-to-back bowl usability and under-cabinet storage access, plus the integrated X-pattern drain grooves requiring proper alignment. The tight radius corners demand precise CNC cutting to match the sink profile accurately.
CNC Cutting Notes
CNC fabricators cutting the Quatrus R15 template must pay special attention to the 15mm (0.59-inch) radius corners that distinguish this model from traditional square-corner sinks. These tight-radius corners require precise toolpath generation and appropriate bit selection to achieve smooth, accurate curves matching the sink profile. Choose your reveal variant based on installation methodology - 1/8-inch reveal suits most undermount applications, balancing support with clean aesthetics, while 1/2-inch overhang provides additional bearing surface for thinner materials or installations requiring enhanced edge support. The template's layer structure provides clear CUTOUT geometry for primary cutting and SINK_RIM reference for alignment verification. Compatible with all CNC-cut stone materials using diamond tooling matched to material hardness. The rectangular bowl with 15mm radius corners creates moderate stress concentration compared to full-radius bowls, making proper corner execution critical for long-term installation integrity. The 32-inch width and 18-inch depth represent substantial but manageable cutout dimensions for most CNC machines. Always verify the physical sink's corner radii before cutting, as the template shows 0.25-inch radius while manufacturer specifications indicate 15mm (0.59-inch) - confirm your DXF reflects the correct 15mm radius. Test-fit the actual sink before final installation to verify dimensional accuracy and corner profile matching.
Material Compatibility
The Blanco Quatrus R15 (401518) is fully compatible with all professional countertop materials including granite, engineered quartz, quartzite, marble, solid surface composites, and ultra-compact porcelain slabs. The sink's robust 18-gauge stainless steel construction with premium 18/10 chrome-nickel alloy delivers exceptional strength, corrosion resistance, and thermal shock performance across all material types. Minimum countertop thickness of 2cm is acceptable for most installations, with 3cm recommended for optimal support and longevity, particularly with heavier natural stones. The undermount design with included mounting clips adapts to both natural stone and engineered materials, though many professional fabricators prefer clip-free adhesive installations for cleaner results and easier future service access. The 32-inch by 18-inch footprint creates moderate open span beneath the countertop - ensure continuous substrate support without gaps over the entire sink area. Installations positioned over dishwasher openings or cabinet separations require additional support structure. The tight 15mm radius corners perform well across all materials, though fabricators should ensure corner cutting accuracy matches the sink profile precisely to prevent gaps or stress points during installation. Material thermal expansion compatibility is excellent with stainless steel across all common countertop materials.
