The ALFI Brand AB3320SB-W stands out among 33-inch farmhouse sinks with its exceptionally deep 20.875-inch front-to-back dimension. This extra depth translates to a massive 31 x 18-inch bowl opening, making it one of the largest single bowl fireclay sinks available in this width class. The Italian-manufactured sink combines traditional craftsmanship with modern proportions, ideal for contemporary kitchens requiring maximum workspace. Its reversible design offers installation flexibility with different apron profiles on each side. Our professional DXF template package provides four precision-engineered cutting variants that accommodate this sink's unique depth while maintaining structural integrity across all countertop materials from granite to ultra-compact surfaces.
Installation Overview
The AB3320SB-W's 20.875-inch depth presents unique installation considerations compared to standard 18-inch farmhouse sinks. This additional depth requires careful cabinet planning—the minimum 36-inch cabinet width must extend at least 24 inches front-to-back to accommodate the sink body and provide adequate support structure. The exceptional 31 x 18-inch bowl cutout removes substantial countertop material, making proper support critical especially in quartz and marble installations. Fabricators should plan reinforcement blocking that extends the full depth of the sink, positioned to transfer the 80-90 pound sink weight to solid cabinet walls rather than countertop edges. The reversible apron design allows orientation choice during installation; one side features sharper geometric lines while the reverse offers softer curves. When templating, account for the 8.9-inch vertical bowl depth which provides excellent capacity but may impact faucet reach and spray patterns. The white glaze finish extends to all surfaces including the underside, allowing various mounting techniques. Standard 3.5-inch center drain positions toward the rear of the bowl due to the extended depth, optimizing cabinet storage below. This depth also accommodates extra-deep storage or garbage disposal units that would conflict with shallower sinks.
CNC Cutting Notes
CNC programming for the AB3320SB-W demands special attention to the 31 x 18-inch bowl dimensions—among the largest single bowl cutouts in this sink category. The extended 18-inch depth requires careful workpiece securing to prevent deflection during cutting, especially when working with large-format slabs. Start with the no-reveal variant at full 31.0 x 18.0-inch dimensions, using 0.25-inch radius corners that require precise tool control in hard materials. For granite cutting, utilize sequential depth passes rather than full-depth plunge cuts to maintain accuracy across the extended cut path. The eighth-reveal option (30.75 x 17.75 inches) creates a substantial lip while still removing significant material—verify material thickness around cutout meets minimum 2-inch specification for structural integrity. Half-overhang configuration at 30.0 x 17.0 inches is particularly important for this sink, as the large cutout benefits from maximum perimeter support in quartz and marble. When programming corner approaches, reduce feed rates to 40-50% of straight-line speeds to prevent tool deflection that compounds over the long cut paths. The drop-in variant requiring full 33 x 20.875-inch opening demands precise front edge control for farmhouse apron alignment—consider using edge-finding routines to establish accurate reference points.
Material Compatibility
The AB3320SB-W's large bowl cutout presents both opportunities and challenges across different countertop materials. Granite handles the 31 x 18-inch opening excellently, as natural stone's compressive strength easily spans this dimension in standard 3cm thickness. The template's reveal options allow fabricators to optimize support based on granite's natural fissure patterns and crystal structure. Quartz installations require careful analysis—the large cutout removes substantial engineered material, making the half-overhang variant (30.0 x 17.0 inches) nearly mandatory to maintain adequate perimeter material for structural integrity and warranty compliance. Marble fabricators should consider the stone's veining orientation when positioning this sink, as the extended depth affects how veining flows around the cutout; use the eighth-reveal option to maximize remaining material strength. Quartzite cutting demands premium diamond tooling due to the extended cut length through this extremely hard material—budget for higher tool wear on this template. Soapstone works beautifully despite being softer, as its natural flexibility accommodates the sink's weight distribution across the large bowl area. Porcelain slab fabricators will appreciate how the template's precise dimensions suit large-format cutting, though the extended depth requires careful support during and after cutting to prevent slab flexure.
