Next step: Run a DXF check, compare related templates, and keep the current manufacturer spec with the job packet.
Template decision guide
Should you use the ALFI Brand AB3020SB-W 30 Fireclay Undermount 30" Single Bowl Undermount Sink Cutout DXF template?
Use the template page to shortlist a production file, then verify the exact model, variant, and machine workflow before cutting.
Best fit
ALFI Brand AB3020SB-W 30 Fireclay Undermount 30" Single Bowl Undermount Sink Cutout is most useful when the product, manufacturer, model, install type, and variant match the job you are fabricating.
What to compare

The ALFI Brand AB3020SB-W bridges traditional fireclay craftsmanship with contemporary undermount installation methods, offering a generous 30-inch single bowl in brilliant white. This Italian-made fireclay sink features reversible design with smooth and fluted apron options, though when installed as undermount the decorative apron becomes a hidden structural element. The expansive bowl dimensions of 27.84" x 18.19" make this one of the largest single-bowl undermount fireclay options available, providing exceptional capacity for commercial-style residential kitchens. With 8.9 inches of depth, this sink accommodates oversized cookware while the fireclay construction delivers superior heat resistance and durability compared to stainless alternatives. For fabricators, this template provides precision-verified dimensions for a unique product category, the large-format fireclay undermount sink that combines artisanal material quality with modern installation aesthetics.
Installation Overview
Installing the AB3020SB-W as undermount requires specialized techniques due to the sink's substantial weight and fireclay construction. Unlike typical stainless undermount sinks, this 80-90 pound fireclay unit demands robust support beyond standard undermount clips. Many fabricators employ a combination of clips and silicone adhesive for secure attachment, while some installations benefit from additional cabinet-mounted supports directly beneath the bowl. Our template package includes four cutout variants optimized for different installation requirements: no-reveal (27.84" x 18.19") maximizes sink lip contact with the stone for maximum support, 1/8" reveal (27.59" x 17.94") provides the industry-standard aesthetic while maintaining substantial support, 1/2" overhang (26.84" x 17.19") showcases the sink's substantial depth and works with thicker stone edges, and drop-in conversion (29.75" x 20.875") enables top-mount installation if undermount proves impractical. The sink requires a minimum 33-inch cabinet base, though 36-inch cabinets are strongly recommended given the 20.875-inch front-to-back dimension that exceeds most standard sink depths. The exceptional bowl depth of 8.9 inches provides 15% more capacity than typical 8-inch sinks, appealing to serious home cooks but requiring verification of adequate cabinet interior height for plumbing and disposal installation.
CNC Cutting Notes
Programming the AB3020SB-W cutout presents unique challenges due to the large opening dimensions and weight implications for the finished installation. The 27.84" x 18.19" bowl dimensions create a substantial cutout that removes significant material, generating considerable dust and requiring robust vacuum systems for clean operation. Use a 1/2" diameter carbide spiral upcut bit for optimal performance, though 5/8" bits can reduce cycle time on softer materials like marble. The irregular dimension specifications (27.84" vs round numbers) suggest these measurements derive from actual product sampling rather than theoretical design, making dimensional accuracy critical. Feed rates should be conservative given the large opening size: 80-100 IPM for granite and quartzite, 120-140 IPM for quartz engineered stone, and 100-120 IPM for marble to prevent excessive vibration in the large free-span area being cut. The 0.25" corner radius requires standard tooling and provides adequate radius for proper sealing without specialized micro-tooling. For undermount installations, complete edge polishing to 180-grit minimum is essential across the entire cutout perimeter, as all edges will be visible from above. Consider programming a ramped entry rather than plunge cut to reduce stress on the slab during initial tool engagement. The substantial removed section can be repurposed for template material, cutting boards, or small projects, helping offset material costs on this large-format cutout.
Material Compatibility
The AB3020SB-W's white fireclay construction and substantial dimensions make it ideal for high-end residential and light commercial applications across diverse stone selections. For granite installations, this sink pairs dramatically with premium dark stones like Volga Blue, Black Galaxy, or Cosmic Black, where the generous white bowl creates stunning visual impact. Lighter granite varieties like Colonial White, River White, or Bianco Antico create cohesive all-light palettes popular in coastal and transitional designs. The large bowl dimensions suit expansive kitchen islands fabricated from exotic granites like Blue Bahia, Fusion, or Labradorite where the sink becomes a functional focal point. Quartz fabricators will find this sink specification-matches premium kitchen projects featuring Caesarstone Calacatta Nuvo, Silestone Eternal Calacatta Gold, or Cambria Brittanicca, where the substantial sink complements equally substantial countertop investments. The fireclay's superior heat resistance makes this sink particularly appropriate for quartzite installations where thermal shock remains a concern with other materials. Marble fabricators working with Calacatta, Statuario, or premium Carrara will appreciate how the white fireclay maintains aesthetic cohesion while providing far superior stain and scratch resistance compared to marble itself. Concrete countertops gain refined contrast when paired with this traditional white sink. The substantial weight and size demand equally substantial stone thickness, making this sink most appropriate for 3cm materials with potentially enhanced support requirements for 2cm installations. Standard fireclay tolerances of ±1/8" necessitate templating from actual sink units for high-value installations.
Where to Buy
The ALFI Brand AB3020SB-W is available through specialty plumbing distributors and select retailers, though availability is more limited than standard farmhouse models due to the undermount configuration. Primary sources include The Sink Boutique, ALFI Brand's direct distribution network, Home Depot (select markets), and specialty kitchen retailers catering to premium residential projects. Online availability through Amazon and build.com fluctuates based on import inventory levels. Retail pricing typically ranges $650-$850, reflecting the premium positioning of large-format fireclay undermount sinks. The reversible apron feature (smooth/fluted) adds manufacturing complexity and cost compared to single-finish alternatives. Fabricators should establish relationships with distributors who understand the product's unique characteristics and can provide technical support for undermount installation techniques with fireclay materials. Lead times from Italy typically run 4-6 weeks under normal conditions, with potential extensions during peak building seasons or international shipping disruptions. When quoting installations, emphasize the sink's substantial weight and unique installation requirements, potentially recommending site visits to verify adequate cabinet support structures before committing to undermount installation versus alternative mounting methods. The AB3020SB-W represents a premium specification that appeals to discerning homeowners seeking fireclay quality with contemporary undermount aesthetics.
