The Alpha International U103 K Series represents premium compact sink design in a perfect 16-inch square format. This commercial-grade 304 stainless steel undermount sink features 18-gauge construction with a premium satin finish, delivering professional quality in a space-efficient footprint. The 14x14 inch interior bowl provides substantial capacity despite the compact exterior dimensions, while the 8-inch depth accommodates bar and prep sink applications. Designed for 18-inch minimum base cabinets, the U103 fits island installations, wet bars, butler's pantries, and secondary prep areas where space is at a premium. The DXF template includes four installation variants for versatile fabrication options.
Installation Overview
The U103's compact square geometry simplifies installation while requiring careful attention to cabinet clearance and plumbing access. The template provides four essential variants: no-reveal for flush bowl-to-countertop alignment, 1/8-inch reveal for standard professional undermount installation, 1/2-inch overhang for maximum countertop coverage, and drop-in variant for top-mount applications. The square format creates equal stress distribution across all edges, making it particularly suitable for thin profile countertop materials like 2cm quartz or granite. When installing in islands or peninsula applications, position the sink to allow adequate clearance for faucet installation and user access. The 18-gauge stainless steel construction requires minimum four undermount clips evenly distributed around the perimeter. For bar sink applications, consider the bowl's 8-inch depth when selecting faucet height to ensure proper clearance and functionality. The square corners specified at 0.0 radius create crisp 90-degree angles, though some fabricators may choose to add a small radius for easier cleaning.
CNC Cutting Notes
Programming the U103 template offers straightforward square geometry that executes efficiently on any CNC platform. The specified corner radius of 0.0 indicates sharp 90-degree corners, which can be achieved by programming perpendicular line intersections. However, many fabricators prefer adding a small 1/8-inch radius at corners to facilitate easier bowl cleaning and reduce potential stress concentration in the stone. If maintaining sharp corners, ensure your tool path creates clean intersections without over-cutting or leaving witness marks. Use a 3/8-inch or 1/2-inch diameter bit for efficient cutting in the straight runs. The compact 16x16 inch footprint allows for optimal material utilization when laying out multiple sinks or combining with other cutouts on a single slab. Set appropriate feed rates for your material—stainless steel sinks pair well with all countertop materials and standard cutting parameters apply. Always run simulation to verify corner execution matches your intended installation appearance.
Material Compatibility
The U103 stainless steel sink template works seamlessly with all countertop materials, offering particular advantages in modern and contemporary kitchen designs. In granite installations, the brushed stainless finish provides attractive contrast against polished stone surfaces while matching stainless appliances. Quartz fabricators appreciate the sink's consistent dimensions and ease of integration with engineered stone's tight tolerances. The compact square format makes it ideal for waterfall edge island installations where the sink is positioned away from the main work area. Marble countertop installations benefit from stainless steel's resistance to etching and staining, providing durability the natural stone lacks. The undermount style creates seamless transitions ideal for concrete countertops, allowing the industrial aesthetic to flow uninterrupted. The 18-gauge commercial construction ensures long-term performance across all material pairings.
