The Alpha International G3218S offers expanded capacity in a single bowl configuration, measuring 32 inches wide by 18 inches deep with exceptional 9-inch bowl depth. This oversized granite composite undermount sink accommodates large cookware, baking sheets, and roasting pans with ease, making it ideal for serious home cooks and professional-style kitchens.

Requiring a 35-inch minimum base cabinet, this sink maximizes functional capacity while maintaining the durability and aesthetic appeal of premium granite composite construction.

Installation Overview
Installing the G3218S large single bowl sink requires attention to structural support due to the extended cutout dimensions. The template provides four variants: no-reveal for flush edge-to-edge fitting, 1/8-inch reveal for professional undermount installation with visible rim protection, 1/2-inch overhang for increased countertop support over the sink rim, and drop-in configuration for top-mount applications. Given the sink's substantial size, ensure your base cabinet provides adequate internal clearance for both the sink bowl and plumbing connections. The 9-inch bowl depth means the sink bottom may sit lower than standard models, requiring careful measurement of cabinet interior height and drain positioning. Use robust undermount clip systems rated for heavy loads—minimum eight clips evenly distributed around the perimeter. The large cutout removes significant countertop material, so verify slab structural integrity and consider additional support rails or corbels for installations in natural stone exceeding 8 feet in length. Position clips away from corners to avoid stress concentration points in the stone.
CNC Cutting Notes
The G3218S presents straightforward CNC programming due to its single bowl geometry without complex multi-bowl intersections. The larger cutout dimension requires verification that your CNC table and gantry can accommodate the full travel path without interference. Use appropriate fixturing to secure the slab during cutting, as the large cutout creates significant vibration potential. Select a 3/8-inch diameter bit for the corner radius, maintaining consistent feed rates throughout the cut to avoid witness marks at speed transitions. The single continuous perimeter allows for efficient one-pass cutting with minimal tool changes. Program your toolpath to start and end at the sink's rear edge where any minor witness marks will be hidden from view. For materials prone to chipping like natural granite, implement a scoring pass at 1/8-inch depth before full-depth cutting to minimize edge damage.
Material Compatibility
This oversized single bowl template excels in premium countertop installations where maximum sink capacity is desired. Granite countertops benefit from the granite composite sink's matching thermal properties and complementary aesthetics. The large cutout showcases beautiful stone patterns on the surrounding counter surfaces while the composite sink provides practical durability advantages. In quartz installations, the substantial bowl capacity pairs well with modern kitchen designs emphasizing clean lines and functional workspace. Marble fabricators can confidently install this composite sink knowing it won't be damaged by the acidic cleaners and foods that can etch natural marble. The undermount style creates seamless integration with any countertop material, allowing water and debris to be swept directly into the sink without catching on raised edges.
