Description
The prep sink full setup template represents the complete accessory package for dedicated food preparation areas in modern luxury kitchens. This professional DXF template provides countertop fabricators with the exact three-hole pattern needed to accommodate a prep sink faucet, soap dispenser, and garbage disposal air switch in one coordinated layout. Prep sinks serve as secondary work stations for vegetable washing, beverage prep, and other kitchen tasks that benefit from dedicated plumbing separate from the main sink. Equipping these prep areas with a full complement of fixtures creates maximum functionality in a compact footprint. This template delivers three precisely positioned 1.375-inch diameter holes with industry-standard spacing: the center faucet hole flanked by soap dispenser and air switch holes at 4-inch and 3-inch spacing respectively. The 20-inch overall card width accommodates this complete assembly while fitting comfortably above typical 15-inch to 18-inch prep sink bowls. This configuration is particularly popular in island installations, butler pantries, outdoor kitchen prep areas, and wet bars where full functionality is desired without the visual bulk of a larger faucet spread. The compact spacing allows fabricators to position all three accessories within the limited deck space typically available around smaller prep sink cutouts.

Installation Overview
Installing the prep sink full setup requires careful planning to maximize the limited deck space around smaller sink bowls. Center the faucet hole over the prep sink centerline, positioned 1.5 to 2 inches from the sink front edge. This forward positioning ensures adequate spout reach into the typically shallow prep sink basin while leaving room behind the faucet for the soap dispenser and air switch. All three holes should be drilled at the standard 1.375-inch diameter perpendicular to the countertop surface. Position the soap dispenser hole 4 inches center-to-center from the faucet, typically to the left for right-handed users accessing the main sink area. The air switch hole positions 3 inches from the soap dispenser, creating a compact linear arrangement that fits within typical prep sink deck constraints. Verify adequate below-deck clearance for all three components, as prep sink cabinets are often smaller than main sink bases. The soap dispenser requires vertical clearance for its reservoir bottle, the faucet needs clearance for supply line connections and mounting hardware, and the air switch requires routing space for its pneumatic tubing to the disposal power module. When working with undermount prep sinks in stone materials, maintain at least 2 inches of material between hole edges and the sink cutout edge to preserve structural integrity and prevent stress cracks.
CNC Cutting Notes
This compact three-hole DXF template optimizes for efficient CNC programming and execution across multiple fabrication methods. The file imports cleanly into all standard CNC software platforms with holes defined as simple circles on organized layers, compatible with both router and waterjet cutting operations. For CNC router work on stone materials, program a multi-stage drilling approach: pilot hole at center, rough drill to 80 percent depth at production feed rate, finish pass to final depth at reduced feed for superior edge quality. Recommended spindle speeds for granite and engineered quartz range from 9,000 to 13,000 RPM with plunge rates of 18-28 inches per minute using quality diamond core tooling. The 1.375-inch hole diameter represents the optimal size for both tool performance and hardware compatibility. For waterjet operations, these holes cut quickly with minimal taper concerns due to their small diameter. Program holes in sequence from left to right or right to left to minimize rapid traverse time between features. The template uses standard coordinate referencing making it simple to nest within your larger countertop layout. When fabricating prep sink installations in islands or other locations where both countertop surfaces are visible, consider through-cutting from the top surface to maintain cleanest edge quality on the visible side. Always verify programmed hole positions with digital layout tools before cutting, as prep sink installations often involve tight spacing with minimal error tolerance.
Material Compatibility
This prep sink full setup template functions reliably across all countertop substrate types with proper tooling and technique selection. Natural stone materials including granite, marble, quartzite, and soapstone deliver excellent results with diamond core bits or CNC diamond router tooling. These materials require adequate water cooling during drilling to control heat and prevent thermal shock cracking, particularly important in the thinner material sections typical around smaller prep sink cutouts. Engineered quartz surfaces like Caesarstone, Cambria, and Silestone work well with this template using premium diamond tooling specifically formulated for quartz fabrication. Reduce feed rates slightly compared to natural granite to compensate for quartz higher hardness and abrasiveness. Solid surface materials including Corian, Staron, and Hi-Macs provide the most forgiving substrate for this hole pattern. Standard carbide tooling delivers clean results without the need for water cooling, and the material homogeneous structure eliminates concerns about hidden voids or weak grain directions. For laminate countertops, execute this pattern with proper backing support to prevent delamination around hole perimeters. Concrete countertops require diamond core bits and patient drilling technique with minimal pressure to avoid aggregate dislodgment or surface chipping. Ultra-compact surfaces like Dekton and Neolith work with this template using specialized tooling rated for these extremely hard materials, though expect slower cutting speeds and more frequent tool replacement due to the material abrasive properties.
Where to Buy
Countertop fabricators and contractors can source complete prep sink fixture sets from numerous professional plumbing supply channels. Major wholesale distributors including Ferguson Enterprises, F.W. Webb, Hajoca, and Winsupply maintain extensive inventories of prep sink faucets, soap dispensers, and air switch systems suitable for this hole pattern. Popular prep sink faucet options include Delta Trinsic and Compel series, Moen Align and Arbor collections, Kohler Simplice and Malleco models, Kraus Oletto and Sellette designs, and Blanco Alta and Sonoma lines. Many manufacturers offer coordinated accessory packages that include matching soap dispensers in identical finishes, ensuring cohesive aesthetics. For soap dispensers, consider built-for-purpose models from KitchenAid, InSinkErator, Delta, and Kraus that offer larger capacity reservoirs requiring less frequent refilling. Air switch systems from InSinkErator, Waste King, and KitchenAid provide reliable garbage disposal control with finish options to match popular faucet collections. When specifying fixtures for client projects, recommend purchasing all three components from the same manufacturer finish family when possible to ensure perfect color and texture matching. For premium installations, luxury brands like California Faucets, Waterstone, and Newport Brass offer fully customizable prep faucet packages with coordinating accessories in extensive finish selections including living finishes that develop natural patina over time.
