The fabricator needs the required hole diameter and center spacing for the exact faucet and accessories. Soap dispensers, filtered-water faucets, air switches, and side sprays require additional holes. The faucet must clear the backsplash, window sill, sink ledge, and cabinet framing below. Changing faucet configuration after fabrication may require visible hole covers or professional modification.
Key considerations
- installation accuracy
- crack resistance
- water control
- custom hole spacing
- accessory openings
- fixture coordination
