Installation Requirements

This sink is designed for two-piece installation with the compatible pedestal leg. Wall backing should be evaluated prior to installation to support wall-mount anchoring. The unit includes predrilled mounting holes for standard lavatory bolts. Use of silicone sealant is recommended between the lavatory and finished wall to prevent moisture intrusion. Plumbing rough-in should be aligned to fit within the pedestal column.

Installer Guidance: Confirm faucet compatibility with the 4-inch center pattern. Secure lavatory to wall using hardware that complies with local building codes. Ensure pedestal base supports vertical alignment of trap and tailpiece.
