2. Installation Instructions
This Karran Valera vessel sink is designed for above-counter installation into various countertop materials. Professional installation is recommended to ensure proper sealing and functionality.
2.1. Pre-Installation Checklist
- Verify all components are present and undamaged.
- Ensure the countertop opening is correctly sized for a standard 1-3/4" drain.
- Confirm adequate space for the sink dimensions: 18-3/4" (length) x 14-1/2" (width) x 5-1/8" (overall height).
- Gather necessary tools: sealant, wrench, measuring tape, level.
2.2. Installation Steps
- Position the Sink: Carefully place the vessel sink on the countertop in the desired location, ensuring it is centered over the drain opening.
- Mark Drain Hole: Mark the exact position for the drain hole on the countertop if not already present. The sink requires a standard 1-3/4" drain opening.
- Apply Sealant: Apply a continuous bead of silicone sealant around the bottom edge of the sink where it will contact the countertop.
- Secure the Sink: Gently set the sink onto the sealant, aligning it with the drain opening. Apply even pressure to ensure a good seal.
- Install Drain Assembly: Install the drain assembly (not included) according to the manufacturer's instructions, ensuring a watertight seal.
- Connect Plumbing: Connect the P-trap and water supply lines to the faucet (if applicable) and drain.
- Cure Sealant: Allow the sealant to cure completely as per the sealant manufacturer's recommendations before using the sink.
- Test for Leaks: Once cured, fill the sink with water and check for any leaks around the drain and plumbing connections.

- Adjust water temperature and flow as desired using your faucet controls.
- After use, turn off the faucet completely to prevent water waste.
