4.3 Installation Steps
The KES BVS121 vessel sink is designed for top-mount installation. It does not have a faucet hole or an overflow. It is compatible with wall-mount or counter-mount faucets.
- Prepare the Countertop: Ensure your countertop has a suitable opening for the drain. The recommended opening hole size is 3 to 4 inches in diameter. The standard sink hole diameter for the drain is 1-11/16 inches.
- Position the Sink: Place the vessel sink on the countertop to determine its final position. Mark the center of the drain opening on the countertop.
- Install the Faucet: Install your chosen wall-mount or counter-mount faucet according to its manufacturer's instructions. Ensure the faucet spout extends sufficiently over the sink bowl to prevent splashing.
- Install the Drain: Install the drain assembly into the sink's drain opening according to the drain manufacturer's instructions.
- Secure the Sink: Apply a bead of silicone sealant around the bottom edge of the sink where it meets the countertop. Carefully place the sink onto the countertop, aligning the drain with the countertop opening. Press down firmly to create a seal.
- Connect Plumbing: Connect the drain assembly to your plumbing system. Connect the faucet water supply lines.
- Test for Leaks: Turn on the water supply and check all connections for leaks. Allow the silicone sealant to cure completely before heavy use.
