Drill the drain hole and faucet hole on the countertop, according to the shape and size of vessel sink.

Carefully place the sink upside down on the counter with a towel or other soft cloth beneath to prevent damage.

Apply a continuous bead of silicone to the base of the vessel sink where it will rest on the counter.

Turn the sink right-side up and position it back over the drain hole.

Remove any excess silicone with a damp cloth. Let the adhesive dry for 24 hours.

Connect the drain to the sink and connect water supply connections according to the manufacturer's instructions.

Ensure that there are no leaks by running water into the sink.
