- Install Faucet: Install your chosen faucet (sold separately) onto the countertop or wall, following its specific installation instructions. Connect the water supply lines.
- Test for Leaks: Turn on the water supply and check all connections for leaks. Run water into the sink and observe the drain and overflow for any signs of leakage.
