            Turn off the water supply valves under the sink and verify no water flows from the faucet. Place a bucket under the P-trap and disconnect the drain and water supply lines using a wrench. Remove the old sink by loosening mounting clips or cutting caulk around the edges. Clean the countertop or vanity surface thoroughly to remove old caulk and debris. Install the faucet onto the new sink following the manufacturer's instructions. Attach the drain assembly to the sink using plumber's putty to seal the flange. Apply a bead of plumber's putty or silicone around the sink edge if required. Carefully lower the sink into the countertop or vanity opening. Align the sink properly and use mounting clips or brackets to secure it in place. Wrap Teflon tape around the threads of the faucet connections. Connect the water supply lines to the faucet and tighten with an adjustable wrench. Install the P-trap by connecting it to the drain tailpiece and wall pipe. Ensure all connections are snug but not over-tightened to avoid damage. Turn on the water supply valves and check for any leaks at all connections. Run water through the faucet and observe the drain for proper flow and leaks. Tighten any fittings slightly if minor leaks are detected. Apply a bead of silicone caulk around the sink edge where it meets the countertop. Smooth the caulk with a wet finger or caulk tool for a clean finish. Allow the caulk to cure as per the manufacturer's recommended time before use. Clean up tools and dispose of any old parts or debris properly.
