First, shut off the hot and cold water supply by turning the shut-off valves under the sink clockwise. Place a bucket underneath to catch drips. Use a basin wrench or adjustable wrench to disconnect the water supply lines from the old faucet. Unscrew the mounting nuts holding the old faucet in place. Once loose, lift the entire old faucet assembly out from the top of the sink and clean the area.

FAQs
How difficult is this bathroom sink and faucet installation for a beginner, and how much time should I set aside?
This project is categorized as 'beginner' difficulty, making it very approachable for DIYers. For a first-timer, plan to dedicate 4-6 hours from start to finish, including preparation and cleanup. Rushing can lead to mistakes, so allow extra time for unexpected issues.
What are the most critical safety steps I need to take before starting to remove the old sink and work on plumbing?
The absolute most critical step is to shut off the water supply to the sink, either at the shut-off valves under the sink or the main water supply to your house. Also, place a bucket and towels under the work area to catch any residual water, and consider wearing safety glasses when using tools or working with pipes.
Is a basin wrench, like the TEKTON WRN92004, truly necessary for this project, or can I use regular pliers?
While you might be able to manage with large channel-lock pliers in some cases, a basin wrench (e.g., TEKTON WRN92004) is highly recommended. It's specifically designed for reaching and loosening the difficult-to-access mounting nuts on faucets, especially in tight spaces, making the job significantly easier and faster.
What's the most common mistake beginners make when installing the drain assembly or sealing the sink, and how can I avoid it?
A common mistake is either not using enough plumber's putty (like Oatey 14 oz. Plumber's Putty) around the drain flange, or over-tightening plastic drain fittings, which can crack them. Ensure a generous, even ring of putty under the drain flange for a watertight seal, and hand-tighten plastic connections, then give a quarter-turn with pliers, being careful not to overtighten.
