How to Install a Bathroom Sink and Faucet from Start to Finish · Step 1 of 5
In this video
Before removing the old sink, shut off the water supply by turning the handles on the angle stop valves clockwise until they stop. Disconnect the hot and cold water supply lines from the valves using channel-lock pliers. Disconnect the P-trap from the wall drain and the sink tailpiece. Carefully cut any old caulk between the sink and wall with a utility knife. Lift the sink basin off the pedestal, then remove the pedestal itself.
Goal: Bathroom Sink Removal
- Have a bucket and rags ready, as there will be water in the P-trap and supply lines even after the main supply is shut off.
Used in this video
- Channel-lock Pliers — Loosening the large nuts on the P-trap and the nuts connecting the water supply lines.
- Utility Knife — Cutting the old caulk seal between the sink basin and the wall to free it.
- Bucket — Placing under the P-trap to catch water when it's disconnected.

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.
