This project is rated as beginner-friendly, but requires careful attention to detail. For someone new to DIY, expect it to take anywhere from 1 to 3 hours, including gathering your tools and cleaning up. Experienced DIYers might finish it in under an hour, but it's best to allow ample time to avoid rushing and potential mistakes.

If your shut-off valves are problematic or missing, you'll need to turn off the main water supply to your entire house before proceeding. This is a critical safety step to prevent flooding. If the valves are seized or actively leaking, it's a good opportunity to replace them or call a plumber before installing the new faucet.

While the adjustable and basin wrenches are crucial, also have a bucket or small container, old towels or rags, and a flashlight handy. A utility knife or scraper can help remove old caulk or putty, and a small wire brush might be useful for cleaning the sink surface. Don't forget plumber's putty, as specified.

Most leaks stem from improperly tightened supply line connections or an insufficient seal at the faucet base. Ensure all supply lines are hand-tightened first, then given an additional quarter to half turn with your wrench. Apply a consistent, generous bead of plumber's putty around the base of the new faucet to create a watertight seal and prevent water from seeping under the fixture.
