How to Replace a Two-Handle Bathroom Faucet · Step 5 of 10
In this video
Place a bowl or bucket under the sink to catch any residual water from the P-trap. Use channel lock pliers to loosen the slip nuts connecting the P-trap and tailpiece to the sink drain and wall drain. Once loosened, these can usually be unscrewed by hand. Remove the P-trap and drain pipes. Next, unscrew the large locknut holding the existing sink strainer in place from underneath the sink. Once the locknut is removed, push the old strainer up and out of the sink hole. Clean any old plumber's putty or residue from around the sink hole.
Goal: Disassemble and remove the old sink drain and P-trap assembly.
- The water inside the P-trap will likely have a foul odor. Be prepared.
- Have paper towels ready to plug the sink drain temporarily and for cleanup.

FAQs
How long should a beginner expect to spend replacing a two-handle bathroom faucet and drain?
For a beginner, this project typically takes 2-4 hours, assuming no major complications like seized nuts. The difficulty is rated as 'beginner' because it involves straightforward steps, but patience is key, especially when working in tight under-sink spaces.
Are there any essential tools I might not already have that are crucial for this faucet replacement?
Yes, a basin wrench (like the Husky 1-1/2 in. Quick-Release Telescoping Basin Wrench) is invaluable for reaching and loosening nuts in tight spaces under the sink. You'll also want a quality adjustable wrench, tongue and groove pliers (Channellock 442), and a reliable flashlight (Panther Vision FLATEYE F-310) for visibility.
What are the critical preparation steps and safety precautions before I start disconnecting anything?
Always begin by shutting off both the hot and cold water supply valves under the sink, then turn on the old faucet to relieve pressure and drain residual water. Have a bucket (Unger 6 Gal. Heavy-Duty Plastic Bucket) and a rag (Better Trends Hugo Collection Bath Rug) ready to catch any spills and protect your cabinetry.
What are the most common reasons for leaks after installing a new faucet or drain, and how can I prevent them?
Leaks often occur from loose supply line connections or improper sealing of the drain assembly. Ensure all connections are hand-tightened, then given an additional quarter to half turn with a wrench. For the drain, properly apply plumber's putty (Oatey 14 oz. Plumber's Putty) around the flange before seating it.
