How to Remove Bathroom Sink Drain?

Step 1: Gather Your Supplies for the Project

Before diving into the removal process, it’s crucial to gather all the necessary tools and materials. Here’s a list of items you’ll need:


  1. Adjustable pliers
  2. Pipe wrench
  3. Plumber’s putty knife
  4. Screwdriver (Phillips and flathead)
  5. Bucket
  6. Towels or rags


  1. Plumber’s tape (Teflon tape)
  2. Replacement sink drain assembly (if needed)

Step 1: Prepare Your Work Area

Start by clearing out the area under the sink and placing towels or rugs to catch any water that may spill during the process. Having a clean and organized workspace will make the task much easier.

Step 2: Turn Off the Water Supply

Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply. This step is essential to prevent any water from flowing when you disconnect the pipes.

Step 3: Remove the P-Trap

The P-trap is the U-shaped pipe located beneath the sink. Using your adjustable pliers or pipe wrench, loosen the slip nuts on both ends of the P-trap and remove it. Be prepared for some water to drain out, so keep your bucket handy.

Step 4: Disconnect the Tailpiece

The tailpiece is the pipe that connects the sink drain to the P-trap. Use your pliers or pipe wrench to disconnect it from the drain.

Step 5: Remove the Sink Stopper

To access the drain from the top, you’ll need to remove the sink stopper. Depending on the type of stopper you have, you may need to unscrew it or lift it out.

Step 6: Loosen the Locknut

Beneath the sink, you’ll find a locknut that secures the drain in place. Use your pliers or pipe wrench to loosen the locknut by turning it counterclockwise.

Step 7: Remove the Drain

Once the locknut is loose, you can simply lift the drain assembly out of the sink.

With the drain removed, take this opportunity to clean the area thoroughly. Remove any old plumber’s putty or debris from the sink opening. Inspect the drain for any damage or corrosion, and if necessary, replace it with a new drain assembly.

Step 9: Apply Plumber’s Tape

Before reinstalling the drain, wrap a few layers of plumber’s tape clockwise around the threads of the drain body. This will create a watertight seal when you reassemble the sink.

Step 10: Reassemble the Drain

Carefully lower the drain assembly back into the sink opening, ensuring that it is aligned correctly. Tighten the locknut beneath the sink to secure the drain in place.

Step 11: Reattach the Tailpiece

Connect the tailpiece back to the bottom of the sink drain and tighten it securely using your pliers or pipe wrench.

Step 12: Reattach the P-Trap

Slide the P-trap back into place, connecting it to both the tailpiece and the drain. Tighten the slip nuts on both ends to secure the P-trap.

Step 13: Turn On the Water Supply

Return to the shut-off valves and turn them counterclockwise to restore the water supply to the sink.
