Grab the Necessary Tools and Materials

If you do need to remove your tub drain, be sure to grab the necessary tools and materials for preparation. The tools and materials that you need include:

  • A bathtub drain wrench also called a drain key
  • A long screwdriver
  • Plumber pliers also called channel locks
  • Rubber gloves
  • Plumbers putty
  • A new tub drain

Remove Current Tub Drain

The first step to replace a tub drain is to remove the current drain by inserting the drain key into the drain. Each end of the drain key should be a different size to fit nearly any size of tub drain out there. You can insert the long screwdriver through the body of the drain key and use as a handle to try to loosen and remove your current drain.

Turn the drain key counterclockwise and if it is too stuck to budge, try using the channel locks instead of the screwdriver. Slow and steady pressure is the best. Try to avoid hitting it with a hammer or jerking it top forcefully as you can break the bottom of the drain.

There are times you will need an “access panel” available to get to the drain piping below. When removing the drain, watch for “tension” in the piping, as the piping could drastically move away from the tub drain opening, thus having a difficult time to locate drain ell to place new drain into the threads.

Clean the Drain Area

Clean the area around the drain, removing any old, stuck on plumbers putty, dirt and debris. This area must be clean to install the new tub drain.

Replace Tub Drain

Now it’s time to replace your tub drain by simply screwing the new drain in clockwise. Use consistent pressure until the drain is fully seated.
