What You Need to Know Before You Start

A bathtub drain stopper that won't hold water or won't pop up is usually fixable without calling a plumber. Most stoppers come out by hand or with one straightforward tool, and replacement parts cost between $10 and $40. The whole job takes about 30 minutes, and you only need a screwdriver and possibly a pair of pliers.

Before you buy a replacement, you need to know which of three types you have: a pop-up stopper (the kind you push down to close), a lift-and-turn stopper (twist to open and close), or a push-pull stopper (push down to close, pull up to open). Each one comes out differently, and each one has its own replacement parts. The good news is that once you remove the old one, you'll see exactly what you're working with.

Key Takeaways

  • Pop-up stoppers require you to remove the overflow plate on the tub wall and pull out the linkage rod that connects to the stopper underneath.
  • Lift-and-turn and push-pull stoppers usually unscrew from the drain opening itself, with no hidden parts to remove.
  • Before buying a replacement, measure your drain opening and note whether your old stopper had a threaded base or a friction fit.
  • The entire removal and installation process takes 15 to 30 minutes and requires only a screwdriver and possibly pliers.
  • If water leaks around the new stopper after installation, the rubber seal may need adjustment or the stopper may need to sit lower in the drain.

How to Remove a Pop-Up Stopper

Pop-up stoppers are the most common type in older and mid-range bathtubs. To remove one, start by unscrewing the overflow plate—the small rectangular cover on the tub wall near the top edge. This plate is usually held by one or two screws. Once the plate is off, you'll see a metal rod connected to the stopper mechanism underneath the tub.

Pull this rod straight out through the overflow opening. It may take some wiggling, but it should come free. Once the rod is out, reach down into the drain opening and lift out the stopper itself. You may need to rotate it slightly to clear the drain opening. If the stopper is stuck, spray a little white vinegar or penetrating oil around the base and wait five minutes before trying again.

How to Remove a Lift-and-Turn or Push-Pull Stopper

These stoppers are simpler because they have no hidden linkage. Look at the stopper itself—you'll see a small slot or notch on the side near the base. Insert a flat-head screwdriver into this slot and turn counterclockwise. The entire stopper will unscrew from the drain opening. If it's stuck, explore penetrating oil and wait a few minutes, then try again with the screwdriver.

If your stopper has no visible slot, it may be a friction-fit type that straightforward pulls straight up. Grip it firmly with your hand or a pair of pliers and pull straight up with steady pressure. Do not twist or rock it side to side, as this can damage the rubber seal inside the drain.

Installing Your New Stopper

Before you install the new stopper, clean the drain opening with a damp cloth to remove hair and debris. This helps the new seal sit properly and prevents leaks. Wipe the threads or the inside of the drain opening until no visible buildup remains.

For a threaded stopper (lift-and-turn or push-pull), insert the stopper into the drain opening and turn clockwise by hand until it's snug. Do not over-tighten—you only need it tight enough that it won't spin when you operate it. If your stopper came with a rubber washer or O-ring, make sure it's seated in the groove before you screw the stopper down.

For a pop-up stopper, the process is reversed. First, insert the stopper into the drain opening and make sure it sits at the right height—it should be flush with the tub floor when closed, or slightly recessed. Then feed the linkage rod back through the overflow opening and screw the overflow plate back on. The rod should move freely up and down without binding.

Testing and Adjusting for Leaks

Fill the tub with a few inches of water and close the stopper. Watch for water leaking around the base. If water seeps out, the seal is not sitting properly. For a threaded stopper, try turning it a quarter-turn tighter. For a pop-up stopper, the linkage rod may need adjustment—loosen the overflow plate slightly and shift the rod up or down, then retighten.

If tightening does not stop the leak, the rubber seal inside the stopper may be worn or the drain opening may have debris. Remove the stopper again, clean the drain opening thoroughly with a cloth, and reinstall. If the leak continues, the drain opening itself may be damaged, and you may need a plumber to assess whether the drain needs repair.

Common Mistakes to Avoid

Do not force a stuck stopper. If it won't budge after you've applied penetrating oil and waited, spray again and wait longer. Forcing it can crack the stopper or damage the drain threads. Most stuck stoppers come free within 24 hours of soaking with oil.

Do not over-tighten a threaded stopper. Hand-tight plus a quarter-turn with a screwdriver is usually enough. Over-tightening can crack the stopper or strip the threads in the drain, making future removal difficult or impossible. Do not mix up your old stopper parts when you remove them. If you have a pop-up stopper, keep the linkage rod and overflow plate together so you can reference them when installing the new one. Take a photo of the old assembly before you disassemble it if you're unsure how it all fits together.

When to Call a Plumber

If the drain opening is cracked, if the threads are stripped, or if water leaks from the drain itself rather than around the stopper, you have a problem beyond stopper replacement. A plumber can assess whether the drain needs repair or replacement.

If your tub is very old and the stopper won't come out even after soaking with penetrating oil for 24 hours, a plumber can remove it without damaging the drain. Attempting to force an extremely stuck stopper yourself risks breaking the drain fitting or the tub itself, which is far more expensive to repair than hiring help from the start.

Frequently Asked Questions

How do I know which type of stopper I have?

Pop-up stoppers pop up and down with a push. Lift-and-turn stoppers twist open and closed. Push-pull stoppers push down to close and pull up to open. Look at how you currently operate your stopper—that tells you the type. If you're not sure, take a photo and bring it to a hardware store; staff can identify it for you.

Can I replace a pop-up stopper with a lift-and-turn stopper?

Not without additional work. Pop-up stoppers require the overflow linkage, which lift-and-turn stoppers do not use. You would need to cap off the overflow opening, which requires a plumber. It's simpler to replace a pop-up stopper with another pop-up stopper of the same size.

What size stopper do I need?

Measure the diameter of your drain opening with a ruler or tape measure. Most bathtub drains are 1.5 inches or 1.625 inches. Bring this measurement to the hardware store, or order online by drain size. The package will tell you which tub types it fits.

Why is water leaking around my new stopper?

The rubber seal may not be seated properly, or the stopper may be sitting too high in the drain. Remove the stopper, clean the drain opening with a cloth, and reinstall it. Make sure it sits flush with the tub floor. If the leak continues, the drain opening may have a chip or crack that prevents a watertight seal.

How often do I need to replace a drain stopper?

A stopper typically lasts five to ten years depending on use and water quality. If yours stops holding water or won't stay in the up position, replacement is the easiest fix. Rubber seals wear out over time and cannot be repaired—only replaced.
