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 in under five minutes, and the replacement part costs between $10 and $40. The real work is identifying which of the three common types you have — because each one comes out differently, and buying the wrong replacement wastes time and money.

Before you buy anything, you need to see what you're working with. Stoppers fall into three categories: the pop-up stopper (the kind you push down to close and push again to open), the lift-and-turn stopper (you twist it to close), or the push-down stopper (you press it once to close, once more to open). Each type has a different removal method, and the parts are not interchangeable.

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 stoppers unscrew directly from the drain — no hidden parts — and the replacement screws back in the same way.
  • Push-down stoppers pop straight up out of the drain once you remove a set screw or clip on the side.
  • Measure your drain opening before ordering a replacement, because stoppers come in standard sizes and an oversized one will not fit.
  • If the stopper spins freely but won't tighten, the threads inside the drain are stripped and you may need a plumber to rethread or replace the drain body.

Removing a Pop-Up Stopper

Pop-up stoppers are the most common type in older homes. The stopper itself sits in the drain, but it is connected by a rod that runs through the overflow hole on the side of the tub. To remove it, you first have to access that rod.

Locate the overflow plate — a small rectangular or round cover on the tub wall, usually near the top edge. Unscrew the two bolts holding it in place (usually Phillips head, sometimes slotted). Pull the plate straight out toward you. Behind it, you will see a metal rod attached to a spring and linkage. Pull that entire assembly straight out. The stopper in the drain will come up with it. Once the linkage is out, the stopper itself should lift free from the drain.

Before you install the new stopper, check the linkage. If the spring is rusted or the rod is bent, replace the whole assembly — it costs about the same as just the stopper and will work better. If the linkage looks fine, you can reuse it with a new stopper head.

Removing a Lift-and-Turn Stopper

Lift-and-turn stoppers are the simplest to replace because there are no hidden parts. The stopper screws directly into the drain opening, and you remove it by hand.

Grip the stopper firmly and turn it counterclockwise. It will unscrew from the drain body. Once it is loose enough, lift it straight up and out. If it is stuck, wrap a cloth around it for better grip, or explore a penetrating oil like WD-40 and wait 15 minutes before trying again. Do not use a wrench — you can crack the stopper or strip the threads inside the drain.

To install the new stopper, screw it clockwise into the drain by hand until it is snug. Do not overtighten. If it spins without tightening, the threads are damaged and you will need a plumber to fix the drain body itself.

Removing a Push-Down Stopper

Push-down stoppers (also called spring-loaded or toe-touch stoppers) sit in the drain and pop up when you press them a second time. They are held in place by a small set screw or clip on the side of the stopper body, just below the drain rim.

Look at the side of the stopper where it meets the drain. You will see a small screw or a metal clip. If it is a screw, use a Phillips or flathead screwdriver (whichever fits) to loosen it. If it is a clip, pry it gently upward with a flathead screwdriver. Once the screw or clip is removed, the stopper will lift straight out of the drain.

To install the new stopper, drop it into the drain opening, align the set screw or clip hole with the side of the drain, and tighten the screw or snap the clip back into place. The stopper should sit flush with the drain rim and move freely up and down.

Measuring and Buying the Right Replacement

Drain stoppers come in standard sizes, and the wrong size will either fall through the drain or sit too high and catch on the tub rim. Measure your drain opening before you shop.

Use a ruler or measuring tape to measure the diameter of the drain opening at the widest point. Most bathtub drains are either 1.5 inches or 1.625 inches. Write down the exact measurement and take a photo of your old stopper if you still have it. When you order online or go to a hardware store, tell them the size and the type (pop-up, lift-and-turn, or push-down). If you are unsure, bring the old stopper with you or ask the store to match it.

Troubleshooting Common Problems

If the new stopper does not hold water, the drain opening may be slightly larger than the stopper. Try a stopper one size up, or check that the rubber seal on the bottom of the stopper is clean and not cracked. A thin film of soap scum or mineral deposits can prevent a seal. Rinse the stopper and the drain rim with white vinegar and a soft brush, then dry both completely before reinstalling.

If the stopper will not stay down, the linkage (on pop-up models) may need adjustment. The rod that connects the overflow plate to the stopper can be bent slightly to increase tension. Loosen the set screw on the linkage rod, bend it slightly, and retighten. Test the stopper. If it still will not hold, the spring may be too weak and the entire linkage assembly should be replaced.

If the stopper spins but will not tighten (on lift-and-turn models), the threads inside the drain are stripped. This requires a plumber to rethread the drain body or replace it entirely. Do not force it — you will damage the drain further.

When to Call a Plumber

Most stopper replacements are a 10-minute job. Call a plumber if the drain body itself is cracked, if the threads are stripped and the stopper will not tighten, or if water is leaking from the overflow hole even after you install a new stopper. A plumber can also help if the linkage on a pop-up stopper is so corroded that it will not come out — they have tools to extract it without damaging the tub.

If you have replaced the stopper and water still drains slowly or not at all, the problem is not the stopper — it is a clog deeper in the drain line. A plumber or drain cleaning service can clear that, but it is a separate issue from stopper replacement.

Frequently Asked Questions

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

No. Pop-up stoppers require the linkage rod that runs through the overflow hole. A lift-and-turn stopper has no linkage and will not work in that drain. You must replace it with the same type, or hire a plumber to modify the drain body.

What if I lose the set screw from my push-down stopper?

The stopper will fall into the drain. You can fish it out with a wire hook or pliers, but you will need a replacement set screw. Hardware stores sell them individually for a few dollars. Bring the stopper with you so the staff can match the size and thread type.

How do I know if my drain stopper is broken or just stuck?

Try explore penetrating oil and waiting 15 minutes. If it still will not move, it is likely corroded or broken. Remove it as described above. If the rubber seal is cracked, the spring is rusted, or the body is cracked, replace it. If it looks intact, clean it thoroughly and reinstall it to see if it works.

Do I need to turn off the water before replacing a stopper?

No. The stopper sits in the drain, not in the water supply line. You do not need to shut off water or drain the tub. Just remove the old stopper and install the new one.
