Tub Stopper — Five Types and How to Remove or Replace

A tub stopper is the plug or closure device in a bathtub drain that seals the opening so the tub can hold water.

What It Is

The tub stopper creates a watertight seal across the tub drain opening when engaged. When released, it allows water to flow freely out of the tub. Depending on the design, the stopper sits directly in the drain opening or is an internal plunger that rises and falls inside the drain pipe below the drain body.

A functioning stopper is essential for filling the tub. Worn or misadjusted stoppers are one of the most common bathtub complaints — either the tub will not hold water or the stopper will not open fully and drains slowly.

Types

Five stopper types are common in residential tubs. Lift-and-turn stoppers have a knob on the cap that you twist and press to lock closed. Push-and-pull stoppers open and close by pushing or pulling the cap directly. Toe-touch stoppers open and close with a press of the toe — a spring mechanism holds the position. Trip-lever stoppers use a lever on the overflow plate to move a plunger inside the overflow tube that blocks or unblocks the drain pipe. Pop-up stoppers are actuated by the trip-lever but sit in the drain opening rather than inside the pipe.

Where It Is Used

The stopper is located at the tub drain in every bathtub. Floor-mount types (lift-and-turn, push-and-pull, toe-touch, pop-up) are visible at the drain opening. Trip-lever plungers are concealed inside the drain pipe and are not visible.

How to Identify One

Look at the drain opening at the tub floor. A visible cap, knob, or dome indicates a floor-mount stopper type. If the drain opening looks like an open strainer with a crossbar and no movable cap, the tub likely uses a trip-lever plunger system controlled from the overflow plate.

Replacement

Most floor-mount stoppers unscrew or unclip from the drain body without tools or with just a screwdriver. Bring the old stopper to a plumbing supply store to match the thread size and style. Trip-lever linkages are adjusted by lengthening or shortening the threaded rod; a worn or corroded linkage assembly can be replaced as a kit.

Tub Stopper — FAQ

Why won't my bathtub hold water with the stopper closed?

For floor-mount stoppers, the rubber seal on the stopper cap has likely worn flat and no longer creates a tight seal against the drain opening. Replacing the stopper usually costs less than ten dollars and resolves the problem. For trip-lever systems, the linkage rod may need to be lengthened so the plunger drops fully into the drain pipe.

How do I remove a lift-and-turn tub stopper?

In the open position, look for a small setscrew on the side of the knob. Loosen it with a small hex key and lift the stopper out. If there is no setscrew, twist the stopper counterclockwise while pulling up — the cap threads onto a post in the drain body and will unscrew with enough turns.

How do I remove a toe-touch tub stopper?

Open the stopper by pressing it, then grasp the cap and turn it counterclockwise. The body of the stopper threads onto a post in the drain body. After the cap is off, the post can be unscrewed with a flathead screwdriver. Bring both pieces when shopping for a replacement.

What is the difference between a trip-lever stopper and a pop-up stopper?

Both use a lever on the overflow plate, but the mechanism differs. A trip-lever stopper has a brass plunger that drops inside the drain pipe below the tub floor. A pop-up stopper has a linkage that raises and lowers a visible stopper cap in the drain opening at the tub floor. Pop-ups are easier to clean because the stopper is accessible from above.

Can I replace my trip-lever stopper with a toe-touch stopper?

Yes. Conversion kits are available that replace the trip-lever linkage with a toe-touch or push-and-pull stopper sitting in the drain opening. The overflow plate and tube remain in place; the internal linkage is simply removed. This is a straightforward DIY upgrade for most homeowners.
