What can possibly prepare you to face a bathtub without a plug? Nothing. You 𑁋and most of people will be insticntively positive that the plug is there to block your tub.
But sometimes, everything in your home goes missing at one point. Even a plug! That’s why, we, as one of the blocked drain specialists, will guide you to create a DIY tub stopper.
Let’s get started!
What Can You Use Instead of a Bathtub Stopper?

In a pinch, you can block a bathtub drain using everyday household items. Your three fastest options are a rubber flip-flop, a water-filled plastic bag, and a folded sponge or small towel. Each one requires zero tools and less than a minute to set up.
1. The Rubber Flip-Flop Trick. Grab a rubber flip-flop and press its flat sole firmly over the drain. The flexible rubber naturally conforms to the drain’s shape, creating a surprisingly snug seal. This works best with thinner, flat-soled sandals.
2. Plastic Bag + Water Combo. Fill a small zip-lock or grocery bag with water, seal it tight, then press it into the drain opening. The water weight pushes the bag outward, plugging the drain from the inside. It’s oddly effective and oddly satisfying!
3. A Sponge or Small Towel. Roll up a sponge or a small hand towel tightly and stuff it into the drain until it fits snugly. It won’t hold forever, but it buys you enough time for a decent soak.
5 Ways to Block Your Bathtub Drain Without a Plug
So, your plug’s gone and you’re not in the mood to run to the store. Fair enough. Here are some easy, slightly unexpected ways to keep that precious bathwater where it belongs—in the tub.
1. The Rubber Flip-Flop Trick

This one’s surprisingly brilliant. Got an old rubber flip-flop lying around? Cut out a piece that’s big enough to cover your drain. It’s flexible, waterproof, and already shaped for the job.
How to do it:
- Snip out a flat piece from the sole—make sure it’s wide enough to sit over the drain opening.
- Place it over the drain and step on it to seal.
- Add a bit of weight on top (a shampoo bottle does nicely) and start filling the tub.
It’s one of the best hacks for how to keep water in the bathtub without a stopper—cheap, fast, and weirdly satisfying. However, you need to ensure the drain is clear from any clogs.
Go grab the drain snake and clear out the drain quickly before blocking it with your new “plug”.
2. Plastic Bag + Water Combo

This one is easy, but you need to unblock the drain first to avoid more disaster as we’ve stated above.
Fill a sturdy plastic bag (like a freezer bag) with water and seal it. Pop it over the drain, and it’ll naturally press into the shape of the opening.
Bonus: it’s reusable and takes under a minute to set up.
3. The Tiptop Bottle Cap Hack

Don’t underestimate that big tip top bottle cap from your shampoo, lotion, or detergent bottle. If it’s wide enough to cover the drain and has a flat surface, it can double as a makeshift bath plug in a pinch.
How to use it:
- Rinse it well (unless you want your bath smelling like fabric softener).
- Flip it closed and press it firmly over the drain.
- Place something a little heavy on top to keep it sealed.
It opens, closes, and holds water back surprisingly well—just like magic, but with more bubbles.
4. Use a Sponge or Small Towel

This one’s for the desperate-but-determined. Grab a clean sponge or roll up a small towel tightly. Push it gently into the drain. It may not be a permanent fix, but it’ll give you enough soak time to forget your plug troubles.
Also, if you got gunk around the drain, try pouring boiling water down to help clear out any grime and make a better seal.
5. Grab an Inflated Balloon

Yes, really—a balloon! Blow up a small balloon just enough to fit snugly into the drain. The air pressure keeps it in place and stops water from slipping through.
Steps:
- Inflate the balloon slightly—don’t overdo it.
- Push it gently into the drain until it seals tightly.
- Fill your tub and relax (just don’t pop it by accident!).
Pro tip: If you’ve had to unclog a bathtub recently, double-check that your balloon sits well. A clean drain will help it seal better. However, if you need a professional help, let a plumber check your bathtub plumbing system thoroughly.

Which DIY Stopper Works Best for Your Drain Type?

Not all bathtub drains are built the same, so the hack that works perfectly for your neighbor might not work as well for you. Here’s a quick guide to help you match the right DIY fix to your specific drain type.
- Small Round Drain. This is the most common type, and a slightly inflated balloon or a water-filled plastic bag are your best friends here. Both mold themselves naturally into the opening, giving you a snug and reliable seal without much effort.
- Wide Flat Drain. Go for the rubber flip-flop trick or a bottle cap that’s wide enough to sit flat over the surface. The goal here is coverage, so anything with a broad, flat base will outperform something you have to stuff inside the drain.
- Drain Near the Tub Wall. Space is tight, so you’ll want something flexible and easy to maneuver. A small sponge or a tightly rolled towel works well since you can squeeze it into place without needing extra room to work with.
- Odd-Shaped Opening. The plastic bag filled with water is your most adaptable option here. Since it naturally conforms to whatever shape it’s pressed against, it handles irregular drain openings better than any of the other solutions on this list.
What Should You Avoid?

Before you start raiding your bathroom cabinet for anything that might fit over the drain, it’s worth knowing what not to use. Some materials can cause more trouble than a missing plug ever would!
- Sharp Objects. Sharp edges can scratch or damage your tub’s surface, and there’s also the obvious safety risk of reaching into the water and accidentally cutting yourself. It’s just not worth it.
- Breakable Plastic. Thin or brittle plastic items like old bottle lids, cracked containers, or cheap plastic wrap might seem like a quick fix, but they can snap under water pressure or the weight of your foot.
- Forcing Items Deep Into the Drain. Whatever you use, it should sit over or just at the entrance of the drain, not inside it. Pushing something too deep will get it lodged in your pipes. You may need professional help to fix this.
FAQ about Blocking a Bathtub Drain Without a Plug
How do you unscrew a bathtub drain plug?
Great question—and it depends on the type of plug you have. Most modern plugs either twist off or pop out with a little wiggle.
Here’s how to try it:
- For twist-style plugs: Grip the top and turn counterclockwise.
- For push-and-pull or lift-and-turn styles: Lift the plug and keep turning until it loosens.
Stuck? Wrap a cloth around it and use pliers for extra grip (gently!). If it doesn’t budge, don’t force it—you don’t want to damage the drain. A little WD-40 and patience usually does the trick.
How do you take a bath if you don’t have a drain plug?
No plug? No stress. You’ve got options! You can DIY a temporary plug with household items—like a sponge, a cut-up flip-flop, a small lid, or even an inflated balloon.
Just make sure the item seals the drain tightly and can handle a little water pressure.
Can you replace the bathtub plug?
Absolutely! You can find replacement plugs online or at any hardware store. Just make sure you get the right size and type for your tub.
There are universal plugs that fit most drains, or you can go with the exact match based on your old one.
Is a washcloth safe to use in a bathtub drain?
Yes, a washcloth is one of the safer DIY options you can use! Just make sure to roll or fold it tightly enough to cover the drain opening properly. The key thing to remember is to never push it too far down into the pipe since retrieving a lodged washcloth can get messy fast.
Why does my tub keep draining even when I cover the drain?
If water keeps sneaking out despite your makeshift stopper, the most likely culprit is an uneven or poor seal between your DIY plug and the drain surface. This usually happens when there’s built-up grime or debris around the drain rim that prevents a flush contact.
Try cleaning around the drain opening first, then reapplying your stopper. It also helps to add a little weight on top, like a shampoo bottle, to press the seal down more firmly.
