Why can’t you flush paper towels down the toilet?

The 2020 pandemic changed many things, including the way people shopped for everyday essentials. One unexpected problem was the shortage of toilet paper in many stores. It might sound funny now, but finding a single roll was difficult in some places.

As a result, people started looking for alternatives. Some turned to paper towels because they were easy to find and seemed similar to toilet paper. But can you flush paper towels down the toilet?

The simple answer is no. Paper towels are designed to stay strong when wet, while toilet paper is made to break apart quickly in water. Flushing paper towels can clog your toilet, block drainpipes, and create expensive plumbing problems.

Let’s look at what happens when you flush paper towels, why they cause problems, and what you should do if you’ve already flushed one.

Can You Flush Paper Towels Down the Toilet?

No, you should never flush paper towels down the toilet. Even though they’re made from paper, they don’t behave like toilet tissue when they come into contact with water.

Paper towels are made to absorb spills without falling apart. That’s exactly what makes them useful in the kitchen but dangerous for your plumbing.

When you flush a paper towel, it may pass through the toilet bowl and disappear from sight. However, that doesn’t mean it has safely passed through the entire drainage system.

The towel can remain intact, become trapped in a pipe, or collect other waste. Over time, this can create a blockage that prevents water from draining normally.

According to the U.S. Environmental Protection Agency (EPA), only toilet paper should be flushed along with human waste. Items such as paper towels and wipes belong in the trash.

What Happens If You Flush Paper Towels Down the Toilet?

When you flush a paper towel, several things can happen depending on the size of the towel, your plumbing system, and whether there’s already a partial blockage.

First, the paper towel absorbs water but doesn’t break apart easily. It stays relatively strong as it moves through the toilet trap and drainage pipes.

If the towel gets caught at a bend, rough pipe joint, or another obstruction, it can trap toilet paper and other waste. Eventually, water may struggle to pass through the pipe.

Here are the most common problems caused by flushing paper towels:

• Clogged toilet: Paper towels can get stuck inside the toilet trap and restrict water flow.
• Blocked drainpipes: Towels may accumulate farther down the plumbing system.
• Slow drainage: Water may drain slowly as the blockage becomes larger.
• Sewage backup: A serious blockage can cause wastewater to return through the toilet or another fixture.
• Septic system problems: Paper towels can contribute to blocked pipes or interfere with septic system components.

One accidentally flushed paper towel won’t always cause an immediate clog. But that doesn’t make it safe to flush another one.

If your toilet is already having drainage problems, read our guide on how to fix a clogged toilet before attempting to clear the blockage.

How Long Do Paper Towels Take to Dissolve in Water?

Paper towels don’t dissolve in water the way sugar or salt does. They may gradually weaken and break into smaller pieces, but they are not designed to disperse quickly like toilet paper.

There is no reliable, universal answer such as five days or ten days. The breakdown time depends on the product’s thickness, fiber structure, wet-strength additives, and conditions in the water.

Here’s how common bathroom and household materials behave when wet:

Material	Behavior in Water	Safe to Flush?
Toilet paper	Designed to break apart relatively quickly	Yes, in reasonable amounts
Paper towels	Absorb water but remain relatively strong	No
Facial tissues	Generally resist breaking apart more than toilet paper	No
Baby wipes	Often remain intact and may contain synthetic fibers	No
Sponges	Hold their shape and do not disperse like toilet paper	No

The important point is that biodegradable doesn’t necessarily mean flushable. A material might eventually break down but still cause a blockage long before that happens.

What Are Paper Towels Made Of?

Paper towels, sometimes called kitchen rolls or kitchen paper, are disposable sheets used for wiping surfaces, drying hands, and cleaning spills.

Most are made primarily from cellulose fibers derived from wood pulp, recycled paper, or a combination of materials.

The fibers are processed to create a sheet that absorbs liquid while maintaining enough strength for cleaning.

Some manufacturers also use wet-strength additives to help the paper resist tearing when soaked.

This makes paper towels especially useful for:

• Cleaning kitchen counters and tables.
• Absorbing spilled water or other liquids.
• Drying hands and household surfaces.
• Wiping up small messes.

However, the same wet strength that makes these towels useful also makes them unsuitable for flushing.

What’s the Difference Between Toilet Paper and Paper Towels?

Toilet paper and paper towels may look similar, but they’re manufactured for different purposes.

Toilet paper is designed to lose strength and break apart in moving water. Paper towels are designed to absorb water while staying together.

1. Strength When Wet

Paper towels remain stronger when wet because they need to withstand wiping and scrubbing. Toilet paper loses much of its strength when soaked, helping it move through the drainage system.

2. Absorbency

Both products absorb moisture, but paper towels are generally designed to absorb and hold larger amounts of liquid during cleaning.

3. Breakdown in Water

This is the biggest difference. Toilet paper is manufactured to disperse under normal flushing and wastewater conditions.

Paper towels can remain in larger pieces, increasing the risk of clogs.

4. Intended Use

Toilet paper is intended for personal hygiene and toilet disposal. Paper towels are intended for cleaning and should be discarded in the trash after use.

Can You Use Kitchen Paper Towels Instead of Toilet Paper?

Yes, you can use paper towels for personal cleaning in an emergency, but you must not flush them.

If you’ve run out of toilet paper, a soft, unscented paper towel can serve as a temporary substitute. However, kitchen towels are often rougher than toilet tissue, so they may irritate sensitive skin.

Use them gently, and place the used towels in a lined, covered bathroom trash bin.

Wash your hands thoroughly afterward and empty the bin regularly.

For everyday use, regular toilet paper or a bidet is usually a more practical choice.

I Accidentally Flushed a Paper Towel Down the Toilet. What Should I Do?

If you accidentally flushed a paper towel, don’t panic. A single towel may pass through without an obvious problem, although there’s no guarantee.

The important thing is to avoid making a possible blockage worse.

Step 1: Don’t Keep Flushing

If the toilet is draining slowly or the bowl’s water level is rising, stop flushing immediately.

Repeated flushing can cause water to overflow onto your bathroom floor.

Step 2: Check for Signs of a Clog

Watch for slow drainage, gurgling sounds, rising water, or wastewater backing up.

If the toilet drains normally, there’s no need to assume a blockage has occurred. However, keep an eye on it during normal use.

Step 3: Try a Toilet Plunger

If the toilet becomes clogged, use a flange-style toilet plunger.

Place the rubber flange over the drain opening, create a good seal, and use steady plunging movements.

If the blockage clears and the water drains normally, the toilet may be usable again.

Step 4: Use a Toilet Auger If Necessary

A toilet auger can sometimes reach a blockage that a plunger cannot clear.

However, avoid forcing the auger through resistance because you could damage the toilet or push the material farther into the plumbing.

Our step-by-step guide explains how to use a toilet auger safely.

Step 5: Call a Plumber for Persistent Problems

If plunging and careful auger use don’t work, or multiple fixtures start backing up, contact a plumber.

The blockage might be deeper inside the drainage system.

Important: Don’t pour harsh chemical drain cleaners or boiling water into the toilet to dissolve paper towels. These methods are unreliable for paper-towel blockages and may damage plumbing or create safety hazards.

Can Paper Towels Clog a Septic Tank?

Yes. Flushing paper towels can create problems for homes with septic systems as well as homes connected to municipal sewers.

In a septic system, wastewater moves from your house into a tank where solids settle and wastewater undergoes treatment.

Paper towels don’t break apart as readily as toilet paper. They can contribute to blockages in the inlet plumbing or interfere with septic system components.

Repeated flushing increases the amount of unwanted material entering the system.

If you notice persistent sewage odors or drainage problems, our article on septic tank smells and their causes may help you understand what to check.

What Can You Use Instead of Toilet Paper?

If toilet paper isn’t available, you still have several alternatives. However, most should never be flushed.

1. Bidet

A bidet is one of the most practical alternatives to toilet paper.

It uses water to clean after using the toilet, reducing the amount of toilet paper you need.

Some bidet seats include adjustable water pressure, warm water, and air-drying features.

If you’re considering this option, our bidet toilet seat buying guide explains the available features and models.

2. Baby Wipes

Baby wipes can be used for personal cleaning, but they must go into the trash afterward.

Even wipes marketed as flushable may not break apart quickly enough to prevent plumbing problems.

3. Reusable Cloth

A clean, soft cloth can be used as a temporary alternative.

However, reusable cloth requires proper handling, separate storage, and thorough washing to maintain hygiene.

Never flush cloth into the toilet.

4. Water and a Handheld Sprayer

A handheld bidet sprayer or a dedicated water-cleaning container can help you clean yourself without relying entirely on toilet paper.

Use clean water and maintain the equipment properly.

Whichever option you choose, avoid putting paper towels, wipes, sponges, or cloth into the toilet.

How to Prevent Paper Towel Clogs

Preventing a paper-towel blockage is much easier than clearing one.

• Keep a covered trash bin in the bathroom: Make it easy to dispose of wipes and paper towels properly.
• Use toilet paper for flushing: Avoid substituting kitchen rolls or facial tissues.
• Teach family members what not to flush: Children and guests may not know the difference.
• Consider a bidet: It can reduce dependence on disposable paper products.
• Address slow drainage early: A developing blockage is easier to handle before wastewater backs up.

These simple habits can reduce the risk of expensive plumbing repairs.

Frequently Asked Questions

1. Will one paper towel clog a toilet?

Not necessarily. One paper towel may pass through without causing an immediate blockage. However, it can get trapped in the toilet or drainpipe, so flushing even one is risky.

2. Can you flush paper towels if you tear them into small pieces?

No. Smaller pieces may still remain intact, collect in pipes, or combine with other waste. Tearing paper towels doesn’t make them safe to flush.

3. Do paper towels eventually dissolve in a sewer pipe?

Paper towels may gradually weaken or break down, but there is no reliable timeframe. They can cause a blockage long before substantial breakdown occurs.

4. Can you flush Bounty paper towels?

No. Bounty and other household paper towels are designed for absorbency and wet strength, not for disposal through a toilet.

5. Can paper towels damage a septic system?

Yes. They can contribute to blocked septic plumbing and interfere with normal wastewater handling. Dispose of paper towels in the trash instead.

6. What’s the safest alternative when you run out of toilet paper?

A bidet or handheld water sprayer is a practical option. You can also use soft paper towels temporarily, but dispose of them in a covered trash bin rather than flushing them.

Final Thoughts

So, can you flush paper towels down the toilet? No, and it’s not worth taking the risk.

Paper towels are stronger and more absorbent than toilet paper. While these qualities make them useful for cleaning, they also mean paper towels can remain intact inside drainage pipes and cause clogs.

If you accidentally flush one, watch for drainage problems and avoid repeated flushing if the toilet starts backing up. A plunger or toilet auger may help with a minor blockage, but stubborn clogs may require a plumber.

When toilet paper isn’t available, use a bidet or another suitable alternative and dispose of non-flushable materials in the trash.

The easiest rule to remember is simple: flush human waste and toilet paper only. Everything else belongs in the trash.
