Free Printable Do Not Flush Signs | Official PDFs – A free printable do not flush sign is one of the simplest ways to stop costly toilet clogs. In U.S. homes, apartments, offices, schools, and vacation rentals, people still flush wipes, paper towels, and hygiene products that do not break down like toilet paper.
This page explains what belongs in the toilet, what does not, and where to download legitimate free signs and official posters you can print on standard U.S. Letter paper (8.5″ × 11″).
Why “Do Not Flush” Signs Matter?
U.S. wastewater utilities and the EPA have a simple rule: flush toilet paper, not wipes or trash.
Wipes, even many labeled “flushable,” are made to stay strong when wet. They can wrap around pumps, clog pipes, and mix with fats and grease to form “fatbergs.” That can mean a backup in your bathroom, a sewer overflow, or a higher bill for the whole community.
A sign works best when you also put a lidded trash can next to the toilet. The sign tells people what not to flush. The bin gives them a place to put it.
What You Can Flush?
Most U.S. sewer and septic operators use some version of the “3 Ps”:
- Pee
- Poop
- Toilet paper
New York City’s Department of Environmental Protection adds a fourth P — puke — and still tells residents to trash everything else, including wipes that say they are flushable.
If you are on a septic system, be even stricter. Wipes, paper towels, and feminine products can overload a tank and drain field. A small bathroom sign plus a trash can is cheap insurance compared with a pump-out or a plumber.
What Never Belongs in the Toilet?
Use this list on a printable restroom sign or post it near the stall:
- Wet wipes, baby wipes, flushable wipes, makeup wipes, and disinfecting wipes
- Paper towels, tissues, and napkins
- Feminine hygiene products and applicators
- Diapers and adult incontinence products
- Cotton balls, pads, and swabs
- Dental floss and teeth-whitening strips
- Hair, condoms, bandages, and cat litter
- Medicines (use a take-back program, not the toilet)
- Fats, oils, and grease (those go in the trash, not the drain)
Look for the official Do Not Flush symbol on wipe packages. If you see it, the product belongs in the trash. When you are not sure, throw it out.

How to Print and Display the Sign?
- Download a PDF and open it in a current PDF reader.
- Print on U.S. Letter paper (8.5″ × 11″) at actual size. Do not “fit to page” if that shrinks the type.
- Use card stock if you can. Laminate the sign or slip it into a cheap document sleeve so humidity and cleaners do not ruin it.
- Post it where people look before they flush: on the tank, on the wall above the toilet, or on the inside of the stall door at eye level.
- Put a second copy near wipe packs, changing tables, or paper-towel dispensers.
- Add a small covered trash can with a liner. A sign without a bin is easy to ignore.
For public restrooms, offices, and Airbnbs, English-only is not always enough. If you serve Spanish-speaking guests, add a short second line: No arroje toallitas ni productos higiénicos al inodoro.
Clear Wording That Works
Short beats cute. People read bathroom signs in two seconds.
Strong default text
DO NOT FLUSH
Wipes, paper towels, or hygiene products
Only toilet paper
Put everything else in the trash
Septic or rental version
Sensitive plumbing / septic system
Flush only toilet paper
No wipes — even if the package says “flushable”
Workplace version
Wipes clog pipes
Trash only — do not flush
Avoid tiny script and busy photos. High contrast (dark text on a light background, or white text on red or black) is easier to read from a stall.
Free Sign vs. Plastic Store Sign
A free printable do not flush sign is enough for most homes, guest baths, and short-term rentals. Laminate it and you can wipe it clean.
Buy a plastic or acrylic sign if the restroom is public, wet all day, or cleaned with harsh chemicals. The message can stay the same. You do not need to pay for a digital download if a city, state agency, or utility already offers the file for free.
Frequently Asked Questions
Are these do not flush signs really free?
The five resources linked above are free to download and print. None of those pages require you to buy a listing. Always print from the official or publisher page so you get the current file.
Can I flush wipes that say “flushable” or “septic safe”?
Most U.S. utilities still say no. “Flushable” often means the wipe leaves the bowl, not that it breaks down in your pipes or at the treatment plant. EPA and city sewer agencies tell people to trash wipes.
Where should I put the sign in an Airbnb or guest bathroom?
Place one sign on or just above the toilet and keep a small trash can with a lid and liners next to it. Mention the rule in the house manual once. Repeating it on five walls feels like a lecture; one clear sign is enough.
Do I need a different sign for a septic tank?
The list of banned items is the same. You can add “septic system” so guests understand why the rule is strict.
Is there an official Do Not Flush logo?
Yes. Industry and several state labeling laws use a standard Do Not Flush symbol on non-flushable wipe packages. You can print that symbol for restroom education from the Flush Smart professionals page linked above.
Quick Checklist
- Print a letter-size do not flush sign today.
- Laminate it or put it in a sleeve.
- Hang it at eye level by the toilet.
- Add a lidded trash can and spare liners.
- Tell guests and staff: only toilet paper goes in.
A free printable do not flush sign will not fix a pipe that is already blocked. It will stop a lot of the wipes, towels, and products that cause the next clog — which is the whole point.
