Wondering if you can bring bar soap on a plane? The answer is yes! Discover TSA-friendly tips and 9 more low waste travel hacks for eco-conscious trips.
Planning a trip and wondering what low waste essentials can make it through airport security? One of the most common questions we hear is: Can you bring bar soap on a plane?
The short answer is yes! Bar soap is solid, not liquid, which means it’s not subject to TSA liquid restrictions. It’s a win-win for minimalists, sustainability lovers, and frequent flyers alike.
Whether you’re flying carry-on only or just looking to simplify your travel routine, bar soaps are a TSA-friendly staple that save space, reduce waste, and minimize spills. Let’s dive into the details (plus, nine more low waste travel hacks to make your next adventure kinder to the planet!).
First Thing First: Can You Bring Bar Soap on a Plane?
Absolutely. The Transportation Security Administration (TSA) allows solid bar soaps in both carry-on and checked baggage
Because bar soap doesn’t fall under the 3.4 oz (100 ml) liquid rule, you can pack as many bars as you like (within reason and space). This applies to body soap, shampoo bars, conditioner bars, and even facial cleansing bars.
If you're traveling internationally, the rules are generally similar across countries, but it's always a good idea to check local airport guidelines. Generally, solid toiletries like bar soap make a great alternative to liquids, especially when you're packing light and aiming for a more sustainable travel routine.
How To Travel With a Bar Soap (Without The Mess!)

To make the most of your soap bars on the go, consider these smart storage tips:
Dry Before Packing
Let your bar dry completely before packing it. A dry bar lasts longer and is less likely to become mushy or messy.
Use a Tin or Soap Saver
A dedicated travel tin or container keeps your bar protected and contained. Look for containers with drainage holes or soap savers to extend the bar’s life.
Cut It Down
For shorter trips, slice off a portion of the bar instead of bringing the whole thing. This saves space and weight.

Bar soap isn’t the only way to travel more sustainably. Here are 9 other low-waste travel hacks to consider:
1. Ditch the Travel-Sized Bottles
Instead of single-use plastic minis, opt for refillable silicone bottles or go solid: think bar shampoo, toothpaste tablets, or solid lotion bars.

Skip disposable plastic by carrying a compact bamboo or stainless steel utensil set.
3. Bring a Reusable Water Bottle
Staying hydrated without single-use plastic is easy when you have a collapsible or insulated water bottle. Fill up post-security!

Think reusable cotton rounds, facial cloths, and menstrual cups. They’re hygienic, compact, and waste-free.

Flying has a big carbon footprint. Offset your emissions through certified programs like Gold Standard or TerraPass.

Go paperless where possible: digital tickets, eBooks, and maps reduce waste and keep things organized.
