How to store bar soap so it lasts as long as possible? This is a common question that often puzzles many people. Well, it turns out that storing your soap properly can have a significant effect on how long it can last — from a few weeks to several months!

We will discuss a few options in this post and help you choose what’s best. But first, let’s talk about why storing your soap properly is important. We will also share some tried-and-tested tips to keep moisture out of your bars as much as possible.

Why is Proper Soap Bar Storage Important?


There are many reasons why you should store your soap the right way. First, it will remain in good condition and make bar soap last longer than usual and ultimately help you save soap bars in the long run.

Properly storing soap bars also prevents mildew and mold growth that can occur when moisture gets trapped inside the bar. Molds can lead to unpleasant smells and unsightly spots on your soap. Not only will this affect the quality of the soap, but it will also make it less effective when used on your skin or in a bath.

You’d want to avoid this, especially if you have sensitive skin or allergies, because moldy or discolored bars of soap can irritate your skin even more than usual.

Next, improper storage can lead to wasted money on buying new bars of soap when old ones should still be usable.

Also, you could do your part to help reduce waste by preventing excess packaging from going into landfills prematurely due to poor storage habits.

What Are Common Items You Will Need to Store Soap the Right Way?

  • Airtight containers such as a ziplock bag with silica beads
  • Alternatively, you can use plastic wrapper/wax paper for your bars so long as there are no gaps when you wrap them
  • Soap dishes (or wooden draining racks) that offer good drainage and as little surface contact as possible

What is the Best Way to Store Bar Soap That is Used Daily?


What to do:

  • The first step is to choose the right location for your soap. You should always store it in a cool, dry place away from direct sunlight and other sources of heat.
  • If you’re not using your soap every day, it’s best to keep it in its original packaging or in a plastic bag.
  • Put your soaps on a tray or in a dish that allows water to drain off. This will keep water from getting into your soap dish and causing mold growth.
  • Use separate boxes or trays for each type of soap to avoid the different ingredients in each soap having adverse reactions with one another.
  • If you have no choice, especially if you’re in college dorms, and must store your soap in the bathroom, make sure that it is well-sealed so that air cannot get into it from either side (top or bottom).
  • If possible, use a container that is airtight or has an airtight lid like ziplock bags. This will help prevent the moisture in the air from causing the soap to spoil prematurely.

What not to do:

  • While storing bar soaps on open shelves may be convenient, this can expose them to dust and dirt particles which will reduce their shelf life considerably.
  • It’s also not recommended to store bar soap in shower areas because of the high humidity levels which can cause mold growth on wet surfaces; this is especially true if you leave the lid off your soap container for long periods of time.
  • If you plan on using your bar of soap again soon, especially for travel, make sure not to store it in a container that is too wet or damp. This will cause the soap to dissolve more quickly than usual.

How About Long-term Soap Storage?


Crafting your own soap bars is a fun and potentially lucrative hobby. You’ll find plenty of recipe ideas on Reddit from users who have first-hand experience.

But aside from learning soap-making, you must also know how to store homemade soap for the long run. Otherwise, your batches won’t last and you’ll be losing money.

  • A simple shoe box is best as a soap storage box for longer periods. If you prefer to have better protection agains dust and insects, a loose top or a cover with a few holes would do nicely.
  • Use plastic wrap or wax paper to wrap each bar of soap. This will help keep it from drying out while still allowing air circulation around each bar of soap so it doesn’t get moldy or mildewed inside its wrapper.

Important Notes for Long-term Soap Storage

  • As much as possible, don’t store your bars on top of one another — this can cause them to bend and break over time.

Instead, spread them out flat on their sides so that there’s equal weight distribution across all sides of each bar. If there’s no choice, at least give a little space between each bar for air circulation.

How Long Can You Store a Bar of Soap?

Although you can store your soap for about 30 months, we recommend using it within six months of purchase especially for handmade ones to ensure freshness and quality.

What Should I Look for When Buying Soap Bar Containers?


When looking for a soap container, there are some things to keep in mind:

  • The first thing to consider when buying a storage container for your bar soap is whether or not it will be used in the shower or tub.
  • If you want to keep the soap out of water completely, then you’ll need to find a container that can be sealed tightly so that moisture cannot get inside.
  • If you don’t want to seal off the container completely, then look for something that allows some airflow so that moisture doesn’t build up inside the container while still keeping water out of your soap itself.
  • There are many different types of containers that can be used for storing bar soaps, but most people prefer plastic containers because they’re readily available, inexpensive and easy to clean.
  • If you plan to store several bars in one container, make sure it has enough room for all of them without being too crowded. A good rule of thumb is to let each bar have about an inch of space around it (1/2 inch if the bar has been cut).

Otherwise, you run the risk of having the bars stick together and jamming up inside their container when you try to take them out again later on.


If you want your bar soap to stay strong and last as long as possible, these tips will help you on how to store bar soap correctly.

However, there’s really no one right way to store it—the soap needs to breathe in order to dry out properly, and the best way to do that while preserving it as long as possible is up for debate.

Think about where you’ll be storing your soap, what kind of space you’ll have, and how much moisture can build up in that area before making a decision about how to store it.
