How to Dry Bath Bombs Quickly?

If you make bath bombs at home, you know that they can take a few days to dry completely. However, there are different ways to speed up the drying process so that they are ready immediately. This blog post is for making a bath bomb and includes information on oven drying times and humidity.

It is best to dry the bath bombs quickly, letting them sit for 48 hours, and then bake them for 2 hours on minimal heat. Bath bombs placed in the oven too early or too much heat will expand and crumble when removed. The stove isn’t the only option, but it can help in humid climates, so let’s look at other ways to make quick-drying bath bombs at home.

Use Less Water and Oil

To make a bath bomb, you need oil [for taste and adhesion] and water [to help mix], but if you use too much, the drying process will prolong with few options for speeding it up. If possible, use the smallest amount of essential oil, just a few drops, and use witch hazel instead of water for the final mixing and packing process.

Your bath bombs will dry faster if there is less moisture in the mixture. It’s a perfect thing if you can avoid using the dryer. When you evaporate the water in the bath bomb at a faster pace than usual, you risk the bath bomb expanding, splitting, and collapsing because the outer region dries more rapidly than the inner.

Allowing a handmade bath bomb to dry in the air overnight is excellent. Air drying takes 6-8 hours to harden fully, but drying in the oven can reduce that time to less than an hour.

Only use the oven to dry your bath bombs if you need to dry quickly for a specific purpose or if you live in a humid environment. Air drying is recommended since it does not ‘force’ dry the moisture, resulting in finished product stability issues.

Drying in the Oven

A bath bomb that has been dried in the oven is not the same as a bath bomb cooked!! If the heat is too high, the moisture will evaporate too rapidly. The outside of the pump hardens and compresses much faster than the inside.

The humidity in the middle will get very hot, and you must leave. In this case, the bath bomb will most likely expand and rise like a loaf of bread, and you’ll get the same outcome with the surface breaking and crumbling to let the hot liquid out.

If you plan to use the oven to dry your bath bombs, set the value to the minimum. When the oven reaches the desired temperature, please turn it off and put the bath bombs inside for 45 minutes to an hour while the oven cools.

Drying by Air

The best way to dry bath bombs is to leave them out in the open for a total of 24 hours. It can be wrapped after 68 hours in drier areas, but do not pack within 24 hours to avoid sealing residual moisture in the package.

Parchment Paper

Setting your bath bombs aside on a tray with parchment paper to dry would be sufficient, but using a tray with a baking soda foundation [like a sand pit] will give a softer base. It can also help remove moisture. Placing it on smooth surfaces can also help prevent the bottom of the bath bomb from swaying.

Giving the bath bombs a spin every few hours if you have to leave them on a hard surface to dry can also assist them as spherical as possible.


Some bath bomb organizations have told me that putting them in the fridge in hot regions has worked. We wouldn’t recommend it unless you have a specialized fridge, especially if the candles are intensely aromatic. Essential oil smells are relatively strong, and I wouldn’t want any of them to transfer to my meal.

This rule only applies if you used coconut oil in your bath bombs, solidifying at low temperatures. However, you will most likely need a few minutes, and the freezer may be a better alternative.


Once your bath bombs are produced, you may store them in the freezer. It is possible if you’ve used coconut oil or another carrier oil that solidifies at lower temperatures.

Clay Kaolin:

Finally, if you want to expand your bath bomb company, you should consider including Kaolin Clay in your formula. It was a huge game-changer for us when we initially started utilizing it. When we took the bath bombs from the mold, they quickly became more durable, and they were dry enough to transport within 3 hours if required.

The only true disadvantage of using kaolin clay was the additional upfront cost. Still, when we crunched the figures at the end of the month, we discovered that the cost of the kaolin clay was compensated by the amount of product we didn’t lose due to crumbled bath bombs. So it was a no-brainer for us, and we’ve been utilizing it in all of our bath bombs since.

One (very essential) caution is that Kaolin Clay is powdered, therefore as with other powdered materials, you should always want a dust mask or respirator when handling it to avoid inhaling the powder.

One of the major concerns for DIY bath bomb manufacturers is humidity. Low humidity and too high humidity can make it difficult for the mixture to dry too quickly before placing it in the mold. Humidity may be a perplexing aspect of production.


The last phase of creating the ideal bath bomb is frequently neglected after the work of obtaining and mixing your bath bomb components, molding them in the mold and removing them to dry.

Suppose you’ve been having trouble drying your bath bombs and came to this article. As a result, we hope you find your way to more stable bath bombs by employing one of these methods throughout the drying process.


When it comes to bath bombs, how long do they take to dry?

The solution you choose will determine how long it takes to dry your homemade bath bombs. Allowing a handmade bath bomb to dry in the air overnight is great. Air drying takes 6-8 hours to harden fully, but drying in the oven can reduce that time to less than an hour.

Is it possible to dry bath bombs in the oven?

Using a muffin tin or an ice cube tray (If using a muffin pan, dry the bath bombs in the oven for 45 minutes or overnight at room temperature). If you reside in a humid climate, oven drying the bath bombs is suggested.

What is the best effective way to harden a bath bomb?

If you live in a very humid location, investing in a dehumidifier to keep things dry while you work a good idea. To balance things out, add additional baking soda or citric acid. One teaspoon of kaolin clay per cup of powder can also add, and it aids in the hardening and shaping of bath bombs.
