I’ve always wanted to know how to make a bath bomb. Similar to bath salts, they are a fun project. And guess what? They are actually super easy and a great gift. And homemade bath bombs are so much better than the store-bought versions. Here’s a four-step fool-proof process to make your own DIY bath bombs.
Gather your DIY bath bomb ingredients
Now, a lot of these products might seem kind of expensive at first, they should last you a really long time. Here’s a list of everything that you’ll need to make your homemade bath bombs:
- Citric acid (this creates a chemical reaction in the bath water)
- Essential oils or fragrance oils (choose your favorite scents)
- Epsom salt (fragrance free)
- Baking soda
- Corn starch (this helps hold everything together)
- Food coloring (liquid)
- Baby oil or castor oil, coconut oil or almond oil
- Aluminum molds or silicone molds
Step #1: Mix dry bath bomb ingredients
For this DIY bath bomb recipe, you’ll want to start off by combining all of your dry ingredients in a large mixing bowl. Add 1/2 cup of baking soda, 1/4 cup of Epsom salt, 1/4 cup of cornstarch and 1/4 cup of citric acid. Combine with a whisk and set aside.
Step #2: Mix wet bath bomb ingredients
Next, in a small cup, you’ll need to mix all of the wet ingredients into an oil mixture. Start by adding 1 tablespoon of water, 3 teaspoons of baby oil, 1 tablespoon of your favorite essential oil, 3 drops of liquid food coloring. Mix everything together with a spoon. Make sure that the food coloring has mixed well so you don’t end up with clumps in your bath bombs. You can add only a few drops of essential oils in you want to make them last longer.
Step #3: Combine the wet and dry ingredients
Slowly pour the liquid mixture into the bowl with the dry ingredients a little bit at a time. If you pour it all in at once, the carbon dioxide and sodium bicarbonate will activate and the bath bombs won’t fizz. Just a few drops at a time works great. You’ll slowly start to see the fluffy, colorful substance come together. It should have the texture of wet sand.
Step #4: Form your bath bombs
This last step is crucial. I didn’t do it right the first couple of tries and ruined two batches of bath bombs. Using both sides of your aluminum bath bomb mold, scoop a heaping amount onto each half. Don’t pack the mixture into the mold. Then, quickly close the two halves together and press.
Then, holding the mold in your hand, lightly tap both sides of the mold to loosen the mixture. Take off one side of the mold and then gently remove the other side and set it on a cookie sheet to rest.
Refrigerate all of the completed bath bombs in an air-tight container or cover with plastic wrap in a dry place for 24 hours or a couple days until completely dried. If you just leave them on the counter to harden, they will start to sag and droop. They will end up looking like slightly melted bath bombs. Here’s a short video of how I made these colorful bath bombs:

Homemade bath bomb tips and tricks
Here’s just a reminder of some dos and don’ts to make sure that your bath bombs turn out perfect:
- Don’t pack into the mold
- Overfill each half of the mold, close and press
- Gently tap the mold before removing it
- Don’t dry the bombs in the mold
- Put the bath bombs in the fridge to dry so they don’t sag or “melt”
- Try using scented Epsom salt instead of essential oils to save money
- Add rose petals, lavender buds or other flower petals for an added depth
- If you don’t own a mold, try ice cube trays, plastic easter egg or a muffin tin
