This is a fun twist on the classic DIY bath bombs recipe.
If you’ve never made your own bath bombs before, I can highly recommend it! DIY bath bombs are a lot easier to make than you’d expect, and you can customize them with your own, scents and colors.
Just like I did with this recipe. Instead of coloring the mixture, I colored the salts. The effect turned out even better than I could have imagined!
Choose your favorite color (Pink or blue for a baby shower? Red and green for Christmas?). Add your favorite essential oils and you have the perfect homemade gift.
Or keep them all for yourself. Because these DIY bath bombs are the perfect relaxing spa treat!
This recipe makes about 1 giant bath bomb (LUSH size) or about 3 medium sized ones. You can easily double or triple the ingredients to make more.

1. Color your salts
Divide 3 tablespoons of Epsom salt between 2 bowls. Add one drop of food coloring to one bowl and add a drop of another color to the other. Add more drops for a more intense color. Let the salts sit while they soak up the dye.
Divide the salts over more batches if you want to use more colors.
2. Combine your dry ingredients
Put the baking soda, cornstarch and citric acid in a large mixing bowl. Whisk together with a spoon or fork.
This would also be the time to add your essential oils. I used 6 drops of ylang-ylang and 6 drops of lavender.
Lavender is a great choice for its relaxing properties and ylang-ylang has a beautifully sweet scent.
3. Add the coconut oil
Add 1 heaping tablespoon of coconut oil to your dry mixture. Mix all the ingredients together and make sure to smooth out all the lumps.
If you want you can melt the coconut oil first. This will make it easier to mix the oil with the rest of the ingredients.
If for some reason you prefer to not use coconut oil (for example if you’re allergic), you swap it with another carrier oil, like olive oil or almond oil.
4. Spritz with witch hazel
Take a handful of the mixture and squeeze it together with your fingers in the palm of your hand. The powder should clump together.
If it doesn’t you can spritz it lightly with some water (or witch hazel) in a spraying bottle.
Stir well between each spritz and make sure the mixture doesn’t start to fizz in the bowl! Check regularly to see if the mixture clumps together.
Once the mixture looks like damp sand, it’s ready.
5. Create your DIY bath bombs
Add the colored salts to the batch. Carefully stir the salts into the mixture.
I put a few salts at the bottom of my mold because, well, it looks pretty! Fill your mold one spoonful at a time. Press the mixture down firmly after each scoop.
Let your mold sit for a few hours or – if you can wait long enough – overnight. Carefully take the bath bomb out of its mold and wrap as a gift or keep for yourself!
