DIY LUSH Bath Bomb

I‘ve been home for just over a week. It’s been so nice to relax and enjoy seeing my family and friends. One of the things I missed most about home (besides the aforementioned family and friends!) was my weekly spa sessions. I love putting on a face mask and taking a long bubble bath and just decompressing. But at school, I don’t have the luxury of a bathtub. So since I’ve been home, I’ve loved relaxing in the tub. And what better way to relax than with a bath bomb? I have no shame in admitting my addiction to LUSH, but their bath bombs can be pretty expensive. So I adapted this recipe for a DIY LUSH bath bomb that’s just as colorful and fizzy as the ready-made version.

This recipe includes good-for-you epsom salt and relaxing essential oils. Check out my recipe below!

Yield: 2 large bath bombs


8 oz baking soda

4 oz citric acid

4 oz cornstarch

4 oz Epsom salt

2 tsp essential oil (I used this citrus botanical blend and this lavender oil)

1 tsp oil (I like coconut or olive oil)

3/4 tsp water

Food coloring (whatever color you like!)

Round plastic molds (I got mine at Michael’s, but you can use any plastic mold or those fillable plastic ornaments, like these)


  1. Combine the dry ingredients in a large bowl. Whisk until all the clumps are gone.
  2. Combine the wet ingredients in a separate bowl. If you use coconut oil, melt it a bit before combing with the water, food coloring and essential oil.
  3. Slowly pour the wet ingredients into the dry ingredients, whisking as you go. If the mixture starts to fizz, you’re probably adding the wet ingredients too quickly.
  4. Once all ingredients are combine, squeeze some of the mixture in the palm of your hand. It should stick together fairly well. If it’s still too powdery, add a small amount of water until the mixture holds together.
  5. Fill each half of your plastic mold with mixture until it’s overflowing just a little. You want them to overflow so the two halves stick together in the next step.
  6. Carefully press together the two halves of your mold. After a few minutes, gently remove one side of the mold.
  7. Place the bath bombs on a tray and allow to dry for about 10 minutes before gently removing the other mold.
  8. Allow the bath bombs to dry overnight before using.


These can fall apart on you very easily, so the key to these DIY lush bath bombs is handling them very gently. They can also crack as you take them out of the mold (it happened to me at least once). If this happens, you can gently press the sphere back together or restart the molding process.
