DIY Bath Bomb Recipe

Despite the name, bath bombs do not actually explode in the tub. Instead, they slowly fizz away when thrown in warm bath water.

Imagine sinking into a long-awaited bath after a tiring day. The warm, relaxing water soothes away discomfort. The mind clears. Stress gives way to the delicious feeling of pure bliss.

Now imagine an amped-up version of this experience—one that is fizzy and fun with even more relaxing benefits. That’s a bath with a bath bomb.

Bath bombs also contain Epsom salt, which helps soothe muscles. All of these powdery ingredients bind together due to coconut oil, which also helps nourish skin. Some bath bombs may also contain food coloring, which can add an extra dimension to the bath bomb detonation, but that is optional.

You can find bath bomb molds on Amazon, Etsy or other stores that sell soap-making supplies. Some will have a section specifically for bath bombs, whereas others will group them with soap molds. For the record, soap molds do work for bath bombs.

Bath Bomb Ingredients:

  • 1/2 cup baking soda
  • 1/4 cup corn starch
  • 1/4 cup citric acid
  • 3-4 tsp. coconut oil
  • 1-2 tsp. water
  • 1 tsp. essential oil
  • Few drops food coloring (optional)

Bath Bomb Tools:

  • Bath bomb molds
  • Bowl
  • Whisk


Use more than one color. Separate your bath bomb mixture into as many bowls as you want colors, and follow the rest of the recipe as directed.

Round is the most common bath bomb shape, but why stop there? Search around on websites that sell bath bomb materials, and you will find a variety of bath bomb molds that include flowers, hearts, snowflakes and even cupcakes!

Bath bombs serve as a fun self-indulgence as well as an excellent gift. They are also easy to make, so why spend as much as $9 for one when you can make them yourself?
