bath bombs have become a popular addition to any relaxing bath routine. However, most store-bought bath bombs contain chemicals that can be harmful to the skin. If you want to enjoy the benefits of a bath bomb without the added chemicals, making your own natural bath bombs at home is a great alternative. In this article, we will go over step-by-step instructions on how to make natural bath bombs at home.


Before we start making the bath bombs, we need to gather all the necessary ingredients. Here's what you'll need:

  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup Epsom salt
  • 1/2 cup cornstarch
  • 3-4 tablespoons of natural oil (such as coconut oil or sweet almond oil)
  • Essential oils (optional)
  • Food coloring (optional)


In addition to the ingredients, you'll need some equipment to make the bath bombs:

  • Large mixing bowl
  • Whisk
  • Small bowl or container
  • Bath bomb molds (you can find these online or at your local craft store)


Now that we have all the ingredients and equipment, let's start making the bath bombs.

Step 1: Mix the Dry Ingredients

In a large mixing bowl, whisk together the baking soda, citric acid, Epsom salt, and cornstarch until well combined. Make sure there are no lumps in the mixture.

Step 2: Add the Wet Ingredients

In a small bowl or container, mix together the natural oil, essential oils, and food coloring (if using). Slowly add the wet mixture to the dry ingredients, whisking constantly. The mixture should start to clump together when you squeeze it with your hands.

Step 3: Pack the Mixture into Molds

Now it's time to pack the mixture into the bath bomb molds. Take a handful of the mixture and press it firmly into one half of the mold, making sure it's packed tightly. Repeat with the other half of the mold.

Step 4: Let the Bath Bombs Dry

Once you've packed the mixture into the molds, let them dry for at least 24 hours. You can speed up the drying process by placing the molds in a warm, dry place.

Step 5: Remove the Bath Bombs from the Molds

After 24 hours, gently tap the molds to release the bath bombs. If they don't come out easily, try gently twisting the molds to loosen the bath bombs.

Step 6: Store the Bath Bombs

Store the bath bombs in an airtight container or bag until you're ready to use them.

Tips and Tricks

  • If you're using food coloring, be careful not to add too much as it can stain your skin or bathtub.
  • Experiment with different essential oil combinations to find your favorite scent.
  • To make the bath bombs more luxurious, add dried flowers or herbs to the mixture.
  • If the mixture is too dry, add a little more natural oil to help it stick together.
  • If the mixture is too wet, add a little more baking soda and citric acid until it reaches the right consistency.
