Ingredients for Making CBD Bath Bombs

Before we go into the process of making CBD bath bombs, let's first take a look at the ingredients you'll need.

1 cup baking soda

1/2 cup citric acid

1/2 cup cornstarch

1/2 cup Epsom salts

3 tbsp coconut oil

2 tbsp shea butter

Essential oils of your choice (optional)

Food coloring (optional)

CBD oil (start with 5-10 drops and adjust to your desired amount)


  • Mixing bowl
  • Spoon or spatula
  • Bath bomb mould (or you can use ice cube trays or silicone muffin cups)
  • Spray bottle with water

Step-by-Step Instructions for Making CBD Bath Bombs

Step 1: Combine dry ingredients

In a large mixing bowl, combine the baking soda, citric acid, cornstarch and Epsom salts. Stir the ingredients together until they are well combined and there are no clumps.

Step 2: Add the oils

Next, add the coconut oil and shea butter to the bowl. Mix the ingredients together until the oils are evenly distributed throughout the dry ingredients. You can also add essential oils at this point, if needed. Essential oils are great for your skin and mind. When you add them to your bath bomb, they make it even more relaxing and enjoyable.

Step 3: Add the CBD oil

Next, add the CBD oil to the bowl. CBD oil can provide a variety of benefits for the body and mind, including pain relief, reduced anxiety and improved sleep. Start with 5-10 drops of CBD oil and adjust to your desired amount, taking into consideration the strength of your CBD oil.

Step 4: Mix in water

In a spray bottle, mix together 15-20ml of water with a few drops of food colouring, if required. Slowly add the water to the bowl, mixing the ingredients together as you go. You want the mixture to be wet enough to hold together when you press it into the mould, but not so wet that it fizzes or starts to react with the citric acid. If the mixture is too dry, you can add a little more water and if it's too wet, you can add a little more dry ingredients.

Step 5: Fill the moulds

Once the mixture is the right consistency, it's time to fill the moulds. Spoon the mixture into the moulds, pressing it in firmly and making sure it's evenly distributed. Once the moulds are full, use your hands or the back of a spoon to press the mixture in even further and make sure it's packed tightly.

Step 6: Let them set

Let the bath bombs set in the moulds for at least an hour, or until they are fully dry and firm. Once they're ready, gently pop them out of the moulds and store them in an airtight container until you're ready to use them.

Step 7: Enjoy!


While these ingredients are harmless for use in the bathtub, it's important to remember that bath bombs are not for consumption.

Using and Storing Your CBD Bath Bombs

Using and storing your CBD bath bombs properly can ensure their longevity and effectiveness. Here are some tips to keep in mind:

  1. Use the bath bomb immediately or store it properly: 

Once you’ve made your CBD bath bombs, it’s best to use them as soon as possible to ensure the effectiveness of the ingredients. If you’re not planning on using them immediately, store them properly to extend their shelf life.

  1. Store in an airtight container:

The best way to store your CBD bath bombs is in an airtight container. This will help prevent moisture from getting in and causing the bath bombs to break down or lose their fizz.

  1. Keep away from moisture: 

Moisture can be the enemy of your CBD bath bombs, so it’s important to store them in a dry place. Avoid storing them in the bathroom where there’s a lot of moisture, as this can cause them to lose their effectiveness or break down.

  1. Check the shelf life: 

CBD bath bombs typically have a shelf life of 6 months to a year, depending on the ingredients used. Be sure to check the shelf life of your specific recipe and use them within that timeframe to ensure maximum effectiveness.

  1. Use a full bath bomb: 

Using a full CBD bath bomb can ensure that you’re getting the full benefits of the ingredients. Breaking the bath bomb in half or using less may not provide the same level of relaxation and effects.

  1. Experiment with different water temperatures: 

The temperature of the water can affect the effectiveness of the CBD bath bomb. Experiment with different water temperatures to find the perfect balance of relaxation and therapeutic benefits.

  1. Rinse off after the bath: 

After using your CBD bath bomb, be sure to rinse off in the shower to remove any residue. This can help prevent any irritation or sensitivity that may occur from leaving the residue on your skin.

Enjoying the full benefits of your DIY CBD bath bombs

Finally, it’s time to enjoy the full benefits of your homemade CBD bath bombs. As the bath bomb dissolves, the CBD oil and other ingredients infuse the bath water with beneficial properties, providing a soothing and relaxing experience for the skin and the body. The CBD oil works to hydrate and nourish the skin, helping to relieve dryness and improve overall skin health. The warm bath water helps to open up the pores, allowing the CBD oil and other natural ingredients to penetrate the skin more effectively, providing deeper hydration and nourishment. The other ingredients, such as essential oils and Epsom salt, add to the overall relaxing and rejuvenating experience, leaving the skin feeling refreshed and revitalised.

Whether you're looking to unwind after a long day or to simply pamper yourself, a CBD bath bomb can provide a soothing and rejuvenating experience that can help you feel refreshed and revitalised.
