How to Make CBD Oil Bath Bombs at Home

CBD oil bath bombs are excellent for easing anxiety and finding pain relief. Learn how to make your own CBD oil bath bomb like a pro! All it takes are a few ingredients that you probably already have, and a little creativity. These CBD oil bath bombs can be made at home from the comfort of your kitchen, and they also make perfect gifts.

What You Need to Make CBD Oil Bath Bombs

Lets review the tools you will need to get started. Be prepared to get a little messy, as packing and unpacking the molds can get intense.

  • Disposable Gloves
  • Mixing Bowl
  • Whisk
  • Bath Bomb Mold
  • Digital Kitchen Scale or Measuring Cups

To make more or less bath bombs, simply multiply or divide the ingredient list to suit your needs. For first timers we suggest starting small while you perfect your technique.

Bath Bomb Base Ingredients:

  • 2 Cups Baking Soda
  • 1 Cup Citric Acid
  • 1 1/2 Cups Corn Starch
  • 1/2 Cup Epsom Salt
  • 2–4 Tablespoons Water
  • A few drops of paste gel food coloring (optional)
  • A few drops of Essential Oils to taste (optional)

Determining How Much CBD Oil to Use

If you are familiar with CBD oil, you probably know that it comes in many different forms and strengths, from CBD oil tinctures, to edibles and even pet treats! For this recipe, we want to use plain CBD oil or CBD Isolate to ensure accurate and consistent dosing. Depending on what type of results you are seeking from your bath bomb, you may use more or less CBD oil. We suggest making a few CBD oil bath bombs with different concentrations to find which one works best for you.

CBD content is generally measured in Milligrams (mg) per ounce. For example, our CBD oil body balmscontain 150mgs of CBD per fluid ounce. The minimum amount of CBD oil for a relaxing bath bomb is about 25mg of CBD oil total. If you are seeking pain relief, try between 50–100mg CBD oil per bath bomb. For deep relaxation and pain relief you may want to try adding up to 200mg of CBD oil per bath bomb.

The tricky part is figuring out the total amount of CBD oil you need to add to your entire bath bomb mixture. Here’s how to figure it out:

In order to have the same amount of CBD in each bath bomb, multiply the desired amount of milligrams per bath bomb by the number of bath bombs you are making.

To make a quantity of 10 extra-large 5 ounce bath bombs, with 25mgs of CBD oil per bath bomb, you will need a total of 50 ounces bath bomb mix made with a total of 250mgs total of CBD oil.

Pharma Hemp Complex Isolate Powder

CBD Isolate Powder can be easily added to your recipe, and is the best method for first time bath bomb crafters as this dry powder will blend well with the dry base. Pharma Hemp Complex CBD Powder Isolate is 99% pure CBD, meaning a little bit goes a long way. If we follow the dosage example above, you will need to measure out 250mgs of isolate powder using a digital scale. Alternatively, you can use a teaspoon to measure milligrams using this guide.

Note: CBD Isolate does not include the full spectrum of cannabidoids.

Pharma Hemp Complex 25% Pure Gold Oil

Get the all benefits of full spectrum CBD oil with this 25% Pure Gold Oil. 1 gram of Pharma Hemp Complex gold oil contains 250mgs of full spectrum CBD. So, if you want to follow the dosage example above, simply add the whole gram into your mix. To ensure even mixing, we recommend softening the oil before adding it to the mix. To do this place the sealed syringe in warm water for about 5 minutes. Mix in the gram incrementally by adding a rice grain sized amount at a time.

Bath Bomb Mixing and Molding

When making a CBD oil bath bomb you will be combining the dry ingredients first, and slowly adding the wet ingredients. Make sure your dry ingredients are clump free before adding the wet ones. The trick is to combine the two without fully activating the dry ingredients. You don’t want your bath bombs to fizz up before they make it to the bath!

When adding the wet ingredients, do so incrementally, while whisking. If a fizzy area appears, quickly mix it in with the rest of the ingredients to diffuse the situation. You may want to set aside extra dry ingredients to quell premature fizz ups. The mix should hold its form when you squeeze a handful of it and let go.

These bath bomb molds can be purchased here on Amazon.

Once you have your CBD oil bath bomb mix prepared, you will need to pack the mix into a mold. Metal molds do better than silicone ones as you will need to apply a lot of pressure to the mix to keep it sticking together. Spherical and fun shaped bath bomb molds such as these can be found on Amazon. For added fun and seasonal spirit, you might prefer using a holiday muffin pan such as this one. Keep in mind that designs with parts that branch off, like a wing for example, will be more difficult to unmold than round compact designs.

Think: “Sand Castle”

Pack the mix into your mold as tightly as you possibly can. If your mold has an embossed design, start by packing those areas before filling the entire mold. Pack the mix in bit by bit, don’t try to pack too much at once. If you are using a baking pan for a mold, smooth the top down so it is distributed evenly. An uneven surface will make cracking more likely. Let the mixture rest in the mold for about 5–10 minutes.

Un-mold your mixture very slowly, think “sand castle reveal”. If you are using an open facing mold, place a cookie sheet over the open surface of the mold and hold the two together tightly. Now, flip the pan over and set it down on a table. Slowly lift the mold, leaving the bath bombs on the cookie sheet. For spherical molds, simply open the mold, keeping it held close to the table top to avoid it dropping, and breaking.

If your CBD oil bath bomb cracks or crumbles during this process, simply try again. Pack that same mixture back into the mold, adding a spritz of water if needed.

Now — We Wait

By now you are probably really eager to take your freshly molded CBD oil bath bombs into the bath so you can finally relax! Before you do that, you need to allow them to dry overnight. If you are a first time bath bomb crafter, or if you are having trouble un-molding without breaking, you may want to let them dry overnight within their molds. If you are a clean, lean, un-molding machine, you can let them dry in the open air on a flat surface.


Once your CBD oil bath bombs are dry, you can toss one in a hot bath, or wrap them up pretty for gift giving! Be sure to store in a cool, dry place where they will not be disturbed to avoid breakage.
