Learn how to make relaxing bath bombs with Simply Earth's new bath bomb supplies! This is an easy lavender bath bomb recipe that uses lavender essential oil and dried lavender buds for a beautiful bath bath bomb that's perfect for personal use or gift giving.

I've been getting the Simply Earth recipe box for a few years now, and I love getting the monthly box. It's a great deal, and it's a great way to learn about essential oils in small chunks at a time.

You can also buy single oils at fantastic prices, and they are adding a bunch of single ingredients now too. They offer free shipping on orders over $29 too.


They just added more bath bomb ingredients, so they had a special Bath Bomb week to launch it. They sent me a box of ingredients, so I got to play along at home.


I made the lavender bath bomb recipe because who doesn't need some more relaxation? I've made a lot of bath bombs, but this is the first time I've made one with emulsifying wax. I love that addition, and I'll be using it for bath bombs from now on.

Lavender essential oil is one of the most popular essential oils, so I used it for lavender bath bomb benefits. Lavender is said to be calming and can relieve stress and anxiety to help calm you.

Lavender bath products can help promote a calming sensation and reduce stress. It's a good option for before bedtime to help you relax.

Lavender bath bomb benefits are also for your skin because this is a good oil to promote skin health. Lavender is also soothing for your skin, so it's a good essential oil to use topically.

It's naturally anti-inflammatory and can promote skin health. Lavender can be used by most skin types, and it's good for body acne and dry skin.


I used lavender essential oil for my relaxing bath bomb recipe. Essential oils are natural, but they should still be treated with respect.

It's important to dilute them properly. Don't increase the amount used in this recipe because it can be too strong for lavender bath products. Use a printable dilution chart to guide you when making DIY recipes.

I also recommend the following blends for relaxing bath bombs:

Do Bath Bombs Ruin Bathtubs?

Generally, no your bath bomb will not ruin your bathtub. There are two things to be concerned about if you use them often.

First, any additives in the bath bomb can harm your pipes. Some bath bombs have coconut oil or other solid oils. Over time, the oils can build up in your pipes and cause a blockage.

Secondly, large additives like dried flowers or herbs can also clog pipes. These may collect in a septic tank.

I have a septic tank and an 1860s farmhouse with fickle plumping. I use bath bombs just a few times a year and scoop out any herbs that I use before draining.

Additionally, the mica used to color the bath bombs can leave a ring in your tub. You can eliminate this ring by using an emulsifier to bind the oils and mica with the water.

Most bath bomb recipes use polysorbate 80, but this easy lavender bath bomb recipe uses emulsifying wax.

Here's what you need to make lavender bath products and why you'll use each ingredient. Simply Earth carries these products, so you can get them all in one place!

Almond Oil - Almond oil is used to dilute the essential oil. It also helps bind the dry ingredients together. You can use any other carrier oil except solid coconut oil as a substitute. Learn more about carrier oils and their benefits.

Emulsifying Wax - Emulsifying wax is optional, but it helps the mica, almond oil, and essential oil mix with the water. It also helps harden the bath bombs.

Lavender Essential Oil - Lavender essential oil is relaxing and soothing for your skin.

Citric Acid - Citric acid helps create the fizz when it's combined with baking soda. It also naturally cleanses the skin.

Mica Powder - Mica is a natural colorant for bath bombs. It can stick on the tub and create a ring, so I recommend using emulsifying wax.

Lavender Buds - Dried lavender buds are pretty and promote skin wellness. They are optional.

Baking Soda - Baking soda helps create fizz when combined with citric acid. It's also soothing for your skin.


Cornstarch - Cornstarch creates a silky feeling. It also helps slow down the fizzing so the bath bomb lasts longer. You can also use arrowroot powder.

Isopropyl Alcohol - Water activates the fizz, so use a spray bottle with 99 percent isopropyl alcohol to spray the mixture to make it stick together to mold.

Bath Bomb Molds - I like to use metal bath bomb molds because they don't "give" when pressing the mixture into the mold. I used a 6.5 cm mold, but Simply Earth also has 4.5 cm.




In a medium sized bowl, combine the baking soda and cornstarch.


Place the almond oil and emulsifying wax in a small bowl. Heat in the microwave until the wax is just melted. I did 30 seconds and then another 15 seconds. Add the essential oil and stir well.


Pour the oil mixture into the dry ingredients. Stir with gloved hands. Spray with alcohol until the mixture holds it shape when you squeeze it. The amount that you need depends on the humidity in the air.


Stir in the citric acid and 1/8 teaspoon of purple mica powder until combined. It might fizz a little, but this is fine.



Add a pinch of lavender buds to one half of the bath bomb mold. Then fill one half of the mold and pack gently then overfill the mold until rounded. Then fill the other half of the mold in the same manner. Press both halves of the mold together and and twist gently.


If you have several molds, you can leave the lavender bath bombs in the molds to harden. Otherwise, carefully remove from the mold and set on a plate to harden. Avoid touching for several hours.
