Making your own bath bombs is easier than you might think. With a few basic ingredients, you can create neem oil bath bombs at home and customize them with different oils, scents, and other ingredients.
Neem oil is especially interesting for DIY skincare because of its unique plant-based composition and long history of use in personal care products. It does have a strong, earthy aroma, though, so knowing how much to use makes a big difference.
In this guide, we'll show you how to make bath bombs with neem oil step by step, along with tips for customizing, storing, and troubleshooting your homemade bath bombs.
What Is Neem Oil?
Neem oil is a plant-based oil pressed from the seeds of the neem tree (Azadirachta indica). It has a thick consistency and a naturally strong, earthy aroma.
Neem has a long history of use in traditional personal care practices. Today, you'll find neem oil in soaps, lotions, shampoos, and other skin and hair care products.

Cold-pressed neem oil can also be incorporated into homemade bath bombs and other DIY skincare recipes. Because of its strong natural scent and concentrated consistency, you don't need a large amount to get started.
Why Add Neem Oil to Bath Bombs?
Adding neem oil is an easy way to put a different spin on a basic DIY bath bomb recipe. It adds a plant-based oil to the mixture and gives the finished bath bombs neem's recognizable herbal aroma.
Making your own bath bombs also gives you more control over the ingredients. You can keep the recipe simple or experiment with different carrier oils, fragrances, and herbs.
DIY neem bath bombs are:
- Easy to make at home
- Made with simple ingredients
- Customizable based on your preferences
- Easy to store for future baths
- A creative way to use cold-pressed neem oil
If you're new to neem, start with a simple recipe before adding a long list of extra ingredients.
How Much Neem Oil Should You Put in Bath Bombs?
Neem oil has a naturally strong aroma, so a little can go a long way. Our neem oil bath bomb recipe uses two tablespoons in a batch containing one cup of baking soda.

If you prefer a lighter neem scent, you can experiment with using less in future batches.
Changing the amount of neem oil can also change the consistency of your bath bomb mixture. You may need to adjust the amount of witch hazel or water slightly to get a mixture that holds together without becoming too wet.
Easy Neem Oil Bath Bomb Recipe
Ready to make your own? This simple recipe combines neem oil with common bath bomb ingredients like baking soda, citric acid, Epsom salt, and cornstarch.
Ingredients
- 1 cup baking soda
- ½ cup citric acid
- ¼ cup cornstarch
- ¼ cup Epsom salt
- 2 tablespoons cold-pressed neem oil
- Witch hazel or water, as needed
- Optional: skin-safe essential oil or fragrance
Supplies
- Large mixing bowl
- Spoon or whisk
- Measuring cups and spoons
- Bath bomb molds
- Small spray bottle
- Gloves

Step 1: Mix the Dry Ingredients
Add the baking soda, citric acid, cornstarch, and Epsom salt to a large mixing bowl.
Use a whisk or spoon to break apart any clumps and thoroughly combine the ingredients.
Step 2: Add the Neem Oil
Slowly add the neem oil while continuing to mix. Try to distribute the oil throughout the dry ingredients rather than pouring it all into one spot.
Step 3: Add Optional Fragrance
If desired, add a small amount of a skin-safe essential oil or fragrance.
Neem oil already has a noticeable natural scent, so you may want to keep additional fragrances light.
Step 4: Add Witch Hazel
Fill a small spray bottle with witch hazel and lightly mist the mixture while stirring continuously.
Don't pour liquid directly into the bowl. Adding too much at once can activate the citric acid and baking soda before the bath bombs reach the tub.
The mixture is ready when you can squeeze a handful, and it holds together without immediately crumbling.
Step 5: Fill the Bath Bomb Molds
Firmly pack the mixture into your bath bomb molds. Press down to remove loose areas and help each bath bomb hold its shape.
Step 6: Let Them Dry
Allow your homemade neem bath bombs to dry for at least 24 hours.
Once completely dry and firm, carefully remove them from the molds and transfer them to an airtight container.

Understanding what each ingredient does makes it easier to adjust your natural bath bomb recipe later.
Why Are My Bath Bombs Falling Apart?
Bath bombs can take a little practice. If your first batch isn't perfect, the problem is usually easy to fix.

The Mixture Is Too Dry: If your mixture crumbles when squeezed, lightly mist it with additional witch hazel. Mix thoroughly before adding more.
The Mixture Starts Fizzing: Fizzing during preparation usually means you've added too much liquid too quickly. Use a spray bottle and add only a small amount at a time.
The Bath Bombs Break When Removed: Make sure you're packing the molds firmly. You may also need to give the bath bombs additional drying time before removing them.
Ways to Customize Your Neem Bath Bomb Recipe
Once you've mastered the basic recipe, you can start experimenting.
Add another carrier oil: Small amounts of coconut, jojoba, or sweet almond oil can change the feel of your finished bath bombs.
Experiment with fragrance: A skin-safe essential oil or fragrance can help complement neem's natural aroma. Always follow appropriate usage and dilution instructions for the specific ingredient.
Keep them simple: There's nothing wrong with skipping additional fragrances, colors, or dried flowers. A basic bath bomb recipe with neem oil only needs a handful of ingredients.
Making smaller experimental batches can help you find the combination you prefer without wasting ingredients.
How to Store Homemade Neem Bath Bombs
Moisture is one of the biggest enemies of homemade bath bombs. Once they're completely dry, place your DIY neem bath bombs in an airtight container and keep them somewhere cool and dry. Avoid storing them near showers, sinks, or other areas with high humidity.

Exposure to moisture can cause the baking soda and citric acid to begin reacting early, which may leave you with less fizz when you finally add the bath bomb to water.
Tips for Using Neem Oil Bath Bombs
Everyone's skin responds differently to skincare ingredients. If you've never used neem oil before, consider testing a properly diluted neem product on a small area of skin first.
You can also simplify your recipe by leaving out dyes, fragrances, dried flowers, and essential oils. If you notice irritation or discomfort after using a homemade skincare product, discontinue use.
