There’s something incredibly relaxing about a warm bath, and this homemade bath bomb recipe makes it even better! There are thousands of bath bomb options available, but it’s easy to make your own with natural ingredients. Kids and adults alike love them and they make a great gift.

While they can cost up to $9 each to buy, you can make a whole batch for just a few dollars!

DIY Bath Bomb Recipe

When I was younger, I loved bath bombs. I’ve avoided them as I’ve gotten older though because store-bought versions often use artificial ingredients, dyes, and fragrances. For a while, I just used bath salts in my bath water when I wanted to unwind, but I missed having a bath bomb.

These homemade bath fizzies are a great solution! They’re made with nourishing sea salt or Epsom salts, alkalizing baking soda, and fizzing citric acid with a nourishing oil base. I’ll add different essential oils or even dried herbs depending on my mood. Peppermint, eucalyptus, or lavender essential oils are a few ideas.

If you need a gift idea for an Easter basket, Mother’s Day, Christmas, or even a birthday, then DIY bath bombs are a great option.

How to Make a Natural Bath Bomb Recipe

Bath bombs only take seconds to make, so it’s important to have the ingredients on hand and measured before you start. Once the water hits the citric acid they start to fizz and you’ll need to work fast. Most of the ingredients are pantry staples in many homes, but make sure you have these on hand:

Baking Soda

The backbone of this recipe is alkalizing baking soda. It complements the acidic citric acid and helps with the fizzing reaction. It’s a frequent ingredient in my detox baths and can even help soothe sunburn.

Citric Acid

You might not have citric acid sitting on your pantry shelf, but you’ll need it for this recipe. Citric acid is what gives us the fizzing reaction that makes bath bombs feel like bathing in champagne.

Corn Starch or Arrowroot

Corn starch provides the silky feel that we all love from bath bombs. I usually use organic cornstarch in this recipe (and my natural deodorant). Arrowroot also works but doesn’t provide quite as silky of a finished product.

Liquid Ingredients

These are all very versatile and you can pick any combination you have on hand. You’ll need some kind of:

  • Oil: Pick a simple oil like olive oil, almond oil, or coconut oil. If you’re feeling fancy use sea buckthorn, argan, or apricot oil. You could also create your own blend with several different oils.
  • Salt: Stick to basic sea salt or kick it up a notch with Epsom salt or your favorite salt for this bath bomb recipe.
  • Liquid: Basic water will work, but I also love using organic witch hazel for some extra skin-soothing. Some people find that the bath bombs stick together better with witch hazel.

Scents and Colors

There are so many options here. Use your favorite essential oils, add dried herbs and flowers, or make them scent-free. Some options include:

  • Lavender and Vanilla or Rose and Ylang-Ylang… or just use your imagination!
  • Kids love the fizzy action of bath bombs! I’m pretty cautious with essential oils around young kids so I use kid-safe blends when making them as gifts for my kids.
  • You can even add some natural food coloring to change the color.

The Best Essential Oils for Bath Bombs

While there are a lot of different oils that smell good, not every essential oil is the best option here. Some essential oils are more irritating to… ahem… sensitive tissues. Oils like cinnamon, clove, ginger, and lemongrass are more prone to irritating skin.

The recipe below uses a .5% dilution of essential oils (that’s 1/2 percent, NOT 5 percent), which shouldn’t cause problems for most people. And of course, if you tend to be more sensitive, then dried herbs are a gentler option. Here are some gentle, skin-friendly essential oils that also smell great!

Herbs for Bath Bombs

If you want to add some skin-soothing herbs or dried flowers here are some options. Keep in mind that if the pieces are too large, the bath bombs won’t hold together, so I wouldn’t mix in whole leaves or flowers. These herbs are generally safe, especially in such low amounts, but do your research to see which ones will work for you.

DIY Bath Bomb Tutorial

Making a homemade bath bomb recipe is a great project for kids to help with. Some DIY beauty recipes (especially homemade soap) require precise measuring and handling harsh chemicals like lye, so they aren’t great to make with children around. These bath bombs are the opposite and make for a fun project to do with kids. They’re simple to make with kid-safe ingredients and are completely versatile. Let the kids think of ways to mix up the scents, colors, and other fun customizations.

Bath bombs are a great way to relax in the tub after a long day of dealing with kids, cooking, and all the other activities that motherhood entails. If you’ve never tried them, I highly encourage it. It’s one of my favorite things to do at the end of the day.

  • In a large mixing bowl, combine all of the dry ingredients (baking soda, citric acid, corn startch, and sea salt) and stir well.
  • In a small bowl combine the carrier oil, vanilla extract, essential oils, and natural dye if using.
  • Slowly add the wet ingredients to the dry mixture and work it together with your hands until its crumbly.
  • Add in the dried flowers or herbs if using.
  • Spritz the witch hazel or water onto the bath bomb mixture, mixing well with your hands to combine. Do this just until the mixture holds together when squeezed without crumbling. It should feel like wet sand. You may need to add slightly more witch hazel if it hasn't achieved this consistency yet.
  • Firmly press the bath bomb mixture into silicone molds, muffin tins, ice cube trays, or bath bomb molds.
  • Gently turn the molds over onto a flat surface to remove the bath bombs and allow to dry for 48 hours, or until hardened.


  • Storage: Keep the bath bombs in an airtight container away from moisture.
  • Shelf Life: About 6 months. 

Non-Toxic Pre-Made Bath Bombs

I finally found some natural bath bombs that use a similar recipe to mine. These are gorgeous and use only natural ingredients. They’re also much bigger than most bath bombs and last longer in a bath. I’ve been sending them as gifts lately and my friends are loving them too!

Bath Bomb Troubleshooting

Although this recipe is easy and doesn’t have a ton of ingredients, they can be a little tricky to make sometimes. The key is to add the right amount of liquid and work quickly when molding.

  • Bath bomb sticks to mold: You may have used too much liquid or didn’t remove them from the mold quickly enough.
  • Bath bombs fall apart: Either too much or too little liquid or they may have been left in the mold too long.
  • Bath bombs cracking when dry: too much moisture in the mix or humidity in the air.
  • Bath bombs sink in the tub: too much moisture or humidity or they haven’t dried long enough.
  • Bath bombs don’t fizz enough: They might not have had enough time to harden, or they weren’t wrapped before storage and they had a reaction with the air.

    Thank you sooo much for all the detail and this super easy recipe. My whole family had a ton of fun making it. My daughter had an Entrepreneurs Day at school and we made these to sell. She was pretty much sold out! Kids absolutely loved bathing with these.
    We used rose scented oil which is actually food grade and ylang ylang essential oil. It smelled phenomenal! We added tiny dried rose buds and fresh lavender flowers to our bath bombs too. They looked superb!
    I agree that it doesn’t last long if you’ve got kids in the house, they love bathing with them all the time!!!

    Mine forms beautiful and then a few minutes while drying, they started to expand. And hour later, flattened out and I have a flat mess. I followed instructions to a tee. I don’t know what I did.

    Thanks for sharing this recipe! I just made my first batch after looking for a recipe that included epsom salt. Excited to find another item that I can replace with a natural, homemade alternative!

    What’s the best way to dry them? Fridge? Warm place? Thanks! ?

    How many bombs will the above recipe make (approximately)? Thanks!

    What’s the consensus on the drying process? Take them out of the tins immediately to dry on parchment paper, or something else? Or leave them in the tins for 24-48 hours?

    Hello! Would all of these ingredients be kid safe? I would like to make some for my children. Thank you!

    If you are like me and don’t have any citric acid at home, I found a perfect natural substitute. 1 teaspoon of citric acid is equal to 4 tablespoons of lemon juice. I hoped this helped you!

    Hey thanks for the post- you are awesome!
    Can you explain more about the mix of liquid? Why do you add water to oil?
    Can I do this without water at all so it will last longer?

    Hi – these bath bombs came out great in the silicone molds. But they stick to the metal bath bomb molds. Should the molds be oiled? You say to oil conventional molds, but not bath bomb molds, so I haven’t, and they stick. Thanks!

    I love your bath bomb and shower melt recipes! I read on the bath bomb one that they need to be used within 2 weeks. I want to make some as gifts and was wondering if there’s a safe way of making them last longer? Thanks!
