DIY bath bombs are an easy project that you can make without any prior experience. The ingredients you’ll need are available at many health food stores and pharmacies. You can also order them online, and I’ve left links to where you can find them. Expect this recipe to take you about an hour or less to make. After that, the herbal bath bombs need a day to dry and harden. After that, store them in an airtight container and add them to your warm bath for all-natural indulgent relaxation.

Bath Bombs with Herbal Essential Oils

The three herbal essential oils I chose for this recipe have benefits for both the mind and your skin. Lavender essential oil is soothing and gentle and smells intensely floral. Peppermint has that natural zingy menthol that will make your skin tingle pleasantly. Marjoram is a sweet herb related to oregano and its oil is calming and sweetly herbal.

When you make this herbal bath bomb recipe, you blend the essential oils into a base that fizzes in contact with water. That base also has a quarter cup Epsom salts that will nourish you from the outside with its magnesium content. All in all, these are wonderfully indulgent yet therapeutic natural bath bombs that the whole family will love.

Tools for Making Bath Bombs

You don’t need much to make bath bombs but you will need a spray bottle to moisten the bath bomb mix. You’ll also need molds to hold the mixture together while it hardens. Though two-piece bath bomb molds are suitable, to make this herbal bath bomb recipe I used a silicone mini-muffin mold.

Scatter a light sprinkling of dried herbs in the mold cavities

Make Bath Bombs in Silicone Molds

I’ve created this recipe to be both natural and very easy to make. The trouble with making bath bombs is getting them the right consistency — too dry and they won’t hold form and too wet and they get stuck in the mold. That’s why I advise using a silicone mini muffin tray to make this herbal bath bomb recipe. They’ll pop out easily and make creating bath bombs stress-free. You can use two-piece bath bomb molds for this recipe too but they’re a lot more tricky to master.

Pour the liquid ingredients into the dry ingredients

Make the Bath Bomb Mixture

  1. In preparation, decorate the bottoms of each cavity of the mold with a scattering of dried herbs and flowers. These will be visible on the tops of your herbal bath bombs.
  2. Place the baking soda, citric acid, and Epsom salts in a bowl and whisk together.
  3. Pour in the liquid oil and essential oils and blend together with a whisk or your hand
  4. Spray the mixture with a couple of pumps of witch hazel and stir. Continue spraying and stirring until the mixture is the right consistency.
  5. The consistency should be like lightly damp sand. Not too wet but just enough to hold form when you squeeze it together in your hand. If the mixture easily crumbles, add another spritz of witch hazel, mix, and try again.
  6. Once the bath bomb mixture holds form easily you’ll need to work quickly and follow the next steps.

Make Herbal Bath Bombs

The next part is all about artistry and you can customize it however you’d like. The first bits of dried herbs and flowers should already be in the mold cavities. You did that before making the bath bomb mixture. This is what you do next:

  1. Spoon about a Tablespoon of your bath bomb mixture into each cavity. You’re aiming to only fill the cavity halfway. Press down slightly.
  2. With your fingers, scatter a layer of dried peppermint on top, especially around the edges. This will create a pencil line along the sides of the herbal bath bombs.
  3. Spoon another Tablespoon of the fizzy mixture on top and then press the whole thing down with your fingers. Press as hard as you’d like without leaving finger marks.
  4. If the mixture starts fizzing at all that means it’s a little too wet. You can press it down with the back of a spoon but it may need this done several times before it sticks and stays.
  5. Decorate the bottoms with more peppermint leaves if you’d like
  6. Now leave it to harden for 24 hours.

Your Natural Bath Bombs are ready to use

After you’ve waited that day, you can safely pop the herbal bath bombs out of the mold. Store them in a water-tight container or use them right away — it’s up to you. To use them, simply pop one or two into a hot bath and watch them fizz away. As they disintegrate, they’ll fill your bath with tiny pieces of herbs, a sweet fragrance, and a small amount of conditioning oil. Once you’ve soaked up the indulgence, all will drain away but you may need to rinse the bath with water to move some of the herbal pieces along.

This herbal bath bomb recipe looks professional, smells incredible, and makes pretty handmade gifts. Use or gift them within one year of making them since after that the scent and color will fade. While you can use and gift them on their own, I’ve created the recipe to match this herb garden soap recipe so that you can make both and pair them in pretty gift sets.

  1. Hi Tanya,
    I share your love of nature and your ethos to keeping everything natural and growing your own food and body care. Very grateful for the time and effort to share your knowledge and wisdom.?❤️
    Have made these bath bombs first time using a 1/4 cup measuring cup to form them as I don’t have a mini muffin tin. I got 4 bath bombs out of it holding together nicely but am finding after 15 hours at room temperature they are slowly fizzing on the outside a bit. They seemed fine when I initially made them. Any ideas how to keep them dry without fizzing before use?

    1. Hi Nelia and this is a common issue with beginner bath bomb making — one I’ve made myself a few times! It’s probably because you used too much liquid (witch hazel and/or water) in the recipe. If you’re sure it couldn’t be that, then it could also be that the room is very humid.

    I just found you and your web-site. I LOVE! everything you are doing as it is all organic, and free of synthetics. I have ordered everything to get started on making my first tray of the lavender, peppermint and calendula soap. My question: can I infuse natural incense cones (I have jasmine, rose, orchid and lavender) to achieve a color for soap or bombs? Are they safe to use in soaps or bombs?
    thank you,
    Shirley

    1. Hi Shirley and lovely to hear from you :) I wouldn’t advise using incense cones for anything than what they’re intended for. Even if they are made with essential oils, you don’t know what else is in the cones or if the essential oil used is suitable for skin. Not all essential oils are the same! Stick with using pure essential oils from trusted suppliers. Each oil should have an IFRA document listing whether it’s suitable for use in various types of skincare and products. Good luck and have fun!

  3. Hello. Do you happen to sell the ingredients needed to make the bath bombs? I would love to make that purchase. If not, where did you get your ingredients from?

    1. There should be links within the recipe to help, Najla. I don’t sell the ingredients direct though.

  4. WI enjoy making bath bombs so I will try this way.
