Bath bombs have become a hugely popular product to brighten at-home self care. They make bath time fun for kids and relaxing for adults. This DIY Bath Bomb recipe allows you to enjoy the luxury at home without the expensive price tag.

Most of the ingredients in bath bombs can be found in your kitchen already. If not, they are ingredients that you should stock up on because they can be used in MANY other recipes and applications around the house.

Dry Ingredients

Corn Starch: Corn starch is found in the baking aisle.

Citric Acid: Citric acid is a natural ingredient made from citrus fruit. This, mixed with the baking soda, is what makes the bath bomb fizz.

Epsom Salt: Epsom salt is the common name for magnesium sulfate. You can find it online or in the pharmacy section of your grocery store. It is wonderful as a soak for sore muscles.

Baking Soda: Baking soda can be found in the baking section of your grocery store. I prefer to buy it in bulk because it has so many uses around the house from cleaning your garbage disposal, eliminating odors, and even in cleaning laundry. It also helps make the bath bombs nice and fizzy.

Mica Powder: Mica powder is a natural soap colorant that is safe for use in bath bombs. We do want to use the least amount possible, though, to obtain the color you want in your bath bombs. It is also completely optional in this recipe. Also, feel free to use any color you like.

Dried Orange Peel: To make dried orange peel, zest three oranges and allow the zest to dry, in a single layer, at room temperature for two days. You can also find it in the spice section of your grocery store.

Wet Ingredients

Essential Oils: Essential oils are optional in the bath bombs, but they add a lovely scent to your bath. Feel free to skip them if you are sensitive to fragrances or make sure that you use an oil that is safe for use on the skin. I have chosen to use Orange essential oil in this recipe, but you can use any oil you wish. Lavender or Tea Tree oil would be wonderful.

Coconut Oil: Coconut Oil is the liquid that will hold the bath bombs together. Warm it so that it is a liquid. You can also use Almond oil.

Water: Feel free to use regular tap water.

How to Make DIY Bath Bombs

Measure out all of your ingredients. Choose what color mica powder you would like to add to your bath bombs (if any), which essential oils you would like, and if you want to add any dried ingredients such as orange peel or dried lavender.

Slowly pour the oil mixture into the dry mixture as not to make it fizz too much. Stir and mash together until completely incorporated and the mixture looks like wet sand.

Press the bath bomb mixture into the two mold halves, generously packing it in there. Twist the two halves together to close, and allow to dry for at least 24 hours.

To remove your bath bombs from the molds, tap on the outside of the mold and twist to separate.

Store the bath bombs in an airtight container for up to six months. You can also wrap them in plastic wrap. If you want to get really fancy, you can use shrink wrap sleeves to wrap your bath bombs. Heat them with a blow dryer or heat gun to shrink the wrap around your homemade bath bombs.

Notes

Feel free to play with essential oils and mica powder to customize different looks and scents. Lavender essential oil and dried lavender would make a great, calming bath bomb.

For an added treat, you can even press a toy into the middle of the bath bomb before pressing the two halves together. The toy will be revealed when the bath bomb dissolves in water.

    • Hi, LeeAnn. It does color the water a little bit, but not as much as color tablets. You can always add more mica powder to make the color a little stronger. I think it is a great replacement, though, as kiddos will have fun watching the fizzing. 🙂

  1. Hi. Is the water necessary? And is the alcohol necessary? I only found 70% alcohol.
    I’ve seen a recipe for 1Tsp of water for the same amount of dry ingredients. Why does it differ? I’m concerned because my bath bombs have been hit or miss and I don’t know why.

    Thank you.

      • Hi, Amber. I chose to use water in this recipe rather than alcohol. You can absolutely use Isopropyl alcohol in place of the water. I found that if the water is added slowly, it doesn’t activate the bubbling and it’s an ingredients more readily available for most people.

    • Hi, Larry. I’m sorry for the late response. Yes, you can use liquid coconut oil in this recipe. The dry ingredients will absorb the oil and it won’t affect the finished bath bomb.

  2. Hey! Is it necessary to add water? I’ve tried this and when I added water the mixture just kept expanding and would ruin the whole thing.

  3. when you put this in the bath, is it a strong enough smell that it marinates in the room. do you also smell like that when you leave the bath

    • Hi, Taylor. This bath bomb is very subtle. It contains dried orange zest and a bit of orange essential oil. So, no it won’t permeate the room and you won’t notice a strong lingering smell.

    • Hi, Mehar. You can use food coloring in very small quantities. I would use 1-2 drops at a time and keep the color fairly light. You don’t want to use too much that it will stain skin or the bathtub.

  4. Hi! I am hoping to make this with my students so I am trying to budget and plan ahead. Can you tell me approximately how many this recipe makes?
