how to: make homemade bath bombs.

I like a good bath. It’s the best way for me to unwind, escape the dishes, catch up on a little pop culture in the way of an US Weekly or a thick People Magazine, and deal with my ongoing pain. I’ve written about how to make homemade bath salts, and how to make homemade sugar scrub, and today I’m going to show you how to make homemade bath bombs. They’re the bomb.

Ha ha, I slay myself.

Bath bombs are little balls of fizz that dissolve in hot water and add a little scent, moisture, and effervescence to your bath time. Doesn’t get any better. Plus, they’re so easy to make at home.

Here’s what you need:

-Cornstarch 1/2 cup
-Epsom Salt 1/4 cup
-Baking Soda 1 cup
-Citric Acid 1/2 cup
-3/4 tablespoon water
-Essential Oil {optional}
-Olive Oil 2 3/4 tablespoons
{optional, but you know I love me some Olive Oil}

Finding the Citric Acid was the hardest part of this project. I ended up buying some from my local pharmacy, but I’ve read that you can buy Citric Acid at Whole Foods or any other natural, granola type store {the kind my parents keep in business}.

You’ll also need something to shape the bath bombs. I used my cookie scoop, but half a plastic Easter egg would be perfect to use. I’ve seen bath bombs in the shape of small muffin tins or candy molds as well, so use whatever you have on hand instead of buying supplies.

Ahead of time I ground up the Epsom Salt until it was a really fine powder. You don’t want chunks of salt in your bath bombs, that’s just tacky.

Mix together your dry ingredients. If you want to get really fancy and sift them, it will work even better.

Now get out a separate bowl to mix up your wet ingredients. You can’t mix them into the dry mix yet or everything will start bubbling and fizzing. We don’t want that.

I decided at the last minute to add essential oils, just to give my bath a little kick. I need all the energy I can get so I picked the Laundry Tree essential oil ‘Energy’. I’ll let you know how that pans out.

Measure your essential oil into the liquids. I chose not to add coloring, but this is where you’d do it if you were so inclined.

Now pour the liquid into the dry ingredient
s. You have to work fast at this point because it’s about to get bubbly.

See what I mean? Hurry, get stirring!

Whisk it all together until you get a mix the consistency of wet sand.

Like so.

Now it’s time to mold your bath bombs.

Scoop it up, pack the mixture in really tight and turn upside down on a cookie sheet or plate to dry. You might have to tap the back side to get it to come out in one piece.

And if you get one that doesn’t come out in one piece, don’t stress. Just plop it back into the bowl and re-shape it. This one was particularly ornery and had to be re-shaped a few times. Stinker.

And there you go, beautiful bath bombs. Let them dry overnight before you try to transport them anywhere or they’ll fall apart.

If you’re giving them as gifts put them in a clear cellophane bag tied with a beautiful ribbon and a gift tag. I think they’d be a great gift for guests at a bridal shower don’t you?

    I have been looking for a tutorial on Bath Bombs! Thank you so much! They look so much easier than I thought.

  8. oh amanda :

    Fun and SUPER cute!

  9. Kathleen :

    Thanks for sharing. I make bath salts for gifts but hadn't considered bombs–I thought they were more difficult to make. Thanks for proving me wrong.

    I could see packing these in those little cupcake wrappers for safekeeping.

  10. Elizabeth :

    Thank you for sharing a great, easy to follow "recipe". I have been wanting to make these for months and will be gathering my supplies today. Thanks again for sharing a simple, inexpensive GREAT idea. Much appreciated!

  11. Julie :

    I cannot wait to make these.

  13. Rachel@MyPinkFlipFlops :

    You make it sound so easy! Yea!

  14. sillygirltree :

    hello! bookmarked! I have begun to use bathsalts/bath bombs almost daily and have been searching for a way to make it more affordable than buying commercially available product.

    Thanks a million!

  15. Cammi at Simply Stunning Ideas :

    awesome idea! I'm bookmarking this for future use!

  16. Lynn :

    Okay, this is a great idea for mother's day, things my granddaughters and I can do for their mom…and maybe I'll just sneak a few "bites" out myself!

  17. Ginger Devotion :

    I was thinking that maybe if you spray the inside of the scoop with cooking spray they wouldn't stick to it.

  18. Lady Phoenix :

    Wow – that does look easy! Sounds like a great end-of-the year teacher gift project for me.

    About how much did you spend on all the ingredients? I'd like to know so I can eyeball a price per bomb & get an idea of how much I'll need when I go shopping for those ingredients.

    First time-visitor, but won't be the last! :)

  19. Lady Phoenix :

    Oh, and I forgot to ask: do you think crushing Vitamin C tablets would work as a substitute for the Citric Acid?

  20. Shawna :

    your site is AMAZING!! I just recently began making bath salts and sugar scrubs and next on my list was to try bath bombs. They are so cute and fun!! & luckily the citric acid was very easy for me to come by since i work in a pharmacy.. + i can use my employee discount when purchasing it!! That will really help me because i never realized that this stuff would all be so expensive! I just think im doing way too much at one time. :D Thanks again!!

  21. Michele Hays :

    FYI: Citric Acid has several culinary uses (it’s the “sour” ingredient in most sour candy, some people use it to sour borscht, and it’s used to acidify low-acid foods when canning) It’s often called Sour Salt or Citric Salt: you might find it in the Eastern European or Middle Eastern foods aisle or the canning/preserving aisle in a natural or ethnic grocery store
