How to Make Bath Bombs: DIY Wedding Favors

diy bath bomb

Want to learn how to make bath bombs? Not only are bath bombs a great way to enhance an already pleasurable activity (who doesn’t love a warm soak in the tub!), they also make for fantastic shower or wedding favors.

Bath bombs smaller than these sell for  $6.45 a pop at Lush. If you take lots of baths, your money will dissolve pretty quickly.

Before I go on to tell you how to make bath bombs, I have a confession to make: this is the third bath bomb recipe that I’ve tried – and the only one that worked for me. I nearly gave up after my last attempt turned into a crumbly mess – but something in me was fiercely determined to succeed. And that I did!

After doing some heavy duty reading on how to make bath bombs, I’ve realized that perfecting a bath bomb really does take practice. You might not get it right the first time – and if that’s not okay with you, then you might want to hop on over to Lush to purchase your bath bombs, instead of making them.

If you don’t have all the ingredients to make this recipe, all you really need is baking soda, water, citric acid and essential oil. I suggest you read this guide to making bath bombs before you proceed.

If you are making bath bombs as favors, you’ll probably want to get smaller molds or just fill half the mold for each one. This recipe makes 2.5 eight ounce bath bombs.


    • 8 oz. baking soda
    • 4 oz Citric Acid
    • 4 oz. corn starch
    • 4 oz. Epsom salts
    • 3/4 tsp water
    • 2 tsp. essential oil (I used peppermint)
    • 2.5 tsp almond oil or other light oil
    • A few drops food coloring
    • sugar flower (the kind you use for decorating cakes)
    • Clear Plastic Fillable Ball Ornament

Gather your dry ingredients.

Dump all of your dry ingredients into one big bowl and stir.

Place wet ingredients in a small jar and mix.

Place sugar flower upside down in one half of the baubles.

Pack mixture tightly into first half of plastic ornament. Repeat with second half. Pile mixture loosely on top of filled second ornament and press both halves together. If you find that the mixture is not packing well, place back into the bowl and add a WEE bit of water. This is tricky, because too much water will ruin your bath bomb.

    I've always wondered how this was done! Thanks for the tutorial - looking forward to trying it!

    You're welcome Jennifer!

    Super cute. Where do you get citric acid? I want to make some too!
  4. Posted by Christina on January 10th, 2012 at 4:00pm

    You can buy citric acid at your local pharmacy. Some health food stores also sell it. The cheapest way is to buy Citric Acidonline.

    I own Black Bear Wine and Brew in Maple Ridge BC and we sell Citric Acid at a much lower cost than most other sources. All wine making places should either stock it or be able to bring it in at a very reasonable cost.

    Thanks for the great tip June!

    Where to get the mold?
  9. Posted by Christina on October 5th, 2012 at 12:53pm

    You can get them at craft stores such as Micheals.
  10. Posted by Ashley on October 26th, 2012 at 9:44am

    Why do you need the sugar flower?
  11. Posted by Sanda on November 4th, 2012 at 11:01am


    I followed the exact quantities and it is the second day now that i am waiting for them to harden.
    The bath bombs are in ice trays, nothing special about the material. I need the gift in one week.

    Can you please advise?

    Thank you :)

    Sorry to hear they didn't turn out Sandra. As I mentioned in the post, they are tricky. It took me several attempts to get it right. Try this link for more specific bath bomb info

    hey christina,
    the recipe says to use sugar flour but it doesn't specify how much....since you mix all the dry ingredients first, how much sugar flour do you use?
  14. Posted by Christina on November 9th, 2012 at 3:11pm

    Hi Felicia,

    It`s a sugar flower, not sugar flour:) It`s made of icing sugar - you use them to decorate cakes. Optional, but looks pretty.
  15. Posted by jennifer on November 28th, 2012 at 2:25pm

    Made them and they worked first time out of the gate!!!! perfect recipe I used mccormick food coloring red 2 drops for pink and it was the perfect shade!!! Christmas presents for everyoe!
  16. Posted by Christina on November 28th, 2012 at 2:30pm

    That's awesome Jennifer! I haven't tried pink yet - I bet they're pretty!
  17. Posted by Lauren on December 2nd, 2012 at 11:56pm

    Hi, this is an awesome idea and im going to make a few of these for my boyfriends mum!! i was wondering where you get the molds from!

    thanks :)
  18. Posted by Lauren on December 2nd, 2012 at 11:58pm

    sorry and adding to my last comment, what size mold did you use :)
  19. Posted by Stacy on December 20th, 2012 at 11:35pm

    I make bath bombs regularly...I love them.. My recipe is a bit different but I do want to give a little suggestion, instead of water use witch hazel in a spray bottle. It works a lot better....
  20. Posted by micki on April 5th, 2013 at 11:34am

    My bath bombs cracked when they dried. Is it because I used too much water? Also my bath water was cloudy is that normal? Thank you for your recipe
  21. Posted by Christina on April 5th, 2013 at 1:08pm

    Maybe too much water Micki. Yes, the water will be cloudy.
  22. Posted by Kayla on May 4th, 2013 at 5:48pm

    Could I replace the citric acid with lemon juice? I read I could replace each teaspoon of citric acid with 4 tbsp. lemon juice, but I want to make sure it won't affect these.
  23. Posted by Christina on May 7th, 2013 at 2:14pm

    I've never heard of using lemon juice instead of citric acid.
  24. Posted by Bindy on May 30th, 2013 at 11:48pm

    (Citric Acid can also be bought at local wine and beer brew shops.) Won't the sugar flower make the bathtub have an oily, ring around the tub? I love this idea, and am going to try it, but I don't know about the sugar flower!
  25. Posted by Christina on May 31st, 2013 at 11:43am

    Bindy, thanks for the tip.

    re: flower, no, I didn't find that the sugar flower made it oily.
  26. Posted by Zoe on June 25th, 2013 at 3:02pm

    Where do you get those cute sphere containers? I've tried Michaels craft stores. I've tried multiple bath bombs that haven't worked but I am exited to try this one!
  27. Posted by Christina on June 26th, 2013 at 9:21am

    Zoe, you can buy the plastic molds here:
  28. Posted by Tammy on August 9th, 2013 at 9:20pm

    I know this is an older post, but since it is pinned, people are still looking. With that in mind, not in the spirit of rudeness, but in the spirit of safety and education, you really need to understand that essential oils are NOT a blanket "add x amount" . These oils are NOT simply a fragrance! Every essential oil has its own maximum usage rate and that rate also varies with the product that they are being used in. Some essential oils are not to be used over 0.5% even in bar soap. Additionally, NO essential oil should be used neat, therefore people should also know to not touch the oils with their bare hands, so to use gloves when mixing into bath bombs.
    Another thing too, using food coloring is really not a good idea. Too much food coloring and you will be wearing the color. It can also stain your tub. They make many colorants that are appropriate for use in bath and body products. You will find them available in craft stores and on line from reputable soap supply vendors.
    Please do not advise people to give gifts with ingredients that could harm them or stain their friends :)
  29. Posted by Christina on August 10th, 2013 at 11:44am

    Tammy, I have been working with essential oils for 15 years - never had issues. Hopefully people will have common sense with the food coloring and won't put in more than a few drops. Yes, pigments are ideal, but they are an added expense for those who want to keep costs down.
  30. Posted by Sarah on August 23rd, 2013 at 8:13pm

    Hi, I'm allergic to almonds so can't use the almond oil. I'm not sure what is considered a light oil. Could you make a substitute recommendation? Cheers!
  31. Posted by Joanna on September 30th, 2013 at 10:44am

    Uh oh! My bath bombs melted overnight. Did I use too much water?
  32. Posted by Bianca on November 23rd, 2013 at 12:48am

    Hi there I'm wondering if this mixture could be used in silicone moulds, or ice tray type. So it's only half instead of the balls?? (Hmm would they hold)
    This recipe sounds amazing and I can't wait to try it!
    Thanks Bianca
  33. Posted by Tammy Loftin on December 3rd, 2013 at 3:27pm

    The web site for is not working do you know if they changed there site? Thanks Tammy
  34. Posted by Rebecca on February 4th, 2014 at 4:45pm

    2 teaspoons seems like ALOT of essential oil (esp since they come in bottles ranging from 0.25oz to 2oz (that's 1.5 tsp to 12 tsps!)
  35. Posted by kristina gutierrez on May 1st, 2014 at 6:40am

    Where do you buy the Sugar Flowers, or do.i have to make them? Also, instead of essential oils could skin safe fragrance oils be used as well?

    Thank You :)
  36. Posted by Christina on May 2nd, 2014 at 10:00am

    We bought them at a local Bulk Food store.
  37. Posted by Anjelica on May 12th, 2014 at 1:16pm


    I have read over this recipe many times, and am planning on trying it. I have a question about the sugar flower. Do you know how it is made? like is it fondant, buttercream frosting? or is it royal icing (this is the one that hardens)

    I'm wondering because i also decorate cakes so I was thinking i could save a step and make the flowers myself! but I want to make sure that would be okay in the bombs. Thanks!
  38. Posted by Heather on June 21st, 2014 at 3:36pm

    Thank you for the tutorial. I am inspired to make these for a friends gender reveal baby shower we have coming up. Thinking of putting them in a colored bag (non see through) for the reveal. It is a thought. But your pictures and descriptions are very easy to follow. Thank you!
  39. Posted by Patty Everett on July 23rd, 2014 at 10:52am

    I've wondered how far in advance you could make these-- do they keep well?
  40. Posted by Linda from Ohio on November 10th, 2014 at 11:06pm

    I can't wait to make these, thank you so much for taking the time and trouble to make step by step instructions I really appreciate that. Just a quick question, what brand of Epsom salts do I use, as I've read that some brands aren't all that fine in texture to create bombs? Again thank you!!
  41. Posted by DavetteB on November 15th, 2014 at 10:09am

    To the other poster's comment about essential oils: even though she is using a lot, this recipe is making more than one bath bomb, and most tubs hold about 20 gallons at half full, giving you your dilution.
    I would be careful with peppermint since it can get quite "tingly" in the southern hemisphere, KWIM? If you are making smaller bombs with this recipe, it will cut the amount even more.
    As for gloves, it may be nicer since you are making them as gifts vs. personal use, but I say that for sanitary reasons more so than worrying about the oils. Skin is a slow absorption method and I'm sure you or anyone else is going to wash their hands after.
    And finally, the water is going to be cloudy and oily from the cornstarch and oil, not the sugar flour. HTH
  42. Posted by Erika on February 11th, 2015 at 4:52pm

    Is it possible to just buy epsom salt that's already scented instead of using the oil?
