Learn how to DIY Bath Bombs easy with this step-by-step tutorial. You’ll be enjoying a relaxing bath in no time!
Though I don’t do it nearly often enough, one of my favorite ways to decompress after a long week (or sometimes a long day) is to pour a glass of wine, light some candles, and hop into the tub. To make the experience even more special, I toss one of these DIY bath bombs into the water. The fizzy bubbles, essentials oils, and beneficial minerals are a treat for the senses.
Today, I’m going to show you how you can create your own custom DIY Bath Bombs at home. If you’re anything like me, maybe having these on hand will encourage you to decompress a bit more frequently.

In an effort to bring some relaxation into my home and create a spa-like experience whenever I needed it, I decided to make my own DIY Bath Bombs.
Now, if you’re feeling intimidated by this process, don’t be. These bath bombs are so simple to make and really easy to customize. Let me show you.
First, gather all of your ingredients. I found everything online and linked things up below to make it easy for you. (This post contains affiliate links.)
How Do you Make DIY Bath Bombs?
Begin by measuring out and whisking together your dry ingredients in a large bowl. I used a coloring pigment for my diy bath bombs. Since it’s a dry pigment, you’ll want to include that in this step. Add as little or as much as you’d like to achieve the color you prefer.
Next, in a small cup, mix together the wet ingredients. This is also where you’ll add the essential oils. You can get essential oils almost anywhere these days. I recommend shopping for these in person so you can find a scent you like. My favorite oils come from Young Living.
Also, pay attention to the benefit each oil offers. I made three different varieties. The purple bath bomb has an oil for stress relief, the blue prompts sleep, and the yellow promotes joy.
The next step is very important. You need to add the wet ingredients to the dry ingredients. You’ll want to do this very slowly, adding little drops at a time while mixing.
The citric acid is what causes the bath bombs to fizz when it comes into contact with water. Adding the wet ingredients slowly minimizes this affect, allowing you to create the ball.
Once mixed, you’re ready to mold. I picked up these bath bomb molds to create a ball shape. However, you can use things like a cupcake pan or silicon mold to achieve different shapes and sizes.
For this round mold, fill each half, packing it in slightly until it’s overflowing. Then, firmly press the halves together. Let the mold sit for one minute. Once set, tap the mold and pull it apart.
You’ll want to let the bath bombs dry for at least 24 hours before you create your own mini spa in your tub.
It’s that easy!
DIY Bath Bombs
Makes 4
Here's what you will need:
1 cup baking soda
1/2 cup citric acid
1/2 cup epsom salt
1/2 cup cornstarch
Coloring pigment, optional
2 1/2 tablespoons almond oil (or melted coconut oil)
3/4 tablespoon water
12-15 drops essential oil
Bath bomb molds
In a medium bowl, mix together all of the dry ingredients. Add as much or as little color pigment to achieve desired look. Whisk to combine.
In a separate small bowl, mix together the wet ingredients.
Add the wet ingredients to the dry ones very slowly. (This is very important; otherwise you will activate the citric acid which is used to create the fizzing affect.) Mix until combined, and the ingredients look like wet sand.
Fill each half of the mold, packing the mixture in slightly until it's overflowing. Press the halves together firmly. Let the filled mold sit for one minute. Lightly tap the mold and gently pull it apart to remove the bath bomb. Let the bath bombs dry for 24 hours before enjoying in the tub.

If you have yet to make or even experience a bath bomb, I definitely recommend giving it a try.
What I really love about making these DIY bath bombs at home is that you can customize the oils and colors to create the best experience for you. Whether you want to relax, sleep more easily, or feel inspired, just changing a few things will help you achieve the mood you’re after.
These DIY bath bombs also make a great gift. Wrap up a few with a bottle of wine and a couple candles for the ultimate treat.
My boyfriend and I made some bath bombs when I was at his this summer. We tried one and we loved it. It’s really easy to make, and really not expensive. And I agree with you: it makes a wonderful gift.

So cute! I love baths and I had no idea these were so easy to make. I’ll definitely try this out for myself and as gifts. Thanks Michael!
Where do I find the dry color pigment ingredients?
There’s a link to the pigments I used in the post above.

Hi there–I can’t get the link for pigments to work on either my old Chrome laptop or my brand new Edge one. Could you please just name the exact pigment you use here with enough details I can find it–brand, type, size, etc? Not sure why neither computer can get to it. It just says: “Sorry, we couldn’t find that page (with a dog illustration). Try searching or go to Amazon’s home page”. Thanks very much–I want to get the right kind the first time as yours are so nice & just what I want! Thanks!
Hi Barb! Thanks so much for bringing this to my attention. It looks like Amazon no longer sells the specific ones I used. However, I did find a substitution. (Basically the same thing just a different brand / seller.) The link above has been updated.
xo Michael
How many bombs does this recipe make? Thanks
I could totally imagine a bath bomb inspired by Carnivals Kiss on the Lips or Miami Vice cocktail. I’ll have to try your recipe with the tips from the tutorial at https://gospaces.com/blog/how-to-make-bath-bombs to make something special. Great post!
Does this recipe make the bath water turn the color of the pigment, or does it just make the bath bomb a pretty color?
Hey there! Yes, it will change the color of the bath water. The intensity of the color will depend on how much pigment you put into the mix.
xo Michael
Great post, ? This is definitely one I’ll be trying this week. I love bath bombs but never thought I could make my own ones. I usually just buy but this has inspired me to get cracking!
The best part about making them is that you can customize them to your liking. Have fun crafting!
xo Michael
Hi, thank you for the bath bomb recipe. I’m a little confused by the “3/4 tablespoon” of water measurement. Will you please clarify? Thanks!
The recipe is very sensitive to water. Too much will make the ingredients activate and your bombs won’t sent. So only use 3/4ths of a tablespoon. How that helps.
xo Michael
Hi, You probably long ago got your own answer to this, but in case you never did and it’s stopping you from making these–there are 3 teaspoons in 1 tablespoon. One-fourth of 3 tsp. is 3/4 of a teaspoon. So, 3/4 of a tablespoon (equaling 3 teaspoons) is 2 1/4 teaspoons. You could do two tsp. + one 1/4 tsp. I had to stop and figure too.
I’d love to make these for Christmas gifts and maybe one or two for myself. Having never used one, do they need to be used in a certain amount of time, or are they good for a long time? Do they need to be wrapped or can I leave them sitting out?
Great questions! I would try to use them within a year. I have mine sitting out because they are pretty, but realize that the scent may dissipate overtime. It’s probably best to store them in a contain with a lid. Hope that helps! 🙂
xo Michael
They’re good for about 6 months. But remember as all ingredients have expiration dates, it’s best to keep them in air tight bags to prevent them from losing the fizz. 🙂
Would it work to use liquid food colouring instead of the dry colouring pigment?
I haven’t tried it with liquid food coloring. You could try, but I can’t guarantee any specific results.
xo Michael
I did…..didnt mix well at all
For the recipe provided, how many bath bombs of your size mold, will this yield?
Hey, to Whitney above! For some reason the page won’t let me reply to you directly, but I wanted to let you know that I’ve tried food coloring in a similar recipe and it worked out just fine. If you know you want it lighter in color, just keep an eye on how many drops you’re using, because 1) you’ll need to mix it in like crazy to see how bright the color ends up being, and 2) it’s likely going to be a more intense shade more quickly than with powder pigments.
Also, keep in mind that most food coloring is water-based, so don’t add all of it in one spot without whisking it quickly. Otherwise, you’ll end up with a lot of foaming in that area, because chemistry!
We used liquid food coloring & added it to the epsom salts before mixing them into the rest of the dry mix. It worked great and we ended up with a soft colored bath bomb. It was much easier than trying to mix it directly into the entire dry mixture. I had looked at soap dye but found that it was basically food coloring so why buy something else, right?
What size mold did you use to yield 4 bath bombs?
Thank you very much, Michael – your beautiful photos and enthusiasm is really inspirational for me.
I have (and use) bath salts and sugar scrubs and have ALWAYS wanted to make bath bombs. I buy them occassionally at Lush (love me some Lush!) but they’re so expensive!
I am excited to give this a try, thanks again.
Does the oil in these make a greasy film at the waterline on the tub or when draining out? HATE scrubbing bath oils off the tub! Thanks!
Not that I really noticed. There’s such a small amount in each ball there might be a tiny bit, but nothing bothersome.
xo Michael
what is a pigment?
It’s what gives the bath bombs their color.
xo Michael
will thefoodcoloring stain the tub?
I’ve had no issues with staining. If you’re worried, just use a very small amount for a hint of color.
xo Michael
Amazing post. Loved it 🙂 Surely gonna try it in the weekend!
Where did you get the bomb molds???
Hi there! You can click on the word “bath bomb” in the recipe. It’s a link to the source.
xo Michael
Hi. I molded them in clear plastic molds. Took them out and laid them to dry. They started to sink down and crumble after a couple hours. Any tip?
That typically means you used to much liquid.
xo Michael
Don’t add any water. Substitute water in recipe with additional oil. It will prevent bath bomb from crumbling. And make sure to leave the bathbomb to dry in the mold for 24 hrs before removing it
Where did you get the bathtub holder at?
It was from a store called Fishs Eddy in New York City.
xo Michael
i made the bath bombs for the first time and am having trouble getting them out of the mold. Should i have used a little bit of coconut oil to season the molds first?
Hmmm. I didn’t. Tapping them very lightly on the counter worked for me.
xo Michael
I had the same issue! I also had issues with the bath bomb splitting in the middle when trying to get them out. But then I took them out and sprayed a little more water and now they are indenting and not drying right- so added too much water. What’s the trick?! I was fighting my bath bombs….
How many estimated bath bombs can be made for all the ingredients you linked in amazon?
Can I use avocado oil in place of the almond oil?
I’m not sure. I recommend the almond oil.
xo Michael
I used coconut oil, the solid sort. The mixture felt like wet sand & even mixing by hand & using food coloring, 2 drops for half a batch, my hands weren’t stained. Finding pigments at a last moments notice – not in this area. I wonder in colored chalk…yet the chalk…. well best for me to follow FOLLOW directions, I can lead myself astray! This IS easy, heck it didn’t take long. UNLESS you have a fan on blowing cornstarch, I made a fun mess…..Thank you for your ideas & I will be around for more!
Hi! I made 8 smaller bath bombs yesterday, running around town like a freak in search of citric acid. I thought it was some scientific additive, ha ha! Anyhow although I used a different recipe which lacked the Epsom salts & switched pigments for food coloring, we shall see. I also purchased a silicone mold for ice in shape of citrus wedgies, so that batch was a lemony euc. I made purple for the lavender & cannot wait to try! I saw above that the citric makes bubbly foamies so maybe I’ll package some for my grandies! Hmm ….thinking that those lemony ones would be perfect for the flea ridden fur-kid! I love it! thank you.
You can use any oil you choose, but with avocado oil which has a stronger scent, you may want to add more essential oil to overpower the smell of the oil….unless you prefer the avocado scent 🙂
Nice!
Hello! How many bath bombs does one batch make and can I use food coloring drops instead of pigment?
I would advise to use the pigment as the drops will add extra liquid which will affect the recipe.
xo Michael
Instead of using water which will cause premature fizzing, only use the oil mixture. You can add a bit more oil to make mixture consistency of wet sand. Also, if you leave bath bomb in its mold to dry for 24 hrs, it will help keep it hard for longer. I’ve noticed when using water in mixture, bath bomb tends to crumble more easily
Hi, just wanted to double check that if we use coconut oil, it doesn’t have to be fractionated coconut oil, just normal coconut oil melted? Thanks!
How many bombs does this make? I only have two bombs molds at home and I do not want to waste the ingredients. Thanks!
I forget the exact number, however you just use the mold to form them. So you can make many with one mold.
xo Michael
Hi Michael,
Your bath bombs are so cute and super pretty! I’m excited to try out this recipe. Also I just HAD to mention you on my blog http://www.thebeautyinfoprovider.com . Drop by soon? See you!
Just wondering how many this recipe yields? I am wanting to make them for Christmas but don’t know how much ingredients I need for the amount I want to do.
None of the other bath bomb recipes worked that I tried, and then I did this one, and it worked so well! Very nice bath bombs. I made 6 of them with this mixture.
This is a good recipe. USE IT!!
Your bath bomb recipe worked great! Made some with my 7 year old for her science fair project. (Best science fair project I have done – at least the best smelling one!)
Thanks for the links to amazon as well!
These look sooo pretty! Makes me wonder if you ground up your epsom salt before adding it. I’ve seen other recipes that look very textured and rough while your bombs look so smooth and effortless. ❤️❤️❤️
Thanks for sharing this! I want to get all of the supplies and make these immediately! They look like lots of fun to make with the added benefit of destressing!
I just discovered your blog a few months ago. My daughter and I made these bath bombs for Christmas presents & they were a big hit. We used green food coloring & peppermint oil and pressed into a baking pan with shapes of Christmas trees, stars, & snowmen. They turned out really cute! Thank you for the recipe and tips:)
I’m wondering if this is ok to use in a jacuzzi tub.
As long as you can drain the water when you are done, I would assume it would be okay.
xo Michael
I’ve used these in a Jacuzzi before, it’s a really fun idea, but I agree with Michael, in which it does need to be cleaned out afterwards.
Could you mix everything together except add the citic acid last? I wonder if that will be better this way mixing would be faster and you would lose any fix.
I absolutely love to make my own bath bombs! I like that you can control the ingredients you choose to put into them. I am definitely going to make these amazing bath bombs. I use Himalayan bath salt and really like it, so I am thinking about using it instead of Epsom salt. I have heard so much about Himalayan salt benefits for the skin and body.
Thanks for sharing such a nice and simple step by step recipe. I am definitely going to make these bath bombs.
