DIY Bath Bombs |
This post is sponsored by Carnival Cruise Lines.

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 a bath bomb 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.

This year I’ve teamed up with Carnival Cruise Lines to share a variety of tips and ideas inspired by my time on their ships. We’ve covered cocktails, DIY travel accessories, a handmade serving tray, and so much more. Now, inspired by their Cloud 9 Spa, we’re going to tap into the relaxing side of things.

As much as I love an adventurous vacation full of activity and sightseeing, I equally enjoy a day of pampering. Whether it’s a massage, facial, or just hanging out in a thermal suite in the Cloud 9 Spa, I’m a firm believer in the benefits of relaxation.

In an effort to bring some of that relaxation home with me 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.

Begin by measuring out and whisking together your dry ingredients in a large bowl. I used a coloring pigment for my 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. 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!

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 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 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!

  • Camilla t ramagli at

    Where do I find the dry color pigment ingredients?

    • Michael Wurm, Jr. at

      There’s a link to the pigments I used in the post above.

    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 to make something special. Great post!

  • Triela at

    Does this recipe make the bath water turn the color of the pigment, or does it just make the bath bomb a pretty color?

    • Michael Wurm, Jr. at

      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.

    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!

    • Michael Wurm, Jr. at

      The best part about making them is that you can customize them to your liking. Have fun crafting!

  • Eddie Rios-Stroud at

    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!

    • Michael Wurm, Jr. at

      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.

    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?

    • Michael Wurm, Jr. at

      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! 🙂

    Would it work to use liquid food colouring instead of the dry colouring pigment?

    • Michael Wurm, Jr. at

      I haven’t tried it with liquid food coloring. You could try, but I can’t guarantee any specific results.

      xo Michael

  • Jeanette at

    For the recipe provided, how many bath bombs of your size mold, will this yield?

  • Roxana at

    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!

    • Tracy at

      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?

  • Natalie at

    What size mold did you use to yield 4 bath bombs?

  • Michele at

    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.
