If you’ve ever wanted to make your own bath bombs but felt overwhelmed by the idea of it, you are not alone. I was the same way for a long time.

But once I started, I learned just how easy it was! And I finally found something that makes it even easier: a DIY Bath Bomb Kit that comes with everything you’ll need to make your own!

It takes the guesswork out of the process so you can focus on the fun part, making fizzy, aromatic bath bombs from scratch.

Here is this super simple bath bomb recipe, along with where to find this amazing DIY kit to use time and time again.

Why Make Your Own Bath Bombs?

DIY bath bombs are more than just fun to drop into the tub. They’re a self-care ritual. When you make your own, you know exactly what’s going into them, no mystery chemicals, no artificial fragrances. Just clean ingredients and skin-loving essential oils.

My kids love using bath bombs every time they take a bath. So I love making them custom to what they need in the moment.

Feeling sick? We can make sinus saver bath bombs to help them breathe. Need to calm down before sleep? Make some relaxing ones!

Bath bombs also make amazing gifts. Whether you’re making them for yourself, a friend, or a special occasion, handmade bath bombs always feel like a thoughtful treat.

Easy Bath Bomb Recipe

Here is one of the recipes from the bath bomb kit! I kind of mixed the two recipes into one since I love how the swirls look.

Ingredients Needed:

1/2 cup citric acid
1 teaspoon SCI powder
2 tablespoons Natrasorb bath powder
2 teaspoon gold mica powder
2 teaspoon blue mica powder
2 teaspoon almond oil
1/2 teaspoon castile soap
18 drops sweet dreams essential oil
1 cup baking soda
1/4 cup corn starch
1/2 teaspoon water (+plus more if needed)

Instructions:

Mix your dry ingredients (SCI powder, citric acid, Natrasorb bath powder, baking soda, and cornstarch).

In another bowl, mix the almond oil, castile soap, water, and essential oils.

Slowly add the wet ingredients to the dry ingredients, mixing the entire time. Go slow, if you go too fast it will bubble up!

Mix with your hands until it feels like damp sand. If it forms a ball in your hand, that is good enough. If not, slowly add a bit of water until it does.

Divide into two bowls. Add the blue and gold to each separate bowl and mix until you get your desired color.

Layer the colors on top of each other in the mold. When the mold is full, take a toothpick or back of a spoon and swirl it together a bit.

Then put the two bath bomb pieces together and squish until combined.

Slowly take the bath bomb mold off and let your bath bombs dry out for at least 24 hours, or until they are fully hard.

You’ll end up with gorgeous, fizzy bath bombs that smell amazing and leave your skin feeling soft and pampered.

Notes:

As you can see from the pictures, I added a bit too much almond oil into my mixture which made the bottom of my mold squish at the bottom. It still worked totally fine, just wasn’t a “perfect” circle.
After making the first bath bomb, I noticed they were HUGE! So I only did half circle bath bombs for the rest, so that’s why you can see a big line through them. Yours won’t look like mine, they will look so much better!
You can use infused oils. A lavender infused oil will be amazing!
