Introduction: DIY Easy Bath Bombs

Looking to use bath bombs, but can't find a particular scent? Or maybe you just want to enjoy a bath bomb at a cheaper price. Either way, this do it yourself guide will show you the steps to take to create your own bath bombs. And you can give them any scent you'd like! It's really not all that hard. It just might take a little practice to get them looking nice.

Step 1: Determine Molds

So you made it to step 1. You must be serious about this. Well, the first thing you're going to want to do is figure out what kind of molds you'll use. Bath bombs don't need to be round. They can be any shape you'd like. You can find a wide variety of molds on Amazon:

You'll see that I chose to use a rubber Valentine heart shaped mold that wasn't intended to be used for bath bombs. It's not the most wise idea because it's more difficult to pack them down when the mold is flexible, but it still works.

Step 2: Get Ingredients

What you'll need:

  • Rubber Gloves (optional)
  • 1/1 cup baking soda
  • 1/4 cup citric acid (Be careful with anything acidic on counter tops)
  • 1/4 cup Epsom salt (helps sore muscles)
  • 1/4 cup cornstarch
  • 1 teaspoon all natural food coloring (optional) (natural powdered food coloring activates when wet in the tub and will not stain)
  • 1 tablespoon coconut oil, melted/warm
  • 1/2 teaspoon water (do not use more than this)
  • Up to 10 drops of your essential oil(s) of choice (lavender is great for relaxing)

(makes approx 3 regular sized bath bombs)

Step 3: Mix the Dry Stuff

In a large bowl whisk together:

  • The baking soda
  • The citric acid
  • The Epsom salt
  • The cornstarch
  • The powdered food coloring (if using)

Step 4: Melt the Coconut Oil

Melt the coconut oil in a small bowl. 15-20 seconds on high in the microwave should do the trick if the oil was at room temperature.

Step 5: Mix the Wet Stuff

In a separate bowl from the dry ingredients, combine:

  • The melted coconut oil
  • The water
  • The essential oil(s) (chamomile, lavender, peppermint, orange, etc)

Step 6: Carefully Combine

While continuously whisking, very slowly drizzle the liquid ingredients into the dry ingredients until well combined. The outcome should be similar to a dry, crumbly sand and should not be a "wet" consistency.
Please Note: If mixture gets too wet, it will activate the fizzy part of the bath bomb too soon!

Step 7: Place in Molds

Pack the mixture into each side of each mold tightly. The trick to making the bath bombs harden is making sure you've packed them down tightly. In using a rubber mold, my bath bombs didn't quite come out clean because it's difficult to pack them tightly in a flexible mold. But removing them from such a mold was very easy. After placing the mixture into the molds, press each side of each mold together. Let them sit overnight.

Step 8: Remove From Molds

After bath bombs have sat overnight or for several hours in their molds, lightly tap around each mold with a spoon (unless using a rubber mold like I did). This should loosen up the molds. Carefully open and remove each bath bomb. You'll notice from the pictures that I had to re-pack my bombs because they weren't packed tight enough. So it ended up making less.

Step 9: Package and Store

It's up to you how you want to store your bath bombs. You can use a hair dryer on shrink wrap baggies to package them up nicely. Or you can use cling wrap like I did. You can even leave them in individual plastic molds and give them out as gifts to others. The choice is yours.

Step 10: Enjoy!

When you're ready to use a bath bomb, simply unwrap one and place in warm tub of water. The bomb will fizz and dissolve. All you have left to do is enjoy!
