Bath bombs are a marvelous product. They release relaxing scents, look like oversized candy or ice cream scoops, are a fun craft project and make great gifts. So if you have an open afternoon and want to take your baths to the next level without dropping a ton on high-end bath products, here’s your chance to get crafty with homemade bath bombs. Below are some of the top homemade bath bomb recipes.

Basic recipe

Bath bombs are a bit more complex than your usual homemade products, many of which can take as little as two ingredients measured to preference. With bath bombs, you’ll need the following measurements:

  • 2 cups baking soda
  • 1 cup Epsom salts
  • 1 cup citric acid
  • 2 teaspoons water
  • 6 teaspoons olive oil
  • 4 teaspoons essential oil of your choice
  • Food coloring (any color you want to shade preference)

You’ll also need a bath bomb mold (a craft store will be your friend here), a bowl, a whisk, a spoon and a jar.

From there it’s a lot more simple than it looks. Place the dry ingredients in the bowl and mix them together with the whisk. Now you’ll combine your wet ingredients in the jar and stir. This is where you’ll pick your essential oil(s) and food coloring. If you use multiple essential oils, make sure they all combine to equal four teaspoons.

Then add the liquid to the dry mixture a little at a time, stirring well all the while. You’ll end up with something that looks like colored sand. Pack the mixture into the mold as tightly as you can, and then tap the bomb out of the mold.

If you can’t get it out of the mold, either try to pack it tighter, leave it in for a minute or add a very small bit of water to your mixture (too much water and the mixture will expand).

Let your bath bomb dry for at least a couple hours or so before use. And there are your homemade bath bombs! These will keep for up to a few weeks.

Rainbow bath bomb

Once you get the basic recipe mastered, you can begin to customize. Mix several batches of the recipe above, but use different food coloring for each batch. Then you can layer different colors in the mold. Common looks include rainbow layers, white (no food coloring) and pastel layers, stripes of two bright colors and half-and-half balls with one color on the top and the other on the bottom. Feel free to get as creative as you’d like.

Bath bomb additives

Some bath bombs you’ll see have fun little surprises at the top like flowers and herbs to infuse a bath with some botanical goodness. Simply place those items at the bottom of the mold and pack the mixture around it.

Some other fun ideas even involve candy, like Sweethearts and sprinkles. You can also add glitter, chocolate chips, colored sugar or whatever you can imagine. Anything that will dissolve in water or wash down the drain easily is fair game. The key here is to have fun with your bath time confections.
