Bath Bombs

Bath bombs are easier to make than you may think. Not only are they easy, but they make fabulous gifts for anyone in your life that enjoys a quick "spa" treatment at home! Simple spa treats that make great gifts and can quickly be personalized! How great is that?!

You can add your own signature and make them much more personal by adding essential oils, food coloring, gift wrap, and personalized labels. The wrapping ideas are only limited by your creativity and imagination. In addition to Bath Bombs, you may also enjoy A Simple Mild Home Detox Bath, which you can also package as a great gift too.

Gift bags with bows, colored tissue paper or colored cellophane make them look professionally wrapped. I also consider the scents my loved ones like, so it makes them feel extra special, and even more personal.

Lavender, Orange Peel, Sandalwood and Eucalyptus are really nice for scents (just add slow, a little goes a long way). And I love the essential oil sets from Eden's Garden, which are easy to find available on Amazon, or from Eden's Garden directly. Also Doterra Essential oils are fantastic! Both sites give you a generous amount of oil that can be used for many things, not just bath bombs, essential oils have tons of uses!

Cook Time

Prep time: 20 min
Ready in: 20 min
Yields: 5 bombs

Ingredients -yields 5

  • 2 cups Baking soda
  • 1 cup citric acid, available at local health food store
  • 2 teaspoons massage oil,or see next item, or
  • 2 teaspoons essential oil and 2 olive oil or coconut oil
  • a few drops food coloring (optional)
  • a spray bottle Witch Hazel (binding agent)
  • 60 mm 2 part plastic ball mold/or other mold
  • 10 % corn starch optional as a binding agent

  1. Mix the citric acid and baking soda in a large bowl (and 10% corn starch if you are using it). mix these ingredients well, use an electric mixer if desired.
  2. Add in 2 teaspoons of scented massage oil (or the 2 tsp essential oil/coconut or olive oil). The scent is personal, so start with a small amount and add more until you get the desired scent, add food coloring if you are using any, and continue to mix this together well.
  3. The next step can be a bit tricky because you don’t want your bath bomb to start fizzing. Start by adding a couple of fine mist sprays of witch hazel to your mixture and mix more again.
  4. You will continue spraying until the mixture will clump in your hand when squeezed. (It takes multiple sprays, however this will depend greatly on your local climate) you'll start to get a hang of the consistancy with a little practice, and it will take some practice.
  5. Fill one half of your mold. Pack it tightly. Be prepared for the balls to expand. It's best to use a meatballer, or other round shape about 1.75 OD, no larger. Or, you can ball them and lay them on parchment paper and they will flatten like fun fizzy frisbies.
  6. Fill the other half of the mold and place them together—don’t snap together. Slightly overfill each half. When you push the two halves together they will became a ball. And you want them to bind together as well as possible.
  7. Gently remove the ball from mold. If you have any problems with the ball coming out to easily dump the mixture back into your bowl, add a few more mists of witch hazel (carefully), mixed well and then try again
  8. Place on parchment paper, or wax paper, and allow to dry. The balls really don't need to sit for long, a few hours should set them well enough, this will depend on size. I've made huge ones that I've let dry over-night.
  9. Decorate, place on display or use them and enjoy!

Tips and suggestions

  • Add flower petals to the mix when making
  • Blue or green food coloring gives the tub water a nice color
  • Suggested oils to use- coconut oil, jojoba oil, olive oil
  • Add Epsom salt granules for an exfoliation experience
  • For "kid" bombs, add surprise small tub toys into the center of each ball when binding them together
  • When wrapping for gifts consider themes, wrap to look like an actual bomb, a bowling ball, or other sports ball for someone that loves a certain sport.
  • As you master your recipe, experiment with different mold shapes. Easter eggs for holidays, square, round, heart shape molds for Valentine's Day.

If you want your balls to foam, instead of fizz, use this recipe...(same instructions above)

10 parts baking soda

5 parts citric acid

2 parts Sodium Lauryl Sulfoacetate

Witch Hazel

(note this is not the same as sodium laureth sulfate or sodium lauryl ether sulfate)


You're now ready to enjoy your bath bombs or package them for special gifts!

Run a hot bath, light some candles, maybe add some mood music, place in the tub, get in and relax! The fuzzy bubbly feeling feels very nice near sore feet, or just bubbling through the water...
