You will not believe how simple it is to make your own luxurious DIY Bath Bombs. Once you make these fizzy bath bombs, your bath time routine will feel like a day at the spa. Plus, they are great for gifting to family and friends.

What you Need:

The best part of ‘homemade’ is that you know exactly what ingredients go into the products.


  • Baking soda – 1 cup
  • Corn starch – 1/2 cup
  • Citric acid – 1/2 cup
  • Epsom or Himalayan bath salt – 1/2 cup
  • Coconut oil, fractionated or melted – 3 tbs
  • Essential oils – 2 tsp
  • Water – 1 tsp
  • Bath bomb molds
  • Large & small mixing bowl, spatula or whisk


Where to find: Citric acid is used for canning, so look for it near the mason jars or in the organic spice aisle at your grocery store. Also, quality fractionated coconut oil and pure essential oils can be found online, here. Round fillable ornaments, plastic eggs, silicone ice cube or candy tray or soap molds will work as bath bomb molds.


Optional: Corn starch makes the bath water feel silky and slows the citric acid reaction process down, so use it or not. You can add a drop of food coloring or teaspoon of mica in the color of your choice to make bath bombs colorful. Lastly, you can add finely chopped, dried botanicals like lavender or rose petals.

What you Do:

First, gather all your materials. You need to work quickly to ensure the materials remain flexible and easily set in the mold. However, slowly mix the dry and wet ingredients so that you do not activate the citric acid. This makes the bath bombs fizz. Lastly, keep these DIY bath bombs in a sealed container to maintain freshness and eliminate moisture from disrupting the form.


  1. In a large bowl, mix 1 cup of baking soda, 1/2 cup of citric acid, 1/2 cup of Epsom salt and 1/2 cup of corn starch.
  2. In a small bowl, pour 1 tsp of water, 3 tbs of coconut oil, and 2 tsp of combined essential oil. Stir.
  3. Slowly, mix the dry and wet ingredients together. Stir.
  4. Pack the mixture into each half of the molds generously. Press molds together.
  5. Allow to sit for 24 hours before removing from mold to use or store.

DIY Bath Bomb Scents

When using essential oils, make sure that the oils are pure. Most importantly, use oils that are safe for the skin and be familiar with any that you may be particularly sensitive to. Some citrus oils, like lemon or orange, can be used on the skin, but may make your skin sensitive to the sun. Just FYI, if you are planning a day outdoors, wear sunscreen or avoid topical citrus oils.


Depending on the essential oils that you add, you can create the scent, mood and health benefit that you desire. So, here are a few oils to try.

Inside & Out

Uplifting aroma + improves skin complexion: Try helichrysum or tea tree oil or juniper berry.


Pure Joy

Calming aroma + skin purifying: Try bergamot or magnolia or eucalyptus.


The Great Outdoors

Refreshing, woody aromas + creates calm, grounded atmosphere: Try Douglas fir or sandalwood or cedar wood.


Everybody Calm Down

Floral, stress relieving aroma + skin calming: Try lavender or rose oil.


Fresh and Fruity

Uplifting aroma + air purifying, antibacterial: Try orange, lemon, lemongrass, or grapefruit.
