Here's everything you'll need for the perfect DIY bath bomb:

  • 1 cup baking soda 
  • 1/2 cup citric acid 
  • 1/2 cup Epsom salt
  • 1/2 cup cornstarch
  • 3/4 tbsp. water
  • 2 tsp. essential oil (lavender, eucalyptus, rose, orange, and lemongrass are popular for the bath)
  • 2 tbsp. oil (jojoba, sweet almond, coconut, olive, or even baby oil)
  • A few drops of food coloring.
  • A mold of your choice, such as regular or mini-muffin tins, candy pans, or round plastic molds specifically for bath bombs
  • Optional: Dried flowers or sugar cake decorations, like flowers or stars

Bath Bomb Instructions

Step 1: With the exception of the citric acid, mix the dry ingredients in a large mixing bowl. 


Step 2: Pour all of the liquid ingredients in a jar with a top. Close the jar and shake it vigorously.


Step 3: Pour the liquid mixture into the bowl of dry ingredients, and use your hands to combine and meld together. At this point, add the citric acid. You'll probably notice a slight fizzing reaction because of the citric acid. No need to panic, as this is normal.


The mixture should be a bit crumbly (similar to the consistency of wet beach sand). Whatever you do, don't add water at this stage, or the bath bomb will fizz prematurely and be ruined.

Step 4: Mash the mixture into your chosen molds very tightly. You can overfill the molds slightly and use a spoon or glass to press the mixture in as tightly as possible. Immediately loosen the bombs from their molds onto wax paper and let them dry overnight.


Step 5: Give the bath bombs a day or two to completely dry before using them or wrapping them up as gifts.


Step 6: Pop one in the bathtub, enjoy the burst of colors and fizz and inhale the released aromas. Turn on some of your favorite music or a podcast to accompany you while you soak, or simply slide into the bath and enjoy all of your hard work.


Packing Your Bath Bombs

These bath bombs make perfect gifts (for others or yourself—self-care is important!). You can put both large or small ones in cellophane gift bags (like the ones you'd typically buy for cookies) or stack smaller ones in a wide-mouth mason jar. Make a few batches using different colors and add various essential oils for an array of scents if you'd like some variety. Bath bombs typically last about six months as long as they are packaged well in airtight jars, Tupperware containers, or sealed plastic bags and stored in a dry environment like a cupboard. Storing them in the bathroom or out in the open air isn’t ideal as steam and moisture cause the citric acid to lose its potency and your bath bomb will not initiate the fizzy effervescence you’re after.
