Natural Bath Bomb Recipes

Make your own all-natural relaxing, restorative bath bombs, free of commonly-used harmful chemicals

.There is nothing quite like a nice relaxing bath to soothe away the aches and pains of a hard day’s work or play.  It’s an opportunity to do something just for you, get a little quiet time and unwind. The restorative properties of water alone are worth the effort, but adding a bath bomb makes it even better.

Basic Bath Bomb Directions.

Use the following basic methodology with the suggested choices of essential oil, botanicals and micas to make the most divine bath bombs.


  • Citric Acid 250 grams
  • Epsom salts 125 g
  • Sodium Bicarbonate 500 grams 
  • 1 tsp essential oil of your choice (optional)
  • 1-2 tablespoons botanicals such as Rose Petals (optional)
  • 1/4 teaspoon mica as a colourant (optional) 
  • 1-1/4 teaspoon of castor oil
  • Water in a spray bottle 


  • Large bowl (to mix your ingredients in)
  • Kitchen scales
  • Sieve or sifter
  • Standard measuring spoons
  • Spray bottle
  • 10 x bath bomb mould sets


  1. Using a sifter or sieve to get out any lumps, combine your citric acid, Epsom salts and sodium bicarbonate in a large bowl.  Mix well until they are fully combined.
  2. Mix in your mica and botanicals (optional).
  3. Make a well in the centre. Add the castor and essential oils. Using your fingers start mixing the ingredients together.  Be aware that if you have any cuts on your hands this will sting and you will need to use rubber gloves. 
  4. Continue mixing with your hands until the mixture is fully combined. 
  5. Using the spray bottle, add small amounts of water (5 to 10 sprays at a time) to the mixture, making it damp and begin to bind together.  You want to add this gradually while continuing to work the mixture with your fingers. Not enough water and the mixture will not bind together. Too much water and it will become too wet.
  6. Your mixture is ready when it looks like damp sand and holds together when it is squeezed.
  7. When you are happy with the consistency of your mixture, quickly fill both halves of the bath bomb mould and then press them together and give them a squeeze to join the halves together. Slightly overfilling the moulds works well and helps the two halves stick together.   
  8. Set the filled bath mould aside for half to one hour to dry.
  9. Once they are dry remove the bath bombs from the moulds by taking each half and giving them a twist to release the bomb from the mould.   

Cleaning Tip: Like any bath oil, the oils in bath bombs can stick to the bathtub. If using mica colourings, the oil will trap the mica and sometimes makes a visible coloured ring around the bath. To easily remove, just put a bit of soap on a washcloth and wet with warm water to wipe away the oil and colour.
