Bath Bomb Recipe


300g (1 cup) 

600g (2 cup) bicarbonate of soda (baking soda)

1 tspessential oil or fragrance oil

1 tsp herbs, glitter, mica or liquid colour, dried flowers

5g (1tsp) carrier oil such as sweet almond, jojoba or olive oil

 Cold water to be placed in a small spritzer or spray bottle.


  1. In a bowl mix the citric acid and sieve in the bicarbonate soda. Make a well in the middle and add the other dry ingredients.

  2. Sprinkle in the colour and fragrance. This is where you should add the liquid colour if you prefer to use one too. If the mixture begins to fizz its ok just cover it up with the dry ingredients.

  3. Mix all ingredients together; it is safe for you to use your hands.

  4. Ensure all the ingredients are mixed together thoroughly.

  5. Add in the binding ingredient – the oil.

  6. Add the water into the mixture using the spray bottle, add a little at a time, mixing it together with your hands until your mixture becomes damp resembling damp sand and should hold together well in your hand. If it begins to dry and crumble add some more water.

  7. Now add the mixture into your bath bomb mould as quick as you can before the mixture begins to dry out. Again if it begins to dry add a little water using the spray bottle to the mixture.

  8. When placing in the bath bomb mould ensure you press the two halves firmly together. You can either leave it in the mould over night or place on a surface to harden, roughly around 24 hours
