Sodium Bicarbonate is a staple ingredient within bath bombs, it helps to soften water and soothe the skin. When combined with bath water and citric acid, carbon dioxide is released creating fizzing bubbles.

Fizzing Bath Bombs


  • 300g of Sodium Bicarbonate
  • 150g of Citric Acid
  • 5-10ml of essential oils
  • 5ml of carrier oil (e.g. Sweet Almond oil, Jojoba, Coconut Oil, Rosehip Seed oil)
  • Spray bottle with water or try one of our hydrolats for additional therapeutic properties
  • Latex gloves
  • A mould or tray (you can buy bath bomb moulds or simply use a chocolate mould or ice cube tray). It’s worth noting that smaller bath bombs are a bit easier to make and less likely to crumble – particularly if you’re making them for the first time and aren’t familiar with the process
  • Optional: dried herbs or flowers, cosmetic colours/dyes if you want to create different colours

  • Ensure that you’re wearing your latex gloves as the citric acid will sting if it gets into any small cuts or broken skin. Sieve the Sodium Bicarbonate and Citric Acid into a glass or metal bowl and mix thoroughly with your hands.
  • Add your chosen carrier oil and essential oils. The oils shouldn’t cause the mixture to fizz but mix in quickly if any fizzing does occur.
  • If you want to make different coloured bath bombs – separate out your mixture into different bowls and add in your chosen colours until you have your desired shade. Mix quickly, rubbing between your fingertips as if you’re making a crumble topping.
  • Next, spritz in water or hydrolat, a tiny bit at a time, until the mixture starts to hold together when squeezed in your hand. You need to work quickly at this stage so the mixture doesn’t start to set.
  • Pack the mixture into your moulds, compress firmly and leave to set.
  • If you’re using a ball-shaped bath bomb mould slightly overfill each half then press together firmly (do not twist). Leave for a few minutes, then gently tap to remove one half of the mould. Leave the bath bomb to set in the other half of the mould for around 20 minutes.
  • Remove the bath bombs from their moulds and place them somewhere warm and dry, so they can dry out properly.
  • Wrap them in cling film and store in a dry place, or gift wrap them for friends and family. The bath bombs will fizz best when used fresh so try to use them up as soon as possible.
