Finished rose and chamomile bath bombs

These floating rose and chamomile bath bombs are surprisingly quick and easy to make and are ideal as gifts. There are lots of possibilities: different shaped moulds, herbs, essential oils, glitter – this recipe will accommodate them all!

What you need

  • 1 1/2 cups of bicarbonate of soda
  • 1/2 cup of citric acid (I buy mine from eBay as it can be difficult to find in shops)
  • 2 tablespoons of oil – sweet almond oil, grapeseed oil, olive oil etc
  • Handful of dried rose petals
  • Handful of dried chamomile
  • Rose essential oil
  • Lavender essential oil
  • 2 medium sized bowls
  • 1 small bowl
  • Bath bomb moulds or other moulds (I used fairy cake tins)
  • Cup

How to make them

Time needed: 20 minutes

  1. Measure out your ingredients: The nice thing about making bath bombs is that the quantities don’t have to be pinpoint accurate like they do in something like soap making
  2. Mix base ingredients: Put all of your bicarbonate of soda and citric acid into a bowl and mix together well. These are the ingredients that react with eachother and fizz when the bomb is put in water
  3. Transfer 1/2 cup: Put 1/2 a cup of your bicarbonate of soda and citric acid mix to another bowl. The reason it is only 1/2 a cup is because it is much easier to mix in your oils and if it does start to fix, you haven’t lost a whole batch of ingredients
  4. Add dried fragrance: Add some of your dried rose petals and dried chamomile to this and mix
  5. Bath bomb mix

  6. Mix the essential oils: I used 7 drops of rose oil and 2 drops of lavender per 1/2 cup of ingredients. Add your essential oils to 1/2 tablespoon of oil and mix (the amount of oil you need may vary slightly from this recipe depending on the quantity of dried flowers you used)
  7. Mix oil with dried ingredients: This part needs to be done quickly or the mixture can fizz up in the bowl. Clear a small area of space at the side of your mixture and pour in the oil and mix quickly. It’s best to do this stage with your hands. When you can squeeze the mixture in your hand and it forms a lump (you don’t want it to feel wet) it is ready to pack into moulds
  8. Grease moulds: Lightly grease your moulds with oil
  9. Put in moulds: Press your mixture down into the mould firmly

  11. Repeat: Keep doing this 1/2 a cup at a time until all your mixture is gone
  12. Leave: Leave your bath bombs in their moulds for 48 hours so they have time to set and dry out
  13. Press out of moulds: Very gently remove your bath bombs from their moulds. I used a cake tin and just had to press the bottom of each mould

  15. Use: Drop into hot water and enjoy the fizz

  17. Storage: Package the bath bombs in plastic to protect them from water and damp

    how many bombs does this recipe make?

  • Gemma Garner on December 20, 2010

    I got 6 large bombs from this recipe – I used a fairy cake tin :) If you use half a bath bomb mould (plastic mould with two halves), you can stretch this to 12.
