How to make bath bombs

Updated: Mar 6, 2023

These are great to make with kids for fun at home, or for home made gifts for friends and relatives. They can also be made to be more therapeutic, depending on your need, eg. coughs, colds, insomnia, skin conditions that need soothing - the bicarb and citric acid are a lovely pH for the skin, as are the oils - no need to moisturise after one of these bath bombs!

You will need:

  • Ideally mortar and pestle but bowl and spoon/fork will do

  • Bath bomb moulds or cookie cutter shapes


  • 1 tablespoon citric acid

  • 3 tablespoons bicarbonate of soda

  • 3 teaspoons oil (coconut, sweet almond, grape seed, nut oil, any oil you like really)

  • 20 drops essential oil

  • 1 teaspoon of dried herbs or flowers (optional)

  • 1 teaspoon edible decorations (cake decorations can be really pretty and dissolve in the water, so edible glitter, icing sugar hearts or flowers, etc.)


  1. Combine the citric acid and bicarb.

  2. Mix in the oil and essential oil until thoroughly blended.

  3. Fold in the herbs or flowers - Lavender and/or Chamomile work well. Tip: Only add once you have the powders and oil well blended, otherwise they will break.

  4. Press gently into the bath bomb moulds. If you push/compress the mix into the moulds too tightly, it takes a lot longer to dry/harden.

  5. Leave for at least 24 hours. Some take longer, depending on the size of your bath bomb mould and how tightly you have packed it.

  6. Store in an airtight container in a cool, dry place.

  7. Use within about a month otherwise they tend to go very soft and end up more like bath salts, although they still leave your skin with the same luxurious moisturised feel to it.

What we can use these for:

  • For coughs, colds and flu, you can add Eucalyptus and/or Lavender essential oil, and also infused oils (see here for more info about infused oils), perhaps infused with respiratory herbs.

  • For insomnia, use Lavender and/or Chamomile flowers and essential oil, and/or infused oils with either of these herbs, or other herbs used for sleep issues.

  • For skin issues, eg. dry skin, eczema, any skin condition that needs soothing.

  • For aching muscles, use Black pepper essential oil, Ginger essential oil, again infused oil works well here, perhaps use one with St John's Wort which is good for nerve pain.

Where to get the above ingredients from:

The best place is New Directions as they stock so many raw ingredients to make your own bath bombs, hand creams, ointments, lip balms, etc. Check out my post here on how to make infused oils.

Here's some I made earlier:

  • For this one, I used Sweet Orange essential oil and some Lemongrass essential oils, and sprinkled edible glitter into the bath bomb mould before I pressed the mixture in:

Orange and Lemon grass essential oils were added to this one.

  • For this one, I added Lavender flowers, essential oil and the oil I used was infused with Lavender flowers:

For insomnia and also coughs, colds - Lavender has champhor which eases stuffy noses.

  • For the one below, I added the pink and white hearts to the mix (step 3 in the Method above), and used Rose Geranium and Ylang ylang essential oils. The pink and white hearts are cake decorations:
