How to Make Bath Bombs at Home

Bath bombs are the perfect addition to a warm bath to help you relax and unwind. But they can be costly to purchase on a regular basis.

Not to worry though! Follow the instructions below to make your own bath bombs at home that look and smell amazing, and add a fantastic fizz to your bath.

What You’ll Need

Before you start, you’ll need to pick up the following ingredients and equipment if you don’t already have them:

  • Glass mixing bowl
  • Spray bottle
  • Gloves
  • Moulds
  • Sieve
  • Citric acid – 1 cup
  • Baking soda – 2 cups
  • Essential oil – 20-30 drops
  • Sweet almond oil, apricot oil or olive oil – 1 tablespoon (optional)
  • Food colouring – 15-20 drops (optional)
  • Water

If you don’t have a bath bomb mould, you could use alternatives such as chocolate moulds, muffin trays or ice cube trays, or for round bath bombs, cut a tennis ball in half.

Method

  1. Mix the citric acid and baking soda together thoroughly in the mixing bowl.
  2. Add the essential oils to the mix and the optional extra oil and food colouring if you’re using these. Mix together quickly with your hands before the mixture starts to fizz. Get rid of any clumps by rubbing between your hands.
  3. Spray very small amounts of water on to the mixture and continue mixing the ingredients together. Aim for a consistency where the mixture is crumbly but just holds its shape when squeezed.
  4. Pack the mixture tightly into the mould – if you’re using 2-part moulds (e.g. 2 tennis ball halves), slightly overfill each half and push together firmly. Tap the moulds to release the bath bomb.
  5. Leave the bath bombs to dry for a couple of hours in a warm and dry area. Avoid leaving them in direct sunlight.

Notes

  • Make sure to use the bath bombs within a few weeks of making them as they will start to lose their fizzing power if left for too long.
  • Bath bomb crumbling when removed from the mould? This could be because the mixture needs compressing more, or is too dry. Pack tightly into the moulds and leave for a couple of minutes before tapping them out. If that doesn’t help then spray a tiny bit more water on to the mixture.
  • If the bath bomb extends then you’ve added too much water and the fizz reaction has started. Rescue this by adding more baking soda and citric acid (2 parts baking soda to 1 part citric acid).
  • To begin with, you may want to start making your bath bombs in smaller batches until you have got the hang of the process. Once mastered, you can make in bulk.

Good luck making your bath bombs! These are relatively quick and easy to make, and would make a great present idea for bath lovers.
