DIY - Bath Bombs

This is what I need after a long hard day... a nice relaxing bath with a couple of these thrown in. I first read about these in one of those DIY magazines and thought to myself, 'I could easily make these myself', so that was my mission, and Im happy to say my mission was completed successfully. So if you, like me want to know how to make your own homemade bath bombs then look no further. 

You will need:
1) 300g Bicarbonate of Soda2) 100g Citric Acid3) 10ml Fragrance or Essential Oil of your choice
4) Food Colour 
5) A large mixing bowl
6) Suitable moulds to shape the bath bombs
7) Kitchen scales
8) A hand sprayer containing clean cold water

1) Measure out the bicarbonate of soda and the citric acid into the mixing bowl, seiving if necessary and thoroughly mix together until you have a consistent texture.

2) If using liquid food or cosmetic/soap colours, add, in drops, enough colour to make the shade you want, mixing it in quickly to avoid it fizzing up. If using a powdered colour, simply add, a little at a time, and mix until you have your desired shade.

3) Blend in the colour until you have a consistent shade throughout the mixture to avoid 'spots' especially important with powdered colours.

4) Measure 10ml of either fragrance or essential oil into mixture. Most essential or fragrance oils will not cause the mixture to fizz, but certain citrus oils may, so if this happens, mix in quickly and thoroughly. Do not leave the mixture to stand or it will slowly start to set.

5) Now, a little at a time and working the mixture all the time, spray a little water on it with the hand sprayer. Mix continuously to avoid it fizzing-up in the bowl and ONLY ADD ENOUGH WATER TO HAVE THE MIXTURE START TO HOLD TOGETHER WHEN LIGHTLY SQUEEZED IN YOUR HAND.

6) Test the mixture by squeezing some in your hand. It should JUST hold together and not be too damp.

7) Once this point is reached you need to work quickly to compress the mixture into your moulds.

8) Leave to set in the mould for 20-30 minutes

9) After 20-30 minutes they should be quite hard. Simply take the bath bomb from the mould and leave it to dry. If they've not hardened enough, just leave them in their moulds a little linger and test again.

10) There, you've made your very own bath bombs, now all you have to do is run a bath, throw one in and relax and enjoy! 

I hope you enjoyed this quick little DIY post and, good luck in making your own bath bombs. There prefect for these cold nights leading up to Christmas.

Thanks for reading and have a good day,

  1. These are awesome! This is probably a really stupid question, but where can you get citric acid from? x

    1. Hi, its not a stupid question :) you can get citric acid from your chemist/pharmacy or large supermarkets

  2. Hi, which sort of moulds would you suggest using and which did you use yourself? I'm the same, I've been meaning to try this for sometime now! :)

    1. Hi, you can use any silicon mould you have available it doesn't really matter on the shape or size, for me i used a minni muffin silicon tray (make sure to really clean it before and afterwards)
