DIY All-Natural Bath Bombs

There’s nothing like a warm bath, and these bath bombs just take it to the next level!

Rather than large round balls, these DIY bath bombs are half the size, meaning you can make twice the bath bombs with the same amount of ingredients!

You can feel good knowing that the ingredients are natural and safe for skin and water. I see so many bath bomb recipes that are loaded with artificial dyes and colourants that are just not needed. There are so many wonderful scents in the form of real essential oils and just as many natural colour options, such as:

  • Turmeric for golden-yellow
  • Acai powder for purple
  • Spirulina for blue/green
  • Dragon fruit powder for pink

And more!

Making your own DIY bath bombs is a great way to know exactly what’s going into your body, and the water/environment.

These bath bombs are made from Epsom salts or sea salt (you choose), baking soda (which is alkalising), citric acid (which makes it fizz), an oil (to help nourish your skin), and your choice of essential oils and natural colourants to add colour and fragrance!

If you’d like your bath bombs to look fancier, you can use these metal round moulds which will shape them into round bath bombs (like the ones you find at the store). My simple go-to for bath bomb moulds is a muffin tin. I place the mixture into the muffin moulds, press it down with my hands to ensure it’s packed in tightly, then let them set. It works wonders and saves on needing to purchase any fancy equipment.

DIY Natural Bath Bombs

Relax in a warm bath with your very own homemade bath bombs!



  1. In a large bowl, combine the dry ingredients (baking soda, citric acid, salt, and cornstarch), mixing well. Add 1/2 tsp of colouring and mix well. Add more colouring if you want a deeper colour, but just note that too much colouring will leave a ring around the side of your tub, and the colour will strengthen when you add the witch hazel, anyhow.
  2. In a small bowl, combine the wet ingredients together (oil, and witch hazel) and mix well. Then, add in the essential oils.
  3. Pour the wet ingredients in with the dry ingredients a few drops at a time. Using your hands or a spoon, mix well (if you have sensitive skin, it’s a good idea to wear gloves). If the mixture starts to fizz, you’re adding the wet ingredients in too quickly; just slow it down and ensure you’re only adding a tiny amount at a time.
  4. By the end the mixture should hold together when squeezed without crumbling. You may need to add slightly more witch hazel if it hasn’t reached this consistency. Using a spray bottle with the extra witch hazel can help to evenly coat the mixture.
  5. Working quickly, push the mixture into the mould, muffin tin, chocolate mould or other container of your choosing; pressing firmly to make sure it’s really packed down.
  6. Leave to set for at least 24-48 hours, or until it’s hardened. Once dry, gently tap the mould to release the bath bomb and carefully place in an airtight container to store. Use within 2 weeks.

As always, this is not personal medical advice and we recommend that you talk with your doctor before trying or using any new products. It’s important to check with a doctor before taking this or any new product, especially if taking any other medicine or supplement or if pregnant or nursing. Be sure to check ingredients to make sure there is no risk of an allergic reaction.
