Homemade Natural Bath Bombs Recipe

Bath bombs are something that have been around for a while, though I only jumped on the bandwagon and started using them when I began created some of my own to go in my natural DIY pamper package as a gift for my friends and family, and I had a few spare that I could use. There’s nothing like a warm bath, and these salt bath bombs just take it to the next level!

As we’re heading into Autumn here in Aus, the weather has been getting a little chillier (in fact, I’m sitting here in my warm jumper, wrapped in a blanket right now!), so that means baths will become a regular occurrence for me now.

So, in light of this, I wanted to share my favourite go-to bath bomb recipe which I absolutely love (and requires no special equipment!), in the hope that you will love it just as much as I do! Enjoy those relaxing baths! Xx

Non-Toxic Bath Bombs

Many of my friends and family were using bath bombs long before I started, but I put off using them for a long time because a lot of the store-bought versions generally contained artificial ingredients like dyes and fragrances, which I didn’t want my body to soak up and absorb while I was relaxing in the warm water.

So I went on the search for a natural alternative, and found this babe of a recipe. 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 oil to add that enticing scent we all love about bath bombs (their smell just fills the room 😍).

If you like, you can even package them as a gift for a loved one, or they can be enjoyed by you in a relaxing bath anytime!

How to Make These Natural Bath Bombs

Bath bombs take only a few minutes to make, and majority of the ingredients you can already find at home in your pantry! The ingredients you’ll need to have on hand to make these exquisite balls of fizz include:

Baking Soda

This compliments the citric acid and plays a part in the fizzing action.

Citric Acid

This is an ingredient many people don’t typically have on hand in their kitchen as it isn’t really a common ingredient found in many other recipes. However, it’s necessary for the fizzing reaction.


I usually use organic cornstarch powder in this recipe, and what it does is provide the silky feel we all love about bath bombs.


You can use sea salt, Epsom salts, or any other favourite salt option you have.


A simple oil like almond oil, coconut oil, or olive oil work just fine.


I tend to use water, but I’ve read that witch hazel works well and provides a skin soothing effect.


The options are endless here. I often choose lavender as I just LOVE this fragrance. However you can choose whatever scents you like. Go crazy and see what works for you! You can even add some dried herbs to spice it up a little.😉

If you’d like to mix up the colour, using natural dyes work wonders. I don’t tend to use any colouring as the plain white colour is fine for me.

Bath Bomb Moulds

If you’d like your bath bombs to look fancier, you can use these metal round moulds to give them a bit of a professional look, or if you don’t mind too much, you can simply shape them into round balls with your hands. My simple go-to for moulds is a muffin tin. I place the mixture into the muffin moulds, compress it together with my hands to ensure it’s packed tightly in, then let them set in there. It works wonders and saves needing to purchase any fancy equipment, as I already have them on hand from my muffin-making days!

Natural Bath Bomb Recipe



  1. Mix all the dry ingredients (baking soda, citric acid, salt, and cornstarch) together in a large bowl until combined.
  2. Combine all the wet ingredients (oil, and water) in a small bowl and stir well. Add essential oils if using.
  3. Add the wet ingredients to the dry ingredients a few drops at a time. Mix well with hands or a spoon (if you have sensitive skin, it’s a good idea to wear gloves). If the mixture starts to fizz as you’re adding in the wet ingredients, just slow it down a bit, and ensure you’re only adding a tiny amount at a time. Add the powdered dried herbs if using.
  4. Once done, the mixture should hold together when squeezed without crumbling. You may need to add slightly more water if it hasn’t reached this consistency yet. Using a spray bottle with the extra water can help to evenly add it to the mixture.
  5. Quickly push mixture into moulds, muffin tins or any other container of your choosing. Press in firmly (make sure it’s really packed down) and leave at least 24-48 hours or until it’s hardened. It may expand a little which is completely normal. You can push it down into the mould a few times while it’s drying to keep it from expanding too much. Using the metal moulds will produce a stronger and more professional-looking bath bomb.
  6. Once dry, remove them from the moulds and store in an airtight container or bag. It is recommended that you use them 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.
