A while ago I posted some homemade bath bombs to social media. Since then I’ve had a few requests for a tutorial on how I made them so I thought I would put something together using my favourite example, Rose Oatmeal. This is a great DIY project for beginners!

Much like other DIY projects, the end result is that you’ll have bombs that are much less expensive than purchasing the finished product. This recipe doesn’t make too many, but I prefer making mine in smaller batches. Smaller batches allow you to make a few different scents if you’re making many to give away as gifts. Also if you are experimenting or just learning, it’s less wasteful if things don’t go exactly as planned.

I’ll jump right in, beginning with what you need, and go through the steps one at a time!

1. Gather all your tools and ingredients

You are going to need:

Ingredients 

  • 1/2 cup baking soda
  • 1/4 cup food grade citric acid
  • 1/4 cup epsom salt (I’ve also used sea salt as a substitute)
  • 2 tbsp coconut oil
  • Essential oils (optional)
  • Oatmeal flakes (optional)
  • Rose pedals (optional)

Tools

  • Bath bomb molds*
  • Medium mixing bowl
  • Whisk

* I’ve read that a meat baller works in place of bath bomb molds, but haven’t tried it myself

2. Mix together dry ingredients

Using the whisk, mix salt, baking soda, and citric acid in the medium sized bowl.

3. Melt and add coconut oil

You can melt your coconut oil (carefully) by placing it in a small bowl and setting it on top of a cup of hot water, stirring it until melted.

Once melted, add it to the dry mixture and stir until it starts to look like wet sand – or snow just because I’m Canadian.

4. Add essential oils

I added 30 drops of essential oils here. For this batch, I used tea tree oil, but there are no rules of course! Pick your favourite, or a combo of favourites, and add them in. You can also go without if you prefer scentless.

Once you have your oils in there, mix your creation some more until it’s well blended.

5. Decorate (optional)

Use a hand blender to grind up a handful of oatmeal flakes and rose pedals. Then put them in one half of your mould. Avoid creating a pile because the mixture needs something to stick to. Just make a small layer at the bottom.

6. Put them in the mould

Pack the moulds as tightly as possible and squish them together. Wait 3 minutes before removing. Don’t worry, you don’t need to stand there and hold them the whole time. I wrap mine with rubber bands so that I could walk away and do something else.

7. Unmould

Carefully take you new bath bombs from the moulds and place them on a soft towel to dry, but out of reach of children, pets, and curious spouses. Try to avoid moving them around and let them dry for 24 hours so that they have a lot of time to dry.

Note: after one hour, my boyfriend casually grabbed one on his way through the kitchen because he wanted to see how they turned out. My thinking is he may have given it a slight squeeze because he exclaimed something across the house about how solid they were. It lived and I laughed, but be sure to communicate with others not to touch 🙂 

Enjoy!

Hope you enjoyed my tutorial – and your own DIY bath bombs!
