DIY Bath Bomb Recipe for Beginners that Really Work!

Search DIY Bath Bomb Recipe and you're sure to come across multitudes of recipes; however, not all of them can work in a hot, humid, climate like the Philippines because bath bomb recipes are sensitive to the level of moisture in the air. I've tried and tested a ton of DIY Bath Bomb Recipes online and found one that works for me. I've tweaked it over the years and sharing my basic bath bomb recipe below!

Basic Bath Bomb Recipe for Beginners

My bath bomb recipe is quite simple. All you need are the following:

  • Half cup baking soda
  • a quarter cup cornstarch
  • a quarter cup citric acid granules
  • a quarter cup 'total' of Epsom salt and Himalayan pink salt (or just choose between the two)
  • a teaspoon to 2 teaspoons of additives such as kaolin clay, activated charcoal, or powder colorant like mica (I called them additive because you can omit then and your DIY bath bomb recipe will still be fine)
  • a teaspoon and a half 'total' of fragrance oils and essentials oils of your choice (I used my fave combo of ylang-ylang, orange, and vanilla)
  • a teaspoon 'each' of rose water, coconut oil, and witch hazel leaf extract
  • a drop or two of food color

Note that you have measure everything as exactly as possible because extra fluids can cause your citric acid and baking soda to be activated prematurely. 

Combine your dry ingredients and wet ingredients separately.

Then gradually add the wet ingredients to the dry ingredients while stirring vigorously.

I don't have photos for these steps because you really have to do the mixing for DIY bath bombs really fast.

You'll end up with a coarse sand-like mixture.

Prepare your molds. I just used ramekins because they are all I have when I made these bath bombs. My silicone molds were sitting in the sink lels! I've added a bit of mica powder to get a glitter effect. 

Pour over your DIY bath bomb mixture over your molds.

Pack the mixture in with a spoon  (or anything, really!)

The DIY bath bomb mixture has to be really packed in tightly so you can take it out of the mold without crumbling.

To take them out of the mold, turn your mold over and lightly tap.

Your bath bombs should fall right off!

Here are a few I've already made just chillin on my table drying out a bit (just 2-3 hours and then transfer them to air-tight containers).

I am ready to test my basic bath bomb!

And it worked!

no, really, watch the video :)

These bath bombs will stay good for up to a month in an air-tight container.

Side note: the activated charcoal is a bad idea because although I only added a quarter of a teaspoon for color, it leaves a residue. Better stick to using food color!

Have you tried making your own bath bomb? I think not using water is what made this basic bath bomb recipe of mine a winner because I live in a hot, humid place. The recipes that add water either fizz or crumble on me. Trust me, I've been making my own bath bombs since 2012!
