DIY Lavender Bath Bombs

Bath bombs are not only fun to use but super simple to make. They literally take about 10-20 minutes and afterward need a day to harden up. After that time they can be used and gifted immediately.

Tips for Making Bath Bombs at Home

If you are new to making bath bombs at home make sure to swing over and read all of our tips and tricks for making bath bombs at home before you get started.

Making bath bombs at home can seem like a daunting task, but I promise you it is super simple! Here are a couple of our favorite problem solving hacks that will make the bath bomb making process easier.

When it comes to bath bomb molds, they aren’t all made equal. While metal bath bomb molds are popular, I personally prefer silicone molds. They are a whole lot easier to pop the bath bomb out of plus easy to clean and store.

If you choose to use a metal bath bomb mold, put the bath bomb together side by side. If you attempt to mash the bath bomb mold top to bottom instead of side to side it will make getting the bath bomb out in one piece a bit harder.

Mixing ingredients also matters. I used to be one to just throw everything in and mix it all at once…then struggle with crumbly bath bombs. To avoid this, mix the wet ingredients together really well first. Then add the citric acid. This way you aren’t scrambling to beat the fizz.

And lastly, it is always a good idea to let your bath bomb sit in the mold overnight to dry.

After you have made your bath bombs, protect them from humidity by storing them in an airtight container.

Prep Time 15 minutes
Active Time 20 minutes
Total Time 35 minutes
Difficulty Easy
Estimated Cost $10


  • 2 cups baking soda
  • 1 cup citric acid
  • 1/2 cup cornstarch
  • 1/4 cup cream of tartar
  • 1/4 cup coconut oil (melted or solid. Both work!)
  • 1 tablespoon polysorbate 80
  • 20 drops of Lavender essential oils
  • Purple cosmetic glitter
  • 1-3 drops purple gel food coloring


  • Bath bomb molds
  • Spray bottle filled with rubbing alcohol
  • 1 large mixing bowl
  • 1 small bowl


  1. In a large mixing bowl, add the baking soda, citric acid, cornstarch, and cream of tartar. Whisk dry ingredients together.
  2. In a large mixing bowl, add the baking soda, citric acid, cornstarch, and cream of tartar. Whisk dry ingredients together.
  3. Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub.
  4. Add the lavender essential oi. This oil has been known to ease insomnia, relieve stress and anxiety, and has a calming and relaxing effect.
  5. Add the gel coloring, 1 drop at a time and mix after each drop until desired color is achieved.
  6. Next add the glitter. You can add as much or as little as you like.
  7. Mix the ingredients together. I use my hands to break down any lumps and make sure everything is really mixed in there. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand.
  8. Take one round mold and fill each side with the mixture until it is a bit over-flowing. Press both sides together, using a twisting/grinding motion to get rid of any excess mixture. Gently tap each side and carefully remove the bomb.
  9. As you progress through making the bath bombs, you may need to spray the mixture with the rubbing alcohol to moisten it, so the remaining bombs bind together.  Allow the bath bombs to dry a minimum of 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the final stage…the bombing of the water!
