DIY Bath Bombs with Epsom Salt

This is a fun twist on the classic DIY bath bombs recipe.

If you’ve never made your own bath bombs before, I can highly recommend it! DIY bath bombs are a lot easier to make than you’d expect, and you can customize them with your own, scents and colors.

Just like I did with this recipe. Instead of coloring the mixture, I colored the salts. The effect turned out even better than I could have imagined!

Choose your favorite color (Pink or blue for a baby shower? Red and green for Christmas?). Add your favorite essential oils and you have the perfect homemade gift.

Or keep them all for yourself. Because these DIY bath bombs are the perfect relaxing spa treat!

This recipe makes about 1 giant bath bomb (LUSH size) or about 3 medium sized ones. You can easily double or triple the ingredients to make more.

How to make DIY Bath Bombs with Epsom salt:

What I used:

  • 3 tbsp. Epsom salt (or coarse sea salt) – Get it here
  • 1/2 cup baking soda – Get it here
  • 1/4 cup cornstarch or arrowroot powder – Get it here
  • 1/4 cup citric acid – Get it here
  • 1 tbsp coconut oil – Get it here
  • spraying bottle with witch hazel or water – Get it here
  • liquid food or soap coloring – Get it here
  • essential oils (optional) – Get it here

Iโ€™m part of the Amazon affiliate program so I get a small commission when you buy something via these links. For me itโ€™s a win-win and I spend that money to make more bath bomb tutorials for you ๐Ÿ™‚ But feel free to Google the ingredients to find your own or buy them from local vendors in your area!

    Easy Epsom Salt Bath Bombs  DIY by The Makeup Dummy

    1. Color your salts

    Divide 3 tablespoons of Epsom salt between 2 bowls. Add one drop of food or soap coloring to one bowl and add a drop of another color to the other. Add more drops for a more intense color. Stir to evenly distribute the color over the salts.

    Let the salts sit while they soak up the dye.

    Divide the salts over more batches if you want to use more colors.

    2. Combine your dry ingredients

    Put the baking soda, cornstarch and citric acid in a large mixing bowl. Whisk together with a spoon or fork.

    This would also be the time to add your essential oils. I used 6 drops of ylang-ylang and 6 drops of lavender.

    Lavender is a great choice for its relaxing properties and ylang-ylang has a beautifully sweet scent.

    3. Add the coconut oil

    Add 1 heaping tablespoon of coconut oil to your dry mixture. Mix all the ingredients together and make sure to smooth out all the lumps.

    If you want you can melt the coconut oil first. This will make it easier to mix the oil with the rest of the ingredients.

    If for some reason you prefer to not use coconut oil (for example if you’re allergic), you swap it with another carrier oil, like olive oil or almond oil.

    4. Spritz with witch hazel

    Take a handful of the mixture and squeeze it together with your fingers in the palm of your hand. The powder should clump together.

    If it doesn’t you can spritz it lightly with some water (or witch hazel) in a spraying bottle.

    Stir well between each spritz and make sure the mixture doesn’t start to fizz in the bowl! Check regularly to see if the mixture clumps together.

    Once the mixture looks like damp sand, it’s ready.

    5. Create your DIY bath bombs

    Add the colored salts to the batch. Carefully stir the salts into the mixture.

    I put a few salts at the bottom of my mold because, well, it looks pretty! Fill your mold one spoonful at a time. Press the mixture down firmly after each scoop.

    Let your mold sit for a few hours or – if you can wait long enough – overnight. Carefully take the bath bomb out of its mold and wrap as a gift or keep for yourself!

    [recipe title=”DIY Bath Bombs with Epsom Salt” difficulty=”easy”]


    Ingredients:


    3 tbsp. Epsom salt (or coarse sea salt)
    1/2 cup baking soda
    1/4 cup cornstarch or arrowroot powder
    1/4 cup citric acid

    1 tbsp coconut oil
    spraying bottle with witch hazel
    liquid food or soap coloring
    essential oils (optional)

    Instructions:

    Step 1:

    Divide the epsom salt between 2 bowls. Add one drop of food or soap coloring to each bowl and stir well to evenly distribute the color. Let the salts sit while they soak up the dye.

    Step 2:

    Combine the baking soda, corn starch and citric acid in a large mixing bowl. Whisk together with a spoon. Add a few drops of essential oil while you keep stirring.

    Step 3:

    Add the (melted) coconut oil to your dry mixture. Mix all the ingredients together and make sure to smooth out all the lumps.

    Step 4:

    Take a handful of mixture and squeeze it in the palm of your hand. Spray the mixture with some witch hazel until it clumps together. Stir well between each spritz!

    Step 5:

    Add the colored salts to the batch and carefully mix together. You can keep a few teaspoons of salt and put them at the bottom of your mold.

    Press the mixture down firmly as you fill your mold. Let it sit for a few hours. Carefully take the bath bomb out of its mold.

    Enjoy!

          Excuse me, I was just wondering if the food colouring stains your body or the bath tub and if this recipe is alright for sensitive skin. Doesn`t food colouring stain so if could stain on your body or bath tub. Please say you have experimented it because I want to use this recipe to make a bath bomb for my sister and she has very sensitive skin. If this recipe is not okay for sensitive skin, please reply to me which recipe is alright for sensitive skin. Thank you so much!
          Your bath bombs look radiant though!

        Hi Kathy! Make sure to really press the mixture down firmly with your fingertips as you fill up your mold. If the mixture feels damp still it’s also possible you’ve used a little too much oil or water. Hope this helps!

            Hi Wendy, you can also use melted coconut oil. Just make sure you add it teaspoon by teaspoon. The liquid oil can start to react with the citric acid in the bowl. You can also semi melt it so it’s softer to mix. Whatever works for you ๐Ÿ™‚

      It’s fun to go to a thrift store and get your molds. I happened upon a mini metal owl cake mold and they are so cute. I spray a little coconut oil into the molds to get them to come out easier. Not too much, though! I love this recipe. It might just be my favorite and I’ve made many varieties.
