How to Make Your Own Bath Bombs - DIY Bath Bombs

Bath bombs are kind of an obsession for me. They’re packed with essential oils for a fragrant aromatherapy experience not to mention all of the skin loving ingredients like baking soda and oils that are inside. Did I mention how fun they are? There is literally nothing not to love about bath bombs, and making your own bath bombs means you can customize all the goodness that goes in.

Love lavender and lemon? Sweet, add it! Want a bath bomb with sweet almond oil instead of coconut oil? Switch that baby out!

To Make Your Own Bath Bombs You’ll Need

1 cup baking soda

1/2 cup Epsom salt

1/2 cup corn starch

1/2 cup citric acid

2 1/2 tablespoons coconut oil, sweet almond oil, or grapeseed oil

1-2 tsp essential oil

Note: use about 1/4 of that if making bath bombs for kids. Never use essential oils in bath or diffusers around babies younger than 3 months old.

4-6 drops food coloring (optional)

1 tablespoon water

How to Make Your Own Bath Bombs

In a large glass bowl, whisk together all of your dry ingredients until combined.

In a separate glass bowl, briskly whisk together wet ingredients.

Slowly (very slowly) add your wet ingredients to your bowl of dry ingredients, whisking the dry mixture quickly to combine. You’re trying to add the liquid to the dry mixture slow enough to prevent a major reaction between your liquids and the citric acid in your bath bomb mixture. You want to save that for your bath later!

Continue slowly pouring in your wet mixture until it becomes like damp sand. If your mixture is still too dry, try adding a few drops of water at a time until you get the right consistency. You should be able to press a ball together without it falling apart.

Once your mixture is like damp sand, press it into molds. You can use silicone molds specially made for bath bombs or use a cupcake tin. Silicone molds or bakeware won’t need to be greased first, but make sure to lightly rub your oil in the inside of any metal or glass molds to make it easier to pop out your bath bombs later.

Allow your bath bombs 5-10 minutes to dry, then gently remove them from the molds. Set aside to completely dry for 24 hours.

Once dry, store in a clean, water proof area (ziplock bags and/or cling wrap are great for this) until you’re ready to throw one into a tub and enjoy the fizzy magic you just created!


Quick Tips for Bath Bombs that are Totally Extra

  • Add up to a tablespoon of glitter! Just make sure it’s biodegradable and not regular craft glitter. Your tub (and the ocean) will thank you.
  • Layer bath bomb colors by adding the coloring last after the rest of the mixture has come together. Add coloring to separate handfuls of your bath bomb mixture, mix, and layer into your molds.
  • Add dried flowers or herbs to the bottom of your mold and press your bath bomb mixture around it.

      I’ve made them with and without corn starch, and there isn’t much difference to them texture wise. I prefer the corn starch ones because it adds a nice softening effect to the bath water, and I find they hold together a little better. Corn starch seems to be a good binder.

      You can totally do both! I love Lush bath bombs, but I’m really sensitive to smells, so I don’t like to buy them online. If I can’t make the trip out to the mall to their store, I’ll make my own. Or if I want a specific scent like citrus lavender for my mood that day.
