Transform Your Tub Into a Spa With These Fizzy, Floral DIY Bath Bombs

If you love bath bombs, you better read this. And if you don’t know what we’re talking about, this might change your life (or at least your bath).

Bath bombs are essentially spheres packed with ingredients that fizz when dropped into bathwater—you get foaminess, fragrance from essential oils, and sometimes even a little color. Slipping into pink-hued, floral-scented bath in your own tub feels very spa-like, and we’re not mad about that.

Considering some bath bomb products on the market are made with potential skin irritants like sulfates, limonene, and linalool, why not make your own? The process is relatively easy, and you can control what goes inside, and use all-natural ingredients. Once you stock up on these goods, you can make So. Many. Bath bombs. Very economical (and also lucky for your friends—drop a few in a glass jar for the ideal DIY gift).

Here’s the full recipe, and watch the video to follow along as we make a batch.

Geranium Fizzy Bath Bombs

Ingredients

1 cup baking soda
½ cup cornstarch
½ cup citric acid
½ cup Epsom salt
2 teaspoons water
2 teaspoons geranium essential oil (or other essential oil of your choice)
2 ½ teaspoons almond or olive oil
2 to 3 drops natural food coloring (optional)

Instructions

In a medium bowl, whisk together baking soda, cornstarch, citric acid, and Epsom salt. In a separate small bowl, whisk together water, geranium oil, almond or olive oil, and food coloring, if using.

Gradually whisk liquid into dry mixture. Slow down if it starts to foam. Once it sticks together like damp sand, it’s ready.

Pack mixture tightly into silicone molds (we used floral shapes). Set out to dry at room temperature 8 hours or overnight.

Remove from mold and store in an airtight container until ready to use.

When you’re ready for a soak, drop 1 or 2 bath bombs into the water before you hop in. Then sit back, relax, and smell the geraniums.
