Had a long day? Here’s a simple, budget-friendly way to treat yourself at home. These DIY bath bombs are easy to make with pantry staples and essential oils, and they bring a spa-like touch to any bath.
Life can be stressful for everyone in the family. I’ve shared ways to ease tension for kids and parents alike, and taking a soothing bath is one of my favorite quick resets. Adding a bath bomb makes that soak feel luxurious without leaving the house.
Store-bought bath bombs can be expensive, but the good news is they’re simple to make at home. This recipe uses lavender and chamomile essential oils for a calming aroma, though you can swap in any oils you prefer.
Make a double batch to keep some for yourself and share the rest as thoughtful, handmade gifts. They’re fast to prepare, customizable, and great for pampering kids or grown-ups.
Supplies
Most of these ingredients are likely already in your pantry or cupboard.
- 1 cup baking soda (bicarbonate of soda)
- 1/2 cup citric acid
- 1/2 cup Epsom salt
- 1 tsp water
- 3 tsp olive oil
- 15 drops lavender essential oil
- 15 drops roman chamomile essential oil
- Food coloring (a few drops)
- Silicone molds (flower shapes, cupcake molds, or similar)
- Jar for storage
- Whisk
Note: Use any essential oil combination you like. A little goes a long way.
How to make DIY bath bombs
This project is straightforward and fun. Follow the steps below to make several bath bombs for gifts or personal use.
Step 1
In a large bowl, combine the dry ingredients: baking soda, Epsom salt, and citric acid.
Step 2
Add 3 teaspoons of olive oil and 1 teaspoon of water to the bowl. The mixture may fizz slightly when the water is added.
Step 3
Whisk the mixture well, then add the essential oils and whisk again until evenly distributed.
Tip: I used 15 drops each of lavender and chamomile for a relaxing scent. Feel free to substitute other oils to suit your preferences.
Step 4
Add about 3 drops of food coloring and stir until the color is blended and there are no clumps. The mixture should be just moist enough to hold together when pressed.
Step 5
Press the moist mixture firmly into your silicone molds, compacting it like sandcastles. Do this over a cookie sheet for easier cleanup. Gently tap the filled molds on the counter to release trapped air bubbles.
Allow the bath bombs to dry fully for 24–48 hours. Once dry, carefully pop them from the molds and they’re ready to use or gift.
Notes and tips
- This recipe can leave extra mix for a larger bath bomb if you use a bigger mold, like a silicone cupcake mold.
- Different molds will change how much mix you need. Adjust accordingly.
- Bath bombs can expand slightly while drying; press them back into the molds if needed. Dry them in a cool place to reduce expansion.
FAQs
Here are answers to common questions about homemade bath bombs.
