How to Make Lavender Bath Bombs

These step by step photos and instructions are here to help you visualize how to make this project. Please scroll down to simply print out the instructions!

Combine the baking soda, citric acid, Epsom salt, dried lavender, and cornstarch in a medium-sized bowl.
Use a whisk or fork to stir together and remove any lumps.
In a small glass jar or bowl, stir together melted coconut oil and water.
If coloring your bath bombs, add 8 drops of purple soap coloring to the wet ingredients and stir.
If adding essential oils, add 10 drops of lavender-scented oil to the wet ingredients.
Very slowly pour the wet mixture in with the dry mixture, whisking as you go. If you see the mixture fizz or foam, you may be adding the liquid too quickly. Slow down adding the wet mixture if so.
Once the wet and dry ingredients are combined, take a small amount in your hand and squeeze it together. It should stick together in maybe 1-2 pieces. If it’s still too powdery to hold together, slowly add a tiny bit more water and try squeezing it again.
This is optional, but we added dried lavender buds to the bottom of the molds before jumping into the next step. This is what gives your bath bombs a beautiful lavender topping!
Using a 2 inch 2-sided mold, tightly pack each half with the mixture until it’s overflowing just a little. Press the mold pieces together to further pack the mixture, then gently remove one side of the mold.
Place the bomb on a tray, mold side down, and allow to dry out before removing the other side (about an hour). The key here is being gentle in the un-molding process!
Once your bath bombs are un-molded and on a baking sheet, they should be left to dry for at minimum 8 hours or overnight. You want your bath bombs to be completely dry before wrapping them or placing in a container as moisture can activate the bath bombs. If you live in a humid area, allow 24 hours for drying time.

Expert Crafting Tips

You can add Bergamot, Sandalwood, or Patchouli essential oils to the mix if you’d like, these oils pair beautifully with lavender. Simply use half of whatever scent you want, and half lavender essential oil while making the bombs. Be careful not to add too much oil though!
As you see above, we did a batch of purple-colored bath bombs and a batch of white bombs. It’s best to do these as separate batches if you’re looking to do both as measuring can get tricky when dividing.
In case a bath bomb cracks while removing it from a mold, go back to step 7 and start the molding process again. If needed, add a tiny bit of water to remix ingredients.
If your Epsom salts already have a fragrance, you can skip adding the essential oils.
If giving as gifts, wrap your bath bombs in plastic wrap after completely dried and then wrap with tissue paper and a bow!
