How to make a bath bomb
Here are step by step photos and instructions to help you visualize how to build this project. Please scroll down to print the instructions!
- Combine baking soda, citric acid, Epsom saltand cornflour together in a medium bowl. Use a whisk or fork to stir together and remove any lumps. If adding dried flowers or herbs, add them to this step.
- In a small glass jar or bowl, whisk together the melted coconut oil and water.
- If coloring your bath bomb, add 1-2 drops Soap color Wet ingredients and stir.
- If adding essential oils, add 8-15 drops during this step.
- Slowly (and I mean slowly!) pour the wet mixture into the dry mixture, stirring as you go. If you see the mixture fizz or foam, you are adding liquid too quickly. Just add the wet mixture slowly.
- Once the wet ingredients have combined with the dry, take a small amount in your hand and squeeze it together. It should probably stick together in 1-2 pieces. If it’s still too powdery to hold together, slowly add a little more water and try squeezing it again.
Molding with 2-sided moulds
Pack each of your halves tightly Two sided ghat with the mixture until it thickens slightly. Press the mold pieces together, then gently remove one side of the mold. Place the bath bomb on the tray and let it dry before removing the other side (about an hour). Be gentle in the un-molding process!
Molding with silicone ice cube tray
Pack the bomb mixture tightly Silicone ice cube tray Slots, smooth and flat top. Let set for about 10 minutes and then carefully invert the tray and un-mold the bath bombs onto the baking sheet with a light tap on the top of each shape. As mentioned above, the key is to be gentle with the un-molding process!
Once your bath bombs are un-molded and on the baking sheet, they should dry for at least 8 hours or overnight.

Add 1-2 drops of 1 color to 1 wet mix and 1-2 drops of a different color to another wet mix. Follow steps 4-5 below and then fill 1 side 2 piece mold with one color, and fill the other side with the 2nd color and then proceed to step 6.
- If the bath bomb bursts while removing it from the mold, go back to step 6 and start the molding process again. If necessary, add some water to remix the ingredients.
- If your Epsom salts already have fragrance, you can skip adding the essential oils.
- If you are making as a gift, keep in mind that people may be sensitive or allergic to various ingredients.
Once the bath bomb is completely dry, store it glass jar. This makes a great gift!
