As much fun as mani bombs are, I’m a total bath addict and am using bath bombs constantly! Today I’m going to show you how to make your own beautiful rose bath bombs! Check out my first post to see photos of the basics of the process.
What you’ll need
Makes about 2.5 bath bombs- I usually use the leftover mix in small square trays for mani bombs! You can also double the mixture to make more at one time.
- 1 cup baking soda
- 1/2 cup cornstarch
- 1/2 cup citric acid (I have trouble finding this locally so I purchased some from Amazon)
- 1/2 cup salts (I used 1/4 cup of Epsom Salts and 1/4 cup Sea Salt)
- 2 teaspoons essential oil (your choice, optional- I used Rose)
- 2-4 tablespoons oil of your preference (here I used Coconut oil, which I melted first. I usually start with 2 tablespoons of oil and add more into the mixture if it’s not fully compacting together in the circular molds)
- A few drops of food coloring (optional)
- Spray bottle filled with water
- Silicone or candy mold of your choice (I used a plastic ornament)
- Dried rose petals (optional)
- Parchment paper
1. First, mix all of your dry ingredients (baking soda, cornstarch, citric acid and salts) together in a bowl using a whisk.
2. In a small separate bowl, combine your wet ingredients (essential oil and your chosen oils- if you want your bath bombs to be all one color, you can add your food coloring here, otherwise save it for later).
3. Start mixing your dry ingredients with your wet ingredients. Mix in just a little of the wet at a time until it is all combined.
4. Test the texture by squeezing some of the mixture in your hands- it should feel like wet sand and hold it’s shape after you squeeze it but still be dry enough that if you press down on it, the shape breaks. This is where the spray bottle with water comes in- after you initially mix the ingredients together, if the consistency isn’t right, spray it with a little water. Do this slowly, I usually do between 1-3 spritzes, test the consistency again and then more as needed. If you add too much water, it will activate the citric acid and won’t react properly.
5. Once the mixture is perfect, separate half of it into another bowl and add a few drops of food coloring, mixing until you get the desired shade.
6. Start packing your molds. The basic way to make a typical bath bomb is to overfill each side of the mold and then press them together, twisting and turning slightly until both sides of the ornament meet and the mixture is compacted.
7. (Optional) Dried rose petals will add a fancy and beautiful look to the bath bomb. On one side of the ornament, first place some roses into the top area before adding any mixture, then fill that side up.
8. Once full, hollow out a small area and place more rose petals into it, then add a bit more mixture on top and overfill the second half of the bath bomb, finishing up as normal from Step 6.
9. Place a towel onto a flat surface in a dry area and put a piece of parchment paper on top of it. This helps the bottom of the bomb not flatten out if it is a rounded shape.
10. Gently remove one half of the ornament (tap the plastic gently with a spoon first), then the second and place it onto the parchment paper.
8. Wait 24 hours for the bombs to dry fully, then package for gifts or use for yourself! You can wrap saran wrap around any that you want to keep fresh for awhile. To use, just fill your bathtub up with warm water, drop it in and let it fizz!
Doesn’t fizz very much when used– You probably added too much water when making the mixture, try it again with a little less.
Parts of the design sets in the mold but it won’t all fully stick together (usually with large circular bath bombs)– Try adding a little bit more oil into the mixture.
Design keeps cracking and breaking when removing from the mold– First, re-check that your mixture is the correct wet-sand-like consistency, then try leaving the mixture to dry in the mold for a few hours or overnight instead of removing right away.
Falls apart when picked up after 24 hours– It may not have dried and set fully, try leaving it for 2 days instead and if it’s still falling apart, use a little more water in the mixture.
Sets and holds it’s form after 24 hours but has cracks– You used a bit too much moisture which made it react and slightly expand. Reduce it slightly the next time.
Humidity can make it difficult for your bath bomb to fully harden, too! Make sure you’re making and leaving it in as cool and dry an area as possible and try waiting an additional 24 hours if it is not hardening! When we have had 90+ degree humid weather my mani bombs have been okay for the most part but a few of my bath bombs which hardened overnight went soft due to the humidity so be careful!
These turned out super pretty and smell amazing! I made them as gifts but I might end up keeping them for myself, oops. As always, let me know what you think about these DIY posts & be sure to tag me on social media if you try this out!
