Homemade bath bombs are all the rage these days. They are so easy to DIY and there are a ton of different bath bomb recipes out there. I love how easy it is to personalize your bath fizzies’ scent with essential oils. Some of my favorites to use include Lavender (Relaxation) and Peppermint (Pick-Me-Up).

I have been on a Pink Himalayan salt kick ever since I learned about how good it is for you. This pretty pink salt is one of the purest salts on Earth and is high in mineral content. The fine-grained Pink Himalayan salt is good to use for bath bombs because it dissolves quicker than the larger sized salt crystals.
If you don’t have any Pink Himalayan salt at home, you can substitute another type of salt. Epsom Salts work great in this recipe, too. The main thing to remember when you make bath bombs is to use a 2:1:1 ratio of the main ingredients (Baking Soda, Salts, Citric Acid).
Heart-Shaped Bath Bombs
Of course, you can mold your bath bombs into any shape you like. These are heart-shaped bath bombs I made to use as Teacher Gifts for Valentine’s Day. I used Wilton heart shaped cookie cutters to make them in a couple different sizes. Besides cookie cutters, you can also use things like muffin tins or silicone molds to shape your bath fizzies. I line a baking sheet with waxed paper to give my bath bombs a place to dry. I let them air dry for about 24 hours until they are completely dry. Then I store them in an airtight container.
How to make bath bombs – ingredients.
I suggest experimenting with this smaller-sized batch. If you want to make a bigger batch, simply double the ingredients. For even bigger batches, remember to use the 2:1:1 ratio of main ingredients and add essential oils/food coloring as desired. I purchased a large bag of Pink Himalayan Salts and Citric Acid on Amazon. Some people say you can find Citric Acid with canning supplies at the store – but I have never found it there. Witch Hazel can be found in most grocery and drug stores. I used Majestic Pure Peppermint Essential Oil, also available on Amazon. Their peppermint EO has a wonderful fragrance perfect for scenting bath bombs.
- 1/2 cup baking soda
- 1/4 cup Pink Himalayan Salts (fine grain)
- 1/4 cup citric acid
- 1/2 tsp Essential Oil (I used Peppermint)
- 30+ drops red food coloring (optional if you want pink colored Bath Bombs)
- 1 tsp Witch Hazel (possibly a little more if needed)
1. Stir baking soda, salt and citric acid together in a mixing bowl.
2. In a separate, small cup, combine the Witch Hazel, Food Coloring and Essential Oil. (It’s okay that these ingredients don’t dissolve into each other. Just get the liquids all into one place for fast work in Step 3.)
3. Add a drop or two of the liquid ingredients from Step 2 to the dry ingredients and stir it in, trying to avoid letting the citric acid get too fizzy. It’s OK if it fizzes a little – it will do that. Continue adding the liquid a drop or two at a time and stirring. I drop, stir, drop, stir, drop stir, etc.
IMPORTANT TIP: You want to avoid making this mixture too wet. You want the salt mixture to be able to stick together without crumbling. Once you get to that consistency, stop adding liquid. You may need to make another batch of Witch Hazel/food coloring/essential oil to get to that point. Or you may not. If the mixture crumbles, add a little more. Just a drop or two at a time. Take it slow until you get the hang of it.
If the mixture feels wet, sticky or continues to fizz and/or puffs up, you have added too much moisture. You can salvage a “too wet” batch by adding more baking soda/salt/citric acid in the 2:1:1 ration.
4. Once the mixture is at that perfect point of being able to stick together without crumbling, it is ready to be put in the mold. You can use muffin tins, silicone molds or even cookie cutters. I have used all of those and the end result is the same. Basically, you’ll fill the mold (or cookie cutter placed on the baking sheet) with the bath bomb mixture. Allow it to set for about a minute, then carefully push it out of the mold (or lift up on the cookie cutter). The bath bomb should retain its shape without crumbling.
5. Put bath bombs in a dry place and allow them to air dry completely. I usually let mine sit out 24 hours.
6. Store bath bombs in an air tight container until ready to use.
Bath bombs are fun to make for yourself or to give as homemade gifts. And they aren’t just for grown-ups – my kids love to toss bath bombs into the water and watch them fizz. It’s hard to limit them to just ONE per bath! They’d go through my whole bath bomb arsenal in one bathtime if I wasn’t there to stop them.
These are really not hard to make once you get the feel for how wet/dry the mixture needs to be. And is is definitely cheaper to make your own bath bombs at home than buying at the store.
