Bath Bombs and Shower Fizzies: Part 2

Part 2 of our bath bombs and shower fizzies series is here! Join me for another recipe that molded well, stayed together, and produced an awesome fizz and aroma. If you are looking for some hostess, girlfriend or self-pampering gifts, these are a such a wonderful place to start.

If you would like another recipe, I shared our Sweet Shoppe Lemon Drop bath bomband our LUSH-inspired Lavender Dream bath bomb.

Update: Whew, I’ve made a LOT of bath bombs over the years. Check out these amazing blends and processes for your own DIY bath bomb recipes to WOW!

I’ve tested this mix repeatedly: this one adds a small bit of oil and Epsom salts. Before we get to the recipe, I wanted to mention that I provide detailed instructions for making bath bombs, as well as a plethora of recipes and tips on my Exclusive Content for Email Subscribers page.

There is just too much to put into a post, so I’ve put the majority of the tips there. If you are new to making bath fizzies, consider making it your starting point.

Shower Fizzies Versus Bath Bombs

If you’d like to make shower fizzies (shower steamers) with this recipe, I urge you to read instead our shower fizzies recipe here. I don’t want you to waste time, money, or any of your expensive essential oils!

Supplies for Peppermint Bath Bombs

The supplies for this Epsom salt bath bomb are:

• 1 cup baking soda
• 1/2 cup citric acid
• 1/2 cup cornstarch
• 3 tbsp Epsom salt
• 2 tsp sweet almond oil (can use coconut, olive, jojoba or any other body-safe oil)
• 3/4 tsp room temperature water
• 15-20 drops essential oil (can be a combination of oils); for this recipe, I used peppermint oil only.**
• a glass (or metal) bowl
• coloring, optional – I used a rose pink gel colorant from the craft store (Wilton brand), but using red or ‘Christmas red’ produces a brighter pink.
• witch hazel (a small amount in a spray bottle)

Instructions for Our No-Fail Bath Bomb Recipe

1. Mix the dry ingredients together (baking soda, citric acid, cornstarch, and salt).
2. Mix the essential oil, almond oil, water, and colorant in a small bowl.
3. Pour the wet mixture into the dry mixture and use your hands to incorporate the oils and color very well.
4. Pack it firmly into hard molds (avoid soft silicone molds or anything that has too much give).

Depending on the time of year and level of humidity, you could have problems with this drying out into a crumbly mess.

If Your Mix is Crumbly…

If your peppermint bath bomb mixture results is a crumbly mess after you tried to mold it, dump the powder back into a large bowl. Use your spray bottle to add the witch hazel to the top of the mix.

• large spray bottle: spray two to three times and then mix it for a solid minute or two before spraying again.
• small spray bottles (travel size): use 5-8 sprays and then mix. Mix it well, using your gloved hands to get the witch hazel off the sides of the bowl.

When it sticks together without crumbling (photo below)you can begin packing it into your mold. Push it down with your thumb or a tamper, just get it in there very tightly.

How to Mold a Bath Bomb

If you are using a full circle mold, stuff the peppermint bath bombs mix in, pack it down, and add a heaping amount to the top. Squish the two pieces together until the mold is a sphere again, and leave it for about a minute before you remove it from the mold gently. Drape a towel over a muffin tin and place the bath bomb on top of the towel.

Note: this recipe does well if you leave it in a bath bomb mold or a silicone mold for a few hours or overnight before unmolding.

If you are using a half circle mold, pack it in and rest it in a muffin tin, flat side up for no less than overnight. If you are using a hard silicone mold (not soft), leave it 24 hoursbefore attempting to remove.

How to Harden Bath Bombs

Leaving the mix in the mold for 12-24 hours, then leaving them to dry on the counter for 24-48 is sound advice.

This works well for the half ornaments and shapes. I made full sphere bath bombs with this recipe, but this one turned out best using the half ornament shape. I recommend leaving these in a hardmold for 24 hours and not using intricate shapes with this recipe.

DIY Bath Bomb Gift

Bath bombs are a great gift to give or receive – they always smell so nice and can be used for a mental break.

If you (or your gift recipient) isn’t into taking baths, you can do what I do on occasion: change up the mix a bit (see our Shower Fizzies versus Bath Bombs Recipes) and gift shower steamers.

I have named this one, “Peppermint Schmepermint,” and created a little wrap to jazz it up a bit. I have included a free printable!

How to Store Bath Bombs (Long-Term)

One more thing before we’re through here – go ahead and heat shrink these into a cello bag. Doing so makes them look nice but it’s not just about the look. Keeping bath bombs and shower fizzies in an airtight packaging helps to increase their shelf life.

It’s not hard to do and you don’t need any special equipment! I include instructions in my exclusive content section for packaging and heat shrinking these bath bombs and shower fizzies. For access, just sign up to the free newsletter.
