Soak Your Muscle Pain Away with Homemade Bath Bombs

As we are sheltering-in-place this time of year, I like a lot of people have more time to start exercising regularly. Anytime I start working out with a significant dedication, I deal with so much lactic acid buildup in my body that it starts to chip big holes in my commitment to exercising. I started looking at some Epsom salt soak recipes and stumbled on Epsom salt based homemade bath bombs that I wanted to try.

The bath bomb idea is perfect since they are perfectly portioned, and you can just throw in the water without measuring anything. I wanted to find the best recipe for both use and easy to make, and I had the perfect testers in my family – adults trying to get back into shape and college athlete kids that need recovery after a hard workout. Here is a review of the first one I tried.

Eucalyptus Epsom Salts Homemade Bath Bombs with Coconut Oil

For the first test, I got this recipe from this pin:

I really liked the look of the ingredients since I had all of them on hand: Epsom salts, baking soda, cream of tartar, and coconut oil. The recipe calls for Eucalyptus essential oils. Since I didn’t have essential oil on hand, I used a Eucalyptus infused Epsom salt that I bought from


Making them was super easy. I mixed all of the dry ingredients, measured out the coconut oil, melted the oil in the microwave (on 20-second intervals), and then mixed it with the dry ingredients.

After mixing everything together, I used a silicone muffin pan and packed the bath bomb mixture in with a spoon (pressing firmly with the back of the spoon to make sure it was very well packed in). It made four muffin size bombs exactly.

I let them dry overnight in the muffin pan.

They dissolved in the bath well. Both the adults and the college athletes in the family liked them, and we all felt better after using them for a soak.


They did crumble a bit. Getting the bath bombs out of the muffin pan wasn’t too hard since you could press them from below and push them out. The tops did crumble when I was trying to get them out and when I was placing them in the jar for storage, there was a lot of crumbling. The coconut oil did a moderate job of binding the dry ingredients together.

The oil made the tub slippery. The coconut oil did remain in the bathtub a bit, so it was slippery to get out or to use the next day for a shower. Putting in some of the floor stickers or mat in the tub to keep from slipping is a good idea.

Final Thoughts on this Homemade Bath Bomb Recipe

I really liked the recipe. It was inexpensive, easy to make, easy to use, and worked well. The only issue was the crumbling made a bit of a mess, and the oils potentially could be a hazard.
