Happy spring, everyone!
Today I wanted to share this bath bomb DIY that I made over the weekend. It’s super easy to make and also very fun to use. Not only do these make a wonderful addition to any Mother’s Day gift, they’re a great gift for a perfect addition to spa night and the explosion of scents is so delightful during a relaxing bath.
Making bath bombs at home is not only cost effective but also ensures that you know exactly what products go into your bath – it’s also very fun to choose your own colours and scents. If you’re making them for Valentine’s Day or Mother’s Day, you can create a whole gift around giving someone that much-needed spa feeling right at home or get everything you need to make them together!

Homemade bath bombs stored in KSP Spa Apothecary Jars to create the perfect spa look
Ingredients
- 8 oz Baking Soda
- 4 oz Epsom Salt
- 4 oz Corn Starch
- 3 Tsp Citric Acid
- 3 Tsp Coconut Oil
- Upper Canada Eucalyptus Essential Oil (4 – 5 drops)
- Upper Canada Lavender Essential Oil (4 – 5 drops)
- Soap Colouring (Food Colouring is ok too!)
Utensils required
- Assorted Mixing Bowls (we used the KSP Sorbet Bowls)
- Trudeau Ice Sphere Mold
- J.A. Henckels Classic Whisk
- KSP Spa Apothecary Jars
- KSP Measuring Spoons
Method
- Mix the baking soda, epsom salt, corn starch, and citric acid in a large bowl. Use a whisk or fork to make sure the mixture is clump-free.
- In a separate mixing bowl, combine the coconut oil, water and essential oils. If you’re planning to use multiple colours, separate the liquid into 2 bowls before adding soap colouring. Do the same for the dry ingredients.
- Ensure the liquids are completely combined and slowly with your measuring spoon, add the liquid into the dry ingredients being careful not to drown out the dry ingredients as this will activate the fizzing! Once you’ve added in all of your liquid, your final mixture should have the consistency of damp sand.
- Stuff the mixture into the sphere mold. You can either stuff one colour into the entire mold or mix and match multiple colours! For smaller bath bombs, you can also pack half of the mold and dry separately.
- Pop the molds into the fridge or leave in a cool damp place.
- After 24 hours, carefully pop the spheres out of the ice mold and voilà your very own bespoke bath bombs!
Benefits of eucalyptus oil
Known for its anti-bacterial benefits, eucalyptus oil has been used in Chinese medicine for centuries. It is highly effective in treating wounds, minor cuts, acne, boils, insect bites, skin infections and is very soothing to the skin.
Why we love lavender oil
The relaxing scent of lavender is great for eliminating stress and nervous tension. Lavender has also been known to relieve sores and pain, enhance blood circulation, and treat respiratory problems – the perfect addition to bath time!
