Aren’t these homemade heart-shaped bath bombs adorable? It’s almost Valentine’s Day so this DIY recipe is perfect to make a special teacher’s gift, small gifts for your friends and family members, or anyone who needs some love and heart bath bombs in their life. Make up a batch of lush bath bombs to give yourself a luxurious treat — self-care is so important!
Bath bombs are hard-packed mixtures of dry ingredients which effervesce when wet. They are used to add essential oils, scent, bubbles, or color to bathwater. (source: Wikipedia)
So basically, when you need to slow down, enjoy a bath, release some stress, and relax your muscles, bath bombs are the perfect solution as a carrier for essential oils and aromatherapy.
Our heart-shaped bath bombs with essential oils can carry 15 drops of the essential oils of your choosing. We have some suggestions for bath bomb essential oil blends depending on what your needs are, but basically you can take your pick. Here are some great blends to try.
- 7 drops of lavender and 8 drops of peppermint would be a calming and stress-relieving blend for bed time.
- 7 drops of Bergamot and 8 drops of grapefruit essential oil would be uplifting.
- 7 drops of rosemary and 8 drops of lemongrass would be great for tension relief and muscle soothing.
Our Heart-Shaped Bath Bombs with Essential Oils use a large size mold with six cavities to make nice big bath bombs. You can, however, pick any size and shape you want. Any flexible silicone mold will work. Buy the mold we used for our heart-shaped bath bombs here by clicking on the image above.
Before making your heart-shaped bath bombs, mix your essential oils of choice into 2.5 tablespoons of witch hazel. Then proceed with the instructions in our recipe card below. Just know that when you add the witch hazel mixture to your other ingredients, it is going to fizz a little. That’s okay. That’s what makes the effervescence in your bath bombs happen.
We added plain Himalayan salt to the bottom of each mold to add a pretty pink touch to our heart-shaped bath bombs. You do not need both fine and large flake Himalayan salts. One or the other works fine. The fine grain on the top gives a shimmer to the top of the bombs whereas the larger flakes give a more textured appearance. You can see an example of each in the pictures.
Here’s an important tip when you are ready to fill the molds for your DIY bath bombs. The more thoroughly you press the mixture into the molds, the better your bath bombs will hold up for gift-giving and storage. Use a spatula to press the mixture firmly down into the mold. Spray a tiny bit of water over the mold (if needed) and press down again to ensure it is all combined and holding. It’s a fine balance of pressing and spraying water. Do not spray too much or the bombs will lose their fizz. You will just need a tiny bit of water to help them hold together.
The finished heart-shaped bath bombs can be placed in a jar or small bag for gift giving and storage. Sealing the bath bombs in a container will help prevent them from degrading in a moist environment. You can also wrap your bath bombs individually in cling wrap if you like, for an extra layer of protection.

DIY: Heart-Shaped Bath Bombs with Essential Oils
- 1 cup baking soda
- 1/2 cup + 1 tablespoon citric acid
- 1/2 cup Epsom salts
- ¾ cup + 2 tablespoons cornstarch
- ¼ cup fine grain Himalayan Pink Salt
- 2.5 tablespoons witch hazel
- 15 drops of essential oils (preference)*
- 1/8 cup Large Himalayan Pink Salt for topping * (or more fine grain)
- Mini spray bottle with water
In a large bowl, combine the first five ingredients and mix well.
If using essential oils, combine them with the witch hazel.
Add the witch hazel into the large bowl (it will fizz, that’s okay!) and mix until mostly combined. The mixture will look only a bit wet (this is normal).
In the bottom of your molds, portion out the large pink salt.
Fill each mold halfway with the bath bomb mixture. Use a spatula to press the mixture firmly down into the mold. The better you do this, the more they will hold together. Spray a tiny bit of water over the mold (if needed) and press down again to ensure it is all combined and holding.
Portion out the remaining mixture to fill the molds and repeat the process of pressing down, spraying with water, etc.
It’s a fine balance of pressing and spraying water. Do not spray too much or the bombs will lose their fizz. Just a tiny bit to help them hold.
Let sit on the counter for 24 hours to set.
Pop out of the molds and use!
7 large heart-shaped bombs (mold depending).
You do not need both fine and large flake Himalayan salts. One or the other works fine. The fine grain on the top gives a shimmer to the top of the bombs whereas the larger flakes give a more textured appearance.
Use any essential oils you like and customize them for the person using the bombs. Lavender is very calming, citrus blends are very mood elevating. Use your favorites.
