While a glass of wine, good book, or a plethora of bubbles can be the perfect addition to a hot bath, a more colorful and exciting option can be the bath bomb. Often molded into a small sphere that fits into the palm of your hand (although you can find them in fun shapes, too!) the bath bomb will instantly begin to fizz and disintegrate once it hits the water. Unleashing a pleasant aroma and filling your bath with a pop of color (and in some cases, a little sparkle or full rainbow), a bath bomb can add a little zest and fun to a soothing self-care ritual. Bath bombs often range from 5-15 dollars each, but you don't have to spend your hard-earned money on this delightful indulgence if you choose to make your own at home. In fact, the process is pretty simple and can be a relaxing and creative activity, as you can customize them to the scents and colors you like best. With this basic recipe, creating your own bath bomb should be pretty easy, and you'll be sudsing in a colorful, scented bath in no time.
Almost all bath bomb recipes call for the same ingredients and measurements, with a few occasional exceptions. The key to great bath bombs is citric acid, which isn't hard to find online. If you'd rather not shop online and prefer the IRL approach, you may be able to purchase citric acid from your local pharmacy.
These bath bombs make perfect gifts (for others or yourself— self care is important!) You can put both large or small ones in cellophane gift bags like—the ones you'd typically buy for cookies—or stack smaller ones in a wide-mouth Mason jar. Make a few batches using different colors and add various essential oils for an array of scents if you'd like some variety.
Bath Bomb Recipe Ingredients and Materials
- 1 cup baking soda
- 1/2 cup citric acid
- 1/2 cup Epsom salt
- 1/2 cup cornstarch
- 3/4 tsp. water
- 2 tsp essential oil (lavender, eucalyptus, rose are all popular for the bath)
- 2 tsp oil (jojoba, sweet almond, coconut olive or even baby oil)
- A few drops of food coloring.
- A mold of your choice, such as regular or mini-muffin tins, candy pans, or round plastic molds specifically for bath bombs
- Optional: Dried flowers or sugar cake decorations, like flowers or stars
Bath Bomb Instructions
Step 1: With the exception of the citric acid, mix the dry ingredients in a large mixing bowl.
Step 2: Pour all of the liquid ingredients in a jar with a top. Close the jar and shake it vigorously.
Step 3: Pour the liquid mixture into the bowl of dry ingredients, and use your hands to combine and meld together. At this point, add the citric acid. You'll probably notice a slight fizzing reaction because of the citric acid. No need to panic, as this is totally normal.
The mixture should be a bit crumbly (similar to the consistency of wet beach sand). Whatever you do, don't add water at this stage, or the bath bomb will fizz prematurely and be ruined.
Step 4: Mash the mixture into your chosen molds very tightly. You may slightly overfill the molds and use a spoon or glass to press the mixture in as tightly as possible. Immediately loosen the bombs from their molds onto wax paper and let them dry overnight.
Step 4: Give the bath bombs a day or two to completely dry before using them or wrapping them up as gifts.
Step 5: Pop one in the bathtub, enjoy the burst of colors and fizz, and inhale the released aromas. Turn on some of your favorite music or podcast to accompany you while you soak, or simply slide into the bath and enjoy all of your hard work.
