We are obsessed with bath bombs over here and I am OK with that because I am also obsessed with making them.

Bath bombs are surprisingly simple to make and generally only require a few ingredients.

These tropical scented fruit bombs make the perfect bath bomb recipe for kids or gift for anyone on your list.

Made with lime, lemon, orange, tangerine, and spearmint essential oil, these bath bombs smell amazing and are very uplifting.

Adding a bath bomb like this one or my simple bath bomb recipe to your bath is a wonderful way to end a stressful day and help you relax before drifting off to sleep.

Tropical Essential Oil Blend

The best part about these fruity bath bombs is the scent. To achieve that fruity tropical aroma, we are going to use a bunch of citrus essential oils along with a touch of spearmint.

It took a few attempts to get the perfect combination of oils, but I think the blend below is the perfect tropical essential oil blend.

  • 5 drops lime essential oil
  • 4 drops lemon essential oil
  • 4 drops orange essential oil
  • 3 drops tangerine essential oil
  • 2 drops spearmint essential oil

These amounts are based on the recipe below. Adjust the drops accordingly if you half or double the recipe.

If making bath bombs for kids, you may want to decrease the amount of essential oils to dilute them further.

Citrus essential oils can help boost energy, uplift the mood, purify the air, and boost the immune system.

In addition, the spearmint essential oil adds a refreshing aroma and a revitalizing touch to your bath. Afterward, I like to use my homemade muscle rub for an extra indulgent self-care moment.

How to Make Tropical Bath Bombs

  1. Grease bath bomb molds with a small amount of coconut oil and set aside. This will greatly reduce the effort required to remove the dry bath bomb from the mold.
  2. Add all dry ingredients to a mixing bowl and stir well.  
  3. Add colors of choice by proportioning the mixed ingredients into small individual bowls and adding colors to each individual bowl.
  4. In a separate mixing bowl, combine wet ingredients and whisk together until well combined.
  5. Add essential oils in with the wet ingredients and whisk well.
  6. Combine wet and dry ingredients and mix well. 
  7. Pack the mixture into both sides of the bath bomb molds, then press the two halves together. Wipe the excess mixture off the sides and set it aside.
  8. Allow the molds to sit for 24-48 hours or until completely dry and then pop out of the molds.

NOTES: To get the bath bombs out of the molds, gently tap the top of the mold with a spoon, then twist the top and bottom in opposite directions to open.

For best results, allow your bath bomb to sit for an additional 24 hours once out of the mold before using it.

How to Use Bath Bombs

Once your bath bomb is completely dry and hardened, it is ready to use. Fill your bathtub with warm to hot water and place the bath bomb into the water. As the water soaks into the bomb, it will start to fizz.

Or you can hold the bath bomb underneath the running water and allow it to fizz in your hand.

If you don’t want to use the whole bath bomb in one bath, you can remove it from the water and set it on the side of the tub.

Next time you want to use it, just throw it back into the water.

How to Color Bath Bombs Naturally

Bath bombs can be left white, or there are several natural options for colors. The best colorant for bath bombs is mica powder.

Mica powder is a colored powder that can mix straight into the dry ingredients before mixing in the wet ingredients.

Natural food coloring or skin-safe dyes can also be used to color bath bombs and even my homemade shower bombs.

Natural food powders like beet powder, matcha, cocoa, or hibiscus powder can be used to naturally color your bath bombs.

For these tropical bath bombs, I choose bright summer colors like orange, yellow, and blue.

Best Bath Bomb Molds

Green, blue, and purple tropical bath bombs shaped as a seashell.

In the past, I have always stuck to round bath bombs. However, for these tropical fruit bombs, I found some fun-shaped molds to make them look more festive.

You can find a lot of different options online for bath bomb molds or even make your own with old Christmas ornaments or Easter eggs.

As long as you have something that has two halves that can be pressed together, you can make a bath bomb.

Eco Friendly Bath Bombs

Bath bomb making can be very eco-friendly. When you are finished making your bath bombs consider storing them in a reusable basket, heavy-duty BPA free plastic container, or just set them on the bathtub.

Save your bath bomb molds for the next time you want to make bath bombs to save money and to avoid any extra waste.

Avoid using glitter and unnatural colors and dyes to make your bath bombs eco-friendly. If using mica powder, be sure it doesn’t have any added glitter.

Mica powder itself can have a natural shimmer and is a great option for making bath bombs safe for the environment.
