DIY Bath Bombs: How to Make Your Own at Home

DIY bath bombs have become increasingly popular in recent years as people look for ways to create their own spa-like experiences at home. Bath bombs are small, colorful balls that dissolve in water and release a variety of scents and oils that can help to relax the body and mind. Making your own bath bombs is a fun and easy way to customize your bath time experience and save money on expensive store-bought options.

Understanding Bath Bombs Before diving into the world of DIY bath bombs, it's important to understand how they work. Bath bombs typically contain a combination of baking soda, citric acid, and essential oils or fragrances. When the bath bomb comes into contact with water, it fizzes and dissolves, releasing the scents and oils into the water. Some bath bombs also contain additional ingredients like Epsom salts or dried flowers to enhance the experience.

Step-by-Step Guide to Making Bath Bombs


Before starting, gather all the necessary ingredients and tools. This includes baking soda, citric acid, cornstarch, Epsom salt, essential oils, food coloring, mixing bowls, measuring cups, and molds. It's important to have everything ready to go before starting the process to avoid any mistakes.

Mixing the Ingredients

In a mixing bowl, combine the dry ingredients: 1 cup baking soda, 1/2 cup citric acid, 1/2 cup cornstarch, and 1/2 cup Epsom salt. Mix well until all the ingredients are evenly distributed.

Next, add 2-3 drops of your desired essential oil and a few drops of food coloring. Mix again until the color is evenly distributed and the scent is well incorporated.


Once the mixture is ready, it's time to mold the bath bombs. Take a small amount of the mixture and pack it tightly into the mold. Repeat until all the mixture has been used. Let the bath bombs dry in the mold for at least 24 hours.

Drying and Storage

After the bath bombs have dried, carefully remove them from the molds. Store them in an airtight container to prevent them from losing their fizziness. Keep them in a cool, dry place away from sunlight.

Making bath bombs at home is a fun and easy DIY project that anyone can do. With this step-by-step guide, you can create your own luxurious bath bombs in no time.

Safety Precautions

When making DIY bath bombs, safety should always be a top priority. Here are some important precautions to keep in mind:

  • Protective Gear: Always wear gloves and a mask when handling ingredients, especially if you have sensitive skin or respiratory issues. It's also a good idea to wear an apron or old clothes that you don't mind getting messy.
  • Proper Ventilation: Make sure you're working in a well-ventilated area to avoid inhaling any fumes or dust. If possible, work near an open window or use a fan to circulate air.
  • Careful Mixing: When combining ingredients, be sure to mix them thoroughly and evenly. Avoid overmixing, as this can cause the mixture to dry out or harden too quickly.
  • Avoid Moisture: Keep your ingredients dry and avoid using wet utensils or molds. Moisture can cause the mixture to activate prematurely, ruining your bath bombs.
  • Storage: Store your finished bath bombs in a dry, cool place away from sunlight and moisture. Keep them out of reach of children and pets, as they can be mistaken for candy or toys.

By following these simple safety precautions, you can ensure a safe and enjoyable DIY bath bomb making experience.

Common Mistakes and How to Avoid Them

When making DIY bath bombs, there are several common mistakes that can ruin the final product. Here are some tips to avoid them:

1. Using Too Much Liquid

One of the most common mistakes when making bath bombs is using too much liquid. This can cause the mixture to become too wet and not hold its shape. To avoid this, it is important to add the liquid gradually and mix it in well before adding more. If the mixture becomes too wet, you can add more dry ingredients to balance it out.

2. Not Using Enough Binding Agents

Another common mistake is not using enough binding agents such as cornstarch or kaolin clay. These ingredients help to hold the bath bomb together and prevent it from crumbling. If you find that your bath bombs are falling apart, try adding more binding agents to the mixture.

3. Using Too Much Essential Oil

While essential oils can add a lovely scent to your bath bombs, using too much can be overpowering and even irritating to the skin. It is recommended to use no more than 1-2% of essential oil in your bath bomb mixture. Be sure to measure carefully and mix well to ensure the scent is evenly distributed.

4. Not Packing the Mixture Tightly Enough

When making bath bombs, it is important to pack the mixture tightly into the mold to ensure it holds its shape. If the mixture is too loose, the bath bomb may crumble or fall apart. Use a spoon or your fingers to press the mixture firmly into the mold, and tap the mold gently on a flat surface to release any air bubbles.

By avoiding these common mistakes, you can create beautiful and fragrant bath bombs that will make your bath time a luxurious experience.

Customizing Your Bath Bombs

Making your own bath bombs is a great way to personalize your self-care routine. By customizing your bath bombs, you can create unique scents and colors that fit your preferences. Here are some ideas for customizing your bath bombs:

Adding Colors

One of the best parts of making your own bath bombs is the ability to add colors. You can use food coloring or natural dyes to create a wide range of colors. To add color to your bath bombs, mix a few drops of colorant with the dry ingredients before adding the wet ingredients.

Using Essential Oils

Essential oils are a great way to add scent to your bath bombs. Not only do they smell great, but they also have therapeutic benefits. Lavender essential oil, for example, is known for its calming properties, while peppermint essential oil is invigorating. Be sure to use high-quality essential oils and follow the recommended usage rates.

Incorporating Extras

You can also add extras to your bath bombs to make them even more luxurious. Some popular options include dried flowers, such as lavender or rose petals, or Epsom salt for added relaxation. You can also add glitter or mica powder for a touch of sparkle.

By customizing your bath bombs, you can create a spa-like experience in the comfort of your own home. Experiment with different colors, scents, and extras to find the perfect combination for you.


DIY bath bombs are a fun and easy way to add some excitement to your bath time routine. By using simple ingredients and following a few basic steps, anyone can create their own unique bath bombs.

One of the benefits of making your own bath bombs is that you can customize them to your liking. You can choose your own scents, colors, and even add in some skin-nourishing ingredients. Plus, making your own bath bombs can be a fun activity to do with friends or family.
