7 Simple Ingredients for the Perfect DIY Bath Bomb

There are few things in life as soothing as a good warm bath after a long, stressful day. But you can take it one step further and make it even more relaxing with bath bombs. Not only do they make for a fun DIY project, but they also deliver a variety of fun fizzling sensations that help to relax your muscles and help relieve stress. In addition to that, they also contain ingredients that are good for your skin and hair, making them a win-win in more ways than one.

However, not all bath bombs are created equal, and some don’t contain the necessary ingredients to make them worth using. If you’re interested in creating your own bath bombs but you don’t know where to start, we’ve got you covered. If you’d rather have bath bombs delivered straight to your door, we can help with that too!

1) Baking Soda

Baking soda is an essential ingredient in bath bombs because it creates an effervescent effect that helps deliver additional sensory elements. Moreover, it is good for your skin and hair—which we know you want in your bath bombs. It also has deodorizing properties, which can help neutralize smells and add a subtle scent to your bathing experience. However, too much baking soda can be harsh on your skin, so you’ll want to use just enough to create bubbles without stripping your skin of natural oils.

2) Citric Acid

While it is a good idea to use a little bit of baking soda in your bath bombs, using too much can create a salty aftertaste. This is where citric acid comes into play because it balances out some of that saltiness while helping to provide a subtle lemony scent. To be clear, citric acid doesn’t create bubbles like baking soda does; however, it plays an important role in creating that perfect citrusy smell and taste. It also serves as an important moisturizer for your skin and hair. Further, if you’re going to work with citric acid, make sure you’re wearing protective clothing and eyewear at all times since it can cause irritation if left on your skin or eyes for extended periods of time.

3) Epsom Salt

We’ve already talked about some of the benefits of baking soda and citric acid, but that is just a portion of what Epsom salt can do. For example, it contains magnesium and sulfate, which help improve your skin and hair. It also helps to detoxify your body by flushing out toxins and improving circulation, all things you want in a bath bomb. While we recommend using Epsom salt in your bath bombs, don’t use too much, or you’ll end up with a salty smell rather than one that is citrusy (like most people prefer).

4) Corn Starch

The corn starch found in bath bombs is there to bind all of your ingredients together and serve as a thickening agent. However, too much corn starch can leave your skin feeling tight and dry; you’ll want to use just enough to create a smooth texture. In addition to binding everything together, it will also help keep your finished bath bomb from crumbling when you pour it into water.

5) Essential Oils

The true secret ingredient of bath bombs is essential oils. These oils provide everything from subtle scents to aromatherapy benefits. If you’re making your own bath bombs, you can use any variety of essential oil; however, you should take care not to use too much of it because it can be quite strong. Many people recommend using about 15 drops per batch of 10-12 bath bombs.

6) Coloring Pigments

All those fun, bright colors you see in bath bombs? They’re not natural—they’re added with coloring pigments. But don’t worry; they are completely safe to use in your homemade creations. The cool thing about these little guys is that there are a ton of them out there, and they come in a variety of shades and finishes; some even make it look like your bath bomb has glitter on it when it fizzles away in the water. So, if you want a multicolored bathing experience, just add multiple types of pigment to each batch.

7) Bath Bomb Molds

Perhaps the most important ingredient of bath bombs is something that often gets overlooked. If you’re going to make bath bombs, you’ll need molds of some sort. In fact, it can be pretty hard to make a bath bomb without a mold of some kind because it takes quite a bit of time and effort to get those little guys rolled into perfect balls. Some people even use extra bowls or muffin tins as molds, so they don’t have to spend money on a special set.


If you follow these steps and make sure you measure everything correctly, we’re confident that you’ll end up with a batch of bath bombs that everyone will love. While there is a lot of room for experimentation and testing, just remember to have fun with it! Happy crafting!
