Splitting CBD bath bombs into two and using them on several occasions is a good way to save on cost because CBD products are expensive, but the split parts will not be as effective as whole CBD bath bombs. You can gently cut the bath bomb into two and store each part in a ziplock bag or an airtight container.

If you want to split and store CBD bath bombs to have several pieces for more than one occasion, you can cut them carefully into two or more parts (depending on the size) and place the split parts in an airtight container or a ziplock bag. Besides, you need to keep the halves in a cool, dry environment to ensure they don't interact with hair and start fizzing. Remember, fizzing can happen in the air, only that water fastens the process, especially when it is warm and adds energy to the molecules. Here is all you need to know about splitting and storing CBD bath bombs. 

Understanding CBD and CBD Bath Bombs

According to Massi et al. (2016) and Bauer et al. (2020), CBD is the non-psychoactive chemical compound in hemp and other species of cannabis plants. There are about 140 such compounds in cannabis, with CBD being one. Still, it stands out among the rest for being non-psychoactive and being able to express effects without causing the 'high' effect.

CBD bath bombs are like regular bath bombs, only that they have an additional ingredient; CBD. According to Watt & Karl (2017), CBD is therapeutic, and people tap on its products for such benefits. More research is needed to prove the therapeutic effects of CBD in CBD products, but anecdotal evidence shows that the cannabinoid has so much to offer. Besides, they boast essential oils like lavender oils, which, according to Djilani & Dicko (2012), are therapeutic and medicinal.

How to Use a CBD Bath Bomb

A bath bomb is one of the easiest CBD products to use and requires no special instructions. Many people like it because, unlike CBD oils and tinctures that are bitter, a bath bomb does not have to go through your mouth, so you will not feel its taste. Using a CBD bath bomb is as easy as following the steps below;

  1. Fill the bathtub with warm water. While cold water may also work, warm water is better since it promotes the fizzing action and fast dissolution of the CBD bath bomb.
  2. Dip the CBD bath bomb into the water
  • Allow 6- 8 minutes to pass and let the CBD bomb dissolve completely
  1. With the CBD bath bomb fully dissolved, climb into the bathtub
  2. Enjoy the color patterns, fragrance, and other ingredients in the CBD bath bombs by soaking in the water for 20- 30 minutes

Can I Split CBD Bath Bombs?

You can split CBD bath bombs into two or four pieces, depending on the size of the bath bomb, and use them for more than one occasion. Because of many reasons, including the murky legal status of CBD, the cost of growing hemp and processing CBD, and the novelty of the cannabinoid, CBD products, including CBD bath bombs, are expensive. Consequently, people look for ways to save on costs, and many think about cutting the bath bombs. It is possible to split CBD bath bombs; you can split one bath bomb into two or four parts, allowing you to enjoy the pieces on more than one occasion. Learn more about ready for a cbd bath bomb

Are CBD Bath Bombs Effective When Split?

While one can split CBD bath bombs into two or more parts, depending on the size, many wonder if the bath bombs remain effective afterward. What marks the effectiveness of CBD bath bombs? The fizzing action; as baking soda and citric acid in the bath bombs react, fizzing happens. You can split CBD bath bombs are somehow effective since the fizzing ingredients can still react when the bath bomb is halved or cut into four.

Is that all there is? Split CBD bath bombs have their fair share of flaws. For instance, while they fizz, the action is fast when the bath bomb is halved. Cutting the bath bomb means a bigger surface area is exposed, making the reaction happen quickly. Therefore, you will not enjoy the fizzing action for long if you choose to cut the CBD bath bomb twice or four times to use them in more than one bathing session.

Splitting a CBD Bath Bomb: How to Do It

Do you want to split your CBD bath bomb into two or more pieces and use them on more than one occasion? The size of the bath bomb matters, informing how far you can go with the splitting process. For instance, the small-sized CBD bath bombs cannot be split; they are small and only deserve to be used in one session. Meanwhile, you can cut the medium or large CBD bath bombs into two or four parts. Here is how to go about it.

  1. Wipe dry a clean surface
  2. Spread a piece of paper or cloth on the working surface
  • Place the CBD bath bomb on it
  1. Hold it gently, and using your knife, cut it slowly but surely until it is divided into the needed parts
  2. Pick one for your bath and store the others. Learn more about how do cbd bath bombs work

How to Store CBD Bath Bombs: Whole and Split

CBD bath bombs need proper storage, without which they will react and fizz before you can use them. If this happens, they will not fizz in warm water since the acid-base reaction of baking soda and citric acid can happen in the air. Keep the cut or whole CBD bath bombs in a ziplock bag or an airtight container to prevent air entry. Besides, keep the storage conditions cool and dry to prevent humidity and air that could trigger premature fizzing. Moreover, ensure you use CBD bath bombs fast, probably within the first month of purchase.


Splitting CBD bath bombs into two or more pieces helps you save on costs. Still, it is not effective since the fizzing action may happen faster than intended. Splitting the bath bomb is easy; you only need a knife, a working surface, and calmness to prevent the bath bomb from crumbling. Once done, keep the pieces in an airtight container, put them in a cool, dry place, and use them fast.
