When it comes to crafting the perfect bath bomb, picking the ideal mold is essential. From silicone molds and plastic forms to metal, to everyday objects like ice cube trays or muffin tins, there are plenty of options on offer for forming your bombs. Weighing up what each type has its pros and cons can help you make an educated choice when selecting a shape for your beauty product needs.

This article explores all that goes into deciding which kind of mold fits best with the bath bombs one desires to create. Taking features such as price point into consideration before making a commitment helps ensure satisfactory outcomes in producing desirable bathing treats!

Silicone Molds

Silicone molds are a great option for anyone who wants to make bath bombs that look professional. These molds offer the advantage of being durable, flexible and easy to use, so removing the final product is no issue! These may cost more than other types and require careful packing in order for your mixture not to crumble or crack. If you’re looking for high quality results without compromising on time investment then silicone could be exactly what you need.

Metal Molds

Metal molds are very sturdy. They create clearer and more precise shapes that may be difficult to create with other materials. They can be vigorously tapped to demold. But care must be taken as they can rust if not kept dry.

Plastic Molds

Using plastic molds for creating bath bombs is a more wallet-friendly option, especially ideal if you’re on a budget. While they are not as pliable as silicone ones, taking the finished product out of them isn’t difficult either. There’s one drawback – their durability and resistance to high temperatures may be inferior compared to silicone molds. All things considered though, for anyone looking for an affordable alternative when making bath bombs at home: plastic mold seems like the right choice.

Household Items

If you are looking for a way to make bath bombs without investing in dedicated molds, don’t worry. There are still plenty of options. Using everyday items like muffin tins, measuring cups and ice cube trays can create unique bomb shapes while keeping costs low. Although not as professional-looking or uniform as those from mold tools, these DIY versions will be just as fun and functional.

But this brings us into wondering: just how many possibilities do we actually have when deciding on the scents? Well basically an infinite amount could be reached here since they really depend solely from individual decisions alone.

In the following paragraphs are tips for making your personal batch bomb mix along with ratio levels together, plus mixing methods will be revealed so stay tuned.

Ingredient Ratios

Making sure the correct ratios for dry and wet ingredients are used is essential to make bath bombs that meet desired results. It’s recommended to use one part citric acid and two parts baking soda in the dry mix, as well as 1 to 0.5 ratio of oil-to-water in your liquid solution. Following these instructions can guarantee a satisfactory reaction from your fizzy treats. Excess liquids should be avoided since too much may lead to crumbling or underwhelming fizziness.

Scent Combinations

When creating bath bombs, there are no limits to what scent combinations you can try. Essential oils come in a wide variety of fragrances and choices that give plenty of options for customizing your own recipes. Examples include the fusions of lavender/peppermint, lemon/rosemary or grapefruit with bergamot mix. Get creative while mixing scents together. Just make sure to remember to dilute essential oils using carrier oil before adding only a few drops at once – so as not to cause any skin irritations or allergies.

From mixing wet and dry substances together to filling up the chosen mold form before leaving them out for drying, each step is indispensable to guaranteeing successful homemade bath bomb results.

The succeeding sections will provide comprehensive instructions on how exactly each stage of crafting should be done to obtain the ideal fizzy-smelling beauties. Creating well designed fragrant bath bombs shouldn’t seem too hard anymore.

A DIY Bath Bomb Recipe


  • 2 cups Baking Soda (Bicarbonate of Soda)
  • 1 cup Corn Starch
  • 1 cup Citric Acid
  • 1 cup Epsom Salts
  • 4 tsp Sweet Almond Oil 
  • 4 tsp Fragrance or Essential Oil (Your Choice)
  • 2 tsp Distilled Water
  • A few drops of Liquid Soap Dye (or food coloring)


  1. Add the dry ingredients in a bowl, (baking soda, corn starch, Epsom salts). Leave out the citric acid for the time being.
  2. In a separate bowl, add in the wet to include any food color or soap dye.
  3. Add the wet ingredients to the dry ingredients slowly a little at a time. Mix the ingredients well using your hands.
  4. Work the ingredients, until you get a texture of wet sand. The mixture should stick together.
  5. Now you add in the citric acid. Use gloves to continue to mix the ingredients as the citric acid can be an irritant at this point,
  6. Pack both halves of the mold with the mixed ingredients.
  7. Once packed, press the two halves together tightly so that the mixture bonds to each side. After a few moments, you can remove one half of the mold.
  8. Set the exposed half into a muffin tin to dry.
  9. Allow the bath bombs to dry for at least 24 hours, but 48 hours is better.

Mixing Dry and Wet Ingredients

Creating bath bombs begins by blending the wet and dry components together. Start with the above bath bomb recipe, then put all of your dry ingredients - baking soda, citric acid plus any optional extras, into one large mixing bowl. In another small bowl mix your wet elements such as essential oils, carrier oils along with colorants that are in liquid form. Gradually pour the moist substances into the mixture of dried items while stirring constantly to avoid premature activation from citric acid content . Keep incorporating until you get consistency similar to damp sand. Remember it is better to add less liquid at first since more can always be added if needed later on for desired texture/consistency regarding this specific DIY bath bomb project or other recipes following this same base process for making homemade bombs.

Filling the Molds

Once you have prepared the bath bomb mixture to an optimal texture, it is time to fill in your mold. If needed, oil or cooking spray can be utilized as a light coating for your molds (mold release) so that removing the finished product will not prove difficult later on.

When filling up each side of the two-part mold with spoonfuls or packing them firmly together with hands, make sure there’s some extra overfill so when they are joined no excess remains and a seamless bond forms between both sides.

Drying and Unmolding

Once you’ve finished filling up the molds, it’s essential to let your bath bombs dry. Allow them at least a day before taking them out of their containers. To safely remove the bath bomb from its mold, carefully tap on it so that no damage or breaking occurs while unmolding. After extraction from the mold, keep these items drying for one more day in order to make sure they are totally ready either for immediate use or storage purposes.

By sticking with this routine you guarantee an ideal bathing experience every single time as all shapes and fizziness will remain intact.

Troubleshooting Common Bath Bomb Issues

No matter how hard you try, there could still be issues in making bath bombs like crumbles and a lack of fizz. Fear not though. These can certainly be fixed through some troubleshooting tricks.

In the following parts, we will discuss ways to deal with usual obstacles when creating perfect bath bombs each time.

Crumbling Bath Bombs

If your bath bombs are crumbling, it is likely that the recipe was too dry or not packed enough in the mould. You can rectify this by adding some additional liquid and packing them more tightly into shape. Even after doing so, if you still find crumbled pieces then possibly adjust proportions of baking soda to citric acid as required for a stable outcome. Try various combinations and methods of tight pressing until desired results are achieved.

Lack of Fizz

If your bath bombs aren’t producing the amount of fizz you’re after, it’s likely down to either an incorrect ratio between baking soda and citric acid or too much oil being used in your recipe. To increase this effect, try raising the quantity of citric acid and/or reducing any oils present within its ingredients list. Doing so should lead to higher levels of bubbling which provides a better overall experience when taking a soak in these homemade bath bomb concoctions.
