Bath Bomb Molds – What to Look For
Whether you’re an eager crafter, looking to expand your soap-making business, or hoping to treat loved ones with delightful homemade gifts, bath bombs are a lot of fun. But just like soap molds, you need the right bath bomb mold.
Not knowing what to look for in a bath bomb mold can make the shopping experience overwhelming. The plethora of brands doesn’t make things any easier. With such a challenge before you, consider the following factors to help you zero in on the best bath bomb mold.
Material
Metal, plastic, and silicone are the most popular materials for bath bomb molds. Each has its pros and cons.
If you are after durability, then a metallic mold is your best bet. Aluminum and stainless steel make robust metal bath bomb molds.
The one downside with aluminum is that it tends to dent when dropped, banged, or tapped hard, flawing the bath bomb’s appearance. You then either replace the mold or accept the indentation as part of your design. You might also struggle a bit to release the bath bombs depending on the quality of the finish.
Stainless steel molds are the best bath bomb molds you can get your hands on. The material is the strongest and offers a smooth and sleek surface for the bath bombs to slide right off. They will last you a lifetime too. They are on the high end side, but if you look at it from an investment point of view, it is totally worth it.
Silicone molds are a favorite for pliability. The flexibility of the material makes the unmolding of bath bombs less tricky than metal and plastic molds. On the flip side, they may bulge and distort the actual shape with heavy compaction. Though reusable, silicone isn’t as durable as metal and may tear after repeated use.
Plastic bath bomb molds are ubiquitous, and fairly durable depending on the plastic grade, although they crack over time. They tend to be on the cheaper side.
Shape and Design
Are you going for the classic round bath bomb? You’ll have no trouble finding traditional dome shaped bath bomb molds.
Nonetheless, there’s a sea of shapes and designs to explore if you’d like to add a creative touch to your fizzles and make spa time more fun and exciting. There’s everything from stars to sea creatures, cupcakes to florals, to mention but a few.
You might also look into themed bath bomb molds, for instance, snowflakes designs for winter holidays.
Size & Capacity
You probably already have an idea of what size bath bombs you’d like to make, whether small, medium, big or jumbo. The mold you choose must correspond with the size you have in mind so pay attention to the indicated measurements.
Besides the cavity size, you also have to decide whether you want single or multi-cavity molds. The latter is ideal for making several bath bombs at a go, saving you time. Single mold sets may come with several individual pieces for a bath bomb making party or just a few for personal use.
Without further ado, let’s move to the most exciting segment of this bath bomb guide: the top 5 bath bomb molds.

2. Kyerivs Metal Bath Bomb Mold Set
Want to try out different shapes for your bath bombs? Kyerivs aluminum bath bomb molds would be the perfect mold choice.
The set comes in an assortment of cute ocean-themed molds including, starfish, scallop, shell, and heart shapes. There’s also the classic sphere in three different sizes: 1.77, 2.16, and 2.55 inches in diameter.
Made from a decent quality aluminum, the bath bomb molds are lightweight and easy to use and clean. The interiors are smooth and non-sticky, so your bath bombs pop out flawlessly.
They can last through several uses if handled gently, otherwise tap too hard and they’ll definitely deform.
The manufacturer even threw in several gift bags and drier bags which is a thoughtful gesture. It’s perfect if you’re starting a side business or planning to treat a group of people at once. However, the included heat sealer is below par, but if you’re buying it just for the molds, the set is still worth it.
3. Super Z Outlet Acrylic Bath Bomb Mold
These molds from Super Z are nothing like the other flimsy plastic bath bomb molds you’ve come across before. Super Z’s molds are a heavy duty crystal clear acrylic shell.
A pack contains a dozen round shells, and there are four sizes to choose from. You can go with the 60mm, 80mm, 100mm, and 120mm diameter molds for the jumbo bath bomb.
What makes these molds particularly stand out, unlike the previous three choices, is that the two hemispheres can be clipped closed and snapped open with relative ease. Now, there is nothing stopping you from leaving your bath bombs inside overnight or for a couple of hours.
They are lightweight, easy to pour in, and offer effortless after clean up. You might get a second or third round of use out of them if handled carefully.

We must mention that the capacity of the mold makes your bath fizzies much bigger than a regular bath bomb. Depending on how lightly or tightly you pack it, you can expect anything between a 7oz-10oz bath bomb from the approximately 3.3-inch high and 3.3-inch wide cupcake mold.
These bath bomb molds are simply fantastic and aesthetically pleasing. Your bath bombs will turn out so cute, you’ll want to munch them.
