The 6 Best Bath Bomb Molds

There is a big market right now for molds as the whole world gets more creative at home. We have a greater appreciation for homemade items and the process of making something special. We see this with something as straightforward as silicone molds for resin casting to molds for candles, soap, fondant, and more. You can also add bath bombs to this list. So, what are the best bath bomb molds and what should you look out for?

Why Should You Make Bath Bombs At Home In Molds?

Bath bombs are a wonderful luxury and it can be fun to browse them in store. However, they can also get expensive. If you love adding these to your own bath or gifting sets to friends and family, it might be more cost-effective to make your own. It is also a lot more rewarding to present a homemade bath bomb that was made with love and care – especially if you can guarantee that the ingredients are vegan or that there is a specific scent that they love.

Things To Consider When Choosing The Best Molds For Bath Bombs

1) The material used for the molds. As you may be aware from my other guides and general arts and crafts, molds come in all kinds of materials. Silicone molds are great for a lot of materials, but not so much with bath bombs. Aluminum is much better for a well-defined shape and for removing the bomb. Plastic can be a bit cheap and ineffective.

2) The number of pieces in the set. You will find a lot of companies stating the number of pieces in a set. This is important for bigger kits where there are pieces of tissues paper and bags as well. But, be aware that 12 pieces doesn’t mean 12 shapes. Instead, it means two pieces per shape as you need to fit two halves together.

3) The themes of the shapes included. A lot of sets will use traditional spheres as this is what most people expect from a bomb. They are also the easiest to make. But, you can also get some nice novelty items, such as hearts, shells, and donuts.

4) The additional tools for the bomb-making process. Some sets will include some tools to make it easier to create the products, such as scoops for the mixture or a heat sealer for shrink-wrapping the final bomb. But, these are rare.

5) The additional materials for gift making. These are more common as so many of the best bath bomb mold kits are for gift making. You can often find some gift bags in addition to the shrink wrap. They are mostly small mesh pouches but a nice touch. Some also offer tissue paper and stickers for more color.

With this in mind, I have selected a series of products that offer a range of options with varying approaches. Some are quite simplistic for beginners as a starting point. You can use these quality molds to play with mixtures and colors and perfect the techniques. Then there are some novelty items for a bit of fun. Finally, I have some more comprehensive sets where you get those additional tools and materials for a more complete process.

I think that this set might be one of the best for those with no previous experience in making bath bombs. The metal molds follow the standard spherical shape, which we all love to put in a bath. These should be easy to use with the quality aluminum shapes and clean shapes. There are three sizes in the pack, with six molds in total. There may not sound like a big difference between the 6cm and 4cm shapes, but it is noticeable and it means you can tailor gifts to different people. I also like that they come in a nice eco-friendly box. Reviews are mixed, but some users may be using incorrect recipes.

Pros:

1) Clean and high-quality aluminum molds

2) Three sizes in the same pack

Cons:

1) A beginner set before moving on to something more interesting

If you don’t want to use a standard mold for spherical bath bombs, you might appreciate this donut shape. There are actually two different sizes available – one is 8cms in diameter and the other 9.5. You should end up with a clean shape that mimics a ring donut and then play with “strawberry”, “chocolate” and “vanilla” colors for your mixes. You can then package the bomb up in a box for added effect. Some users recommend making a bomb in half of a mold because of the size. It depends on the recipient.

Pros:

1) The donut shape is great fun

2) There are two sizes to choose from

Cons:

1) Too big for some when using the whole mold

This next option offers a bit more variation without getting overwhelming with additional items. There are 6 shapes in total with the traditional sphere, a heart, a starfish, and some shells. The molds are aluminum with matching lids for that double-sided texture. The material is easy to use and clean out, which means you can also use them for other materials. There are some mixed comments about these molds, with some saying that the results aren’t perfect. Therefore, this might be better as a starter kit than as something for commercial items or gifts.

Pros:

1) A nice range of sea-themed shapes as well as the standard mold

2) Aluminum shapes that are easy to use and cleanout

Cons:

1) Mixed results so better for beginner projects

Next, I want to move onto a more complete set. I think these are a great idea for fuller projects if you are just getting started. You should find most of what you need for making gifts here. This is a 154 piece set when you add everything up. There are three molds for spherical bombs, a soccer ball, shell, scallop, and donut. You also get tools to help you out and some great materials for packaging bombs for gifting. This includes shrink wrap bags, tissue paper, stickers to hold the paper in place, gift bags, and a plastic container. The downside to this cheaper set is the amount of plastic used. The tub isn’t the most attractive.

Pros:

1) Some fun shapes to try out

2) Tissues and stickers to decorate your gifts

Cons:

1) A lot of plastic

Next, is a set that is similar to the set of sea-themed molds above. Some of the shapes are very similar and I wouldn’t be surprised if they came from the same supplier. There are five shapes with the spheres, heart, shell, scallop, and starfish. This time, you get some additional materials in the set for packaging the finished goods and giving them out to friends and family. You get a heat sealer for the shrink wrap bags – which isn’t in the set above – and drawstring mesh bags. The downside here is that you don’t get the tissue paper or stickers for added decoration.

Pros:

1) Plenty of fun themed molds

2) A free heat sealer to make use of the shrink wrap plastic

Cons:

Finally, we have what might be my favorite option for anyone looking for a gift for keen crafters or for something to do with the kids. This set is beautifully packaged with everything you are meant to need to make bombs. I appreciate that some won’t like this because there isn’t that variation of molds. But, you do get a quality metal sphere for casting and all the additives to make your first bombs. This includes four scents, colors, and petals. It is a vegan-friendly set that can inspire younger users to work with one of the sets above in the future.

Pros:

1) A full starter kit for younger users

2) Some great colors and scents to play with

Cons:

1) Just one mold in the box


Getting Started With Bath Bomb Molds

If you are completely new to this craft, it is best to go for something easy and then expand from there. The STMT kit is a great gift for teens to get an understanding of the process before moving onto a different set of molds with your own ingredients. There are some high-quality spheres out there for traditional gifts, which are made more appealing when you get the bags and tissue paper. But, you can also have a lot of fun with the donuts and shells. The important thing is to see what shapes inspire you to get creative and how the sets can make it easier to create the perfect gift.
