Out of all the DIY beauty products, bath bombs are probably the most creative ones, because there are so many ways to make and decorate them.

The easiest and the most effective way to make an interesting-looking bath bomb is to use a quirky bath bomb mold. 

Bath bombs don't have to be round. They can be any shape you want. For example, egg shape bath bomb for Easter, lip-shaped molds for Valentine's day, candy cane shape for Christmas and so on. You get the idea.

I searched the web and picked the coolest unique bath bomb molds I could find. If you are an experienced bath bomb maker, you've probably experimented with different molds for bath bombs already. But I guarantee that you will find some amazing bath bomb molds on this list.

So without further ado, here is the list of 20 unique bath bomb molds for foolproof awesome bath bombs:

1. Unique rose flower bath bomb mold

Is it bad to start with my favorite?

This is the most gorgeous flower bath bomb mold I’ve ever seen. Its shape reminds me of LUSH bath bombs.

Bath bombs made with this mold will look gorgeous without much effort, just like the plain purple bath bombs in the picture. They look feminine and sweet. And it is easy to make them more fun or more luxurious. Just add glitter, flower petals or multiple colors to achieve different looks.

This is a good quality and easy-to-use mold. You can read reviews and buy it here.

2. Coolest ever waffle-shaped bath bomb mold

Waffle-shaped bath bombs are simply amazing. First of all, they look beautiful, especially when made in multiple colors. Second, they are quite big, so you can get lots of foam and color. You can purchase waffle bath bomb mold from this seller.

4. Cupcake bath bomb mold

If you love cupcake bath bombs, but don’t want to mess around with the frosting, this unique bath bomb mold might be the perfect solution.

This mold is made from two parts just like the classic round bath bomb mold. Due to it being plastic, it is very easy to use, as bath bomb mix does not stick to it and bath bombs can be easily removed. Cupcake bath bombs can look great on their own but if you want to take it to the next level, consider dipping the top in melted cocoa butter mixed with mica powder and then adding sprinkles.

7. Strawberry shortcake mold

I must say that this bath bomb mold looks quite boring on its own. But hey, no one said you should use it on its own. The dent in the bath bomb that this mold creates is there to be filled up with all the fun stuff: bath salts, dry herbs, flower petals and, of course, the frosting. 

It is called strawberry shortcake but as the image above suggests the decoration options go way beyond desserts. You can buy, read reviews and see examples of bath bombs made from this mold here.

8. Chill pill mold

Many of us use bath bombs to relax after a long day. This chill pill bath bomb mold represents that perfectly. Pop this pill in the bathtub and enjoy a relaxing bath.

Mooncake press comes with 5 different stamps, so you can get a variety of bath bombs. You can see some photos of bath bombs made by customers here. Before buying, consider the size you want. For bath bombs, I would recommend the 100g size press. 50g ones are quite small.

10. Doughnut bath bomb mold

Doughnut shaped bath bombs are very popular at the moment. Mostly because of the fun drizzle and sprinkles that go so well with it. I’ve seen some really colorful and fun doughnut bath bombs like in the image above and also some realistically looking chocolate doughnuts.

If you never made a drizzle, don’t worry, it is very easy. Just mix melted cocoa butter and baking soda to get the consistency you like, add color and drizzle with the spoon over your doughnut bath bomb. Add some cute sprinkles on top and you’re done. The cocoa butter will cool down and become solid just like you see in the image above.

Out of all doughnut shaped bath bomb molds that I've seen this one is my favorite one. First of all, it is a high-quality mold. It is made from thick durable plastic, that does not bend. Second, the 3-part mold makes it easy to press and remove bath bombs. Third, this is the only doughnut bath bomb that I've seen that allows making a full (double-sided) doughnut fizzie instead of just half of it (with a flat bottom).
