How to Choose a Bath Bomb Kit in the UK – Buying Guide

How exciting it is to be making your own personalised bath bomb at home! Our buying guide will show you how to choose the best kit for this craft according to the ingredients and supplies in the kit, so read on to find out more.

Choosing Either a Bath Bomb DIY Kit or Mould Set Depends on the Supplies You Have at Home

To successfully make bath bombs at home, the first step is to make sure you have all the crucial ingredients and tools. Carry on reading so you'll know if you prefer a DIY kit or a mould set!

DIY Kits Contain All the Necessities to Create Your Bath Bombs

DIY Kits Contain All the Necessities to Create Your Bath Bombs

If this is going to be your first time making bath bombs, you might want to consider purchasing a DIY kit as it contains all the necessary ingredients and tools. In this type of kit, you will definitely find bicarbonate of soda and citric acid for making the bath bombs, as well as at least one mould for you to shape them. 


You'll also benefit from the other ingredients included in this kit such as colourings, fragrance oils and even biodegradable glitter! However, with the limited ingredients provided, the bath bombs you'll be making will look more or less the same in terms of their design. 

Mould Sets Only Include Moulds and Other Useful Tools

Mould Sets Only Include Moulds and Other Useful Tools

If making bath bombs is your passion or even if you're starting a small business, you might want to invest in a mould set instead. They will usually come with at least six spherical moulds so you will be able to yield half a dozen in one go.


Since these sets don't contain any bath bomb-making ingredients, you'll have to order bicarb, citric acid, and maybe even other ingredients to get started. However, with you being the one to choose the colours and scents, you can create signature bath bombs that are unique to your style or brand! 


It's also very common for mould sets to include shrink-wrap bags and sometimes even gift bags, so these are a great pick if you're planning on gifting your creations to some lucky recipients.

What Other Ingredients Are Included in the Kit?

What Other Ingredients Are Included in the Kit?

As we've mentioned already, DIY kits contain the most crucial ingredients: bicarbonate of soda and citric acid. However, if you purchase a commercial DIY kit, you might only get these two ingredients and some extra decorations, whereas you'll have more ingredients provided when purchasing kits from small businesses.


DIY kits from small businesses usually contain more fun and skin-loving ingredients for you to add to the bath bombs, so just look for whichever you'd prefer. Other basic ingredients such as oil and corn starch add extra moisture to your bath and slow down the fizzing process so you can watch it dissolve gradually. 


And of course, depending on who you buy the kit from, you'll get a variety of colourings and fragrance oils in your kit to make colourful and aromatic bath bombs, so you can choose kits in your favourite colours or scents.

Other Useful Tools to Look for Include Gloves, Spray Bottles and Gift Bags

Other Useful Tools to Look for Include Gloves, Spray Bottles and Gift Bags

While you know moulds are definitely included in both DIY kits and mould sets, you might want to check out what other useful tools are included to help you craft these exciting products!


For example, if you're crafting your items to give as Christmas presents, look for fun or beautiful wrappings that will make your bath bomb gift extra special. Tools such as a spray bottle and gloves will keep your hands clean, and if they're included you won't have to go and source your own at an extra cost. 


Mould sets, on the other hand, tend to include more practical tools such as test tubes or measuring spoons for accuracy when adding the ingredients. Sometimes, you'll even have a mini sealer which will allow you to flawlessly seal the plastic wraps off the bath bomb.

Finally, Check How Many Bath Bombs the DIY Kit Yields

Finally, Check How Many Bath Bombs the DIY Kit Yields

With all the ingredients included in the DIY kit, you're probably keen to know how many bath bombs it will yield. The minimum yield is always clearly stated by the brand on the purchase website, so if you're looking to turn your kitchen into a bath bomb factory, you might want to make sure you get a kit that produces big quantities!

As a final point, while most bath bombs yielded are spherical, there are some available which create half-spheres or other shapes. Whichever you fancy, be sure to buy a DIY kit that will produce your ideal bath bombs

A Hassle-Free Factory You Can Use Again and Again

We think both kids and adults would love to have a go on this product as it has an adorable mixing station and moulding machine. First mix the powder and water in the station, then transfer it to the moulding machine to make a perfectly round bath bomb. Don't forget to hide the surprise characters too for an exciting reveal!


Even if you've used up all the ingredients included, you can always purchase more bicarbonate powder mixture to make more batches of bath bombs. This is a great money-saver for parents as it's cheaper than buying a new kit every time as well as being cheaper than buying individual bath bombs from the shops.

A Great Starter Mould Set for Your First Bath Bomb Business

If you're very serious about starting a small bath bomb business, this is the set you'll want as it includes all the packaging and corresponding tools you'll need. With up to 100 colourful wraps included, can happily seal up your bath bombs while your clients appreciate the simple yet eye-catching packaging with adorable stickers. 


When your business continues to grow, you might want to invest in the packaging materials individually as you would be able to distribute your products in a more cost-effective way.

Make Your Own Crystal-Filled Geode!

Next up, a simple DIY kit that will allow you to make crystal geodes to enjoy in your bath – just add water to the bicarbonate powder mixture and decorate with sprinkles and coloured crystals. This set proves making bath bombs can take no time to craft!


This product, however, is aimed mainly at children and it does produce semi-spherical bath bombs instead of whole spheres. Plus, while it fizzes in the water like other bath bombs, the colours aren't vibrant enough to drastically change the colour of the bathwater.

A Set Containing Metal Moulds and Coloured Dye Only

We like to call this set a 'minimalist' mould set as it only contains two crucial tools and ingredients to make your bath bombs: six metal moulds and twelve coloured dyes. This means you could yield four big bath bombs in one go while experimenting and creating a new shade of colour with the soap dyes.


This product can be considered as a step-up set for those who are ready to take bath bomb-making more seriously and want to invest in a good set of metal moulds and soap dyes that will last quite a while.

Get Creative With Bath Bombs in Various Exciting Shapes

The impression of bath bombs is that they're spherical but with this mould set, you'll be able to impress everyone with bath bombs in shell, clamshell, football and even doughnut shapes! With three measuring spoons included as well, you can accurately pour in the appropriate amount of liquid to make your bath bomb mixture. 


While other tools such as stickers and gift bags are included as well, there isn't a large amount of them. That's why we think this set is best suited for those who like to gift their craft to their lucky friends every once in a while

Extra Ingredients to Personalise Your Bath Bombs

By chance, if you decided to go after the mould set, you might want to take a look at these extra ingredients so you can make beautiful personalised bath bombs – without having to make several orders or trips to the shops!
