Beauty on a Budget: DIY bath bombs and bath salts

DIY Bath Bombs

We all love to relax in the bath after a busy day and adding a bath bomb to our tub can make the experience even more luxurious. By learning how to make DIY bath bombs, you can skip the more expensive ready-made versions and save money.

But that is not all. By making your own DIY bath bombs, you will also know exactly what has gone into them and can avoid any ingredients that might irritate your skin.

What are bath bombs?

Invented in the late 1980s, bath bombs are essentially tightly-packed balls of ingredients which will ‘fizz’ in your bath when they get wet. Also, they usually include ingredients such as essential oils and are a way to get these varied oils (as well as scents and colours) into your bathwater.

And because they fizz when you drop them into warm water, they make the whole bathing experience feel that little bit more extravagant and exciting.

DIY bath bombs: for budget and choice

If you go to the high street to buy a bath bomb, you could be looking at anywhere from £3 to £6 per bath bomb, making them a rather expensive treat.

By making your own, it can cost you much less than the high street price per bomb and you will also be able to choose the ingredients you would like to soak in.

Even better, many of the ingredients needed to make a bath bomb will already be in your store cupboard. And even if they are not, you can buy enough ingredients for many bath bombs, fairly cheaply. By buying in bulk, you could also cut the cost per bomb.

Bath bombs come in all sorts of colours, fragrances and oils, each creating a slightly different bathing experience. You could also pack your bath bombs with things such as glitter or rose petals, so you can choose to make something that suits your taste and mood.

You will need to buy bath bomb moulds to pack your bath bombs into but these inexpensive and reusable moulds are readily available on online shops, such as Amazon. Alternatively, you can use muffin or cupcake moulds, but remember to oil them beforehand so that the bath bombs come out easily!

DIY bath bomb for relaxation

diy bath salts

Many of us like to take a bath at the end of the day to help us unwind. Research has even suggested that baths could help you to get a better night’s sleep because of the rapid temperature drop you will experience after you get out of a hot bath.

Ideally, you should take your soak about two hours before you go to bed.

Lavender is an ideal scent to put into a relaxation DIY bath bomb, as it is known to have a relaxing and calming effect.

‘Relax me’ bomb


  • 150g Bicarbonate of Soda
  • 50g Citric Acid
  • 5ml of Lavender Oil
  • A few drops of natural purple food colouring
  • A little Olive Oil for greasing
  • You will also need disposable rubber gloves and a plastic water spray bottle


Wipe your moulds with olive oil to prevent your bombs from sticking.

Put your gloves on.

Put your bicarbonate of soda and citric acid into a mixing bowl (preferably glass or metal). Mix them together.

Add a few drops of your colouring until you get a nice lavender shade. You will need to mix the colouring in quickly to avoid your bomb mixture starting to fizz.

Add your lavender oil and mix thoroughly.

Spray your mixture with a little water at a time – make sure you are mixing continuously otherwise your mixture could start to fizz! Only add enough water so that your mixture begins to hold together when you gently squeeze it in your hand – make sure that it is not too wet.

Then, quickly squeeze your mixture into your moulds (following any instructions that came with the moulds).

Leave your bath bombs to set for around half an hour. Then, when the bath bombs are hard enough, lift them out of their moulds and leave them to dry.

The number of bath bombs you’ll get from this recipe depends on the size of your moulds.

Keep your bath bombs in an air-tight container, until you are ready to use them.

Rainbow DIY bath bombs

Rainbow bath bombs are a great alternative to the solid colour varieties and can help to make your bath a much more colourful experience.

Create a rainbow effect by following the ‘Relax me’ recipe above, using a different food colouring for each batch. Then layer the colours on top of each other inside your moulds.

For example, you could make a green batch with peppermint oil, a purple batch with lavender oil and a yellow batch with lemon oil. Then layer them together in your moulds to form a stunning-looking bath bomb!

DIY bath salts: a great alternativeBeauty on a Budget: DIY bath bombs and bath salts

If you are not fussed about creating fizzy bombs for your bath time, DIY bath salts are a great alternative. Some research has shown that using bath salts could have a large range of health benefits including better circulation, headache relief and could even benefit acne or other skin problems.

By mixing Epsom salts with baking soda and the essential oil or oils of your choice, you could make a jar full of wonderfully relaxing bath salts to store next to your bath. Just scoop a spoonful of the salts out and drop them into a steaming bath, as and when you want to unwind.


DIY bath bombs and bath salts are an affordable beauty treat to enhance your bath time and help you to wind down at the end of a long day.

Bath bombs and salts also make great gifts for your friends and family. Once you have mastered the more basic recipes, you can start to add your own twists.
