Bath salt with the Thermomix® is not a recipe but a three-step system. We mix 500 g of Dead Sea salt dry with food colouring and a few drops of essential oil, 25 seconds at speed 4, then fill it into airtight containers. No water, no oil in the salt. Per full bath you use 2 to 3 tablespoons (about 100 to 150 g) at around 37 °C water temperature. In 20 minutes you have three finished jars: unicorn, orange and rose blossom.

We have made all three versions hundreds of times. The unicorn bath salt in colourful layers, the orange bath salt with real zest and the rose blossom bath salt with dried petals. Each follows the same principle and is ready in under ten minutes of active time. The reason we make it in the Thermomix® rather than stirring by hand is explained in the next section.

Colour.
Add the Dead Sea salt to the mixing bowl. Zest the orange and add the zest. Add the orange essential oil and orange food colouring (adjust quantity to reach the desired colour intensity) and mix for 25 sec / speed 4. If the colour is not evenly distributed, mix for a few more seconds.

Filling.
Fill the orange bath salt into containers and seal airtight.
Why we mix the salt dry at speed 4
The Thermomix® distributes colour and fragrance evenly through the salt without any stirring on your part. 25 seconds at speed 4 is enough for 500 g. No longer than that, because the salt would become too fine and lose the coarse grain that crackles so nicely in the bath water. If the result still looks streaky after 25 seconds, add a few more seconds in 5-second increments. Two short bursts are better than one long one.
There is a second reason for mixing dry. The moment salt comes into contact with water, it partly dissolves and forms lumps that cannot be smoothed out again. That is why we wipe the mixing bowl between batches with a dry kitchen towel only and never rinse it with water. This is exactly where the Thermomix® makes the difference: by hand you will never distribute three colours as streak-free, and the zest will never be as finely worked through the salt as it is at speed 4.
Dead Sea salt, Epsom or sea salt: what belongs in the jar
We use 500 g of Dead Sea salt as the base, and that is a deliberate choice. Dead Sea salt is rich in magnesium, potassium and calcium and has been used for years on dry and itchy skin. It leaves the skin feeling softer after bathing than ordinary table salt does. The coarse grain also means the colour adheres well and the salt flows nicely when pouring.
Epsom salt (magnesium sulphate) is the alternative if you want to absorb magnesium through the skin. It is finer and takes colour less readily, so we keep the colouring more subtle with it. Plain sea salt from the supermarket works too, but has fewer minerals. What should not go in the jar is table salt with anti-caking agents: it clumps faster and feels scratchy on the skin. If you like, mix 400 g Dead Sea salt with 100 g bicarbonate of soda to soften the water.
Unicorn bath salt: layering rather than mixing

For the unicorn bath salt we colour the 500 g in three separate batches, so roughly 165 g per colour: yellow with gold glitter, pink with a glitter colour of your choice, blue with silver glitter. Each third goes into the mixing bowl with a few drops of food colouring and some glitter for 25 sec / speed 4, then into its own small bowl. Wipe the mixing bowl dry between each batch.
The filling only works if you layer the salt in alternating colours. Yellow, pink, blue, yellow again. That is how you get the colourful stripes that define the unicorn bath salt. If you pour everything in at once, the colours blend together as they settle and turn a muddy brown-grey. A tall, narrow jar shows the layers off better than a wide one.
Orange bath salt: zest delivers the fragrance

For the orange bath salt, 500 g of salt, the zest of 1 unwaxed orange, 5 to 10 drops of orange essential oil and orange food colouring all go into the mixing bowl together, then 25 sec / speed 4. The orange peel contains essential oils that are released when it is broken up. The Thermomix® grinds the zest and distributes it finely through the salt. The added orange oil strengthens the fragrance, because the zest alone weakens after drying in the salt.
Using an unwaxed orange is important. Treated peel carries wax that cannot be distributed evenly and leaves unsightly patches in the salt. Organic oranges are the safer choice here. Zest the orange thinly, keeping as little of the white pith as possible, otherwise the flavour turns bitter.
Rose blossom bath salt: dried petals keep the salt dry

The rose blossom bath salt needs 500 g of salt, 2 tbsp of dried rose petals, 5 to 10 drops of rose essential oil and pink food colouring, all together for 25 sec / speed 4. The rose petals must be dried, otherwise they bring moisture into the salt, and that is the quickest way to lumps. Dried petals keep the salt free-flowing. The rose oil provides the fragrance, the petals provide the visual effect.
The pink colour completes the effect. Without colour the salt looks like grey road grit with brown crumbs. With pink food colouring it becomes a proper rose bath salt. If you prefer a stronger scent, combine the rose oil with a few drops of vanilla, which takes the sharp perfumed edge off the rose.
The three most common pitfalls with homemade bath salt
The salt clumps after a few days
Bath salt draws moisture from the air and from any damp ingredient. The most common mistake: using fresh rather than dried petals, a wet mixing bowl or a jar that does not seal properly. Our solution: wipe the mixing bowl dry only, use exclusively dried petals and fill the finished salt into a jar with a swing-top lid. That way it stays free-flowing for months.
The unicorn colours turn brown-grey
This happens when you add all three colours to the mixing bowl at once or just tip everything in together when filling. As the salt settles, the pigments blend into a muddy tone. Our solution: mix each colour separately, put it into its own small bowl and layer the colours alternately in the jar. Only then do the stripes stay cleanly separated.
The salt becomes too fine and dusty
If you mix the salt for too long or at too high a speed, you grind it to a powder. The coarse grain that crackles in the water is lost, and it creates dust when you open the jar. Our solution: stay at speed 4 and start with 25 seconds. Only mix again if the colour is still streaky, and then only in 5-second increments.
More scent and colour variations to try
The basic system stays the same throughout. We simply swap the colour and the scent. A few combinations that work well for us:
- Lavender for sleep: 500 g salt, 1 tbsp dried lavender, 8 drops lavender oil, purple colouring. The classic evening bath.
- Eucalyptus for colds: 500 g salt, 8 to 10 drops eucalyptus oil, no colouring. The steam rising from the warm water clears the nose.
- Lemon and mint to wake up: zest of 1 organic lemon, 5 drops peppermint oil, yellow colouring. The fresh version for a morning bath.
- Adding a conditioning oil: If you like, add 1 tbsp of almond or jojoba oil directly to the bath rather than into the salt jar. The salt stays dry and your skin still gets the conditioning benefit.
How to build a wellness gift set with the bath salt
Bath salt works well as part of a homemade wellness gift set. We combine it with homemade foot balm and bath bombs made with the Thermomix®. For unicorn fans, a small bottle of unicorn liqueur makes a fun addition. Anyone making the full set will find more ideas in our Thermomix® Cosmetics collection.
How to store the bath salt so it stays free-flowing for months
Bath salt draws moisture from the air. In an open jar it clumps within a few days. Jars with swing-top lids keep the salt free-flowing for months. It retains its colour and fragrance for roughly three to six months. Jam jars with screw-top lids also work, as long as the lid seals properly. With honey jars, check that the rubber seal in the lid is still intact.
Store the jars away from the bathroom, in a dry and dark spot such as a bedroom cupboard. The humidity right next to the shower is the main reason bath salt clumps faster than expected.
