Why Make Hand Soap At Home?
- By making your own hand soap at home, you are in control of what you put into your hand soap. There’s no need to use products with synthetic fragrances or unpronounceable chemicals.
- It is also more economical. With one bottle of castile soap you can make many many bottles of hand soap instead of buying an entirely new bottle every time you run out.
- Finally, you it is more versatile. You can use castile soap for washing dishes, cleaning countertops, and washing your hands.
Making your own castile soap hand soap is quick and easy. I’m almost embarrassed to call this post a “recipe”. But I didn’t know how simple it was before someone told me. So I hope you find this helpful too.
This is a recipe for foaming hand soap, but in the FAQ section I tell you how to adjust the recipe to make a liquid version of the soap, in case that is what you prefer.

Ingredients
Castile Soap – I like Dr Bronners. For hand soap recipes, I like orange, mint, or lavender.
Distilled Water – if you don’t have a water filter (like me), simply boil tap water and let it cool
Glass Foaming Soap Bottle – you can buy these online. But you can also simply reuse one you already have. Just rinse it out once the soap is gone and it’s ready for your castile soap hand soap mixture. A plastic bottle would work as well, but if you’re planning to use essential oils in your hand soap, it’s best to use glass.
Instructions
Fill a foaming hand soap bottle ¾ full of distilled water.
Fill the rest of the bottle with castille soap (about 2 tablespoons).
Give the bottle a shake. You may need to shake the bottle periodically when using it.
That’s it!
Ways To Use Homemade Castile Hand Soap
For washing your hands (duh!) – This soap works well for in the bathroom or at the kitchen sink.

For cleaning countertops – The soap is great as an all purpose cleaner for countertops in the kitchen and bathroom.
Castile Soap Variation Ideas
If you want, you can always mix up the soap scents that you use. Here are some ideas!
Spring – Try using orange castile soap.
Summer – Rose castile soap would be a great summer scent option.
Fall – Lavender castile soap would make a calming and cozy fall scent.
Winter – Peppermint castile soap would be a delicious smelling scent for winter.
FAQ
Here’s what I paid for make our latest batch: castile soap – £19 for 946ml, two foaming soap bottles: £10.99. This is a total cost: £29.99.
946ml = roughly 63 tablespoons, so this means that I should be able to make 31 batches of this hand soap. This means that after the first batch, each batch will cost about .63£ or about $1.
You may be able to find hand soap for this price in the supermarket, but are unlikely to find dish soap that is comparable!
And the added benefit of making your own is that you can control what goes into it. And you can avoid coming in contact with unwanted chemicals.
Castile soap is not 100% antibacterial. It works differently – it doesn’t kill bacteria, but rather lifts dirt, including bacteria off of surfaces.
You can consider adding a few drops of tea tree oil to your soap bottle, which can help to kill bacteria.
Yes. For a liquid version use about 1 cup of water and ¼ cup castile soap. The mixture will be more runny than the foaming mixture.
