Liquid castile soap has so many uses all around the home, as part of your green beauty routine, or as part of your eco-friendly cleaning routine. In fact, I wouldn’t be without it! Whether I’m making all-purpose cleaning sprays or tackling dirty floors, it’s one of the first products I reach for.

If you are looking to incorporate the wonder that is liquid castile soap into your life then here’s where to shop for castile soap.

Here are my favourite places to pick up this all-natural household staple – from branded Dr Bronner’s liquid castile soap to the cheaper unbranded versions.

Use the quick links to navigate to a specific section or keep scrolling for the full post:

Big Green Smile

Big Green Smile stocks one of the widest ranges of Dr Bronner’s liquid castile soap I’ve found in the UK. With 11 different scents – from tea tree or citrus, right through to eucalyptus, rose, and cherry blossom – in varying bottle sizes, it’s often my first stop when shopping for soap.

And what’s to love about Big Green Smile is that it even sells 60 ml sample bottles, in a variety of scents, for just £2.49. This is great if you’re new to using castile soap, and want to try it out before committing to buying a larger bottle.

Sephora UK

Sephora UK is another stockist that carries a range of Dr Bronner’s liquid castile soap. Here you’ll find 237 ml bottles, in a small range of scents, all priced at £9.69.

Whilst the selection is a lot smaller than at Big Green Smile, it is handy if you are stocking up on budget-friendly eco beauty products and need to add on a bottle of castile soap for your green cleaning needs.

Ethical Superstore

Ethical Superstore also stocks a small range of Dr Bronner’s liquid castile soap. Here you’ll find both the citrus and peppermint scented soaps in handy 473 ml bottles and lavender liquid castile soap in the massive 3.8-litre bottle. Prices for these range from £13.29 to £77.99.

As it carries such a small range, I personally find Ethical Superstore a good option when I’m buying other ethical or eco-friendly goods, and happen to need a bottle of liquid castile soap too.


If you are looking to specifically buy unbranded liquid castile soap then Etsy is a great place to go for picking up larger quantities of soap at lower prices. Here you can find a litre of soap for around £12.88 (at the time of writing).

To compare a 3.8-litre bottle Dr Bronner’s soap costs around £69.99. At £12.99 for a litre of unbranded soap, to buy 3.8 litres works out at £38.94. It’s a huge cost difference. I don’t buy liquid castile soap in this quantity though. I haven’t found any need for my general household needs – so unfortunately I’m unable to compare the quality of the castile soap. If it’s something I do try though, I’ll be sure to update here with my experiences.

You might be wondering why Etsy. You might associate Etsy as the place to go when looking to buy goods handcrafted by makers and artisans. However, it’s a little-known fact that Etsy is also a great place to shop for supplies – particularly supplies for making body care products. Hence why Etsy has a huge range of unbranded liquid castile soap available, at great prices.

I hope you’ve been able to find what you are looking for! As always, when I find more top places to buy both branded and unbranded versions I’ll be sure to update this guide!
