How to Take a Seaweed Bath and Why


Today’s blog topic is on How to Take a Seaweed Bath and Why. After all, who doesn’t need a relaxing and nourishing bath after the year we’ve had so far!
And so, on to the blog!

Seaweed has been decorating the Irish coast for centuries, so I’m sure you’re no stranger to the green salty tendrils that kiss your ankles at the beach.
Indeed, the Irish diet has included seaweed as part of its traditional coastal diet for decades. And for good reason too! Seaweed has a long history in ancient medicine, folklore and farming in Europe, particularly in Ireland.
If you want to learn more about seaweed itself, have a read over my blog post:

What’s the Scoop on: Seaweed

There I go into what seaweed actually is, what types there are and the culinary benefits of seaweed.
In contrast, today’s blog focuses on how to use seaweed externally.

Perhaps if you live on the West Coast of Ireland you’ll already be accustomed to seeing many people entangled in ribbons of seaweed along the coastline in the bathhouses.
For those of you who don’t live along the coast or have access to such delights, that’s where home seaweed baths come in. You can enjoy the therapeutic benefits of a seaweed bath at home in your own bathtub!

Why Take a Seaweed Bath?

Seaweed baths are linked to a variety of health benefits thanks to their minerals, vitamins, trace elements and polysaccharide content.
These baths are used for all kinds of ailments since they:

  • help lower body stress
  • aid in the relief of skin conditions such as psoriasis, eczema, acne etc.
  • help reduce muscle aches and pains
  • reduce joint stiffness (rheumatism and arthritis)
  • support circulation
  • detoxify the body
  • nourish and moisturise the skin
  • relieve inflammation
  • stimulate healing and repair in the body
  • promote sleep
  • support the endocrine system
  • benefit the lymphatic system
  • help against the signs of ageing
  • have natural anti-cellulite properties
  • improve suppleness and elasticity of the skin
  • tone and stimulate the skin

I must admit, as someone who tends to get a bit nervous going anywhere near the sea if there’s seaweed floating in it, I was a bit nervous the first time I decided to take the plunge and test out the benefits of a seaweed bath. Slippery green and brown tangles on my skin didn’t appeal to me, however, I was pleasantly surprised.  
The fact that it offered so many benefits, one major one being a stress reliever, was the final push I needed.
Seaweed is essentially concentrated seawater, therefore it’s packed with minerals such as magnesium, iodine and vitamin K to all aid in overall relaxation.

How Do You Take A Seaweed Bath?

If you’re not a fan of the idea of slimy fronds of seaweed floating around, then not to worry. You can keep the seaweed inside the netted bag that it comes in. As a bonus, you can actually use this net full of minerally goodness to scrub your skin gently like a loofa.

We stock two fantastic seaweed bath products for you to try out. We stock both Carraig Fhada Atlantic Seaweed Bath and Wild Irish Seaweed Bath. 

How to Use:

  1. Immerse the seaweed (which is in a netted bag) for about 20 minutes in a container of very hot water. This allows the seaweed to hydrate completely and release its natural oils.
  2. Then, fill your bathtub with water (at whatever temperature you require) and add the contents of the container to your bathwater.
  3. Gently squeeze the seaweed bag for maximum oil release, but do be careful. The centre of the seaweed may be quite hot still.
    Feel free to use the seaweed net as a loofa to gently exfoliate your skin and enhance circulation a bit.
    And don’t worry if you notice an amber colour coming out. It’s natural and comes from the iodine content. It won’t stain your skin or your bath.
  4. Now all you have to do is enjoy a good soak for 20 minutes or more to get the benefits thoroughly saturated into your skin.
  5. Once you’re finished bathing, don’t forget to keep your seaweed nett safe. You may re-use the seaweed within 48 hours for a second bath.

I wouldn’t recommend adding any additions to your seaweed bath. Using your normal bath products such as body washes, shower gels or bubble bath could make the natural oils in the seaweed less effective.

A little word of warning.

Yes. It is fairly smelly. Don’t expect a romantically fragrant bathroom experience. Be prepared for a more fishy seaweed smell. Or perhaps we could go as far as saying a smell that brings long walks on the beach and holiday smells to your bathroom.

Also, do keep an eye out for Sebastian – be aware that this is a natural product and you may encounter some small crustaceans, shells and stones.


After you’ve used your seaweed bath net a couple of times, it may be handy for you to know that it’s biodegradable and makes excellent garden compost and fertiliser.

If you don’t have a bath, it is possible to use these nets in a foot bath, though of course, you’ll probably want to do a few to get the most out of it.
