I have always loved seaweed products. I used a powdered version for the bath {Seavite? I think so} that really required a strong drive to use, as it made a complete and utter mess of the bath after it was done. I mean, like, total ring-around-the-tub mess, and talk about a buzzkill, having to clean it up almost immediately after having sent all your tension down the drain.[Or else you have an argument with your live-in-fella-at-the-time because you let the mess go for a day or two, also a buzzkill.]

I wasn’t sure about this when I got the box. I mean, it’s a box. How’s seaweed supposed to fit in a box? I knew the Voya line very well, and have even had their seaweed baths, based in Strandhill, Co Sligo, on my to-do list almost since I moved to Ireland. I knew that the entire product line was organic, and that the seaweed itself is harvested by hand. I didn’t know that you could get it, freeze-dried into a roughly rectangular bundle.

Well, it is possible. The hunk of seaweed has been helpfully inserted into a mesh bag; there is, in addition, a wee bag of dead sea salt. <I wasn’t sure whether to captilise that or not, but Voya haven’t. Is ‘dead sea salt’ a thing that is separate now from the Dead Sea? Anyway: as instructed, I ran the bath full of hot, hot water and dropped the brick of weed in. I left the room to let it sit — I had to, because almost immediately the pure, salty scent of the seaweed began to waft around the bath. As I didn’t want to lose a layer or two of skin, which I would have done had I immersed myself, I went and did some email.

When I could bear it no longer, I went back and ran the water cold, sprinkled in some salt, and got in. Now, I love a good bath, and I go the full whack, with candles and a glass of wine, or when the circumstances demand, a short glass of Laphroaig, and appropriate musical accompaniment. Even then, I tend to get bored long before the water begins to cool. Not this time: I kept topping up the bath with as much hot water as it could handle without overflowing. I squeezed the now-football shaped net of weed to release even more of the gel that had infused the water. I was in there for almost 45 minutes.

If you take good care of it — I put mine in a large mixing bowl and covered the top with cling film — you can get another bath out of the ball. It’s not as transcendent as the first, but it is still pretty boss.

The re-hydrated bag of seaweed was pretty impressive, and also pretty: it bore no resemblance to the stuff that washes up on a beachy strand, and looked as if each… frond?… had been groomed to reveal its jagged beauty. I felt as relaxed as if I had visited the Strandhill baths themselves. This is a sublime treat for body and mind. Bonus: a cursory swipe of the bath the next morning was as hard as I had to work to clean up. In my book, there is no higher praise.
