Rank #6 in Best Cold Plunge Tubs 2026: 10 Ranked, and Why the Numbers Don't Add Up
simpa 330L Ice Bath Tub with Lid and All-Weather Cover
Price and rating as shown on Amazon when we collected them. Both change.
The simpa Large Black & White 330L Ice Bath Tub is sixth in this guide. It is a cold plunge pod sold with a lid and an all-weather cover for £44.99, rated 4.4 out of 5 and sitting 126th in Amazon's Soaking Baths category. Against its own stated capacity, that works out at roughly 13.6p per litre.
What the simpa listing does not give is dimensions — there is no length, width or height anywhere on the page for the 330-litre figure to be checked against. What it does give is two review counts that disagree. The header states 34 ratings; the star breakdown further down the same page lists 65 at five stars, 22 at four, 7 at three and 6 at one, which is 100 ratings in total and averages to exactly the 4.4 shown. Everything on this page comes from the Amazon listing and the customer reviews published on it, not from any testing of our own.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Excellent for the price.Nice and sturdy plus it's big enough for a 6ft 22 stone fatty 😂”
Verified purchase“I have to say I'm really impressed with this for the money! For less money than a takeaway you can have yourself this product. It is very good quality with all accessories. I am 6ft 4" and 22st and I fit in this so it's a decent size albeit I struggle to get my head under, but sitting there up to my shoulders is good enough for me. The base is soft and foamy so very comfortable to sit for prolonged periods of time.”
