Rank #5 in Best Cold Plunge Tubs 2026: 10 Ranked, and Why the Numbers Don't Add Up
Replenished 370L Cold Water Therapy Tub with Dome Lid
Price and rating as shown on Amazon when we collected them. Both change.
The Replenished ice bath (model 5070002508038) is the tub at number five in this guide, and it is the cheapest entry in the set at £69.99. It is also the one with the largest stated capacity: 370 litres. Divide the price by that figure and the listing works out at roughly 19p per litre of stated capacity, the lowest of the fourteen tubs we compared.
Two numbers on the same page do not sit together. The listing shows 4.3 out of 5 from 142 ratings, but the star breakdown underneath it totals 100 — 72 five-star, 10 four-star, 7 three-star, 6 two-star and 5 one-star. There is a second gap of the same kind: the tub is listed at 3.5 kg, and 370 litres of water weighs roughly 370 kg once it is filled. Everything on this page comes from the Amazon listing as it appears, not from a tub we filled or tested ourselves.
