“Been using this every morning since January. The insulated lid genuinely keeps it cold overnight with a Chill Core 300 running — water's still at 4°C by the time I get in.”
Marcus Ellery
on Kaldera Plunge 320
“Fits my husband at 6'2" with room to spare, and the frame hasn't budged after three months of daily use. Folds down small enough to store behind the shed.”
Priya Nathwani
on Kaldera Plunge 320
“Solid tub, well made. Only reason it's not five stars is the drain valve is a bit fiddly to seat properly the first few times.”
Dan Okafor
on Kaldera Plunge 320
“Upgraded from a cheaper 200L tub and the difference in build quality is obvious immediately — the steel frame doesn't flex at all when full.”
Lucy Fairweather
on Kaldera Plunge 320
“Quiet, holds 4°C rock steady, and the titanium coil gives me peace of mind since I run treatment drops through the water regularly.”
Sam Whitcombe
on Chill Core 300
“Does exactly what it says. Takes a while to pull down from a warm summer fill, but once it's there it stays there.”
Anna Kowalczyk
on Chill Core 300
“Paired with the Plunge 320 and it's been completely maintenance-free for two months. Filtration keeps the water genuinely clear.”
Ben Okonkwo
on Chill Core 300
“Buying the bundle took all the guesswork out of sizing a chiller to the tub. Arrived together, set up in an afternoon, no compatibility issues.”
Rachel Tanaka-Smith
on Kaldera Starter Bundle
“Cheaper than buying the tub and chiller separately and I didn't have to think about which chiller size to pick. Exactly what a first-timer needs.”
Ollie Petursson
on Kaldera Starter Bundle
“Great value bundle. Instructions could be clearer on hose routing but customer support answered quickly when I asked.”
Grace Adebayo
on Kaldera Starter Bundle
“The six heat zones make a real difference — warmer at the feet, cooler at the chest, so I can actually stay in for the full 30 minutes.”
Tom Halvorsen
on Ember Sauna Blanket
“Gets properly hot, folds away neatly in the bag. Wish the controller cable was a touch longer but otherwise no complaints.”
Isabel Marchetti
on Ember Sauna Blanket
“Run this before my plunge every evening now. The PVC-free liner doesn't get that clammy feeling other blankets I've tried have had.”

Getting started
Set up your tub anywhere with a hose or a few buckets. Flat-pack frame, up in minutes.
Dial in 3–15°C on a Chill Core and let it hold temperature — no ice runs, no guesswork.
Two to five minutes, most days. The insulated lid keeps it cold and ready for tomorrow.
The Science
Cold water immersion after hard training can ease the muscle soreness and perceived fatigue that build up over the following days, helping you come back to your next session feeling fresher.
Bleakley et al. 2012, Cochrane Database of Systematic Reviews
A cold plunge triggers a sharp rise in circulating noradrenaline and a jump in alertness. Many people describe the after-effect as a clean, sustained lift in mood and focus.
Šrámek et al. 2000, European Journal of Applied Physiology
Regular cold exposure is associated with a shift toward parasympathetic (“rest and digest”) activity and lower self-reported stress, which for many supports calmer evenings and better sleep.
Buijze et al. 2016, PLOS ONE
Cold water immersion is not a medical treatment. Consult a professional if you have cardiovascular conditions.
