Cold water immersion has moved from elite-athlete recovery rooms into serious home wellness in the last few years, and the evidence base behind it is now substantial. Used regularly — and especially in combination with a sauna — a cold plunge supports recovery, sleep, immune function, mood, and metabolic health. We stock one ice bath because it is, in our judgement, the right one for New Zealand homes.
The Tomas Ice Bath
The Tomas Ice Bath is a stainless steel hot-and-cold plunge unit with precise temperature control from 2°C to 39°C, WiFi connectivity, ozone sanitation, and smart filtration. It works as a cold plunge in summer, a contrast therapy unit year-round, and a hot soak when you want one. Unlike a converted chest freezer, the Tomas is purpose-built for this use — the hygiene, temperature accuracy, and longevity are dialled in from the start. From $5,999.
The science, briefly
Repeated cold exposure has been linked in published research to reduced inflammation, improved insulin sensitivity, increased brown fat activation, and meaningful improvements in mood and stress resilience. The dose matters — most protocols recommend two to three minutes of immersion at 10–15°C, two or three times a week — and consistency matters more than intensity. The Tomas removes the friction of preparing cold water from scratch, which is the single biggest reason people stop using ice baths.
Why pair it with a sauna
The biggest gains often come from pairing cold immersion with regular sauna use — what’s called contrast therapy. Twenty minutes of heat followed by two minutes of cold, repeated two or three times, produces a powerful effect on the cardiovascular and lymphatic systems. We offer several contrast therapy bundles that pair a Pure Sweat sauna with the Tomas at a combined discount — these are the most popular setup our customers buy.

Who cold therapy is right for
Cold therapy genuinely benefits anyone training hard, anyone dealing with chronic inflammation or stiffness, anyone working on stress resilience, and sauna users who want the full Finnish-style hot-then-cold experience.
It’s not the right tool for everyone. If you have a serious cardiovascular condition, talk to your doctor before starting. We’re happy to discuss whether it suits your situation — just give us a call.
