Caldera's cold plunge: one person, water as low as 5 °C, held there by a heat pump and kept clean with UV-C. Find the spot, fill it, plug it in.
What Caldera's wellness team says regular cold exposure does. The hot tub is for the evening; this is for the morning, or for after training.
Cold exposure stimulates the release of norepinephrine and dopamine, which lift mood, motivation and mental sharpness.
Getting past the first seconds, again and again, trains the nervous system to handle stress calmly and lowers baseline anxiety over time.
A cold plunge wakes the body up. Depending on your health and tolerance, you step out refreshed and ready for the day.
Lowering tissue temperature helps muscles recover faster after effort, which is why athletes and active people use it.
Talk to your doctor before starting a cold plunge routine, especially with heart or circulation conditions or sensitivity to cold. This is general information from the manufacturer, not medical advice.
A variable-speed compressor brings the water down to as low as 5 °C and keeps it there, without ice and at a low running cost.
Closed-cell polyurethane foam, a sealed HDPE base and a custom-fit WeatherPro cover with a hinge seal keep the cold in.
A UV-C sanitising system and the EnergyPro circulation pump keep 425 litres clean between changes. A floor drain empties it.
The topside LCD sets temperature and lighting. There is nothing else to learn.
A multi-colour LED lights the water for an early start or a plunge after dark.
The same acrylic shell and maintenance-free cabinet as a Caldera spa, with five years of warranty on the shell.
Caldera's guidance for a first month. You set the temperature on the panel and the Emerge holds it.
Begin between 7 and 15.5 °C for one to two minutes. Extend the time and lower the temperature as your tolerance builds.
Aim for about eleven minutes a week in total. Consistency matters more than how cold or how long.
The first seconds are the hard part. Slow, rhythmic breathing helps you stay calm and stay in a little longer.
The shell comes in Arctic White. Choose the cabinet in Ash or Mocha and the insulated cover in Gray or Storm.
Much less than a hot tub. We check these four things with you before delivery.
It takes the floor space of a single bed: 224 × 107 cm, 74 cm high. Any firm, level surface.
About 280 kg/m², well below a hot tub. We still check the load on terraces and roof terraces.
It runs on a single-phase 230 V supply and draws 13 A. We confirm with you whether an existing socket will do.
Light enough to carry in by hand in most homes, with no crane. Our own crew delivers it and sets it up.
