The Helsi™ Ice Plunge is an ice bath that chills itself. Fill it once, plug it in, and it holds the water between 0 and 42 °C, kept clean by ozone, a filter and UV light. No ice to buy, no plumbing.
An ice bath (or cold plunge tub) with a chiller has a built-in cooling unit that holds the water at the temperature you set, and water care that keeps it clean. You never buy ice. The Helsi™ Ice Plunge cools down to 0 °C with a 1.5 hp compressor, warms up to 42 °C and cleans the water automatically every 4 hours with ozone, a 20-micron filter and UV light. It runs on a standard 10 A power point and needs no fixed water connection.
Ten years of cold plunging, and the Helsi™ Ice Plunge
Jason Gilbert has looked after professional surfers for 20 years. Here he shows the plunge he uses now: the step in, the depth, the ice on the surface.

Care
Water care that runs on its own
The ice bath does most of the cleaning itself. Your part is a quick look at the filter and the water values: pH 7.2 to 7.6. Shower briefly before, close the lid after, and skip chlorine.
Every 4 hoursAutomatic cleaning cycle with pump, ozone and UVautomatic
Every 2 weeksRinse the filter with clear water
MonthlySoak the filter in diluted hydrogen peroxide
Every 1 to 3 monthsReplace the filter and change the water
“What stood out to me with Helsi is how well thought through everything is. From customising the temperature to having actual ice on the surface within hours, it’s clear a lot of care has gone into the design. The plunge itself is deep, a true full-body experience, and it’s very easy to get in and out. The build quality is excellent, and it complements both my gym and sauna perfectly. It’s something I’d recommend to anyone looking to make cold therapy a consistent part of their routine.”
1 to 3 minutes is a common guideline. Neoprene socks and gloves help against cold feet and hands.

Warm up
Then close the lid.
Don’t get into cold water alone the first few times. If you have a heart or circulation condition, high blood pressure, or are pregnant, check cold exposure with a doctor first.

0 to 42 °C, adjustable. On low settings ice forms on the cooling coils in the insulated walls.
No. You fill it with a garden hose; the connectors fit 1", 3/4" and 1/2". A fixed water and drain connection is possible, by an installer.
A standard 10 A earthed power point protected by a 30 mA RCD (safety switch). It draws 1,400 W.
Power times running time times your electricity price. One hour at full load uses 1.4 kWh, about $0.49 at $0.35 per kWh. The chiller only runs when the water is warmer than set.
Every 1 to 3 months with normal use, sooner if the water turns cloudy, foams or smells. A quick shower before, a closed lid and the water values (pH 7.2 to 7.6) make it last longer.
Yes, with the insulated lid and the outdoor cover. Switched on, Active Flow keeps the water moving and limits the minimum temperature to 3 °C. In long, hard frost put it into hibernation: switch off, drain, store protected.
Only with a structural engineer’s approval. Filled, the Helsi™ Ice Plunge weighs 765 kg on about 1.5 m², over 500 kg per square metre. Most balconies are not built for that.
Below 70 dB.
The unit is 75 cm wide and fits standard doors. You open the crate (215 × 87 × 120 cm, 280 kg) where it is delivered; then the ice bath rolls on its own wheels.
Mostly the words mean the same. The difference is the build: a tub with ice, a tub with an external chiller, or an ice bath with a built-in chiller.
Another word for an ice bath: a tub of cold water you sit in up to your shoulders. The Helsi™ Ice Plunge is a cold plunge with a built-in chiller.
1 to 3 minutes is a common guideline. A calm, controlled response to the cold matters more than the duration.
