Single-digit cold
Temperature
A chosen set point replaces seasonal guesswork. The water is genuinely cold before the session begins.
Controlled cold. Standing shower. No plunge tub.
An ice shower gives you single-digit cold without climbing into a tub.
An ice shower actively refrigerates its own water, holds the temperature you choose and delivers it across both shoulders. You get serious, repeatable cold in the bathroom routine you already know.
Actively chilledNot limited by mains water
Temperature controlledRepeat the same cold daily
Built for standingNo plunge tub or immersion
The difference is refrigeration
Your tap delivers the weather. An ice shower delivers a set point.
A normal cold shower is an excellent way to begin, but the water can only get as cold as your home supply. On a warm day, “fully cold” may still be mild.
An ice shower removes that ceiling. It chills water before it reaches the body, then keeps fresh cold moving across the skin for the entire session.
Feel what that changes
What single-digit water feels like
The cold arrives everywhere at once.
At 5°C, there is no searching for the cold spot. Wide moving water demands a response immediately, then rewards a controlled breath.
- First hitYour attention locks onto the water.
- Next breathA slow exhale puts you back in control.
- AfterwardsYou step out alert, clear and completely awake.
Four parts. One repeatable ritual.
Chill the water. Hold the temperature. Deliver it over the body.
A reservoir, cooling unit, pump and overhead delivery head work together. The result is fresh, controlled cold from the first second to the last.
- 01
Fill a dedicated reservoir
The system starts with its own water supply, so the temperature is no longer limited by whatever reaches your household tap.
- 02
Refrigeration removes the heat
Active cooling pulls the water down to a chosen temperature without bags of ice, frozen bottles or a separate freezer.
- 03
Set the cold you want
Begin at a temperature you can control, then lower it as your breathing, confidence and routine improve.
- 04
Fresh cold covers both shoulders
The shower continuously delivers chilled water across the upper body for a fast, standing cold-exposure session.
The three numbers that decide the experience
Temperature makes it cold. Flow and coverage make it powerful.
A low number on a display is not enough. The water has to stay cold while it moves, and enough of it has to reach the body at once.
Cold that keeps moving
Flow
Continuous flow prevents a thin layer of water from warming against the skin and losing its intensity.
Both shoulders at once
Coverage
A wide overhead pattern puts more of the upper body under cold water, making every short session count.
Colder water creates the intensity. Strong flow preserves it. Wide coverage makes every second count.
Cold shower, ice shower or plunge
Keep the ritual fast without compromising the cold.
A cold shower is the easiest start. A plunge offers immersion. An ice shower combines controlled temperature with the speed and familiarity of standing under water.
| Compare | Cold shower | Ice shower | Cold plunge |
|---|---|---|---|
| Temperature | Whatever reaches the tap | Actively chilled to a set point | Controlled reservoir |
| Daily start | Turn the tap | Press start | Open the tub and step in |
| Body exposure | Standard shower stream | Wide moving coverage | Near-full immersion |
| Space required | Existing shower | Existing shower or bath area | Dedicated tub and floor space |
| Repeatability | Changes with the season | Same chosen temperature every day | Repeatable when maintained |
| Best fit | Starting the cold habit | Fast, intense daily exposure | Longer immersion sessions |
The ice-shower advantage: keep the speed of a shower, then make the water colder, controllable and repeatable in every season.

Use serious cold seriously
Start higher. Breathe normally. Lower the temperature gradually.
Cold water can trigger rapid breathing and a sharp cardiovascular response. Stop if you feel faint, dizzy or unwell. Speak to a clinician before deliberate cold exposure if you have a heart or circulation condition or a history of fainting.
What is an ice shower?
An ice shower is a purpose-built system that actively chills its own water and delivers it over the body while you stand. The temperature comes from refrigeration rather than the household mains supply or the weather.
Does ice fall from an ice shower?
No. The name describes the temperature, not falling ice. Refrigeration chills liquid water into a controlled, single-digit range before the shower delivers it over the body.
How is an ice shower different from a cold shower?
A normal cold shower can only use the coldest water reaching your home, so its intensity changes by city, building and season. An ice shower actively chills water to a temperature you choose and can repeat.
Is an ice shower the same as a cold plunge?
Both create deliberate cold exposure, but the format is different. A plunge immerses most of the body in a tub. An ice shower keeps chilled water moving over the body while you stand, making shorter bathroom sessions possible.
Does OLSEK need new plumbing or drilling?
No. OLSEK is a self-contained system designed to sit inside an existing shower or bath area. Its adjustable rail mounts without drilling, and the Cooling Core works from its own 15-litre reservoir.
How cold does OLSEK get?
OLSEK can be set anywhere from 15°C down to 1°C. That range lets beginners start higher and gives experienced cold users access to near-freezing shower water.
How many showers come from one fill?
The 15-litre reservoir supports up to four short ice-shower sessions per fill, depending on the flow setting and session length.
