Question 1

What's included with my Rhone ice bath?

Accepted Answer

Your Rhone arrives with the fully insulated tub, an insulated lid, two built-in chiller ports (3/4" BSPT), and matching caps to seal the ports. A chiller, hoses, and filters come separately, or together in one of our Rhone and Chiller bundles.

Question 2

What's included with the Rhone and Chiller Lite bundle?

Accepted Answer

The Rhone and Chiller Lite bundle includes the insulated Rhone ice tub and lid, the Theralpine Chiller Lite (cools to 3 °C, app controlled), two hoses, and the setup kit with adapters, valves, and seals. You can add 20-micron filtration with the optional Filter and Housing Kit.

Question 3

What's included with the Rhone and Chiller Pro bundle?

Accepted Answer

The Rhone and Chiller Pro bundle includes the insulated Rhone ice tub and lid, the Theralpine Chiller Pro (0 °C to 42 °C, ozone and 20-micron filtration), two hoses, the setup kit with adapters, valves, and seals, and four replacement filters. Everything to plunge, cool, and keep the water clean from day one.

Question 4

What makes the Rhone ice bath different from conventional ice tubs?

Accepted Answer

Above all, the insulation. Conventional ice tubs lose their cold quickly; the Rhone ice bath holds it up to 16x longer*: at 25 °C ambient the water warms by only about 0.06 to 0.07 °C per hour, versus up to 1.1 °C for a basic tub. Add a step-free, anti-slip entry, a comfortable seating position, and robust construction.

*Based on internal testing. Your results may vary with usage and ambient temperature.

Question 5

How long does the Rhone ice bath stay cold without a chiller?

Accepted Answer

Thanks to the strong insulation and the insulated lid, at 25 °C ambient the water warms by only about 0.06 to 0.07 °C per hour, roughly 1.5 °C a day.* So cold tap water or an ice fill stays pleasantly cold for a long time, not just a few hours like a conventional ice tub. Exactly how long depends on ambient temperature and lid use. For permanently precise temperatures, add a chiller.

*Based on internal testing. Your results may vary with usage and ambient temperature.

Question 6

What are the dimensions and weight of Rhone (empty/full)?

Accepted Answer

117 x 78 x 80cm (L x W x H), with lid. 117 x 78 x 75cm (L x W x H), without lid. Weight: 37kg empty, ~267 kg when filled with water at a typical fill level of 230L.

Question 7

Where can I install Rhone, indoors and outdoors?

Accepted Answer

Rhone is designed for both indoor and outdoor use. It's built with durable, UV-resistant materials to withstand sun, rain, and seasonal changes. We recommend placing it in a shaded or covered area when possible. This helps reduce dirt accumulation, supports consistent insulation performance, and avoids large temperature swings. While the lid is UV-resistant, extended sun exposure may temporarily cause slight flexing due to high heat. This naturally returns to normal as the material cools.

Question 8

What hose or chiller connections are supported?

Accepted Answer

Rhone features two female 3/4" (19mm) BSPT (tapered/Rc) ports, compliant with ISO 7-1 standards. We recommend using exclusively male 3/4" (19mm) BSPT (tapered/R) fittings for best compatibility. Please note: While we design and test our products for optimal performance and durability, we do not test third-party chillers, pumps, or accessories. As such, we cannot guarantee safety or results when using non-Theralpine components. Always install and secure all fittings carefully to avoid leaks or damage.

Question 9

How do I empty and drain my ice bath?

Accepted Answer

Rhone has a drain valve at the bottom, and the floor is angled slightly, so on level ground the water runs out on its own once you open the valve. No bucketing or pumping. Indoors, where the water needs to reach a drain, you can also use your chiller as a pump to move it there.

Question 10

What is the Rhone ice bath made of?

Accepted Answer

The Rhone ice bath is made from premium-grade roto-molded polyethylene, a particularly tough, impact-resistant plastic produced in the EU. At its core, a proprietary insulation foam is what keeps the cold in for so long. It's UV-resistant and weatherproof, so it withstands sun, rain, and frost, and it's built for daily use over years. Defects in materials and workmanship are covered by a 2-year warranty.

Question 11

How much water does the Rhone ice bath hold?

Accepted Answer

At a typical fill level, the Rhone ice bath holds around 230 liters, enough to submerge comfortably. Its maximum capacity is about 355 liters. Filled to 230 liters it weighs roughly 267 kg, so plan for a spot on firm, level ground. A standard garden hose is all you need to fill it.

Question 12

How does Rhone's insulation work in winter? Can the water in the tub freeze?

Accepted Answer

Rhone's insulation works both ways. It keeps the water cold in summer and resists freezing in winter. If temperatures remain below freezing for several days, a thin layer of ice may form at the surface, and it breaks up easily by hand. You can also add some warm water occasionally to maintain your desired temperature.

Question 13

Can I keep Rhone outside in freezing winter weather?

Accepted Answer

Yes. The tub itself is not at risk in freezing weather and comes through winter without trouble, even below zero. It's made from durable, UV-resistant, weatherproof material built for year-round outdoor use. Only your chiller needs its own precautions in frost.

Question 14

When will I start noticing benefits?

Accepted Answer

Often on day one. Most people feel a rush of alertness, a clear-headed calm, and a noticeable lift in mood right after their first plunge, holding for hours. With a regular routine, energy, focus, and sleep tend to improve within the first days, while deeper recovery and greater resilience to stress build over a few weeks.

Question 15

Is cold plunging actually healthy?

Accepted Answer

Yes. Regular cold exposure is linked to faster recovery, better mood and focus, a metabolism boost, and greater stress resilience. It is not a cure-all, but the benefits are real and documented.

Question 16

Is an ice bath safe, and who should avoid it?

Accepted Answer

For most healthy adults, yes, done gradually and sensibly. Cold immersion is a strong stimulus, so check with your doctor first if you have a heart condition, high or low blood pressure, a circulatory, respiratory, or neurological condition, or you are pregnant. Never plunge after alcohol, and always start gently.

Question 17

Does cold plunging help with weight loss?

Accepted Answer

It can support it, but it is no shortcut. Cold activates brown fat, which burns energy to produce heat, and briefly raises your metabolic rate. Over time that adds up alongside good diet and training, but on its own an ice bath will not melt fat. Treat it as a metabolic nudge, not a diet.

Question 18

Should I cold plunge before or after a workout?

Accepted Answer

After is the better choice; it eases soreness and speeds recovery. One nuance: if your primary goal is building muscle, avoid plunging within about an hour of heavy strength training, since cold can blunt the growth signal. After endurance sessions, or on rest days, plunge freely.

Question 19

What breathing technique should I use in an ice bath?

Accepted Answer

Keep it simple: a slow inhale through the nose, a longer exhale through the mouth, and stay still. This calms the cold-shock response. Important: do not do Wim Hof style hyperventilation right before or during the plunge, since combined with water it raises blackout risk. Save breathwork for before, on dry land.

Question 20

Is cold plunging safe during pregnancy or menstruation?

Accepted Answer

During your period, cold plunging is generally fine; listen to your body and skip it if it does not feel right. During pregnancy, the cold-stress response and blood-pressure changes mean you should check with your doctor first. When in doubt, ask a medical professional who knows your history.

Question 21

What does my first cold plunge actually feel like?

Accepted Answer

Intense for the first 10 to 30 seconds; your breath catches and every instinct says get out. That is the cold-shock response, and it passes. Focus on slowing your exhale, and within 90 seconds it settles into a calm, clear, almost euphoric state. The hardest part is always the start.

Question 22

Can I do contrast therapy, cold then hot?

Accepted Answer

Yes, with the Chiller Pro. It spans 0 °C to 42 °C, so one system does both. A common approach alternates a few minutes cold with a few minutes warm, repeated 2 to 3 rounds. Finish on cold for the alertness lift. Start gently and let how you feel guide the durations. One side note: since going from hot to very cold water and back takes time, proper contrast therapy really needs two tubs, one kept cold and one kept hot.

Question 23

Should I take an ice bath when I am sick?

Accepted Answer

We love the enthusiasm, but give your body a break. When you are run down, your system is already working hard, and an ice bath is extra stress it does not need. Rest, recover, and get back in once you are feeling well again.

Question 24

How cold does the Chiller Pro get?

Accepted Answer

Down to 0 °C. With Rhone's insulation holding the cold, it keeps your set temperature steady between sessions. With 1 HP the Chiller Pro reaches low temperatures quickly too.

Question 25

Can the Chiller Pro heat the water too?

Accepted Answer

Yes. It runs from 0 °C to 42 °C, so the same unit does both cold plunges and hot soaks.

Question 26

How fast does the Chiller Pro cool the water?

Accepted Answer

In our real-world test at 26 °C ambient, it cooled 250 L inside Rhone at 6.5 °C per hour, taking water from 20 °C to 10 °C in under 90 minutes. If the ambient temperature is colder, it cools faster (up to 8.5 °C per hour) or slower in very hot conditions. Chiller Pro's performance is easily sufficient up to 45 °C ambient.

Question 27

How loud is the Chiller Pro?

Accepted Answer

About 60 to 65 dB while actively cooling, similar to a dishwasher, dropping to around 42 dB in pump-only mode. These are our own measured figures.

Question 28

How does the Chiller Pro keep the water clean?

Accepted Answer

Built-in 20-micron filtration plus ozone purification, chemical-free, so most users go weeks, even months, between water changes.

Question 29

Do I control the Chiller Pro from my phone?

Accepted Answer

You can, through the app, for temperature, scheduling, and monitoring. You do not need a phone day to day though, the unit has an onboard touchscreen.

Question 30

How much does the Chiller Pro cost to run?

Accepted Answer

Surprisingly little. Because Rhone's insulation holds the cold, the Chiller Pro barely runs once you are at temperature: roughly €27 a year versus about €400 for a poorly insulated tub.* It draws power mainly while actively cooling, and barely any in standby. Honestly, the lowest running costs come from using the scheduling feature and following the guidance in our manual.

*Based on internal testing; your results may vary with usage, ambient temperature, cooling method, and local energy prices.

Question 31

Can I use the Theralpine Chiller Pro indoors and outdoors?

Accepted Answer

Yes, Theralpine Chiller Pro is designed for both indoor and outdoor use. Its IPX5-rated housing protects against rain and water splashes from any direction, making it suitable for outdoor environments. For optimal performance and long-term reliability, we recommend placing the chiller in a shaded, well-ventilated, and covered location. While IPX5 ensures resistance to splashes and rain, it is not intended for prolonged exposure to extreme weather, standing water / snow, or water submersion. Users are responsible for protecting the unit from such conditions. Improper use or failure to shield the chiller may void warranty coverage in case of damage.

Question 32

Can I keep the Chiller Pro outside in freezing winter weather?

Accepted Answer

If temperatures are below freezing, it's better not to. Water inside it can freeze and expand, which can strain or even damage internal components, so bring the Chiller Pro indoors once temperatures drop below zero. The Rhone tub itself can stay outside without worry.

Question 33

How cold does the Chiller Lite get?

Accepted Answer

Down to 3 °C, properly cold, and Rhone's insulation stores that cold between sessions.

Question 34

How fast does the Chiller Lite cool the water?

Accepted Answer

About 3 °C per hour at 22 °C ambient. Once you are at temperature, Rhone's insulation does the heavy lifting, so the Lite mostly just maintains the cold.

Question 35

How loud is the Chiller Lite?

Accepted Answer

Under 55 dB while cooling, and below 40 dB from a few steps away. That quiet running is its signature, ideal for indoor or noise-sensitive setups.

Question 36

Can the Chiller Lite heat the water?

Accepted Answer

No, the Chiller Lite cools only. Heating up to 42 °C is a Chiller Pro feature.

Question 37

How does the Chiller Lite handle water care?

Accepted Answer

The Chiller Lite has an integrated particle filter that captures larger debris and protects the internal components. You can upgrade it to 20-micron filtration with the optional Filter and Housing Kit. Ozone purification is a Chiller Pro feature.

Question 38

Do I control the Chiller Lite from the app?

Accepted Answer

Yes, both ways. Set the temperature, schedule, and monitor the Chiller Lite from the Theralpine app, or adjust it directly using the controls on the unit itself.

Question 39

Can I keep the Chiller Lite outside in freezing winter weather?

Accepted Answer

If temperatures are below freezing, it's better not to. Water inside it can freeze and expand, which can strain or even damage internal components, so bring the Chiller Lite indoors once temperatures drop below zero. The Rhone tub itself can stay outside without worry.

Question 40

Which chiller should I choose, the Pro or the Lite?

Accepted Answer

It depends on your priorities. The Chiller Pro is built for maximum performance: fast cooling, the coldest temperatures (0 °C), heating and contrast therapy, and hands-off ozone water care. The Chiller Lite is built for the quietest running, a more compact unit, and a lower entry price. For a full side-by-side, see our „Which chiller should I choose?“ comparison.

Question 41

What is the weight and max height capacity for Rhone?

Accepted Answer

Rhone is structurally very strong and built for users up to 150 kg and up to 2 meters tall. The fit gets tighter for very tall people, but even professional basketball players over 2 meters report sitting comfortably. Ground-level entry makes getting in and out easy for most.

Question 42

How does Rhone support safe entry and exit?

Accepted Answer

Rhone is designed with safety and accessibility in mind. Its ground-level entry eliminates the need to climb up or balance on steps, which represents a common risk with many other tubs. Inside, a textured anti-slip floor provides secure footing, even when wet. Unlike many cold plunge products that include elevated bases or slippery internal steps, Rhone prioritizes real-world usability and minimizes the risk of slipping or falling.

Question 43

Is it safe to place Rhone on a balcony or terrace?

Accepted Answer

In most cases, yes. Rhone was purposefully designed with this use case in mind. Its compact footprint and optimized weight distribution help minimize load per square meter. However, since every structure is different, we cannot guarantee compatibility with your specific space. We recommend consulting your building management or a structural engineer to ensure your balcony or terrace can safely support the filled weight (approx. 267 kg at typical water level).

Question 44

How quick and easy is the setup?

Accepted Answer

The setup itself takes only minutes. Place Rhone on level ground, connect your chiller to the two built-in ports with the included hoses, and fill it with a garden hose. No tools, no plumbing, no installation. How quickly it gets cold then depends on your chiller; with the Chiller Pro, for example, your bath is typically cold and ready to use within about 90 minutes.

Question 45

Which electrical connection do I need?

Accepted Answer

A standard household socket is all you need. Both chillers run on normal mains power with a regular European Schuko (Type F) plug, with no special wiring or high-power connection required. A standard extension lead is fine if you need to reach a socket.

Question 46

Do I need ice, or a water chiller?

Accepted Answer

Neither to get started. Rhone's insulation holds the cold very well, so cold tap water can be enough at first. As you progress with cold plunging, tap water alone may no longer be cold enough for the full effect. That is where ice or a chiller comes in. The Chiller Pro delivers precise temperatures from 0 °C to 42 °C with ozone-clean water, and the Chiller Lite cools to 3 °C. Most committed users add one, but the choice is yours.

Question 47

What water temperature range is supported?

Accepted Answer

Rhone works with or without a chiller. With the Chiller Pro you can set any temperature from 0 °C to 42 °C, and the Chiller Lite cools to a steady 3 °C (it does not heat). Without a chiller, you fill Rhone with cold water and fine-tune with ice.

Question 48

Can I precisely control the temperature?

Accepted Answer

Yes. With the Chiller Pro you can set any temperature from 0 °C to 42 °C, to the degree, from the touchscreen or the app. The Chiller Lite cools to a steady 3 °C, set from the app. Schedule it cold for your morning plunge, or with the Pro switch to warm for contrast therapy. Full control, and no guesswork with ice.

Question 49

How cold should an ice bath be?

Accepted Answer

There's no magic number. The key is that it feels uncomfortably cold. That's when the real benefits begin. Most people start between 10 to 15°C, but it all depends on personal tolerance and gradual adaptation. You don't need extreme temperatures to see results. If you are someone who thrives on progress and seeks new challenges, consider adding our water chiller for the ultimate cold plunge experience and precise temperature control.

Question 50

How long should I stay in the ice bath?

Accepted Answer

For healthy beginners, we recommend starting with at least 90 seconds. Focus on controlling your breathing and resisting the urge to get out early. As your tolerance builds, sessions of 3 to 5 minutes are common. Always consult a physician if unsure.

Question 51

How often should I take an ice bath?

Accepted Answer

2 to 4 times per week is a great starting point, with a goal of at least 11 minutes total per week for optimal results.

Question 52

Is it easy to integrate into my routine?

Accepted Answer

Yes, and that is the whole point. Owning an ice bath at home removes the friction and gives you quick cold therapy whenever you need it, no hassle. A session is just 90 seconds to a few minutes, and with the Chiller Pro holding your water at temperature, it is always ready. Plunge before work, after training, or to wind down in the evening, with no ice to haul and no waiting for it to cool.

Question 53

How often should water be changed or filtered?

Accepted Answer

It depends on your setup. Without a chiller or treatment, there is no fixed timeframe; water clarity depends on your location and use, so watch the water itself. Change it when you notice cloudiness, an off smell, or a biofilm forming. With the Chiller Pro's filtration and ozone running 2 to 3 hours a day, water can stay clean for weeks, even months, with regular use. Watch for the same signs to know when it is time.

Question 54

What water care does each chiller include?

Accepted Answer

The Chiller Pro includes 20-micron filtration plus ozone purification, a chemical-free way to keep the water clear for weeks or even months. The Chiller Lite uses an integrated particle filter and can be upgraded to the same 20-micron filtration with the optional Filter and Housing Kit. Ozone purification is a Chiller Pro feature.

Question 55

Do I need to add chemicals or salts to my ice bath water?

Accepted Answer

No. With the Chiller Pro's ozone purification and 20-micron filtration, the water stays clean and clear on its own, no chemicals needed. If you ever want to, mild treatments like a little chlorine are compatible, but they are not necessary. We would avoid essential oils and highly concentrated additives, which can affect material integrity over time. Unsure about something specific? Just ask us.

Question 56

How often do I replace the filter, and what does it cost?

Accepted Answer

About once a month. The 6-Month Filter Bundle for either chiller is €60, roughly €10 a month. Clean filters keep the water clear and protect the chiller.

Question 57

What warranty comes with your products?

Accepted Answer

All Theralpine products include a two-year warranty that covers defects in materials and workmanship. It does not cover normal wear and tear, cosmetic imperfections, or damage from misuse, but if there is a genuine issue, we will take care of it.
