Question 1

What is included with my Rhone purchase?

Accepted Answer

Rhone comes with: An insulated lid; Two built-in water chiller ports (3/4" BSPT female thread); Matching thread caps for both ports. Accessories like a water chiller (with built-in cooling, filtration, and ozone purification), hoses, and filters are sold separately — or included in the Rhone & Chiller Bundle.

Question 2

What is included with my Rhone & Chiller Bundle?

Accepted Answer

The Rhone & Chiller Bundle includes everything you need to get started with cold therapy:

Rhone Tub: Fully insulated Rhone tub; Insulated lid; 2× built-in chiller ports (3/4" BSPT female) with matching caps.

Water Chiller Kit: Premium Theralpine Chiller Pro (1 HP, ozone + 20-micron filtration); 2× 2.5m hoses (16mm diameter, 1/2" BSPT threaded ends); 2× 3/4" to 1/2" adapters with shut-off valves; 4× replacement water filters.

All core components are included to help you plunge, cool, and maintain clean water from day one. Additional accessories may be offered separately.

Question 3

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 4

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 5

What are the dimensions and weight of the 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 6

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 7

How cold should the water 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 10–15°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 8

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 3–5 minutes are common. Always consult a physician if unsure.

Question 9

How often should I take an ice bath?

Accepted Answer

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

Question 10

What temperature range does Rhone support?

Accepted Answer

Rhone can be used with or without a water chiller. Paired with the Theralpine Chiller Pro, you can plunge as cold as 0°C or warm up to 42°C. In regions with harsh winters, we recommend ensuring the water doesn't freeze completely. While Rhone is highly insulated, prolonged sub-zero temperatures can cause the water to freeze into a solid block. This prevents use and may also place unnecessary stress on the material due to ice expansion.

Question 11

Do I need ice or a chiller?

Accepted Answer

No, you don't need ice to take an "ice bath." In fact, water chillers often cool the water more effectively than adding ice to tap water. Whether there's ice floating or not says little about the actual temperature. Ultimately, the premium setup is a well-insulated tub like the Theralpine Rhone paired with our high quality Chiller Pro. It gives you full control over water temperature, keeps your water clean longer, and helps you level up when you're ready. That said, you can still get excellent results using Rhone with just cold tap water, adjusting the temperature to your preference with added ice. Thanks to its industry-leading insulation, it keeps water cold for multiple days, even without a chiller.

Question 12

How long does the Theralpine Chiller Pro take to cool down my ice bath?

Accepted Answer

In our real-world test at 26 °C ambient temperature, it cooled 250 L of water inside Rhone at a rate of 6.5 °C per hour. Most users typically start with water around 20 °C and cool it down to about 10 °C, which can be achieved in under 1.5 hours.

Question 13

How often should water be changed or filtered?

Accepted Answer

No chiller, no water treatment: If you're not using a chiller or any form of treatment, we recommend changing the water every 2–4 days, depending on use and environmental factors.

No chiller, with water treatment: With basic chemical treatment (e.g. small amounts of chlorine or hydrogen peroxide) and no chiller, you can typically extend water use beyond 7 days.

With chiller (filtration + ozone purification): When using the Theralpine Chiller Pro with integrated filtration and ozone purification, water can typically stay clean for up to 4 weeks or more with regular use. We recommend running the filtration system for at least 2–3h per day to maintain optimal water quality.

Question 14

What filtration and water-treatment options are available?

Accepted Answer

The Theralpine chiller uses a high-precision 20-micron filter to remove hair, debris, and fine particles from the water. It also features ozone purification, a chemical-free method that neutralizes bacteria and supports long-lasting water clarity.

Question 15

Can I use chlorine, salt, Epsom salts, essential oils, or other additives?

Accepted Answer

Yes, Rhone and the Theralpine chiller are compatible with fresh water, chlorine, Epsom salts, and low-salinity saltwater. However, we don't recommend essential oils or highly concentrated additives, as they may affect material integrity over time.

Question 16

What is the weight and max height capacity for Rhone?

Accepted Answer

Rhone is structurally very strong and supports users up to 150 kg and over 2 meters tall. While the fit is tighter for very tall individuals, professional basketball players above 2 meters have reported feeling comfortable. Ground-level entry makes it accessible to most users.

Question 17

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 18

Is it safe to place the 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 19

What warranty comes with Rhone?

Accepted Answer

Yes! All Theralpine products include a two-year limited warranty that covers defects in materials and workmanship. This doesn't cover normal wear-and-tear, cosmetic imperfections, or damage from misuse but if there's a genuine issue, we'll take care of it.
