Sauna + Cold Plunge Combo Survey: Why More Venues Are Adding Ice Baths To Heat Spaces

In light of the continued growth of the global heat wellness industry in 2026, it is evident that the industry is transitioning. Many establishments that have offered only sauna treatment are now embracing the addition of cold plunge pools, thus creating the experience of temperature contrast – an experience which covers the concept of 'hot sauna + cold plunge' altogether. We have managed to provide our survey thanks to our visits to 47 established brands then using this concept in North America, Europe, and East Asia, and communication with over 2000 customers visiting these establishments for the experience in the third quarter of 2026.
Cold Plunge Usage is Transitioning From "Optional Add-On" to "Core Standard Feature"
While cold plunges were viewed as something used mainly by sports-related venues offering recovery treatments, now it is evident that it has become an integral part of the experience provided in sauna facilities. Thus, the traditional sauna experience consisted of high-heat sauna, and people had to follow the principles of sweating, resting, and rehydrating until exit; with the cold plunge being usually omitted or used as a means for convenience by using cold-water containers in the corner.Several acclaimed companies which used to only provide sauna services have engineered retrofits to make cold bath zones in the last one year. This change should not just be underestimated as a whim, since it is an intention of the brands based on certain customers' needs, structure of their income and ability to keep afloat for the long term.
Consumer Requirement: Replacing "Simple Relaxation" with "Complete Revitalization"
The survey showed that the major impetus for venues making these changes is the new habits of the average consumer. Over 72% of 2,000 survey respondents confirmed that a basic sauna session is not enough anymore. People are no longer happy walking away from the sauna with a simple warm shower after they have sweat. They want an all-inclusive approach to wellness.
A respondent from Portland said: "I always felt warm and relaxed after a sauna session, but it was always lacking something. Only after my first experience of having a cold plunge immediately after the sauna I understood how much more invigorating it is". The same comments come from the audience of professional athletes, since 83% of respondents from those who go to gyms indicate that hot-cold contrasts facilitate recovery of muscles after a workout decreasing soreness significantly the day after.More than 60% of office workers claimed that hot and cold stimulations lead to the vasoconstriction and vasodilation process while being able to release the stress accumulated during the week. After that, they experience not only increased concentration but also much higher quality of sleep as compared with using the sauna only.
Deep Operational Logic For Venues: More Repeat Visits And Bigger Revenue Limits
In the case of physical venues, the main thing that has been introduced with cold plunge areas is an increase in the number of repeat visits. According to survey data, venues that offer a sauna alone have 1.7 repeat visits a month per person. Meanwhile, venues with hot-cold experiences achieve 3.3 repeat visits per person per month, which could be almost doubling the previous number. The main reason for such a difference is a possibility of gradual development in the combination of experiences. For first-time visitors, staying in a cold plunge may mean that they are able to be there for just a minute.
At the same time, the combo format considerably broadens the scope of a venue's possible revenue.The addition of cold plunge options enables venues to create a significantly more versatile product range, comprising packages catering to different customer categories such as "hot-cold intro packages for novices," "restoration-for-athletes routines" for fitness enthusiasts, and "deep relaxation package" for the stressed. The total amount spent on every package may differ by as much as 30%–80%. Apart from product packages, many brands also introduce supplementary services related to the combo experience, such as electrolyte replenishment, recovery massages, magnesium salt treatments, etc., which considerably increases their revenue per customer.
Even more significantly, the hot-cold combo experience naturally fits into the concept of social sharing. It has been discovered that social media posts about completion of a "full hot-cold cycle challenge" get 2.7 times more engagement than plain sauna check-ins. This inherent shareability contributes to the venues' massive media presence. Therefore, this innovative experiential offering allows businesses to reduce their customer acquisition costs substantially.
The Future Of The Industry: Contrast Therapy Will Become The Core Standard For Next-Gen Heat Spaces
During the research, we have noted that the ever-popular sauna-and-cold plunge combo has become a not too strong competitive advantage of the companies operating in the wellness sector. And it has resulted in the evolution of the different layouts and service process around the concept of temperature contrast. Some spas have built a full cycle of "using hot sauna – steam room – transition rest – going to cold pool – taking warm magnesium bath," thus ensuring that temperature changes are carried out in a scientifically safe way. Other companies have created pools with differently cold water ranges, thus dividing them into different groups, ranging from simple 15°C for beginners to challenge 3°C for skilled users.
Experts estimate that in the coming three years, the hot-cold treatment concept will change its status from a trend to an industry standard all around the world.
