CLIMATE CONTROLLED SAUNA

Climate Controlled Saunas — The Most Scientifically Advanced Home Sauna Available

 

Every sauna heats the air. A climate controlled sauna manages it. Using the Saunum climate control system — the most sophisticated sauna air management technology currently available for residential installation — a climate controlled sauna actively circulates, filters, and balances the air within the cabin throughout the session, mixing the hot upper air layer with the cooler lower air layer, passing it through Himalayan salt crystals, and redistributing it evenly across the entire cabin volume. The result is a heat environment that feels fundamentally different to any other sauna experience — softer, more breathable, more evenly distributed, and more physiologically comfortable at higher temperatures than a conventionally ventilated cabin of the same specification. At The Sauna Company, our bespoke climate controlled saunas are custom-designed and built on-site across London and Surrey, starting from £17,995 fully installed, and they represent the most technically advanced residential sauna build we offer.

 

The Saunum System — What It Does and Why It Matters

 

In a conventional sauna, heat stratifies. The air near the ceiling can be 20°C to 30°C hotter than the air at bench level, and the air at floor level is cooler still. This stratification is manageable in a well-designed traditional sauna — experienced bathers simply position themselves at the right bench height for the intensity they want. But it also means that the cabin is never operating as efficiently as it could, that the heat distribution across the bather's body is uneven, and that the air quality at breathing level degrades more quickly than it would in a properly circulated environment. The Saunum system addresses all of this simultaneously — drawing air from the upper and lower extremes of the cabin, passing it through a bed of Himalayan salt crystals that filter, ionise, and humidify it, and redistributing it evenly throughout the cabin at a consistent, controlled temperature. The effect is immediate and unmistakable — a sauna that breathes as well as it heats, and that remains comfortable and invigorating at temperatures that would feel oppressive in a conventionally ventilated cabin.

 

Bespoke Design, Premium Specification, Engineered to Perform

​

A climate controlled sauna is not simply a standard sauna with a Saunum unit added to it — the integration of the climate control system needs to be resolved at the design stage, with the unit position, the air distribution channels, the salt crystal bed, and the ventilation system all engineered as a coherent whole rather than retrofitted as an afterthought. At The Sauna Company, we are one of the few residential sauna installers in London and Surrey with the experience and technical knowledge to design and build a climate controlled sauna from first principles — specifying the cabin volume, the heater output, and the Saunum unit capacity in relation to each other, and resolving the air distribution geometry within the 3D design before a single panel is cut. Every build incorporates premium Scandinavian timbers, market-leading HUUM or Harvia heaters, and the full Saunum climate control system — integrated invisibly into the cabin structure so that the technology disappears and only the experience remains.

 

For Those Who Want the Very Best Sauna Session Possible

 

The clients who commission climate controlled saunas from us are, almost without exception, people who have already experienced high-quality saunas — either through extensive travel, through a previous installation, or through serious engagement with the research on sauna science — and who have decided that they want the most refined and physiologically effective home sauna session available. They are not paying for a feature. They are paying for a measurably better experience, session after session, for the life of the installation. If that is where your thinking has arrived, call us on 0208 058 0871 or book a free design consultation. We will walk you through the Saunum system in detail, show you how it integrates into a bespoke cabin design, and give you a complete, fixed quote for a climate controlled sauna built around your specific space and vision.

 

Climate Controlled Sauna FAQ's

​

What is a climate controlled sauna and how does it differ from a standard sauna?

 

A climate controlled sauna uses an active air management system — most commonly the Saunum climate control unit — to continuously circulate, filter, and redistribute the air within the sauna cabin during the session, rather than relying on conventional passive ventilation. In a standard sauna, heat stratifies naturally within the cabin, with a significant temperature differential between the ceiling and the floor, and air quality at breathing level degrades as carbon dioxide accumulates over the course of a session. The Saunum system draws air from both the upper and lower extremes of the cabin, passes it through a bed of Himalayan salt crystals that filter and ionise it, and redistributes it evenly throughout the cabin at a consistent temperature. The practical effect is a sauna cabin in which the air is noticeably fresher, more evenly heated, and more comfortable to breathe at high temperatures than a conventionally ventilated sauna of equivalent specification — allowing longer, more comfortable sessions at higher temperatures with less of the oppressive stuffiness that characterises a poorly ventilated cabin.

 

What is the Saunum climate control system and how does it work?

 

The Saunum climate control system is a sauna air management unit developed in Estonia that actively regulates the air environment within a sauna cabin throughout the session. The system works by drawing cabin air through an internal bed of Himalayan salt crystals, which filter airborne particles, release negative ions, and add a controlled level of humidity to the air before it is redistributed back into the cabin through a series of vents positioned at bench level. This continuous circulation process eliminates the pronounced temperature stratification that occurs in a passively ventilated sauna, maintains a consistent and breathable air quality throughout the session, and adds the therapeutic benefits of halotherapy — salt air exposure — to every session without requiring a separate salt wall installation. The Saunum unit integrates with the sauna heater control system and can be managed alongside temperature and humidity settings from a single interface, including via smartphone app in WiFi-enabled configurations.

 

What are the health benefits of a climate controlled sauna compared to a conventional sauna?

 

The health benefits of a climate controlled sauna encompass all of the well-documented benefits of conventional sauna use — improved cardiovascular circulation, reduced blood pressure, accelerated muscle recovery, stress reduction, enhanced sleep quality, and the long-term protective effects on cardiovascular and cognitive health documented in Scandinavian longitudinal research — with several additional benefits attributable to the active air management system. The continuous circulation of fresh, salt-filtered air throughout the session maintains oxygen levels and reduces carbon dioxide accumulation at breathing level, which means sessions feel more comfortable and can be sustained for longer at higher temperatures. The halotherapy effect of the salt crystal filtration bed adds respiratory benefits associated with salt air exposure, including reduced airway inflammation and improved lung function. The even heat distribution produced by the Saunum system also means that the physiological heat stimulus is applied more consistently across the entire body surface, potentially producing a more complete cardiovascular and metabolic response than the uneven heat distribution of a conventionally ventilated cabin.

 

How much does a climate controlled sauna cost in London and Surrey?

 

Climate controlled saunas at The Sauna Company start from £17,995 fully installed, reflecting the cost of the Saunum climate control system itself, the additional design and engineering work required to integrate the unit correctly within the cabin structure, the salt crystal bed, the air distribution system, and the premium sauna heater and timber specification that a build at this level demands. The final price depends on the size of the cabin, the complexity of the Saunum integration, the heater model and output selected, the timber finish, and any additional features such as full-height glazing, chromotherapy lighting, WiFi-enabled controls, or premium bench configurations. As with all of our builds, the quote is fixed and fully itemised following a free design consultation and site survey, and includes a detailed 3D visualisation showing the complete cabin design and Saunum integration before any commitment is made.

​

Can a climate controlled sauna be combined with other sauna types such as infrared or hybrid?

 

Yes — the Saunum climate control system is compatible with a range of sauna heating formats and can be integrated into a traditional Finnish sauna, a hybrid sauna incorporating both infrared panels and a kiuas heater, or a bio combi sauna with a steam generator. The most common configuration is a climate controlled Finnish sauna, where the Saunum unit works alongside a high-output kiuas to produce the most refined version of the traditional sauna experience — full löyly capability, even heat distribution, and continuously filtered salt air throughout the session. A climate controlled hybrid sauna represents the most technically comprehensive home sauna build available, combining infrared recovery heat, traditional Finnish high heat with löyly, and active Saunum air management within a single cabin. The integration of the Saunum system with any heating format needs to be resolved at the design stage rather than retrofitted, which is why we treat every climate controlled sauna as a bespoke engineering project from the outset rather than a standard installation with an add-on unit.
