Forget AI. The Most Powerful Tool for Team Connection in 2025: A Rooftop Sauna
At Celsium Wellness, we believe that the future of innovation and workplace wellness doesn’t start behind a screen. It starts in heat, silence, and presence. Sometimes, the most powerful conversations happen at +90°C, where steam rises and people leave behind stress, hierarchy, and everyday roles.
That belief led to our latest rooftop sauna project, created in collaboration with Kilo Health, one of Europe’s fastest-growing healthtech companies. Located on the rooftop of their Vilnius headquarters, this is the first Celsium Wellness sauna — and a bold step toward redefining corporate wellness spaces.
Why a rooftop sauna — and why now?
Because modern teams are overloaded with information but starved of real connection. The digital workplace is loud, fast, and fragmented. A sauna at the workplace offers the opposite: heat, calm, and uninterrupted presence. Research shows that regular sauna use improves cardiovascular health, reduces stress, boosts mood, and enhances mental clarity — making it one of the most effective forms of screen-free wellness therapy.
This shift toward social wellness experiences is happening globally.
In Copenhagen and Oslo, floating saunas are used for team offsites and leadership retreats.
In London, urban saunas have evolved into cultural hubs hosting poetry readings, DJ nights, and wellness events.
In the United States, wellness-driven founders are replacing happy hours with sauna sessions — with the sauna market expected to reach $526 million by 2028.
In New York and Detroit, historic buildings are being transformed into modern spaces where business, community, and sauna culture intersect.
The future of workplace wellness
We believe the future of wellness is social, silent, and hot. With Celsium Wellness, we design rooftop saunas and corporate wellness environments that allow teams to reconnect naturally — without pressure, noise, or distractions. Just warmth, water, and genuine human presence.
The Kilo Health rooftop sauna is only the beginning. We’re now partnering with companies, creative studios, coworking spaces, and hospitality brands to bring rooftop saunas, urban wellness installations, and nature-based sauna experiences to more people — in cities, forests, and even floating on water.
