This insane pink crystal sauna just rose from Sweden’s industrial ashes

In a world where architecture so often plays it safe, artist duo Bigert & Bergström have delivered something delightfully otherworldly. They present us a geometric, metallic-pink crystal sauna that looks as though it crashed down from outer space into northern Sweden.

Titled the Lithium Crystal Sauna, this striking structure isn’t just an exercise in futuristic sculpture. It is the inaugural permanent installation of the WasteLand Climate Action Park in Skellefteå.
The site, formerly home to the Scharin pulp mill, spent more than a century suffering severe chemical contamination before undergoing 17 painstaking years of soil remediation.
Where toxic emissions once dominated, a surreal beacon of community, wellness, and reflection now stands.

The Power of Paradox
Rather than sweeping the land’s industrial trauma under the rug, Bigert & Bergström leaned straight into its contradictions. The sauna’s faceted form mimics the atomic geometry of a lithium crystal, serving as a deliberate nod to the double-edged sword of the green energy transition.
Lithium powers our electric vehicles, battery grids, and fossil-free dreams, yet its extraction carries massive environmental costs. Placing this symbol on a rehabilitated industrial site creates a poetic, thought-provoking tension.

To bring the digital design to life, 280 asymmetrical prisms were laser-cut with pinpoint precision and clad in titanium-coated mirrored stainless steel.
The shimmering pink hue was achieved through a vacuum evaporation process, creating a facade that shifts dynamically with the northern light. Leaning back at a four-degree tilt, the crystal appears to be actively emerging from the earth.

Ancient Rituals Meet Future Tech
Step across the hexagonal deck of local heartwood pine and push open the glazed doorway, and the hyper-futuristic exterior instantly gives way to a warm, sanctuary-like timber interior.
Lined with rich heat-resistant wood veneer over a spruce framework, the inner chamber takes inspiration from prehistoric cave shelters, the ultimate human retreat. Up to 12 bathers can gather on custom alder benches around a central cage of Normandy black flint and 260 kilograms of heat-retaining olivine stones.


Even the heat source tells a story: the sauna utilizes a custom heater powered by green electricity stored in batteries or electric vehicles.
Remarkably, the heater’s physical silhouette is shaped after a 2.5-million-year-old stone chopper, mankind’s earliest known tool.

Reflection in Every Sense
The exterior’s mirrored pink finish reflects the surrounding river, forest, and returning flora, alongside the scars of a landscape reshaped by human intervention.
It stands as equal parts art installation, historical monument, and public sanctuary: a space designed to strip away social barriers, warm the body, and spark crucial conversations about our changing planet.

Bigert & Bergström have crafted far more than a place to sweat out toxins. They have given us a captivating vision of how art and industrial healing can merge, proving that even from our most polluted pasts, remarkable new ecosystems can emerge.

Bold, beautiful, and quite probably functional design.
