# Brightcrystal-Shaped Saunas Lithium Crystal Sauna Transforms a Former Industrial Site By Amy Duong | Published 2026-08-11 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/lithium-crystal-sauna References: [yankodesign](https://www.yankodesign.com/2026/08/10/sweden-built-a-pink-crystal-sauna-on-a-toxic-wasteland/)  Lithium Crystal Sauna is a public art installation and [functioning sauna](https://www.trendhunter.com/trends/round-about-baths) by Bigert & Bergström located within the WasteLand climate action park in Skellefteå, Sweden. The faceted structure is clad in pink titanium-coated mirror steel shaped after the geometry of a lithium crystal, reflecting the surrounding forest, river and sky. Inside, the sculptural exterior transitions to an interior lined with alder and heartwood pine, with flint, olivine stones, copper, glass and LED elements completing the space.

The installation is powered by [standalone batteries and electric vehicle energy](https://www.trendhunter.com/trends/thermasol) as part of the Vehicle-to-Sauna project developed with Skellefteå Kraft. The system explores vehicle-to-grid technology that enables electric vehicle batteries to supply power to both the sauna and the surrounding park. Installed on a remediated industrial site, the project connects public architecture, renewable energy infrastructure and environmental restoration through a fully operational battery-powered sauna.
