Luik Ash Outdoor Sauna | Thermory

The Luik Benchmark Ash Outdoor Sauna is a refined outdoor retreat designed for 4 to 5 people, combining Scandinavian-inspired architecture, premium thermally modified wood, and durable outdoor performance. Named after the Estonian word for swan, Luik reflects quiet grace, effortless calm, and a restorative sauna ritual.

Finished in pre-oiled Benchmark Ash with a clean vertical exterior profile, the Luik Ash creates a bold, sophisticated focal point in any backyard wellness space. Inside, smooth thermally modified aspen surrounds the sauna, including the walls and benches, for a sleek, cohesive interior with a warm natural feel.

Built with cross-laminated timber (CLT) subpanels and extra-thick 5.59-inch walls, the Luik is designed for strength, heat retention, and lasting stability in changing outdoor conditions. Its tinted tempered-glass front brings natural light into the sauna while maintaining privacy, and integrated dimmable LED lighting creates a calm, spa-like atmosphere from day into evening.

Delivered as a modular flat-pack sauna, the Luik Ash is designed for DIY-friendly weekend assembly with a few helpers and no hoisting equipment required.
