Thermory 5 Person Luik Series Sauna

The Luik Outdoor Sauna is a 4–5 person modular sauna named after the Estonian word for swan — a symbol of quiet grace on still water. Built for a bespoke, minimalist ritual, Luik pairs a clean vertical exterior profile with cross-laminated timber (CLT) subpanels and extra-thick 5.59" walls for superior heat retention, sound dampening, and structural stability in changing outdoor conditions. A tinted, tempered-glass front brings in natural light while preserving privacy, and integrated dimmable LED lighting carries the mood from day into evening.

Choose your exterior and interior finish below — Kodiak Spruce, with its warm, buttery alder benches, or the Benchmark Ash, a bold pre-oiled exterior with a sleek thermally modified aspen interior — then select your heater package (Harvia, Homecraft, or HUUM).

Why Thermory

Thermory is the only thermally-modified sauna manufacturer of its kind in North America. We heat and steam our Nordic wood to chemically alter it at the cellular level — releasing sugars that attract rot, stabilizing the cell walls against moisture, and locking in dimensional stability that untreated wood can't match. Result: a sauna that doesn't shrink or warp through changing seasons, backed by 25 years of proven rot resistance, and finished with a clean, splinter-free aesthetic. No chemicals. No sealers required. Just wood, perfected.
