Weekly Roundup: Five Stories That Shaped the Sauna World This Week

It was one of the busiest weeks in recent sauna industry memory. Here are the five stories that mattered most.

1. Harvia Posts Record Q1 Revenue

Harvia reported Q1 2025 revenue of EUR 52 million, up 22.7% year-over-year, its strongest quarterly growth since the post-pandemic surge. The ThermaSol steam technology acquisition (closed July 2024) is the primary growth driver. See the full earnings timeline and stock chart in our Harvia News hub.

2. U.S. Tariff Pressure on European Sauna Imports

Broad EU tariffs and Section 232 timber duties are raising costs on Finnish and Baltic sauna products entering the U.S. market. Distributors are recalculating pricing models as cumulative duties increase landed costs across heaters, controls, and thermally modified wood.

3. Outdoor Sauna Demand Keeps Climbing

Barrel saunas, cabin saunas, and custom outdoor builds continue to be the fastest-growing segment of the North American residential market, driven by post-pandemic outdoor living investment and social media visibility.

4. HUUM Standardizes Air Tunnel Across HIVE Line

Estonian manufacturer HUUM has made its internal air tunnel a standard feature across all HIVE models, an engineering upgrade that improves heat-up time and extends element lifespan by shielding elements from direct stone weight.

5. Equinox Expands Thermal Wellness Offerings

The luxury fitness brand is upgrading sauna and cold plunge facilities across multiple flagship locations, signaling that thermal wellness is becoming a core competitive differentiator for premium fitness operators.
