Harvia Block Custom allows you to shape a sauna that integrates seamlessly into your interior architecture. Based on the clean and structured Block concept, the cabin can be configured with one or two glass corners for a more open spatial experience.
Brushed thermo alder forms the structural foundation of the cabin. Through thermal modification, the wood achieves improved stability and a rich, natural tone that enhances both durability and visual depth. You can mix and match panels and interior details to create a refined, personal aesthetic.
The 30 mm high-performance PIR insulation supports efficient heat retention while maintaining slim wall dimensions. This ensures stable performance and consistent warmth.
Each custom Block cabin is designed and built in Finland, carefully handcrafted and test-assembled before delivery.
Select the heating solution that matches your sauna preference — traditional Finnish electric, pillar heater or combi version. The Fenix touch control panel and optional MyHarvia connectivity provide intuitive modern operation.
Block Custom is a sauna where architectural precision and authentic heat come together.
