About the HUUM STEEL
Industrial power, clean form
The HUUM STEEL is the workhorse of the HUUM lineup. Its stainless grid column holds a large stone load with direct element contact — delivering steady, enveloping heat for traditional sauna rooms that demand consistent performance. Floor-standing and bold, the STEEL suits larger spaces where output and stone volume matter most. All models pair with HUUM's UKU control suite for precise temperature and scheduling.
