Most wall-mounted sauna heaters need 8 to 12 inches of clearance. The HUUM Steel needs 2 inches. That is not a minor difference — it is the reason the Steel exists.
Available in 3.5kW (Mini), 6kW, 7.5kW, 9kW, and 10.5kW for saunas where wall clearance is the deciding factor. Same SGS-certified build quality as the rest of the HUUM lineup, in the slimmest profile available.
Why Buy From RecovAthlete
We're an authorized HUUM dealer who sizes heaters for customers every week. If wall clearance is your constraint, we'll confirm the Steel fits your space before you order.
Give us your wall dimensions and we'll verify fit in minutes. Call 866-861-6317.
"The HUUM Steel's 2-inch wall safety clearance is the tightest in the HUUM lineup — the answer for saunas where a standard heater simply won't fit."
