✓ Required for: HUUM Hive 12kW, 15kW, and 18kW
HUUM UKU Extension Box for Sauna Heaters Over 10.5kW: The required component for HUUM Hive commercial models at 12kW, 15kW, and 18kW
The HUUM Hive 12kW, 15kW, and 18kW carry a higher electrical load than the standard UKU controller can handle alone. This extension box manages that load. Required for all three commercial Hive configurations.
Order it with the heater — discovering it's missing on installation day stops the project.
Why Buy From RecovAthlete
We're an authorized HUUM dealer. We confirm which extension box your Hive model requires.
Not sure which box you need? Call 866-861-6317 — we confirm in one minute.
"The Hive 12kW, 15kW, and 18kW require this extension box — not the standard 9kW+ version. Confirm before ordering."
Best For
- HUUM Hive 12kW, 15kW, and 18kW buyers
Not Ideal For
- HUUM Hive 6kW, 9kW, or 10.5kW (use the standard 9kW+ extension box)

What You're Getting
- Required for commercial Hive models — order it before installation day.
