„Ilmaa is the sweet spot – we have a vestibule and a panoramic window without the sauna taking half the garden. App control is a game-changer.”
Questions about this model
How does Ilmaa differ from Vetta?
Ilmaa is shorter (3.45 m instead of 5 m) with a smaller, minimalist vestibule. The cabin still seats 4–6 people, and the panoramic window opens onto the garden.
Is the vestibule heated?
The vestibule shares full wall insulation and cabin heat. Optionally we install a 230 V electric radiator with thermostat.
What power supply is required?
The HUUM DROP 9 kW heater needs a 400 V supply (3×16 A). Lighting and sockets in the vestibule run on a separate 230 V circuit.
Can I control the sauna from my phone?
Yes – the HUUM UKU Wi-Fi controller is standard. Set temperature and start time from the app.
