Maintain perfectly balanced sauna humidity with the Saunum AutoLeil Automated Water Dispenser, bundled with the required Pre-Bent Pipe for proper installation and performance.

AutoLeil automatically dispenses water onto the heater to create consistent, comfortable steam—eliminating the need for manual ladling. Controlled via the Saunum Leil control panel, users can select preset steam profiles or schedule humidity so the sauna is ready with ideal moisture at your chosen time.

The included Saunum Pre-Bent Pipe ensures correct airflow and water delivery while simplifying installation across different sauna layouts. This component is required for AutoLeil operation.

Designed for both private and commercial saunas, this complete set delivers intelligent, hands-free steam control for a more refined sauna experience.
