Saunum Auto Leil - Sauna Water Dispensing Unit
In a good sauna humidity is just as important as temperature. Saunum AutoLeil is an additional device for the heater that automatically throws water on it and helps you control the humidity in the sauna room.
Saunum AutoLeil is designed for Saunum heaters and is controlled through the Saunum Leil control unit. With the Saunum Leil control panel, you can pre-set 3 different types of steam and enable the use of AutoLeil.
AutoLeil can also be set to ensure that the sauna user enters a comfortably moist sauna room at the designated time. When the sauna room is heated to the desired temperature, AutoLeil ensures water dispension to the heater according to desired settings
The AutoLeil kit also includes a button with LED lighting for throwing water in the sauna room. It is also possible to turn automatic water throwing on or off with this button while in the sauna. The length of one water dispensing cycle is set to 30 minutes by default. It can be changed up to 12 hours, for example, for public saunas. Water can be taken from any household tap.

Shipping & delivery
Shipping cost: Shipping is charged by the total weight of your order. This item on its own ships for $65 within the contiguous US, and the exact amount for your whole order is shown at checkout before you pay.
Most in-stock orders ship within 3–5 business days of confirmed payment, and delivery is typically 5–15 business days after shipment. Made-to-order saunas and custom-configured rooms need production time on top of that, which we confirm before the order is released. We ship within the contiguous United States.
Large items ship LTL freight on a pallet, delivered curbside — to the curb or the end of your driveway, often from a trailer up to 53 feet long. Curbside does not include unpacking, assembly, installation or electrical connection. The carrier calls to book an appointment and someone must be there to receive the shipment. Tell us at the time of order if access is limited — narrow or rural roads, steep driveways, gated communities — and ask for liftgate service if you have no dock or forklift.
Inspect the shipment before the driver leaves and before you sign. Count the cartons and pallets against the paperwork, check glass doors and panels, write any damage or shortage on the Delivery Receipt, and photograph it. Email info@plungeintosaunas.com within 48 hours of delivery with your order number, photos and the noted receipt — the same window covers concealed damage and missing items. Keep the packaging while a claim is open.
Cancellations & returns
Cancel before the order has been submitted for fulfillment and it is refunded in full — email info@plungeintosaunas.com with your order number. After that point manufacturer, carrier, return-freight or restocking fees may apply. Every return must be approved by us in writing first: products ship from different manufacturer warehouses, so the correct return address varies, and anything sent back without authorization may be refused.
Return requests are made within 30 days under our general policy; some brands run that window from the date of purchase rather than delivery. Items must be unused, uninstalled, never heated or filled, complete in their original packaging and in resalable condition. Restocking fees run up to 25% depending on the manufacturer, while Harvia, HUUM, SaunaLife, Saunum, Narvi, ThermaSol, Delta, Kohler and Mr. Steam charge no restocking fee at all, only a re-boxing fee of roughly $20–$50 if the original packaging does not come back intact. On a change-of-mind return you pay return shipping and the original outbound shipping is not refunded.
If the item arrived damaged or a manufacturer error is at fault, return shipping is covered for you. Custom, made-to-order and special-order items already in production, clearance and open-box items, heaters that have been wired or fired, tubs and generators that have been filled, assembled or heated rooms, opened consumables and all Canadian Timber Collection products cannot be returned. Ask us before you buy if you are unsure.
