Description
The Celsium Jonas Classic is a square, modern outdoor sauna for four to six people, from Celsium's fully insulated Jonas line. PIR insulation in the walls, ceiling and floor helps it heat efficiently and hold temperature through cold weather.
Two tiers of aspen benching run the width of the room behind a large bronze-tinted glass front, and a full-height tempered glass door opens on the left side. Thermowood clads the exterior and indoor LED lighting comes installed. Jonas saunas are handcrafted by Celsium in Lithuania; this unit is in stock at Celsium's U.S. warehouse in Illinois.
Before you order: the heater is not included. Buy a U.S.-spec Harvia or HUUM sauna heater rated 9 to 11 kW, and have a licensed electrician install it; Celsium confirms the right heater model for your sauna. The sauna also needs a solid, level foundation of at least 86.6 × 86.6 in (2.2 × 2.2 m). Installation is not included; you can assemble the sauna yourself and the warranty stays valid.

Celsium Shipping, Delivery & Returns
Our standard Shipping Policy and Return and Refund Policy cover this product. Because it ships by freight directly from Celsium, some terms differ, and where they differ, the terms below govern.

- Timing: this sauna is in U.S. stock. We will confirm the ship date with you after you order.
- It arrives on a pallet of about 2,000 lb, with step-by-step installation guidelines. Plan the path from the curb to the site, and the people or equipment to move the sections, before delivery day.

- Only an unopened sauna may be returned, if you request it within 30 days of delivery. Once the packaging has been opened, or the sauna assembled or used, it cannot be returned.
