Handcrafted in Lithuania and fully insulated with PIR panels, it measures 85\" W × 85\" L × 98\" H and arrives flat-packed for assembly on your own foundation. The heater is sold separately, so you can choose the right one for your site; Celsium specifies at least 9 kW.\u003c\/p\u003e\n\u003ch3\u003eInsulated to Hold Its Heat\u003c\/h3\u003e\n\u003cp\u003eCelsium insulates the walls, ceiling and floor with 5 cm (about 2\") PIR insulation boards, a high-performance rigid insulation that helps the cabin hold its heat outdoors. An EPDM rubber roof covering provides long-lasting weather protection, and the ThermoWood® exterior is thermally modified timber, treated with heat and steam instead of chemicals for stability and resistance to moisture.\u003c\/p\u003e\n\u003ch3\u003eAn Aspen Interior Built Around Finnish Bench Heights\u003c\/h3\u003e\n\u003cp\u003eInside, aspen lines the walls and the benches. The Jonas Classic comes with Celsium's standard bench layout: two straight aspen benches, an upper and a lower tier, each 72.2\" (1,835 mm) long, with seating for up to four. Celsium sets the bench heights to Finnish sauna standards, so heat reaches you evenly and your feet stay comfortably warm. An LED strip is included for soft indoor lighting and is installed on site.\u003c\/p\u003e\n\u003ch3\u003eDaylight Through Bronze-Tinted Glass\u003c\/h3\u003e\n\u003cp\u003eThe front of the Jonas Classic is one large panel of bronze-tinted glass that covers most of the wall, and the full-height 8 mm tempered glass door sits next to it, in the left-hand side wall at the end nearest the glass. The bronze tint warms the view and softens glare, so the cabin feels open and bright during the day.\u003c\/p\u003e\n\u003ch3\u003eFive Exterior Colors\u003c\/h3\u003e\n\u003cp\u003eChoose the ThermoWood® exterior in Beige, Grey, Ebony, Teak or Hazel to suit your home and landscape. Every Celsium sauna is crafted from natural wood, so the final color and grain may vary slightly from the images.\u003c\/p\u003e\n\u003cp\u003eImages are for illustration purposes only. The Jonas Classic comes with its full-height glass door on the left-hand side, and some photos show the door on the opposite side. The color renderings show each exterior finish, and other details in the images, such as the glass tint, interior wood, heater and lighting, may differ from the sauna you receive. The specifications on this page describe what's included.\u003c\/p\u003e\n\u003ch3\u003ePlanning Your Installation\u003c\/h3\u003e\n\u003cp\u003ePlan for a solid, level foundation of at least 86.6\" × 86.6\" (2.2 × 2.2 m). The sauna ships flat-packed and is delivered securely on pallets, with Celsium's step-by-step installation guidelines. Delivery is curbside, with liftgate service available on request; moving the components from the curb to your site is up to you, and you can hire a local contractor for assembly. The heater must deliver at least 9 kW, and a licensed electrician connects it on a dedicated circuit sized to the model you choose. Our specialists pair the heater, control and stones with your cabin and your electrical service. The heater and wall control shown in the photos are sold separately.\u003c\/p\u003e\n\u003ch3\u003eComplete Your Wellness Space\u003c\/h3\u003e\n\u003cp\u003eFor hot-and-cold contrast sessions, pair the Jonas Classic with one of our cold plunges, and add robes and towels for the walk between them.
