Two rooms, one timeless ritual. You step out of the heat into your own changing room, then back to the cold, without leaving your backyard. The Haljas Hele Double gives seven people a hot room and a private changing room joined by a glass partition, all wrapped in double-glazed mirrored glass that reads as a mirror from outside and a clear view from your bench.
It arrives fully assembled, protected in a wooden crate, lifted into place by crane or forklift, and ready to enjoy the same day. It is built to last generations on an EPDM roof, with floor drains and thermally modified wood that will not gap or crack the way cedar does.
For a limited time, if the timing works out, one of Sauna Marketplace’s founders can be on site for your delivery to help it land right.

PLAN THE WHOLE SAUNA
Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
Shop sauna heaters →Explore indoor and outdoor saunas when you are planning beyond one component. Starting with the room makes heater size, controls, and accessories easier to get right.

Both. You can choose a wood-fired stove (the Cozy 12 SW-TW is the standard, most durable option) or an electric HUUM Hive heater. With wood, the room needs no electricity at all.
The mirror is not a tint or a stick-on film. Haljas uses Mirastar glass by Saint-Gobain: clear float glass that goes into a vacuum chamber where a fine layer of metal-oxide particles is deposited onto it by magnetron, forming an extremely thin, even mirror coating. On the double-glazed walls that coating sits sealed between the two panes, so it cannot be scratched, cleaned off, or oxidized from either side, and it gives you a clear view out while the walls read as a mirror from outside in daylight. Only the single-pane door carries its coating on a surface, so wipe it with a soft cloth or sponge as the manual says.
Seven across the two rooms. The hot room seats six comfortably around the stove, and a separate changing room adjoins it through a glass partition.
It arrives fully assembled in a wooden crate and is lifted into place by crane (built-in roof hooks) or forklift. The only on-site assembly is setting the chimney, and ten adjustable legs level it on the pad.
A flat, load-bearing surface such as a poured concrete pad built to the leg layout in the install manual. The adjustable legs give a few centimeters of leveling play. Confirm the spot meets local building and fire code.
Yes. A wood-fired Hele Double works with no power at all. The lighting, ventilation, and audio together draw about 0.25 kW and can run off an optional solar kit.
Aspen or Thermo-Alder interior, a Juniper ceiling, ribbing between the sauna and changing room, a ventilated skirt to hide the feet, a second changing-room bench, and a concealed Bluetooth audio system.
It is built to order. Production is targeted for the end of August, then roughly a month at sea plus port and customs clearance, so plan on an early-fall arrival.
