We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

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.

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.

Most saunas give you one room and a door to the cold. The Hele Double gives you the whole sequence. A hot room that seats six around the stove, a glass partition, and a private changing room you pass through on the way out. Hang your robe, cool down, step back in. On a quiet property by water, it becomes the center of the whole evening.
Your walls are double-glazed, mirrored, tempered glass. From your bench you look straight out at the trees or the water. From outside it reads as a mirror, so the room stays private in daylight. The glass carries a UV lamination that birds can detect, and the double pane with an argon layer holds heat about as well as 2.36 inches of solid wood.
The structure is CLT panels and glulam posts under an EPDM roof, the same flat rubber roofing that shrugs off weather for decades. It leaves the Estonian factory fully assembled, shrink-wrapped, cushioned, and crated. On delivery day it is craned or forklifted into place in one piece. The only assembly is setting the chimney, and the ten adjustable legs give you a few centimeters of play to level it on the pad. A patching kit is included for the top lifting-plate holes.
Choose a wood-fired stove or an electric heater. With wood, the room needs no power at all, so it works on a remote site with nothing run to it, and it reaches a deep, hard heat in under an hour from a cold start. If you want lighting and a fan without running a line, an optional solar kit about the size of a lunchbox powers the interior and perimeter LEDs and the ventilation.
The door is the part your hand touches first, and Haljas has refined it across several generations to an aluminum jamb with roller locks that hold firm even when a big throw of water pushes back. A butterfly latch sits inside and a key outside, so no one can lock themselves in. LED strips light the benches inside and run the full perimeter under the roof trim, so the room glows at night and the mirror reads even stronger from outside. A wood stove ventilates itself as it draws. For a full room of five or six, add mechanical ventilation for fresh air through the whole session.
The changing-room bench and the stove can be mirrored left to right, so your main bench faces the view instead of a wall. Choose Aspen for a light interior or Thermo-Alder for a dark one, and add a Juniper ceiling for its aroma and its clean, sharp lines overhead. Thermally modified wood does not swell or shrink through the heat-and-cool cycle, so you avoid the gapping and cracking cedar is known for.
Each Hele Double takes about two hundred production hours and is built to your configuration, then shipped by sea. Only a small number are made each year, so yours is genuinely rare and genuinely yours. Plan on roughly twenty weeks from order to arrival, then install.
The Hele Double can be lifted from above by crane using its built-in hooks, or from below by forklift. It is delivered on a dedicated flatbed trailer.
Tell us your site and how you want to use it, and we will size the heater, plan the foundation from the leg scheme, and walk the whole install with you. For a limited time, if timing works, a Sauna Marketplace founder can be on site for the delivery. Call or text (844) 565-1113.
This is a finished centerpiece, not a kit you wrestle together. Haljas designs and builds every Hele in Estonia, and the Hele glass design is a Red Dot award winner. The interior is furniture-grade with no exposed fasteners, and every unit is inspected panel by panel for a flawless, uniform finish. These are rare in North America. We’ve used the Hele Nano, Hele Single and Hele Double, and we’re big fans. The juniper ceiling option is one of our favorite things about a Hele, for the smell alone.
The first price is the fully assembled sauna, before the heater package and shipping. You choose the heater that suits your setup, and plan for freight to your address, getting it from the truck onto its pad (which is a crane or forklift to set it in place), and your own electrician and a level, load-bearing base. We give you one all-in number before you order, so there are no surprises later, and financing is available through Affirm.
Here is how it goes. First you talk it through with a founder who has installed these, and we size the heater and plan your site. Then you configure your interior and options and we place the order. On delivery day one of us can be on site to help your crew land it, level the legs, set the chimney, and dial everything in. Ask us for current availability: in-stock units ship fully assembled within days, and custom builds take about twenty weeks from Estonia.
We don’t install saunas ourselves, but we have installers and electricians we’ve worked with before, and we can recommend them in most areas. Send us your ZIP code and we’ll check who’s near you. You hire them directly.
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.
Two-year residential and six-month commercial, with full details in the product manual.
