An off-grid sauna runs entirely on firewood — no electrical hookup, no gas line, no generator required. If your property has trees and a flat spot to place a sauna, you have everything you need. These saunas are designed for remote cabins, lakefront properties, backyards without dedicated circuits, campgrounds, and anywhere else where grid electricity is unavailable, impractical, or simply not part of the plan. Every sauna in this collection uses a wood-burning stove to produce heat, giving you the most authentic traditional sauna experience: real fire, real steam from water poured over hot stones, and the sound of crackling wood.
For a detailed breakdown of off-grid heater options (including gas-powered and low-power electric alternatives), read our Best Sauna Heaters for Off-Grid Cabins & Remote Locations guide.
These are complete outdoor sauna structures that ship as kits for on-site assembly. Each includes the cabin, benches, a wood-burning stove, chimney, and sauna stones — everything you need except firewood. They're built from weather-resistant wood species designed for year-round outdoor exposure without additional weatherproofing.
Dundalk LeisureCraft — Handcrafted in Canada from Eastern White Cedar or Canadian Timber (thermally modified). Dundalk offers the widest range of off-grid-ready shapes and sizes:
Barrel Saunas — The barrel shape is inherently efficient for wood-fired heating: the curved walls concentrate heat toward the center and eliminate wasted corner space. Dundalk barrel saunas are available in multiple lengths (6', 7', 8') to accommodate 2–6+ people. Many models include a porch overhang for storing firewood and cooling off between rounds. Cabin Saunas — Traditional rectangular cabins with more interior space, flat walls for easy bench layout, and a classic look. Models include the Granby (2–3 person), Georgian (6 person with porch), and Kota (8 person). The Georgian's covered porch is particularly useful for off-grid setups where you want a sheltered area for firewood storage, a cold plunge tub, or a changing area. Pod & Luna Saunas — Distinctive curved-roof designs. The Luna features a rounded, tunnel-like shape that heats efficiently. The MiniPOD is a compact 7'×7' footprint ideal for smaller properties.
SaunaLife — European-designed outdoor saunas with a Scandinavian minimalist aesthetic. SaunaLife offers barrel saunas and their signature Cube series with clean-lined, modern architecture. Their off-grid models pair with wood-burning stoves for fully electricity-free operation. The Model G2 (4-person) and Model G4 (6-person) cabin saunas are popular off-grid choices.
True North Saunas — Handmade in Ontario, Canada. True North builds barrel saunas and cabin saunas designed to withstand harsh Canadian winters. Their Schooner barrel sauna and cabin models are purpose-built for remote, cold-weather installations where durability matters most.
Portable saunas take off-grid a step further — not only do they need no electricity, they need no permanent structure. Set up in minutes, pack down into a travel case, and bring your sauna to the lake, the campsite, or a friend's backyard.
Firefly Sauna Tents — The Firefly Spark is a pop-up sauna tent that heats to over 200°F in 20 minutes using a portable wood-burning stove. The tent pops up with a hub design (no poles to assemble), packs into a compact travel case that fits in a car trunk, and uses insulated 420D Oxford quilted fabric for heat retention. Available as the Spark Basic Kit (tent + stove) or the Spark Full Kit (tent + stove + folding bench + sauna rocks + accessories — everything you need for a complete session). The Dome is a larger tent for families or groups. Firefly also sells the Northwoods portable wood-burning stove separately (made in the U.S.) for use with any compatible tent or structure.
Firefly tent saunas are the lowest-cost entry point for off-grid sauna bathing — a fraction of the price of permanent wood-fired structures — and they're the only option in this collection that you can take with you when you move.
The defining requirement is a wood-burning stove instead of an electric heater. Wood-burning stoves produce heat entirely from combustion — no wiring, no breaker panel, no electrician. Beyond the stove, there are a few practical considerations for off-grid sauna installations:
No foundation required — Most outdoor sauna kits sit on a level gravel pad, concrete pavers, or a simple wooden platform. No poured foundation or permanent construction needed. Chimney ventilation — Wood-burning stoves require a chimney that exits through the roof or wall. Every permanent sauna kit in this collection includes the chimney. For portable tent saunas, the chimney exits through a heat-shielded port in the tent fabric. Water source — Traditional sauna bathing involves pouring water over the hot stones to create steam (löyly). You'll want a water source nearby (well, lake, hose, or simply a filled bucket). This isn't required for the sauna to function — it just makes the experience better. Firewood — Plan for approximately 15–30 minutes of firing time before your first session and periodic feeding during longer sessions. Dry, seasoned hardwood works best. Many off-grid sauna owners source firewood from their own property.
If you have reliable electricity at your sauna location, an electric heater is more convenient — push a button (or tap your phone with a WiFi-controlled heater) and the sauna heats itself. No firewood to split, carry, or store. No ash to clean out. No chimney to maintain.
But many people choose wood-fired even when electricity is available because the experience is fundamentally different. The crackle of the fire, the ritual of tending the stove, the smell of burning wood, and the radiant heat from a real flame create an atmosphere that electric heaters simply cannot replicate. For purists and those seeking the most traditional sauna experience, wood-fired is the goal — off-grid capability is just a bonus.
Not for heating — the wood-burning stove handles that entirely. Some sauna kits include optional electric lighting or ventilation fans, but these are not required for operation. You can light a wood-fired sauna with nothing but firewood and a match. If you want interior lighting, battery-powered LED lanterns or solar-charged lights work well as off-grid alternatives.
Typically 30–60 minutes to reach full operating temperature (170–200°F), depending on the sauna size, outdoor temperature, and stove model. Portable tent saunas like the Firefly heat faster (around 20 minutes) because the enclosed volume is smaller. Start the fire, load the stones, and the sauna will be ready by the time you change and prepare.
In some cases, yes — but it requires proper chimney installation, fire-rated wall and floor protection, and appropriate safety clearances. This is a significant modification. If you're buying a new sauna specifically for off-grid use, we recommend choosing one from this collection that's designed for wood-burning from the start. If you need a wood stove for an existing structure, browse our wood-burning stoves and stove packages (which include chimney kits and protective bedding).
We carry gas-powered outdoor saunas that run on propane — another off-grid option if you prefer not to manage firewood. Gas heaters offer push-button ignition and more consistent temperature control than wood stoves, but they require a propane tank and don't provide the same fire-tending ritual. Our off-grid heater guide covers the pros and cons of each off-grid fuel type in detail.
