A Finnish sauna is a dry sauna: temperature 80 to 100 °C, humidity up to 20 per cent, and steam from water poured over hot stones. The range includes wooden saunas for 2 to 8 people — for the garden and for indoors — with either a wood-burning or electric stove, from €3,329. Delivery is included in the price, and on models that arrive as a finished unit so are installation and commissioning.
A Finnish sauna is a dry sauna: 80 to 100 °C, humidity under 20 % and a short burst of steam from water poured over hot stones. The range covers wooden saunas for 2 to 8 people — for the garden and for indoors, for a house, a cabin or guest accommodation — with a wood-burning or electric stove, from €3,329. Delivery is included, and on models that arrive as a finished unit so are installation and commissioning.
A Finnish sauna works with dry, hot air. The sauna stove heats the stones, they radiate heat through the whole cabin, and pouring water over them creates a short wave of steam — löyly. The temperature stays between 80 and 100 °C at humidity under 20 %; it is that low humidity which makes such heat bearable.
The models in this category are free-standing structures with their own roof and shell, so they are not tied to a single use. They serve equally well as a home sauna at a family house, in a cabin let to guests, in a guesthouse, in accommodation facilities and in a wellness operation open to the public. Capacity is 2 to 8 people depending on the model and layout: the smallest cabins for two, larger ones with an entrance hall, a covered terrace or a shower zone. Alongside the garden models the range also includes indoor saunas for installation in an existing room in a house or a flat. The smallest model, Nordic Pod, has a 120×210 cm footprint; the largest, Aurora Grand, 300×700 cm.
The Finnish saunas in the range differ in the shape of the structure — that decides how much space the sauna takes and what fits into it besides the cabin.
| Type | What defines it | Capacity | Price from |
|---|---|---|---|
| Barrel | cylindrical shape, smallest footprint, fast warm-up | 4–6 people | €4,825 |
| Cube | straight walls, fully usable interior | 2–8 people | €3,329 |
| Igloo | arched structure with an entrance hall | 4–8 people | €6,577 |
| Modular | cabin with a shower zone in one unit | 6 people | €7,729 |
| Cabin | sauna with an entrance hall or a covered terrace | 6–8 people | €7,469 |
| Panoramic | glazed front wall | 6–8 people | €7,819 |
A wooden sauna in spruce comes at the base price and has a light, natural shade. Thermowood is heat-treated timber that holds its dimensions better under sharp swings of temperature and humidity, and has a darker, warmer tone — with year-round use that is a difference you see after some years.
Benches and interior cladding use lime, aspen or abachi — timbers with low thermal conductivity that do not burn to the touch at 90 °C.
An electric stove at 8 or 9 kW is run by thermostat and timer, so the sauna is hot at the time you set — it does need a 400 V supply. A wood-burning stove up to 22 kW needs no power supply and gives stronger löyly, but it has to be stoked and it needs a chimney. Both are available on almost every garden model — you pick them in the configuration, not by choosing a different product. Indoor saunas are always heated electrically.
Wall thickness is 42 to 200 mm depending on the model; roof and floor carry 100 mm of mineral wool. The interior lining is a Tatra profile, the outer shell sits on 12 mm OSB board. Roofing is supplied as asphalt shingle, torch-on bitumen or sheet metal; doors and glazing are toughened glass 6 and 8 mm thick. Benches are single-tier or two-tier depending on the model.
Prices including VAT start at €3,329 for a two-person sauna and reach €36,321 for the largest set with an entrance hall and terrace. Saunas are sold directly from this category: confirm the configuration in the configurator or through an enquiry, then a deposit follows and delivery in 4 to 12 weeks. The price includes insulation, delivery to the place of destination in Slovakia, Czechia and Hungary, a 2-year warranty and our 4-year service. On models that arrive as a finished unit, installation and commissioning are included as well; the small models delivered flat-packed can be assembled by our team for a 390 € surcharge.
What exactly makes up the price is covered in the article on the price of an outdoor sauna. Heating costs for your model and your energy prices are calculated by the running-costs calculator, and winter use is covered by the guide to a sauna in winter.
Type, size, timber, stove, glazing and benches come together in the configurator and you see the price at once. If you are also considering the water side, the comparison of a sauna and a hot tub says which is worth buying first; hot tubs are in the hot tubs category.
What happens in the body during a sauna session and after it. Every figure on the cards comes from a published study — the source list is below the cards.
Heat dilates the peripheral vessels and the body redirects blood to the skin: instead of 5 to 10 %, it takes 50 to 70 % of the flow. Cardiac output rises by 60 to 70 %, almost entirely through a faster pulse — 120 to 150 beats per minute.
After hard training the effect shows up mainly in mobility: in a controlled trial the sauna group had 15 to 26 degrees more passive range of motion on day two than the control group. Faster lactate clearance is not confirmed by the studies.
Two rounds at 90 °C draw 0.3 to 0.5 kg of sweat — which is why you drink before and after. Regular sauna use is associated with a more stable skin barrier, higher stratum corneum hydration and faster recovery of skin pH.
Induced hyperthermia triggers the synthesis of heat shock proteins: serum HSP70 rose by 144 % in trained and by 271 % in untrained men after a first sauna bath. White blood cell counts rose by 7 to 14 % in a further study.
The best documented effect of heat on sleep is the drop in core temperature after cooling — it shortens sleep onset if you leave one to two hours between the sauna and bed. Deeper sleep stages have never been measured after a Finnish sauna; 83.5 % of sauna users in a global survey do report better sleep.
During cool-down, heart rate variability shifts towards parasympathetic dominance: the low-frequency band falls and the high-frequency band rises. Resting pulse at the end of recovery was 68 beats per minute against 77 before the sauna.
The figures are group averages from the protocols of the studies listed (most often 30 minutes at 73 °C or 15 minutes at 90 – 96 °C), not a promise for an individual. Sauna bathing is not a treatment. With unstable heart disease, an acute infection, during pregnancy or after alcohol, talk to your doctor first.
Six areas that decide how the sauna will be used and what its running costs will be.
The solid timber of a sauna is not just cladding. It forms a heat-accumulating mass that evens out humidity peaks without condensation in the core of the wall.
The shape of the structure decides everything else — how much space the sauna takes, how fast it heats up and what fits into it besides the cabin. We carry six types.
The difference is not only visual. A cylindrical shape holds the least air per bather, so it heats up soonest.
| Type | What defines it | Capacity | Price from |
|---|---|---|---|
| Barrel | cylindrical shape, smallest footprint, fast warm-up | 4–6 people | €4,825 |
| Cube | straight walls, fully usable interior | 4–8 people | €4,653 |
| Igloo | arched structure with an entrance hall | 4–8 people | €6,577 |
| Modular | cabin with a shower zone in one unit | 6 people | €7,729 |
| Cabin | entrance hall or covered terrace | 6–8 people | €7,469 |
| Panoramic | glazed front wall with a view of the garden | 6–8 people | €7,819 |
Capacity is not only about the footprint, but also about the number and layout of the benches.
What surrounds the cabin decides whether the sauna stays usable in frost.
The choice of timber affects thermal capacity, hygiene and how the sauna survives years outdoors. We select structures made of kiln-dried solid timber so the profiles do not move after installation.
Two base versions. The difference is not only the colour — thermowood is timber treated with high heat and no chemicals.
| Version | Shade | Dimensional stability | When to choose it |
|---|---|---|---|
| Nordic spruce | light, natural | good | Base price, light interior, faint scent of resin |
| Thermowood | darker, warmer | higher | Year-round outdoor use, maintenance-free shell |
The inside of a sauna is always left unvarnished — high temperatures do not tolerate it. The surfaces you touch therefore use timber with low thermal conductivity.
The shell can be painted in eleven shades at no extra cost, or left unpainted.
The stove is the only part of a sauna that wears out over time. That is why we supply branded Harvia stoves, for which service and spare parts are available.
This decision affects site preparation, running costs and how the sauna is switched on.
| Electric stove | Wood-burning stove | |
|---|---|---|
| Output | 8 or 9 kW | up to 22 kW |
| Site preparation | 400 V supply with its own breaker | chimney and clearance from combustibles |
| Warm-up | 45 – 60 minutes | 40 – 70 minutes |
| Operation | switch on and wait, even remotely | stoking during the session |
| Löyly | milder | stronger |
| Suits | regular use, a city garden | a cottage, the atmosphere of fire, a site with no supply |
We work with Harvia. The choice of stove is among the decisions that are most expensive to change later.
| Model | Type | What defines it |
|---|---|---|
| Harvia Top Steel 9 kW | electric | A basic, reliable solution for ordinary cabins. |
| Harvia Cilindro 9 kW | electric | More stones and gentler heat. |
| Harvia Legend WiFi | electric | Switch on from your phone, timer and temperature control. |
| Harvia M3 | wood-burning | For small and medium cabins. |
| Harvia Pro BlmSchV | wood-burning | Meets the German emission limit — for locations with stricter rules. |
| Harvia Legend 240 | wood-burning | For the demanding, with ample room for stones. |
If you want to walk into an already hot sauna, remote control is the greatest convenience you can buy.
A chimney is part of the safety design, not an accessory. The type depends on where it runs and how the sauna is installed.
In terms of heat loss, glass is the weakest point of any sauna. That is why toughened safety glass is used and the lower edge of the glazing stays above bench level.
Doors are 6 mm toughened glass, front and panoramic glazing 8 mm. Both withstand thermal shock.
| Element | Thickness | Variants |
|---|---|---|
| Door | 6 mm | clear toughened glass or toughened black glass |
| Front glazing | 8 mm | toughened, tinted or black |
| Panoramic wall | 8 mm | glazed front wall on panoramic models |
The size and position of the glazing decides whether you look out at the garden or at the neighbours.
With year-round use, insulation pays for itself in consumption after the first season.
| Layer | Specification |
|---|---|
| Wall thickness | 42 to 200 mm depending on model |
| Roof and floor | 100 mm mineral wool |
| Outer shell | on 12 mm OSB board |
| Interior lining | Tatra profile |
| Roofing | asphalt shingle, torch-on bitumen, wooden shingle or sheet metal |
The bench layout determines how many people the sauna actually serves and whether you can lie down in it. After installation this no longer changes.
Depending on the model, benches come single-tier or two-tier.
A sauna is most often used after dark, so light is not a detail.
Small things that are hard to add once the sauna is installed.
The most common cause of dissatisfaction is not a weak stove but poor ventilation. Without air exchange a sauna feels stifling even at the right temperature.
The aim is regular air exchange without a draught in the seating area.
Outdoor saunas use a gravity system: intake beneath the stove body and extraction in the opposite corner below the benches. Warm air then passes through the whole cabin instead of sitting under the ceiling. For installation inside a house, the sauna is connected to heat recovery through closable dampers.
This is the item most often left to the last minute — and it delays handover.
We deliver the sauna assembled, so access to the installation point matters as much as the base.
The base must be level and load-bearing — a compacted surface, paving or concrete footings are enough; a foundation slab is not required. We need to know the width of the access route and whether the site can be reached by crane or high-lift truck. For a sauna on a terrace, the load capacity of the structure also has to be checked.
What follows once the configuration is approved.
