How much does a custom sauna cost in 2026
Price list by type and size, what actually drives the price, and where you can save without noticing it inside the sauna.
Price list by type and size
Each table shows the three most common sizes in standard equipment: spruce cladding, aspen benches and a standard heater. Installation is not included, delivery is (by region). Every row opens the configurator so you can adjust it.

What drives the price
1. Size
Most of the price is the area of wall and ceiling cladding, so every 10 cm of width or depth shows up in the total. Do not build bigger “just in case” – more volume means a stronger heater, longer heat-up and higher running costs. Two people fit in 150 × 150 cm, four sit comfortably in 200 × 200 cm.
2. Wood and grade
Siberian spruce is the most affordable and perfectly fine for walls. Aspen and alder cost more but stay cooler to the touch and never bleed resin. Thermowoods are darker and more dimensionally stable. Between the cheapest and the most expensive cladding there are a few hundred euros on a 2 × 2 m sauna.
Grade matters too: B – rustic has more sound knots and is the cheapest, A – standard is the usual choice and Extra is knot-free. They perform identically and differ in looks. More on the Wood for saunas page.
3. Heater
Electric heaters of 6, 8 and 9 kW differ in price less than you would expect – what matters is matching the heater to the volume. A wood-burning heater costs more and needs a chimney, but no three-phase supply. How to size it is covered in What size sauna heater do you need.
4. Equipment
A glass wall, all-glass door, LED under the benches, backrests or Wi-Fi control add tens to a few hundred euros each. Outdoor saunas add a roof, insulation, foundation and windows, which move the price more noticeably.
5. Installation and delivery
Installation is charged as a percentage of the sauna price and you select it in the configurator. Delivery costs 160 € to Slovakia, 240 € to Czechia, 380 € to Austria and 420 € to Germany; other countries are quoted individually. The configurator also shows a “Turnkey” line – the total including installation and delivery.
Three routes: best price, sweet spot, high-end
To make prices comparable we built three specifications of the same size for each type. The sweet spot is not a compromise: expensive wood goes only where you touch it.
| Best price | Grade B spruce, one aspen bench, heater sized to the volume, self-assembly. A proper sauna at the lowest price. | 6 159 € Open |
|---|---|---|
| Sweet spot | Spruce walls, but alder for the benches and the band behind them – where skin touches, the wood stays cool and resin-free. Backrest, LED and installation. | 8 356 € Open |
| High-end | Extra-grade thermo aspen with shadow gaps, three bench levels, bronze all-glass door, Wi-Fi control, backrests, headrests, lighting and forced ventilation. | 12 422 € Open |
| Best price | Classic 42 mm spruce barrel, no canopy, on your own level base. The quickest way to an outdoor sauna. | 7 767 € Open |
|---|---|---|
| Sweet spot | Thermo spruce – the stave is also the outside wall, heat treatment adds years. Canopy, pads, LED and installation. | 10 708 € Open |
| High-end | Barrel with changing room in 45 mm thermo pine, wood-burning heater with chimney, metal roof, round window, concrete base and all-glass door. | 17 447 € Open |
Where to save without losing quality
- Spruce walls with an aspen or alder band behind the benches. That contact zone up to 1.2 m costs a fraction of full premium cladding and is exactly where you feel it.
- Grade B on the walls. Sound knots do no harm; benches are always knot-free.
- Size by the number of people, not by the room. A smaller sauna heats faster and costs less to run.
- A wooden floor is optional. Tiles with a duckboard work just as well.
Where not to save
- Heater output. An undersized heater never gets the sauna hot; an oversized one cycles. Size it by volume.
- Insulation and vapour barrier on outdoor saunas. Without them the sauna will not heat in winter and the structure takes on moisture.
- Electrical work. The heater supply belongs to a qualified electrician, including the inspection certificate.
What it costs to run
An 8 kW electric heater runs about an hour and a half per session – roughly 45 minutes at full power to heat up, then holding temperature at about half. That is around 9 kWh, so about €2.25 per session at €0.25/kWh. With two sessions a week that is roughly €19 a month. An infrared cabin uses far less, a wood-burning heater no electricity at all. The configurator calculates it for your heater and your electricity price in the last step.
Frequently asked questions
Is the configurator price binding?
No, it is an estimate from our current price list. After your enquiry we verify sizes, site and details and send a binding quote within 48 hours, usually at the same level.
Why is a custom sauna more expensive than a ready-made cabin?
A ready-made cabin has fixed dimensions and equipment. A custom sauna is built to your exact space from solid wood, the heater is sized for its volume, and installation, handover and a 5-year structural warranty are included.
How long does production take?
Usually 6 to 8 weeks from order confirmation, depending on the type and season. The exact date is in the quote.
How does payment work?
A 40% deposit after the order is confirmed, the balance on delivery or after installation.
