Garden saunas are no longer a luxury reserved for exclusive spa resorts – in 2026, they are one of the most frequently chosen investments for Polish gardens and recreational plots. If you're wondering how much a garden sauna actually costs, what influences the price, and what the installation looks like – this guide answers these questions with specific figures.
How much does a garden sauna cost in 2026?
Prices for good quality garden saunas start from approx. PLN 11,990 for a compact model for 2-3 people, with a Harvia electric heater and full thermal insulation. Prices increase with size, finishing material, and additional features – larger barrel or cubic saunas for 6-8 people are in a higher price range. It's worth remembering: saunas significantly cheaper than this threshold are rarely of Finnish production and usually have thinner insulation, which later translates into higher electricity bills and a shorter lifespan for the structure.
What influences the price of a garden sauna?
Size and capacity
The primary price-forming factor is the size. A sauna for 2 people uses less wood, less insulation, and requires a less powerful heater than a barrel structure for 8 people, designed for social gatherings. If you are buying a sauna for a couple or a small family, there's no point in overpaying for capacity you won't use.
Heater type – Harvia electric or wood-fired
Harvia electric heaters – one of the most recognizable brands on the sauna heater market – offer a predictable price related to power (in kW), matched to the cabin's volume. Wood-fired heaters eliminate the cost of electrical installation but require a chimney and chimney liner, which often negates the savings.
Material – spruce or thermowood
Standard Scandinavian spruce cladding is cheaper than thermowood – wood subjected to thermal treatment, more expensive to produce, but much better at withstanding Polish weather conditions: moisture, frost, and UV radiation, without graying or cracking.
Garden sauna installation – what does it look like?
Each sauna is produced to order, so production time is usually 4-6 weeks from specification confirmation. Delivery takes place directly to the specified address, and a leveled, stable foundation is needed on site – usually, paving stones, a concrete slab, or a wooden terrace are sufficient. For electric models, appropriate power supply is required – we advise on this matter already at the ordering stage.
Harvia heaters – why they are a standard in premium saunas
Harvia heaters are the choice of most premium sauna manufacturers worldwide – valued for even heat distribution, durability, and stable thermostat operation. In our electric saunas, the Harvia heater is individually selected for the cabin's volume, so that a temperature of 80-90°C is usually reached in 30-45 minutes, regardless of the season.
Outdoor saunas vs. indoor saunas – differences
An outdoor sauna, unlike a cabin built into a bathroom or basement, is a self-contained, fully insulated structure, delivered ready for quick assembly. Such a garden sauna operates independently of the house's installations, does not require interference with existing rooms, and can become a separate, year-round relaxation zone in the garden. Additionally, a sauna placed in the garden does not generate moisture inside the house, which can be a problem with saunas installed in the bathroom or basement.
Financing – installment purchase
A garden sauna is a significant investment, but you don't have to pay the entire amount at once. We offer installment purchases through Przelewy24 and PayPo, allowing the cost to be spread over time, adapting it to the production and delivery schedule.
Guarantee and quality of Finnish production
Every sauna in our offer is Finnish production – from a country with the longest tradition of sauna building in the world – with a full manufacturer's warranty covering both the structure and the heater. This is a guarantee that genuinely protects the investment, not just on paper.
