Important considerations
- Choose a heater with the right capacity: over- or under-sizing leads to inefficiency and higher costs.
- Pay attention to ventilation and insulation: well-insulated saunas consume less energy.
- Outdoor saunas require a solid foundation: take into account extra costs when placing on grass, soil or tiles.
- Permit requirement: a permit is usually not required for small outdoor saunas, but checking with the municipality is recommended.
Conclusion
The costs for a sauna range from approximately €2,000 for a compact infrared solution to €25,000 or more for a luxury custom installation. The biggest price differences are caused by the type of sauna, the choice of materials, the construction method and the desired extra options. A good preparation and clear choice in advance ensure an efficient investment and years of carefree use.
Important Choices When Purchasing a Sauna
Purchasing a sauna requires several strategic choices. The right combination of location, type, dimensions, and technical facilities largely determines the comfort, costs, and long-term use. The points below provide guidance for the orientation and decision-making process.
1. Indoor or Outdoor Sauna
Indoor placement (bathroom, basement, attic, garden house):
- Space-saving, easy to integrate into existing home
- Less exposure to weather conditions
- Better temperature protection and shorter warm-up time
Outdoor placement (garden, terrace, pool house):
- Natural environment and outdoor experience
- More spacious in terms of layout and dimensions
- More ventilation options
Consideration:
Indoors is more efficient and compact, outdoors offers more atmosphere and luxury.
2. Type of sauna
|
Type |
Properties |
Application |
|
Finnish sauna |
Hot dry air (70–100°C) |
Traditional sauna use |
|
Infrared cabin |
Deep-acting heat through radiation, lower temperature |
Fast, therapeutic use |
|
Combi-sauna |
Both Finnish and infrared possibilities |
Flexible and multifunctional |
|
Steam sauna (hammam) |
Moist heat with lower temperature |
Relaxing, suitable for skin & airways |
Consideration:
The choice depends on personal preference, frequency of use and desired
effects (intensity, relaxation, recovery).
3. Size and Seating capacity
- Available space determines the maximum size.
- Aim for at least 1 m² per person as a guideline.
- Standard configurations:
- 1-person: compact, suitable for bathroom
- 2–4 persons: most popular family size
- 5+ people: ideal for group use or outdoor placement
Consideration:
It's better to choose something more spacious for comfort, but take into account the warm-up time and
energy consumption for larger cabins.
4. Heater type and power
|
Heater type |
Characteristics |
Note |
|
Electric heater |
Most used, easily adjustable |
Requires high voltage (>3.6 kW) |
|
Wood-fired |
Authentic and suitable for outdoor saunas |
Requires a permit in some regions |
|
Combi-heater |
Dry and wet sauna settings possible |
Flexible but more expensive to purchase |
Consideration:
Ensure a heater capacity tailored to the cabin's volume (approx. 1 kW per
1.3 m³). Overcapacity leads to unnecessary consumption, undercapacity to long
warm-up time.
5. Insulation and Ventilation
- Good insulation of walls, ceiling, and floor prevents heat loss and reduces energy consumption.
- Ventilation is crucial for air exchange, safety, and condensation removal.
Consideration:
High-quality insulation materials pay for themselves in consumption costs and comfort.
6. Ease of Use
- Choice of simple manual operation, digital displays or app control.
- For infrared cabins, often integrated into the cabin wall.
- Outdoor installations require weatherproof control modules.
Consideration:
Modern operation increases ease of use, especially with frequent use.
7. Materials and finishing
- Interior cladding: often made of pine, red cedar, aspen or thermo wood
- Seats: ergonomically shaped, splinter-free, heat-resistant
- Door: transparent glass, safety glass or partially closed for privacy
- Accessories: headrests, lamps, aroma boxes, speakers
Consideration:
Choose durable types of wood and solid finishing for long-term intensive
use.
8. Connection facilities
- Electricity: power current group required from approx. 4 kW
- Water drainage (if steam generator or shower integrated)
- Ventilation duct or window opening (for natural air circulation)
- Foundation (for outdoor sauna): level, stable and frost-free
Consideration:
Have it checked in advance whether the technical facilities are present or need to be adjusted.
9. Admission and permits
- Usually permit-free in the house or garden house
- An environmental permit may be required for free-standing outdoor saunas >10 m² or >3 meters high
- Check municipal regulations regarding smoke extraction for wood-fired models
Consideration:
Always have the permit status checked before purchase or placement.
10. Budget and expansion options
|
Expansion |
Goal |
Additional cost (indication) |
|
LED lighting |
Atmosphere and visibility |
€200 – €600 |
|
Panoramic window |
View and spatial effect |
€400 – €1,500 |
|
Music or Bluetooth audio |
Relaxation |
€300 – €900 |
|
Outdoor enclosure/canopy |
Protection against rain/sun |
€1,500 – €5,000+ |
Consideration:
Not everything needs to be done immediately: plan expansions in phases if necessary.
Conclusion
Buying a sauna requires more than just choosing a model. The location, intended use, heater type, finish, and available connections together determine the technical and financial feasibility. A well-prepared decision prevents surprises and ensures years of comfortable, efficient, and safe sauna use.
