A sauna at home is a dream for many – whether for relaxation, for health or as a high-quality upgrade to your own property. But before you decide on a model, you should know which types of saunas there are, what requirements your home must meet and what realistic costs you have to reckon with. This guide shows you clearly and concisely how to find the right sauna, what it costs and what mistakes you should definitely avoid.
How much does a home sauna cost?
The prices for home saunas vary greatly depending on the sauna type, quality, technology and installation effort. As a rough guide, simple systems cost a few thousand francs, while fully-fledged premium saunas quickly reach five-figure sums. The following price ranges will help you to calculate realistically.
Average total costs by sauna type (incl. installation)
Infrared sauna – inexpensive & energy-efficient
Costs: CHF 3,000 – 6,000
Ideal for small rooms, easy installation, very low power consumption. Perfect for people who are primarily looking for heat relaxation instead of high temperatures.
Finnish sauna – DIY, hardware store or professional
Costs hardware store / DIY: CHF 2,000 – 6,000
Costs from the carpenter / professional: CHF 6,000 – 15,000
The classic: high temperatures, traditional infusion, robust sauna climate. Professional models are more durable, efficient and better insulated.
Steam sauna / bio sauna – gentler, but technically more demanding
Costs: CHF 8,000 – 17,000
Requires stronger technology, better sealing and reliable ventilation. More pleasant temperatures, but higher installation effort.
Barrel sauna / garden sauna – ideal for outdoor use
Costs: CHF 5,000 – 12,000 (depending on wood, size & finish)
Visually attractive, heats up quickly, but often requires a permit. Plan additional expenses for foundation and electrical connection.
What really influences the price?
Sauna type
The higher the temperature and humidity (e.g. Finnish sauna or steam bath), the more demanding the stove and control technology. This significantly increases both material and energy costs. Infrared saunas are technically simpler and therefore remain in the lower price segment.
Wood quality
Premium woods such as hemlock, aspen or cedar hardly warp and withstand heat and moisture for years. They also ensure a pleasant climate, low-odour use and a longer service life. However, these advantages make them noticeably more expensive than standard woods.
Oven output & control
A powerful oven with precise control ensures even heat and shorter heating times – a noticeable gain in comfort. Modern controls with soft steam, timer or automatic climate control also increase the investment. A stronger oven is a must, especially for larger saunas, which noticeably affects the overall costs.
Insulation
A well-insulated sauna cabin retains heat longer and requires less energy – the biggest saving factor in the long term. Cheap models save on exactly this, which is why they cool down faster and consume more electricity. If you are planning a conservatory or regular use, you should definitely not save here.
Additional equipment
LED ambient lighting, glass fronts, ergonomic benches or aroma systems massively increase comfort. However, such extras quickly cost several hundred to several thousand francs. Glass surfaces in particular make construction and installation more expensive because they have to be dimensioned more strongly.
Installation effort
The more difficult the room (sloping roof, narrow cellar, little space), the higher the effort for assembly, cutting and adjustments. The high-voltage connection by the electrician is also obligatory and generates additional costs. Special custom designs or individual designs additionally increase the installation price.

Where can you install a home sauna?
A home sauna can be integrated surprisingly flexibly – space, ventilation and connections are crucial. The following locations are particularly suitable, but differ greatly in terms of comfort, costs and technical effort.
Cellar
The classic: plenty of space, stable temperatures and sufficient distance from the living area. Cellar rooms are ideal for larger saunas and usually offer good options for supply and exhaust air. Disadvantage: Often higher humidity – therefore the ventilation must be carefully planned.
Bathroom
Very comfortable, as water connection, shower and tiled floor are already available. Mini or corner saunas often fit in without any problems. Important: Check ceiling height and sufficient ventilation – space can quickly become scarce in small bathrooms.
Attic
Cosy and atmospheric, but technically demanding. Sloping roofs require custom-made cabins and good insulation so that heat does not escape. The power connection and the load-bearing capacity of the ceiling must be checked in advance.
Garden house / outdoor area
Perfect for anyone who wants to enjoy sauna as an outdoor experience. Barrel saunas or garden saunas are very popular and create a real wellness feeling. However, higher installation effort (foundation, electricity, approval possible). But maximum privacy and flexible sizes.
The different sauna types & which one suits you
Finnish sauna
The Finnish sauna is the classic for anyone who loves intense sweating and high temperatures. With 80-110 °C and low humidity, it provides a dry, powerful heat experience that strongly stimulates the cardiovascular system, immune system and metabolism. The infusion creates short-term higher humidity and temperature peaks, which enhance the sauna experience. However, a Finnish sauna requires solid insulation and sufficient space for a powerful stove. It is particularly suitable for households that are looking for a traditional sauna experience and like to do several sauna sessions with cooling phases. Because of the long heating time, it is more energy-intensive – but it offers the most authentic sauna feeling.
Advantages:
● Very intense sauna climate for maximum health effects
● Classic sauna experience with infusions
● Well suited for several people
Disadvantages:
● Higher energy consumption
● Heating time 20-40 minutes
● Requires more space & stronger power connection
Steam sauna / bio sauna
The steam sauna is much milder than the Finnish sauna and ideal for people who do not tolerate heat well. With temperatures between 45-65 °C and around 40-55% humidity, the heat feels softer and less stressful. The humid climate has a soothing effect on the skin, respiratory tract and muscles and is often perceived as more relaxing. A steam sauna requires a special steam system that must be serviced regularly, and the cabin must be well sealed. It is ideal for families, wellness lovers or households who want a gentle, circulation-friendly alternative to the classic sauna. The installation effort is somewhat higher, but it offers a luxurious wellness feeling.
Advantages:
● Gentle climate – ideal for sensitive people
● Very soothing for respiratory tract & skin
● Lower temperature load
Disadvantages:
● Humidity requires very good ventilation
● More complex technology → higher maintenance costs
● Less intense heat stimulus
Infrared sauna
The infrared sauna works differently than classic saunas: Instead of heating the air, infrared radiation penetrates directly into the skin and generates a mild warmth (35-55 °C). This means that the infrared sauna is immediately ready for use, extremely energy-efficient and ideal for short, regular wellness sessions. It is often used for muscle relaxation, pain relief and regeneration – especially popular with athletes. Since it does not generate extreme heat, it can also be installed in smaller rooms and does not require strong ventilation or a high-performance stove. However, it does not offer a classic infusion experience and sweating is milder.
Advantages:
● Very low power consumption & fast warm-up time
● Ideal for small rooms & little installation effort
● Particularly good for muscles, back & regeneration
Disadvantages:
● No traditional sauna experience
● Less sweat-intensive
● No classic infusions possible
Which wood is suitable for a sauna?
The wood is a key factor in determining the climate, comfort and longevity of your sauna. That’s why a conscious selection is particularly worthwhile. Aspen, hemlock or Swiss stone pine are particularly suitable for premium requirements. These woods are low in resin, dimensionally stable and store heat excellently without warping. They also remain pleasantly cool on the surface even with strong temperature changes – ideal for loungers and backrests.
If you have a smaller budget, you can use spruce or fir. They are cheaper, readily available and visually bright, but must be carefully dried and cleanly processed to avoid cracks or resin leakage.
Important:
● For interior surfaces & benches: Only splinter-free, low-resin premium woods (aspen, abachi, hemlock).
● For exterior walls & construction: Cheaper woods such as spruce or fir are perfectly sufficient.
● For outdoors: Weatherproof types such as cedar or thermal wood are useful.
This is how you ensure that your sauna not only looks good, but remains stable for decades.
Power consumption & operating costs (practical values instead of theory)
A typical home sauna consumes 9-14 kWh per sauna session, depending on size, insulation and stove output. With Swiss electricity prices, the costs are usually between 2.50 and 4 CHF per use – significantly cheaper than a wellness centre. Infrared saunas are even more economical: 1-3 kWh, i.e. less than 1 CHF per use. Decisive for low operating costs are good insulation and a stove whose output is exactly matched to the cabin size.
Build it yourself or have it installed?
Finished kits can be assembled yourself with craftsmanship experience – but only in simple, rectangular rooms. As soon as high-voltage electricity, sloping roofs, individual adjustments or a barrel sauna come into play, you should hire a specialist company. The professional not only guarantees safety and tightness, but also ensures that stove output, ventilation and insulation are perfectly matched. Especially with saunas, professional installation quickly pays for itself through better energy efficiency and a longer service life.
Maintenance & lifespan of a sauna
With the right care, a home sauna will last for decades. These three tips are crucial:
Clean wood gently
Sweat and skin grease settle on the benches. Therefore, clean seating surfaces regularly with mild soapy water and a soft sponge. You should avoid aggressive cleaners – they roughen the wood and shorten its lifespan.
Always use a bath towel
The towel protects the wood from moisture and prevents mildew. After the sauna, briefly wipe the benches with a damp cloth and leave the door open – this allows the cabin to dry faster and hygienically.
Small care, big profit
Once a year, you should lightly sand the seating surfaces to keep them hygienic and smooth. Also check screws, ventilation slides and seals – small maintenance prevents major damage.
A home sauna is worth it if you plan correctly
A sauna at home increases quality of life, relaxation and even health – and is surprisingly inexpensive to operate. Whether infrared, steam or Finnish: The decisive factors are suitable design, good wood, efficient insulation and professional installation. If you plan cleanly here and choose high-quality materials, you will receive a durable, energy-efficient sauna that will bring joy for decades.
