Manufacturing & installation by hand
Timber of French origin is worked with care to guarantee an elegant, lasting finish. The bespoke frames are assembled and insulated before the Swedish stove and the volcanic stones are fitted.

Finishing touches & commissioning
The accessories — bucket, towels and aromatic spray — complete the installation. After a full test of the electrical system and the stove, your sauna is ready to use, at home, in complete safety.
Fine materials for lasting comfort
We select only European materials recognised for their quality and their durability.
Solid timber of French origin offers unmatched insulation and natural beauty, while the Harvia Swedish stoves, from the birthplace of the traditional sauna, deliver even heat and complete reliability.
Every detail, from the volcanic stones to the lighting, works towards a calm and authentic atmosphere.

FAQ
Dreaming of a wellbeing space built into your home?
Entrust the design of your indoor sauna to our craftsmen in Haute-Savoie and enjoy a unique, lasting and calming experience.
What is the difference between an infrared sauna and a traditional sauna?
A traditional sauna heats the surrounding air with a stove and volcanic stones, creating a dry heat that can reach 80 to 100 °C. It encourages deep sweating and profound muscle relaxation.
An infrared sauna heats the body directly using infrared panels. The temperature is gentler (50 to 60 °C) but the heat penetrates deeper into the tissue, which makes it ideal for daily use.
Which wood is best for an indoor sauna?
The choice of wood is decisive for the comfort, the durability and the look of your sauna. The best-suited species are:
- Aspen: pale, resin-free and pleasant to the touch, perfect for contemporary interiors.
- Red cedar: prized for its natural scent and its resistance to moisture.
- Spruce: traditional and warm, ideal for a Nordic feel.
At Zen Sauna we use solid timber of French origin exclusively, dried and treated to withstand heat for years.
How long does it take to install a bespoke sauna?
Installing a bespoke Zen sauna depends on the dimensions, the type of model (indoor or outdoor) and the finishes chosen. On average, allow:
- 1 to 2 days for construction on site,
- then 1 day for full installation by our team.
Once the electrical commissioning and the stove tests are done, your sauna is ready to use straight away.
Can a sauna be installed in a flat?
Yes, provided the room is well ventilated and has a suitable electrical supply. Our bespoke indoor saunas fit easily into a bathroom, a dressing room or a dedicated space.
We carry out a tailored technical study to guarantee that your project is both feasible and safe, with no compromise on comfort.
How do I look after an indoor sauna?
Looking after a sauna is simple, but essential if it is to keep its looks and its lifespan.
- Air the sauna after every use.
- Wipe the benches and walls with a damp cloth and a mild, non-abrasive product.
- Avoid standing water and check the seals regularly.
- Every six months, sand the wood lightly to refresh the surface.
The materials we use — solid French timber and Nordic equipment — make this upkeep easy while guaranteeing exceptional durability.
