KEISUS –
Extreme Saunas
Keisus – extreme saunas is a Finnish company building mobile saunas and small structures from Oulu. What started from a passion for sauna and craftsmanship has grown into a unique product range used across different environments.
Built to Last
Every sauna and structure is made with durability in mind. Materials and construction are chosen to handle real use, weather and movement.
Custom Built
We start from a proven base model, but most projects are tailored to match the customer’s needs, use case and visual preferences.
Construction in Northern Finland
KEISUS is best known for its mobile saunas, but its craftsmanship and know-how can also be seen in construction.
From Oulu, construction contracts and surface repairs are carried out in the Northern Finland region. The work is done according to the same principle as our own products: carefully, with functionality in mind and adherence to fit
Local professional
All work is carried out in Oulu and Northern Finland. When the work is done locally, the connection remains direct and the responsibility clear.
The same maker, the same expertise – regardless of the target.
