4.5/5

Modern sauna cabin

The flagship of our sauna collection offers a sauna and a cabin in one ready-made package – everything you need for cabin life. It is designed with versatility in mind and can be equipped and modified to suit you perfectly. The large lounge area can be divided for different purposes, such as dining, sleeping, a changing room and a living room. Nature comes close when you choose large panoramic windows.

Sauna Cabin 30 is our largest model that can be built without a building permit. For a small family, it's sufficient as a main cabin for a summer cottage, or it's suitable as a first cabin for a holiday dream, to be supplemented later with other buildings. As part of a larger ensemble, Sauna Cabin 30 offers luxurious facilities for sauna bathing and ample space for accommodating guests.

Sauna Cabin 30 can be built without a permit

The Building Act was reformed at the start of 2025, and outbuildings under 30 square metres no longer require a permit. Read more from our article.

If you need a building permit, we will provide the necessary drawings and help you with the permit application. You can also order a building permit service, in which case we will apply for the permit on your behalf.

This model can be modified and equipped in many ways. We will help you design a package that suits your needs.

Sauna Cabin 30 experiences

I would have given a 10 for the excellent service, but the only minus was that the transport schedule was vague; I found out the transport time 3 days before the event, which makes it very difficult to keep one's calendar completely clear for a couple of days on such short notice. The transport and placing of the cabin, on the other hand, was a performance worth a 10. The quotation was clear and I liked the Oma Ehta pages. Communication was also just right and I got quick answers to my questions. I cannot say anything more specific about the quality of the cabin yet, as it has not been used yet.
