A classic timber sauna blends seamlessly with nature.
The Hannu sauna is a modern classic that is available in 44, 70 or 90 mm wood thickness. The sauna room is also slightly larger than our previous models for added comfort. The glass section lets in superb natural light and brings nature closer. The 4.2 x 2.5 m sauna includes a handy porch where you can hang your clothing and store the wood for the stove. Tailor-made aspen benches add a beautiful finishing touch.
Our popular log cabins are easy to assemble with the help of our easy to follow manuals. If any questions arise during assembly, feel free to call our customer service and talk to one of our building experts. We also offer installation packages if you do not want to construct the sauna yourself. Our skilled and experienced Polhus contractors will visit your home and do all the work for you.
You can also select from our accessory packages to complete the sauna. We offer both Electric and Wood sauna heaters and various options for roofing, drainage and solar cells.
The Hannu is a cosy sauna where you’ll have many enjoyable and relaxing sessions!

How to assemble a sauna cabin
What do previous customers think about our sauna cabins?*
*The survey was conducted in 2020 and a total of 98 customers took part, out of 299 who were askedWhat did you like about the garden house?
"Great customer service over the phone. The delivery was on time. All the materials were included and were packed well..”
"It was a complete set. Good amount of screws, no skimping on quality in any way.”
"You could feel the quality. Good windows and doors. Well packed and sorted.”
What could be improved?
"I received good customer support with what's needed for the foundation, treatment of the shed and ventilation but an (even) clearer FAQ on the website would have made it easier.”
"The description of how to mount the wood burning stove with chimney and water tank”
”Smaller details should be in the kit itself - in the window and door descriptions you have to figure things out a bit by yourself”
