When building an outdoor sauna, it's worth starting by exploring different outdoor sauna options. If you like the style of the Ehta collection and are looking for a more affordable option than market prices, we would like to help you build your sauna.
Outbuilding building permit
Once the idea of a future sauna has taken shape, it is a good idea to find out how much building entitlement you have left on your plot. You can get help from the local building authorities. Building control will also clarify any potential conditions for the future sauna: what kind of colouring, surface material, and roof the sauna can have. In addition, building control will provide guidance on the necessary permits and named responsible persons.
Generally, an outdoor sauna requires a building permit. The architectural drawings of the model sauna (elevation, floor, and foundation plans) are included in the price and can be used when applying for a building permit. In some municipalities, building control requires more detailed permit drawings.
We will assist with the building permit process as needed.
Built-in sauna foundations
The choice of foundation is determined by the type of soil on which the sauna is to be built. What is the soil's load-bearing capacity and frost susceptibility. A pillar foundation is a good option for very load-bearing ground or rock. A screw pile foundation is well-suited for clay and sandy soil. It is advisable to build the sauna's foundations well, and it is recommended to use industry professionals for the implementation of the foundations.
The image shows a sauna (Sauna 24) that has been erected on pillar foundations. In this case, constructing the foundation was effortless and inexpensive. The bedrock was flat and at ground level. A few holes were drilled into the bedrock per pillar, after which Lammin Betoni's pillar blocks were stacked, reinforced (partially into the bedrock holes), and mortared.
Wastewater
When using an outdoor sauna with fetched water, the amount of wastewater is small and can be connected to the municipal sewer network, absorbed into the ground using an absorption pit, or the water can be directed into a stone pit constructed from coarse gravel, from which the water will seep into the soil. Building control typically provides guidance on wastewater treatment.
