Foundation profile
Deck Foundation
| Principle | The sauna is carried on an existing or purpose-built raised deck structure. |
|---|---|
| Suitability | Deck-mounted cabins and pods where a strong deck can take the added load. |
| Soils | Depends on the deck's own footings; the deck must be founded for the added point loads. |
| Frost heave | Depends on the deck footings — these must reach below the frost line to be stable. |
| Drainage | Good when the sauna floor drains clear of the deck and the deck itself sheds water. |
| Build difficulty | Advanced |
A deck foundation carries a compact sauna on a strong raised deck, sharing its surface as a cooling zone. Its success hinges on verifying the deck’s load capacity and routing drainage clear of the structure.
