Foundations

Foundations for an outdoor sauna in a cold climate

Match the foundation to your soil, slope and frost depth so the sauna stays level through freeze-thaw and frost heave.

Clay heaves and rock stops screws — the right foundation and drainage for difficult soil.

A level base keeps doors closing, water draining right and the structure sound — here's how.

Lighter, exposed saunas can catch the wind — anchoring to a solid foundation keeps them put.

Levelling, drainage above and below, and the foundations that suit a hillside build.

Yes — a stable, level, drained base. How the cradles concentrate load, and which base to pick.

Footings poured below the frost line — the proven, adaptable base for framed saunas.

Quick and cheap for a light sauna — but they sit on the surface, so frost is the catch.

Tempting and tidy for a light sauna — but only if the base beneath the pavers is right.
