For safety, stability, and long-term performance, all saunas must be installed on a solid, level surface.

A firm base ensures the structure remains stable and that doors, panels, and fittings operate correctly over time. Common suitable surfaces include:

• Concrete pads or slabs

• Patios or paving stones

• Decking with adequate structural support

We don’t recommend installing a sauna directly on grass, soil, or uneven ground, as this can lead to movement, water ingress, or structural issues over time.

If you’re unsure whether your chosen location is suitable, our team will be happy to advise on base preparation before installation, ensuring your sauna is set up securely and built to last.
