⚠️ Installation Requirements

Important! A proper foundation is essential to maintain the structural integrity and warranty of your sauna. Therefore, we highly recommend following our foundation drawings and consulting a qualified local builder or engineer.

If the base is not properly constructed, it may lead to structural deformation, window/door misalignment, or in extreme cases, collapse. Make sure the base is level, rigid, and waterproof. Ultimately, we advise a concrete foundation with appropriate drainage and water-sealing before installation.

Failure to follow base recommendations will void your warranty.
