Sustainable Eucalyptus Construction

Every Signature 1 sauna is built with premium, sustainably sourced eucalyptus, known for durability, longevity, and natural grain. Each unit features unique variations in tone and texture.

Optimal Wood Care

Sunlighten uses high-quality wood. Minor dents, scratches, and scuffing are normal and do not affect the sauna’s integrity or operation. Variations in color or grain, and irregularities such as fine cracks, are not considered defects. During normal operation, wood may crack due to climate changes without affecting structural integrity.

Slight blemishes, scratches, or scuffs can happen in transit. Exterior blemishes can be concealed with furniture polish, oil, or other furniture treatment. Interior blemishes, scratches, or scuffs can be left alone or sanded. Avoid treatments with benzene or high alcohol concentration.
