Project Specifications & Guidance

Foundation & Weight
Level Support

The sauna weighs approx. 300-400 lbs empty. Needs a flat, level surface. For indoor use, tile, concrete, or vinyl flooring is fine. For outdoor cabin saunas, build a concrete or gravel pad.

Electrical Requirement
220V Dedicated

Requires a dedicated 220V-240V, 30-40 Amp double-pole GFCI breaker. Must be hardwired by a certified electrician using outdoor-rated conduit.

Backyard Spacing
Clearances

Sauna dimensions are 70.8"L x 47.28"W x 74.86"H. Allow at least 2 feet of clearance around all sides for barrel bands adjustment and airflow. Make sure there are no low-hanging trees above.

Timber Maintenance
Sealing & Care

Apply a high-quality UV-inhibiting, water-repellent sealant to the outer wood surfaces immediately after assembly. Never apply stain or sealer to the inside walls or benches.
