Shipping
Free shipping included. Indoor cabins ship flat-packed via flatbed trailer with pre-assembled panels and detailed installation instructions. Assembly typically takes two people, basic tools, and a few hours. A licensed electrician handles the heater hookup. A forklift is recommended for unloading, but the unit can also be offloaded manually piece-by-piece with three or four people in roughly 30 to 60 minutes. Indoor cabins sit on existing flooring (must be level and water-resistant: concrete, tile, vinyl, or laminate). Cabins are freestanding and can be disassembled and relocated. We notify customers two weeks before scheduled delivery.
