Almost Heaven Worthington 5-Person Cabin Sauna

Constructed from solid 1-1/2-inch thick Nordic spruce panels, this indoor cabin utilizes tongue-and-groove joinery to provide stable structure and natural thermal insulation. The thick wood sections help retain heat effectively while maintaining a traditional aesthetic. The front wall features a large pane of tempered and tinted glass alongside a glass door, which prevents the 80-inch tall interior from feeling cramped while you are inside.

At 8kW, the included heater requires a hard-wired 240V, 40-amp electrical service, meaning you will need to hire a licensed electrician for proper installation. The interior lighting runs on a standard 110V plug-in connection. The kit ships in pre-assembled wall, roof, and bench sections, allowing two people to put the unit together in roughly six hours using just a cordless drill and basic tools.

Inside, the multi-level seating arrangement includes a 77-inch upper bench with an L-extension and a separate lower bench, giving users options for different heat zones. Because the unit does not include a finished floor, you must install it over an existing hard surface such as concrete, tile, or laminate. Overall, it is a well-built indoor traditional unit tailored for basement or spare room installations.
