Almost Heaven Olympus 6-Person Cabin Sauna

The Almost Heaven Olympus stands out as a serious indoor traditional sauna designed for high-capacity use. Constructed using solid 1-1/2-inch Nordic spruce planks with a tongue-and-groove design, the walls and ceiling panels fit together securely without needing complex framing. The timber thickness provides steady heat retention inside your home, while the full glass front wall and matching side windows keep the large interior feeling open rather than enclosed. Aspen wood is used for the comfortable multi-level benches and door handle, remaining cool to the touch and resistant to splintering.

At the heart of the setup is a powerful 9kW Harvia Virta electric heater paired with the Xenio digital control panel, which manages temperatures up to 180ºF efficiently within an hour. Because of the high 9kW draw, you will need to arrange for professional 220V, 40-amp hardwire installation using 8/3 wire. The sauna uses your existing indoor finished floor as its base, simplifying the physical footprint requirements.

Assembly takes roughly 6 hours for two people using a standard cordless drill, relying on pre-cut panel sections and stainless steel hardware. Maintenance is straightforward, requiring only basic wipe-downs of the aspen benches and spruce interior after heavy steam sessions. Backed by a limited lifetime warranty on the room itself, it offers a robust long-term option for large households wanting a true indoor steam experience.
