Onyx Zenith | Panoramic Outdoor Barrel Sauna

A four-person outdoor barrel sauna in Nordic spruce with a panoramic front glass facade. Modern panoramic design vs. traditional barrel profile, 8mm tempered safety glass, traditional rock heater with lava stones. The premium panoramic barrel for backyards where the cabin needs to read as architecture.

Key Features

• Panoramic glass facade: Wider-than-typical front glass area — the barrel reads as more architectural and lets more natural light in for daytime sessions.
• Premium Nordic spruce staves: Kiln-dried staves bound with corrosion-resistant steel bands.
• Traditional rock heater with lava rocks: Authentic Finnish heat source with included basalt and lava-rock stones.
• Spacious 4-person seating: Facing slatted-spruce benches sized comfortably for four adults along the barrel curve.
• 8mm toughened tempered safety glass: Premium glass spec — both safety and visual openness.
• Outdoor-rated steel hardware: Corrosion-resistant bands and cradle stands for all-climate durability.
• Weather-treated exterior: Kiln-dried spruce with weather treatment for four-season outdoor use.

Why You'll Love It

The Onyx Zenith is the panoramic-glass barrel — built for backyards where the cabin needs to read as deliberate architecture rather than rustic-cottage. The wider front glass area is the differentiator: standard barrels have small glass doors that read closed-off from the yard; the Onyx Zenith's wider facade keeps the cabin visually open.

For households with a contemporary backyard, modern house, or thoughtful landscaping, the Onyx Zenith fits the design language. The 4-person interior is sized for the typical use pattern (couples plus a guest, household plus a friend), and the traditional rock heater with included stones means the cabin's ready to use day one — no separate heater purchase, no integration risk.
