Revive Plunge 4-Person Traditional Sauna with Extension Kit

The 4-Person Traditional Sauna with Extension Kit gives you more than a sauna — it gives you a complete outdoor wellness setup. The covered deck extension integrates seamlessly with the sauna structure, extending your outdoor footprint with a dedicated covered area for a cold plunge tub, seating, or recovery equipment. Built from the same thermo-treated hemlock with natural oil finish, it creates a cohesive, professional-looking outdoor space that feels purpose-built rather than pieced together.

The sauna itself is built from thermo-treated hemlock finished with natural tung oil and features a two-tiered L-bench design that comfortably seats up to 4 people — with a removable right-side bench for those who prefer more open floor space. The 8kW Harvia heater delivers powerful heat to 194°F in as little as 15 minutes with real steam from the included stones, bucket, and ladle. A touchscreen WiFi control panel lets you pre-heat before you arrive, and color-changing LED lighting, reclined backrests, built-in ventilation, and Bluetooth speakers complete a premium interior. Pre-assembled panels and an included roofing kit support both indoor and outdoor installation. Requires a dedicated 240V / 50A circuit — a licensed electrician is required for electrical connection.
