4x8x7 Custom Indoor Cedar Sauna Kit

Fits 4–5 people

The 4×8×7 indoor cedar sauna kit is a wider layout that gives you more bench space and a more open sauna feel while still keeping an efficient 4-ft depth. It works especially well in larger basements, dedicated home wellness rooms, and shared family sauna setups.

With a 4-ft depth and 8-ft width, this size is ideal for 4–5 people, while maintaining efficient heat circulation and quick warm-up times when paired with a properly sized electric heater.

Constructed from Canadian Western Red Cedar, this sauna kit provides long-term durability and a comfortable seating surface. Clear or knotty cedar options are available based on your design preference and budget. Standard 7-ft height, with an optional 8-ft upgrade.

This is a liner kit designed to be installed inside a properly framed, insulated, and wired structure and may also be used inside outdoor structures such as sheds, garages, or cabins. Optional full-glass front wall (glass door included) adds a brighter, more open, high-end feel.

Kit Includes
  • Foil Vapor Barrier
  • Grade “A” cedar tongue & groove for walls and ceiling (1×4 or 1×3, 11/16″ thick — clear or knotty)
  • All tongue & groove boards finished on one side
  • Clear or knotty 2×4 Grade “A” cedar for benches and bench supports
  • Door Casings for inside and outside of the sauna
  • Corner moldings for wall and ceiling joints
  • Cedar vent grills (lower and upper)
  • Detailed sauna installation instructions

Notes & Disclaimer Framing, insulation, exterior cladding, sauna heater, and electrical work are not included. Plank Orientation (Walls + Ceiling) All of our sauna kits come standard with horizontal wall planks. Ceiling boards: The ceiling board direction is determined by the shorter interior dimension of the sauna (Depth vs. Width). The ceiling boards always run across the shortest span of the room to ensure proper support and a clean installation. Examples:
  • 10′ × 8′ sauna (D × W): shortest span is 8′, so ceiling boards run across the 8′ span (width-wise).
  • 7′ × 9′ sauna (D × W): shortest span is 7′, so ceiling boards run across the 7′ span (depth-wise).
Please confirm the ceiling-board direction for your sauna and install your ceiling joists accordingly before installation. Proper joist orientation is required to support the supplied ceiling boards correctly. If you prefer a different orientation (e.g., vertical wall planks or a different ceiling-board direction), please specify this in your order notes when placing your order (subject to price change). If no preference is noted, the default orientation will be used. Electrical Disclaimer: Bsaunas Inc. is not responsible for any electrical work. Installation must be completed by a licensed electrician in accordance with local electrical codes and the manufacturer’s installation manual. Our price builder suggests heaters based on typical kW requirements and standard clearance guidelines. It is your responsibility to ensure the selected heater is suitable for your specific sauna layout. Clearances may vary depending on heater placement (e.g., front wall vs. depth side) and wall materials (e.g., glass vs. wood). Sample images may not reflect actual clearance conditions. Always refer to the heater manual and use heat shields or non-combustible materials where required.

    The local and Wi-Fi sauna controls are essentially the same in terms of hardware and functionality. The key difference is that the Wi-Fi version includes an ID for connecting to the HUUM mobile app (Apple or Google Play). This feature allows you to remotely activate your sauna, enabling you to heat it up in advance, whether you're on your way home or just finishing a workout. It's designed to enhance convenience, ensuring your sauna is ready when you are.

    The HUUM reflector reduces the minimum required safety distances from the walls by 50%
