Our 4×5 Custom Western Red Cedar Sauna Kit is one of the most popular choices across Canada and the USA. Western Red Cedar is known for its strength, lightweight properties, and natural resistance to warping or shrinking—making it an ideal material for saunas. It also offers a cooler and more comfortable surface to sit or lean against during your sessions.

This DIY sauna liner kit provides the simplest and most cost-effective way to install a premium-quality sauna in your home or commercial space. Just add our complete kit to any pre-framed, insulated, and wired area—common installation spots include basements, backyard sheds, and wellness facilities.

Crafted from top-grade Clear or Knotty Canadian Western Red Cedar, each kit is fully customizable to suit your preferred shape and size. Sauna kits remain the most economical solution for building a sauna, and Botanical Sauna offers unbeatable factory-direct pricing.

Disclaimer:
Electrical Installation: BotanicalSauna is not liable for any electrical work. All electrical connections must be performed by a licensed electrician in compliance with local codes and the heater manufacturer’s installation guidelines.

Heater Selection: Our pricing tool provides heater suggestions based on standard kW requirements and general clearance guidelines. However, it is your responsibility to confirm that the chosen heater is appropriate for your specific sauna layout. Required clearances may vary depending on heater placement (e.g., front wall vs. side wall) and surrounding materials (e.g., glass, tile, or wood). Sample images are for reference only and may not represent actual clearance conditions. Always consult the heater’s manual and use proper heat shields or non-combustible materials when necessary.
