12×10 U Custom Indoor Sauna Kit

The 12×10 U Custom Indoor Sauna Kit is our top-selling sauna across Canada. Built from durable, naturally beautiful Western Red Cedar, it stays strong, resists warping, and offers a cooler, more comfortable surface.

Available in Clear or Knotty Canadian Cedar, every kit can be customized to any size or layout, giving you an affordable and efficient way to build a premium sauna.
