Full Panoramic Window Kit

Thermory barrel sauna with Full Panoramic Window Kit — all-glass back wall

Transform the rear wall of your sauna into a panoramic vista. The Full Panoramic Window Kit replaces the standard rear panel with a full-height tempered glass window — pulling sunlight in and opening up your view to lake, forest, or backyard. Built from the same thermally-modified Spruce framing as the sauna body, sealed for sauna humidity, and engineered to handle daily heat cycles for decades.

Juniper Half Wall Panel Kit

Thermory Juniper Half Wall Panel Kit installed in a barrel sauna

Add a contrasting feature wall in genuine Finnish juniper — a dense, aromatic hardwood that resists moisture and releases a subtle scent in the heat. The half-wall panel adds visual depth at the seating area while keeping the upper sauna open and bright. A signature Nordic accent.

Why Thermory

Thermory is the only thermally-modified barrel sauna manufacturer in North America. We heat and steam our Nordic spruce to chemically alter the wood at the cellular level — releasing sugars that attract rot, stabilizing the cell walls against moisture, and locking in dimensional stability that cedar can't match. Result: a sauna that doesn't shrink or warp through changing seasons and outperforms competitors on durability, rot-resistance, and clean aesthetic. No chemicals. No sealers required. Just wood, perfected.
