Thermory 2 Person Barrel Sauna No 55 DIY Kit

Full Panoramic Window Kit

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

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.

Add-on Modifiers

Stack any add-on with your chosen Configuration and Heater bundle — picked separately so you only pay for what you want.

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.
