6 seats, built from thermally modified spruce
The Natural Barrel 51 seats 6 inside a 6.06 ft barrel, with 19.5 in. deep Thermo-Aspen benches and natural light through the glass door.
Thermory barrels are built from Nordic spruce modified with heat and steam only, no chemicals, so the wood resists rot and moisture and stays stable through changing weather.

Classic barrel, glass front door
The glass front door brings in daylight and keeps the barrel simple and private.

6 seats in a 6.06 ft barrel
A 6.06 ft inside diameter with 19.5 in. deep Thermo-Aspen benches. A modest footprint that still seats 6.

Heat and steam, nothing else
Thermory modifies Nordic spruce with heat and steam alone. The result resists rot and moisture and holds its shape through a Canadian winter, and it stays comfortable on bare feet.

Pre-cut, pre-milled, no cutting
Staves and cradles arrive milled to fit, so the barrel goes together with a step-by-step guide and basic tools. Inland can install it in the Okanagan, Calgary and Edmonton.
