Turning a Wine Barrel Into a Cold Plunge Tub

Sourced a retired wine barrel from a local winery for cheap, cut it in half, and sealed the interior with a food-safe sealant made for barrels and tanks. The oak actually holds cold reasonably well on its own thanks to the wood's natural insulation.

Smaller than a stock tank or IBC tote build, so it's really a sit-in rather than a full-immersion tub, but it looks a lot nicer on a patio than the more industrial options.
