Install Liner and Wooden Panels
At 17:20 in
I Built A Cold Plunge With Filtration That ACTUALLY WORKS
What happens here
A plastic liner is placed inside the poly tank. The excess liner material is folded over the top edge of the wooden frame and temporarily secured with screws until the top trim is added. Exterior wooden panels are cut to size and stained. The builder mixes Amber-colored Minwax stain with darker Minwax stain to achieve a desired natural, warm tone. The exterior of the wooden frame is then stained with this custom mix. After the stain dries, two coats of oil-based urethane are applied for UV protection, mold/mildew resistance, and overall durability against outdoor elements. The builder also creates a basic pressure-treated 2x4 frame to elevate the cold plunge slightly off the ground, ensuring proper drainage and preventing moisture issues.
Goal: A plastic liner is installed inside the tank, and wooden panels are cut and stained to cover the exterior of the frame, giving it a finished, barrel-like appearance.
