PVC 2 in 1 Window Box or Liner

PVC 2-in-1 Window Box / Planter Liner

Protect your wood window boxes and planters — or skip the box altogether — with our PVC 2-in-1 Window Box Liner, made from rot-proof, mildew-resistant, insect-proof cellular PVC. Designed for long-term outdoor use, this durable liner helps prevent soil and water from damaging traditional planters while offering a clean, modern look that also works beautifully as a standalone planter or window box.

These liners are sized to fit seamlessly inside our metal window box assortments, making them the perfect upgrade for keeping your window boxes clean, protected, and long-lasting.

Built with ½" thick cellular PVC, they’re lightweight yet extremely resilient, holding up season after season in any climate — including freezing winter conditions. Each box includes pre-drilled drainage holes for healthy plants and easy planting.
