Walpole Outdoors Bullnose Window Box

No, you do not need a liner. This window box is designed to be planted directly into the unit, and it includes integrated drainage holes to manage water levels for your plants.

Solid cellular vinyl is an excellent choice for outdoor use because it is naturally resistant to rot, moisture, and insects. It maintains its structural integrity and appearance over time without the maintenance requirements of wood.

The window box arrives fully assembled with its handcrafted brackets, but please note that specific mounting hardware for your home's exterior—such as screws or anchors—is not included. You will need to select fasteners appropriate for your wall surface, such as brick, stucco, or wood siding.

The manufacturer automatically includes three brackets on the larger sizes of this window box to ensure proper support and stability. You do not need to choose; the design is engineered to provide the correct amount of support based on the width you select.

Yes, because the window box is constructed from solid cellular vinyl, it is easy to drill additional holes if you feel your specific plants require extra drainage.
