Absolutely—our planter box factory specializes in custom dimensions, including the shallow profiles required for window sill installation. Whether you are working with a narrow interior sill or a tight exterior ledge, we can engineer boxes as shallow as 2 inches deep while maintaining structural integrity and proper drainage.

Many standard planter boxes are built for depth, but we understand that window sills demand a different approach. Our design team evaluates your specific sill width, overhang, and weight capacity to craft a box that sits flush, stable, and visually balanced. We use rot-resistant materials such as cedar, aluminum, or recycled composite, with optional pre-drilled mounting holes for secure attachment.

For shallow planters, drainage is critical. We integrate precision-drilled holes at the lowest point without compromising the box’s slim aesthetic. You can also choose from a variety of finishes: natural wood grain, powder-coated metal, or UV-resistant plastic. If your sill receives direct sunlight, we recommend adding a reflective liner to protect roots.

We have produced shallow boxes for kitchens, bathrooms, and apartment windows—each measured, fabricated, and tested to hold succulents, herbs, or flowers without tipping. Simply provide your sill dimensions, and we will adjust the planter depth accordingly. No minimum order quantity is required for custom sizes.
