Yes, our planter box factory can include both drainage holes and liners, depending on the model and the level of patio protection your clients need. For standard outdoor planters, we can pre-drill drainage holes, add knockouts, or build in a liner-ready interior. For projects where staining is a major concern, we recommend a removable liner with a sealed base, a drainage layer, and an overflow channel or drip tray. This allows excess water to move away from the soil while keeping the patio surface clean.

We also offer raised feet, hidden saucers, and custom overflow fittings so planters can drain well without water running directly onto paving. Liners can be removable for cleaning and can be specified in materials suited to the project. If your clients want the look of a built-in planter with patio-safe performance, our factory can customize hole placement, liner depth, and drainage accessories. Share your planter dimensions and intended use, and we can confirm the best drainage-and-liner configuration.
