Great question — and one we hear from nearly every customer before they place an order. The short answer is: yes, our factory offers drainage liners as an integrated option on most of our planter boxes, but they are not automatically included in the base price of every model. Whether you need to purchase the liner separately depends entirely on which planter series you choose and how you plan to use it.

Let me explain in more detail so you can make the right decision for your project.

First, understand what a drainage liner actually does. A drainage liner is a protective layer — usually made from perforated plastic, geotextile fabric, or a rigid mesh — that sits inside the planter box between the soil and the structure itself. It serves three main purposes: it allows excess water to escape freely, it prevents soil from clogging the drainage holes, and it protects the interior surface of the planter from constant moisture and root abrasion. Without a proper liner, even a well-built planter box can suffer from water pooling, root rot, and premature material degradation.

At our factory, we build planter boxes from a variety of materials: cedar, redwood, galvanized steel, fiberglass, and recycled composite. For the metal and fiberglass models, we offer a pre-installed drainage liner system as a factory upgrade. This means the liner is bonded to the interior walls and bottom before the box is finished, so you don’t have to fuss with cutting or fitting anything yourself. For our wooden planter boxes, we strongly recommend adding a separate liner kit, because wood naturally absorbs moisture and benefits the most from an extra barrier. However, we do not pre-install liners in wooden boxes by default — not because we want to sell you more parts, but because different plants require different drainage levels, and some customers prefer to install a custom liner after they receive the box.

So, to directly answer your question: yes, our factory offers drainage liners, but only certain models come with them included. If you are ordering a fiberglass or galvanized steel planter box from our "Pro-Drain" line, the liner is already built in — you do not need to buy it separately. If you are ordering a wooden planter box or a basic metal box from our "Classic" line, the liner is not included, and you will need to purchase a separate drainage liner kit from us or from any garden supply store. That kit costs about 15 to 30 percent of the planter’s price, depending on size and material.

However, we do offer a very convenient option: when you place your order on our website, you can add a compatible drainage liner kit directly to your cart. The system automatically matches the liner to the exact dimensions of the planter box you selected, so there is zero guesswork. Many customers choose this route because it guarantees a perfect fit and saves them a trip to the hardware store. We also provide free installation instructions with every liner kit, including diagrams for proper placement of the drainage holes and how to angle the base for optimal water flow.

One more thing to consider: if you are using your planter box outdoors, we recommend adding a drainage liner regardless of whether your planter already has built-in drainage holes. Why? Because in heavy rain, a liner helps to channel water away from the sides of the box, preventing soil from becoming waterlogged and reducing the risk of your planter cracking in freezing temperatures. If you are using the planter indoors, a liner is even more critical — it protects your floors and furniture from moisture damage, and it makes the planter much easier to clean and move.

In short, our factory does offer drainage liners, and whether you need to buy them separately depends on the model you choose. The best approach is to check the product page for the specific planter box you are interested in. Look for the words "Drainage liner included" in the specifications. If you don't see that phrase, simply add the matching liner kit during checkout — it will arrive in the same shipment, ready to install in minutes. If you have any further questions about your specific planter size or material, feel free to contact our support team; we're happy to recommend the right drainage solution for your plants and your climate.
