That's an excellent question that many people have when purchasing outdoor trash cans! Generally speaking, most standard outdoor trash cans do not come with liners included in the package. You'll typically need to purchase trash bags or liners separately to fit your specific can.
Some premium or specialized models might include a starter set of liners, but this is relatively uncommon. The reason manufacturers usually don't include liners is that outdoor trash cans come in various sizes and shapes, and people have different preferences for liner thickness and material.
When selecting liners for your outdoor trash can, consider these factors: measure your can's dimensions carefully, choose durable materials that can withstand outdoor conditions, and select appropriate thickness based on what you'll be disposing. Many homeowners find that heavy-duty contractor bags work well for larger outdoor bins, while standard kitchen bags might suffice for smaller patio cans.
Remember that using proper liners will help protect your trash can from stains and make cleanup much easier. They also help prevent liquids from accumulating at the bottom of your can. You can find compatible liners at most home improvement stores, online retailers, or sometimes directly from your trash can manufacturer.
It's always a good idea to check the product description or contact the manufacturer if you're unsure about liner compatibility before making your purchase.
