That's a great question! Most outdoor trash bins you buy online or in stores are not fully pre-built. They usually come flat-packed in a box, which makes them much easier and cheaper to ship. The good news is, assembly is typically very straightforward and requires minimal tools—often just your hands or a simple screwdriver.
For most models, you'll be attaching the lid to the main body and maybe securing the base or a liner. The instructions are usually clear, and many people can complete the setup in under 10 minutes. Brands design them with DIY assembly in mind, so you don't need to be a handyman.
If you want to avoid assembly altogether, look for product descriptions that specifically say "pre-assembled" or "no assembly required." However, these are less common. Your best bet is to check the "Product Details" section before buying. It will clearly state if some assembly is needed. So, while they aren't usually pre-built, putting one together is generally a quick and simple task!
