That's an excellent and very practical question! It's one that many homeowners, facility managers, and business owners grapple with when trying to keep their outdoor spaces clean. The short answer is: it's a mix of both. Many common outdoor trash bins do use standard-size liners, but a significant number, especially commercial and designer models, require special-order bags.
Let's break it down. You'll often find that standard, round or rectangular bins from common home improvement stores are designed to use readily available liner sizes. Think of classic 32-gallon or 55-gallon trash cans; their liners are typically a standard commodity you can find in any supermarket or online.
However, the moment you step into the realm of commercial-grade bins, designer stainless steel models, or bins with unique shapes and mechanisms (like those with swinging lids or built-in ashtrays), you often enter "special order" territory. Manufacturers of these bins usually design them to work perfectly with their own branded liners to ensure a proper fit and functionality. Using a standard bag in these can lead to tearing, slipping down into the can, or not fitting the lid properly.
So, how can you tell what you need? The most reliable method is to check the manufacturer's label inside or on the bottom of the bin. It will usually specify the compatible liner size or part number. If that's worn off, carefully measure your bin's height, width (or diameter), and depth. Don't forget to measure the lip or rim, as this is crucial for keeping the bag securely in place. With these dimensions in hand, you can compare them to standard liner charts online or contact the manufacturer directly.
In conclusion, while you might get lucky with a standard liner for a basic model, be prepared for the possibility of a special order, especially for heavy-duty or aesthetically specific bins. Investing in the correctly sized liner, even if it's a special order, saves money and frustration in the long run by preventing leaks and messes.
