That's a common challenge in city living! Finding a trash can that fits a narrow sidewalk is all about maximizing limited space. First, I'd recommend checking with your local municipal sanitation department. Many cities have specific programs or approved vendors for public space fixtures, and they often offer compact models designed precisely for tight spots like narrow walkways.
If you need to purchase one independently, look for "compact" or "slim-profile" public litter bins. Retailers specializing in commercial or municipal supplies are your best bet. Key features to prioritize include a vertical, slender design (often called a "tower" or "column" bin) and a small footprint. Materials like coated steel or aluminum are durable for outdoor use. Consider a model with a top-opening lid rather than a front door to save horizontal space. Anchoring it properly is crucial for safety on public sidewalks. A well-chosen, small-scale bin keeps the area tidy without obstructing pedestrian flow, making your narrow sidewalk both functional and clean.
