That's an excellent question! Yes, you absolutely can, and in fact, rectangular or square-shaped outdoor trash cans are specifically designed for this purpose. Unlike round bins that protrude, their flat back panels sit flush against walls, fences, or in corners, making them a fantastic space-saving solution for patios, decks, side yards, or narrow passages.
When shopping for one, look for bins described as "rectangular," "square," or "wall-hugging." Materials matter too: durable resin is common and weather-resistant, while stainless steel offers a sleek, modern look. Consider features like a tight-fitting lid to deter pests, wheels for easier movement (though some wall models are stationary), and a capacity that suits your household's needs.
The key benefit is maximizing your usable floor space. By tucking the bin neatly against a wall, you keep your outdoor area looking tidy and open. So, not only can you get one, but it's also a highly practical choice for organized outdoor waste management.
