That's a great question, and one we hear often from restaurant owners. The most popular and practical size for an outdoor trash can on a restaurant patio tends to be between 32 to 44 gallons (approximately 120 to 165 liters).
This size range strikes the perfect balance. A 32-gallon can is substantial enough to handle the waste from several tables without needing constant emptying during a busy lunch or dinner rush. It helps maintain a clean appearance, which is crucial for customer experience. The 44-gallon size is ideal for larger patios or venues with higher traffic, offering longer intervals between changes.
Why this size? Smaller bins (like 20-gallon) fill up too quickly, leading to overflow and mess. Much larger bins (like 55+ gallons) can become unsightly, difficult to move when full, and may overwhelm the patio's aesthetic. The mid-range size is manageable for staff to empty and fits well into corner stations or discreet areas.
Remember, it's often better to have two 32-gallon cans placed strategically—like near the exit and a central service area—than one oversized bin. This encourages proper use and distributes the waste load. Look for commercial-grade, weather-resistant materials like stainless steel or heavy-duty plastic with a secure lid to contain odors and deter pests.
