That's an excellent question, and one I've personally wondered about while struggling with a slipping liner! The good news is, yes, absolutely. Many modern urban trash bins, especially those designed for kitchens or high-use areas, now come with integrated bag retainer rings or similar features.
You'll often find these on step-on cans or sensor-activated models. The mechanism is usually a simple but effective plastic or silicone ring built into the inner rim of the bin. You tuck the edges of your trash bag over this ring, which holds it securely in place, preventing it from falling in when you toss something heavy or from collapsing entirely. It's a small feature that makes a huge difference in daily convenience and cleanliness.
When shopping, look for keywords like "bag lock system," "liner retention ring," or "secure-fit lid." Many popular brands in the home organization space include this as a standard feature. It’s a sign the design has really considered real-world use. While not every single bin has it, it's become common enough that you have plenty of stylish, sleek options to choose from that will keep your bag neatly in place and your floor clean.
