That's a classic kitchen frustration! For a tall, narrow bin, the main issue is the bag slipping down inside. Here’s the best, simplest way I've found that works like a charm.
First, open your standard plastic trash bag and line the bin as usual, letting the excess bag drape over the top rim. Now, here’s the key: take two or three sturdy binder clips or even strong chip bag clips. After the bag is in place, clip the excess plastic from the bag directly onto the *inside* rim of the bin, spacing the clips evenly around the circumference. The clips grip the plastic firmly to the bin's inner wall, creating anchor points that prevent the entire bag from collapsing inward when you toss in waste.
Why does this work better for narrow bins? The friction from the clips on the inner wall provides upward support that the smooth sides of a narrow can lack. For bins with a handle or lip, you can sometimes hook the bag's drawstring under it first for extra security before adding the clips. This method requires no permanent modification, uses items you likely already have, and creates a taut, reliable liner that stays put until it's full. No more fishing a bag out from the bottom!
