How We Chose These Kitchen Storage Picks

We evaluated under sink cans on three criteria: width (must fit standard 9-inch cabinet opening), ease of removing the bin for emptying, and lid performance. We also considered odor control and durability from thousands of owner reviews.

Key Takeaway: For most kitchens, a slim open bucket on a slide-out frame gives the best access and capacity. If you need a larger can, a step-on slim model works, but measure your cabinet height first.

Under Sink Trash Can Buying Guide

Measure Your Cabinet First

Before buying, measure the width, depth, and height of your under sink cabinet. Most cans are 6-9 inches wide. Account for plumbing pipes that may reduce usable space. A slide-out frame requires about 2 inches of clearance on each side.

Choose Your Lid Type

Open buckets are easiest to use but let odors escape. Step-on lids keep smells in but add height and cost. Swing lids can jam against cabinet doors. For under sink use, a lid is optional if you take out trash daily.

Consider Odor Control and Cleaning

Under sink areas can get smelly. Look for cans with charcoal filters or easy-to-clean surfaces like stainless steel or smooth plastic. Removable inner buckets make emptying and washing much easier.

Safety Notes

  • Ensure the can does not block plumbing access or leak paths.
  • Do not overload the can, as it may tip when pulled out.
  • If using a slide-out frame, secure it to the cabinet floor to prevent tipping.
  • Keep sharp objects away from thin plastic bins to avoid punctures.

What to Avoid

  • Avoid cans with lids that require lifting by hand under the sink, as they are inconvenient.
  • Avoid cheap plastic cans that crack or warp from moisture.
  • Avoid cans that are too tall to allow the cabinet door to close.
  • Avoid models with non-removable inner buckets, as they are hard to clean.

FAQ

What size under sink trash can fits most cabinets?

Most standard under sink cabinets can accommodate a can 6-8 inches wide and 12-14 inches tall. Measure your cabinet’s interior width and height before buying.

Do I need a lid on an under sink trash can?

A lid helps contain odors, but if you empty the can daily, an open bucket is fine. Lids add height and can be inconvenient under low cabinets.

How do I clean an under sink trash can?

Remove the bucket and wash with soap and water. For stainless steel, use a mild cleaner. Charcoal filters should be replaced every 3 months.

Final Verdict

The simplehuman 8-Liter Slim Open Bucket is the best under sink trash can for most kitchens because it combines a space-saving slide-out frame, a removable easy-clean bucket, and effective odor control. If you need a larger capacity, the Rubbermaid 7.5-Gallon Slim Jim Step-On is a great value, while the OXO Good Grips 7.5-Quart Slim Waste Bin offers a simple budget-friendly option.
