Under Sink Trash Can Buying Guide

Measure Your Cabinet

Under sink cabinets vary widely. Measure height, width, and depth. Standard sizes are 9x9x12 inches. Allow clearance for the lid and plumbing. A too-large can won’t fit; too small wastes space.

Consider Material and Odor Control

Steel frames last longer but cost more. Plastic is lightweight and cheap but can absorb odors. Look for a lid with a rubber gasket or tight seal. Some models have charcoal filters for extra odor absorption.

Ease of Cleaning and Maintenance

Removable inner buckets make cleaning easy. Dishwasher-safe is a plus. Avoid models with crevices where gunk can build up. Check that the lid is easy to remove for deep cleaning.

Safety Notes

  • Ensure the trash can does not block plumbing access for leaks or repairs.
  • Choose a model with a stable base to prevent tipping when opening the lid.
  • Avoid sharp edges on metal frames; some have protective coatings.
  • Keep trash bags away from heat sources like garbage disposals.

What to Avoid

  • OXO Good Grips: Lid warping reported after a few months, leading to odor leaks.
  • Rubbermaid Commercial Products: Too large for most under-sink cabinets.
  • Simplehuman 8 Liter: Bulkier, may not fit standard cabinets.
  • Any can without a lid: Odors will escape and attract pests.

FAQ
