grey trash can bathroom

Motion-sensor (touchless) gray trash cans are battery powered. Several listings specify they require batteries (not included), and many note the use of 4 AA batteries or 4 AA alkaline cells as the power source.

Larger kitchen-style gray cans are designed to fit standard tall 13-gallon kitchen bags (13-gallon sizes are commonly referenced). Some mid-size/step cans note compatibility with most 8-gallon bags for their roughly 7-gallon capacity.

Odor-control features include tight-sealing lids, dedicated odor-control lids on some touchless models, and stainless-steel or locking lids designed to trap smells and keep insects out.

Space-saving options include hanging or under-sink cabinet mounts (some with no‑drill hardware), slim rectangular or flush-to-wall designs, and compact bins sized for tight areas like vanity tops or under-sink corners.

Several models include locking lids or lockable step-on designs to keep children and pets out. Foot-pedal operation is commonly paired with a locking mechanism on some step cans for added security.
