Kitchen Trash Cans

The best childproof trash cans

There is no such thing as a certified childproof trash can, so the honest question is how long the lid holds a determined toddler up. Everything here answers that with a physical latch rather than a heavier lid.

The short answer

Buy the simplehuman 50L Semi-Round Step Can with Slide Lock. The slide lock holds the lid to the body, so the pedal stops working until an adult releases it - the one mechanism here that defeats a toddler without defeating you. The budget pick is the Encased Trash Can Lock bungee, which costs a fraction of a new can and turns the can already in your kitchen into one that does not open. For a nursery specifically, the Ubbi Steel Diaper Pail has a childproof lock built into the sliding lid.

Nothing here is certified for child safety, and no manufacturer in this category claims it is. What these do is add a step a small child has not worked out yet, which buys you the months between crawling and reasoning.

What actually stops a toddler

In rough order of how long each one holds, based on how the mechanism works rather than on any test we ran:

A lid that latches to the body. The lid and the can become one object. This is the simplehuman slide lock and the lockable lid on the Hefty step can, and it is the only approach that survives a child who has learned to stand on the pedal.
A sliding lid with a lock tab, as on the Ubbi. There is no pedal to stand on and no lid to flip - a small child has nothing obvious to pull.
A tensioned strap over the lid. The Encased bungee was designed for raccoons, and the hand strength it needs is well past a toddler. It is ugly on a kitchen can and brilliant on a garage or utility can.
Weight and soft-close do nothing. A heavy damped lid is a nicer product, not a safer one. Children open soft-close lids first because they move slowly.

The same logic covers the other household member who raids the trash: see the best dog-proof trash cans and how to keep dogs out of the trash, which overlap this list almost completely.

Who each pick is for

The picks in full

01 — Best for pets

simplehuman 50L Semi-Round Step Can with Slide Lock

The same semi-round shape with a slide lock that physically holds the lid shut against a determined dog.

Capacity: 50 liters / 13.2 gallons
Lock: Mechanical slide lock
Pedal rating: 150,000 steps (manufacturer figure)
Body: Plastic
Lid: Soft-close (Lid Shox)

Dogs do not defeat trash cans by cleverness, they defeat them by weight — nosing the lid until it lifts. A mechanical slide lock removes that possibility entirely, and unlike a strap it does not need re-fitting every time you empty the can. The plastic body also survives being knocked over, which a brushed steel one does not, cosmetically.

What we'd flag: the lock is a conscious action. You have to slide it every single time, and the first week you will forget. If you know you will not do it, buy a can with a heavier lid instead.

02 — Best cheap locking can

Hefty 12 Gallon Step Trash Can with Lockable Lid

A plastic 12-gallon step can whose lid actually locks to the body — the cheapest honest answer to a dog or a toddler in the trash.

Capacity: 12 gallons / 48 quarts
Dimensions: 17.6" L x 11.7" W x 23.6" H
Lid: Lockable to the body
Pedal: Step-to-open, hands-free
Included: 40 Hefty trash bags
Material: Heavy-duty plastic

A heavy lid is not a lock. What stops an animal is a mechanical catch between the lid and the body, and that feature normally costs premium-can money. This has it on a 48-quart plastic step can for the price of a few boxes of bags: step to open, and the lid locks shut again rather than resting on a lip. Forty Hefty bags come in the box, which is unusually honest for a can that cheap — it arrives working.

What we'd flag: 12 gallons is a gallon short of the 13-gallon bag the whole category is built around, so a standard tall-kitchen bag will overhang a little. It is also plastic, so it scuffs where a steel can would dent, and the lock is a catch rather than a latch a large determined dog could not eventually work.

03 — Best diaper pail overall

Ubbi Steel Diaper Pail

The steel diaper pail that runs on ordinary kitchen bags, so the odor control is in the body rather than in a subscription.

Capacity: About 20 large or 55 newborn diapers
Bags: Any standard kitchen trash bag
Body: Powder-coated steel
Seal: Silicone seal ring
Lock: Childproof
Dimensions: 8.4" W x 19.5" H x 11.4" D
Warranty: 3 years against manufacturing defects

Two design decisions do the work. The body is powder-coated steel rather than plastic, and steel does not absorb the odor compounds that make a two-year-old plastic pail smell even when it is empty. The lid slides rather than swings, so it displaces almost no air when you open it — a swinging lid pumps the pail's headspace into the room every time. A silicone seal ring closes the gap, a childproof lock keeps toddlers out, and Ubbi states a three-year replacement warranty against manufacturing defects.

What we'd flag: a sliding lid has a small opening, and you push each diaper through it with your fingers. Parents who want to drop a diaper in without touching the pail should look at a foot-pedal model instead.

04 — Best cheap raccoon fix

Encased Trash Can Lock, Bungee Cord (30-50 gallon cans)

A tensioned nylon bungee that holds the lid down on a can you already own, for a fraction of the cost of replacing it.

Fits: 30-55 gallon round or square cans
Material: Heavy-duty nylon bungee
Installation: No tools

Before you buy a new can, try the strap. A raccoon opens a bin by lifting the lid with its weight on the rim — a bungee under tension defeats that directly, and this one is sized for the 30-55 gallon cans most households have. It fits round or square bodies and needs no tools.

What we'd flag: you have to re-fit it every single time you use the can, and everyone in the household has to. One person who cannot be bothered undoes the whole thing.

Placement beats hardware

Inside a cabinet is the strongest answer. A pull-out behind a doored cabinet with a standard child latch is more secure than any free-standing can, and it solves smell and looks at the same time - the best under-sink pull-out trash cans.
Move the can off the traffic line. A can beside the dishwasher gets opened fifty times a day, including by the child. A can at the end of the run gets opened by adults.
Do not put the dangerous things in the kitchen can. Batteries, razors, medication and cleaning refills belong somewhere that is not the can a child is actively trying to open.
A can that does not slide is a can that does not tip. How to keep a trash can from sliding is the companion fix once a child starts pulling on the lid.

The two we would buy: the slide-lock simplehuman if you are replacing the can, the Encased strap if you are not.

Common questions

What is the best childproof trash can?

The simplehuman 50L Semi-Round Step Can with Slide Lock. The lock holds the lid to the body so the pedal does nothing until an adult releases it, which is the only mechanism here that survives a child standing on the pedal.

Are any trash cans certified childproof?

No. No manufacturer in this category claims child-safety certification. What these products add is a latch that a small child has not worked out yet.

Can you childproof a trash can you already own?

Yes, and it is the cheapest route. A tensioned bungee lock made for raccoons needs more hand strength than a toddler has, and it fits most 30 to 50 gallon cans.

Is a soft-close lid safer for children?

No. A soft-close lid is slower, which makes it easier for a child to open, not harder. Damping is a comfort feature, not a safety feature.

What about a diaper pail instead?

In a nursery, yes. The Ubbi has a childproof lock in its sliding lid and no pedal to stand on. In a kitchen it is too small to be the main can.

Does a pull-out cabinet can count as childproof?

With a standard cabinet latch on the door, it is the most secure option in a kitchen - the can is behind a door rather than behind a lid.
