Our Picks at a Glance
How To Choose The Best 3 Gallon Trash Can
Before you pick a small bin, think about the specific spot it will live in and how it will be used. A 3 gallon trash can is all about fitting into a dedicated narrow space, so the exact dimensions and the way the lid opens are just as important as the capacity.
Measure your gap, not just the gallons
The biggest mistake buyers make is focusing on capacity and ignoring the footprint. A can that holds 3 gallons but is 12.32 inches long and 5.63 inches wide will slip into a different spot than one that is 13.1 inches long and 6.9 inches wide. Always measure the intended space and compare it against the listed length and width before ordering, since even an inch can make the difference between a perfect fit and a bin that sticks out.
Pick a lid that matches your routine
Open-top cans are the simplest for quick tosses and easy bag changes, but they expose everything and do nothing for odors. A press-top lid seals smells and keeps pets out, but adds a moving part that can wear out. Swing lids are hands-free in one direction, while motion sensors offer true touchless convenience but need batteries. If you have a dog that noses into trash, a lid that locks securely is the detail that matters most.
Weigh durability and cleaning effort
Your bin’s material determines how long it lasts and how easily you can wipe it down. Heavier plastics like ABS (a tough, impact-resistant plastic) resist cracking and feel sturdier, while basic polypropylene (a lighter, more flexible plastic) is more prone to flexing. A smooth, smooth surface wipes clean with a damp cloth, which helps in a bathroom where dust and moisture are constant. A rustproof or waterproof build adds confidence in humid conditions.

In‑Depth Reviews
1. Rubbermaid Commercial Deskside Wastebasket
Our pick — over 4.5★ from 38,000+ verified ratings; the strongest balance of quality and price.
The crowd-pleasing workhorse that slides under any desk and shrugs off years of abuse.
This is the pick that wins people over on pure quality — over 3,700 owners single out its build, and nearly 1,800 praise the size. The rolled rims add strength where bins usually crack first, and the smooth resin surface wipes clean in seconds.
At 11.75 inches long, 8.25 inches wide, and 12.25 inches tall, it fits under standard-height desks and sinks, and the open top makes bag changes fast. It is a touch wider than the slim picks below, so measure your gap if space is very tight. Buyers report it is “pretty small” but praise how well it holds standard bags without slipping, and the stackable design nests neatly for storage when you need multiple bins.
The trade-off is the open top — no lid to hide smells or keep pets out, so this suits dry office waste more than wet bathroom trash. Buyers rave about the build quality, and for a bin this tough at 3 gallons, it is tough to top as a daily driver.
Built to Last
- Dent, chip, and peel-resistant plastic keeps it looking new
- Fits under standard-height desks and sinks
- Rolled rims add strength at stress points
The Open-Top Catch
- No lid means no odor control or pet protection
- Wider footprint than the slim picks
Reach for this if: you want a nearly indestructible, no-fuss bin for an office, bedroom, or under-sink spot where looks and toughness matter more than sealing.
Look elsewhere if: you need to trap odors or keep a curious dog out, since an open top cannot do either.
2. Anyoifax Slim Garbage Can
The narrowest can here, engineered to nestle into gaps other bins simply cannot reach.
At just 5.63 inches wide, this 3-gallon bin is the slimmest in the lineup, fitting that sliver of space between the toilet and cabinet or the gap beside a desk. It is 8% narrower than the JOYBOS below, so it fits spots the others will not. The transparent green plastic looks modern and fresh, and being BPA-free (free of bisphenol A, a chemical used in some plastics) adds confidence for a bin that lives close to your daily routine.
The shatter-resistant plastic holds up well, and owners mention the color is true to the photos and wipes clean with a damp cloth, even in a laundry room where dryer fuzz builds up. One common note is that it runs “a little bit more narrow than I expected,” so give it a spot that genuinely suits its skinny profile — it holds a decent amount despite its size. Owners also use it as a holder for bathroom cleaners or even a small vase, thanks to the versatile design.
The trade-off is the open top and the mixed feedback on scratch resistance — some owners find it scuffs easily, so it is better for lighter-duty waste than a high-traffic family bathroom.
Skinny-Space Hero: there is no better fit for a true gap-filler, and the BPA-free plastic gives it a cleaner feel than basic bins.
Keep It Light: treat the surface gently, because scratches are the one recurring complaint customers note.
3. JOYBOS Bathroom Trash Can with Lid
A pop-up lid that locks odors inside, making it a favorite for sensitive noses.
This 3-gallon bin stands out for the reasons buyers talk about most: size and fit. Over 100 owners praise the dimensions, and the 5.71-inch width slides perfectly between a toilet and vanity. The press-top lid opens and closes with a light touch, no noise and no lag, and it seals in smells — a huge win for bathrooms where you toss non-flushable items. The 10-liter capacity matches its 3-gallon claim, and the ABS plastic feels sturdy and wipes clean easily.
Dog reviewers point out the lid design stops pets from knocking it open, since the top has to be pulled off with real effort. It is also a smart pick for a small kitchen, fitting into the narrow space beside cabinets while isolating food odors. The included garbage bag gets you started right from the start.
The honest trade-off is the latch — a few owners found the press-down latch can fall out, though the company includes a spare in the box, and many report it lasts a long time without issues. If you want a sealed, discreet bin for a small bathroom, this is a strong mid-range choice.
Why Owners Love It
- Press-top lid seals odors and blocks pets
- Slender 5.71-inch width fits tight gaps
- Sturdy ABS plastic resists wear
Watch Out For
- Latch can occasionally fall out, though a spare is included
- Durability feedback is mixed on the lid mechanism
Choose it for: a bathroom or small kitchen where trapping smells and keeping a dog out matters more than anything else.
Think twice if: you are rough with lids, since the press mechanism is the part most likely to need attention.
4. YAZEES Bathroom Small Trash Can, Set of 2
Two slim bins for the price of one, perfect for separating trash and recycling.
Buyers praise the quality and slim design here, and the 2-pack is the real draw — it lets you put one by the vanity and one by the toilet, or dedicate one to recycling. Each can holds 3 gallons and measures 13 inches long, 6 inches wide, and 11 inches tall, with rounded corners that will not scratch your hands. The thick PP plastic resists drops and deformation, and shoppers say they have held up well for four to five months of daily use.
The narrow shape fits under a bathroom cabinet, beside a sink, or next to a closet, and the hand-holds on the sides make carrying a full bin easy. Owners love that the 6-inch width is too narrow for a dog to get its head in, which is a nice bonus. They also work well for organizing trash versus recycling in the same room.
The trade-off is that some owners find the plastic a bit lighter than they would like, and value-for-money feedback is mixed — a few feel the 2-pack is slightly pricey relative to the build. For the cost of a single premium bin, you get two functional cans, which is the best per-bin value in this lineup.
Two-Room Solution: the 2-pack is the smartest way to cover a bathroom and a bedroom or an office without overspending.
Expect Light Plastic: it is functional and slim, but a few owners wish the walls felt a touch heftier.
5. ABuff Small Lidded Trash Can
A modern black swing-lid bin that hides waste with a simple push of your hand.
This 3-gallon can uses a pivot lid that swings open for hands-free disposal — you can nudge it with a knee or elbow when your hands are full. The slim-sharp design measures 5.7 inches wide, 9.1 inches long, and 13.4 inches tall, and the black finish resists fingerprints, keeping it looking clean in a bedroom or bathroom. The bag lock holds your liner in place, so no messy slips when you pull a full bag out.
Owners say it is great for small spaces and works well for cat litter with scented bags, and the solid black color hides smudges. The lid fits securely with slight pressure, and the smooth swing motion makes it an easy daily partner.
The trade-off here is the lid durability — feedback is mixed on how well the swing lid stays on, and some owners find the lid hard to get on and off quickly. The size also runs smaller than it appears in photos, so check the dimensions before you commit. It is a solid choice for a garage step, bedroom, or bathroom where a quick hand-swipe toss is the goal.
Hands-Free Toss: the swing lid is ideal for moments when your hands are full, and the black finish stays clean-looking.
Be Gentle With The Lid: it fits snugly, but buyers report it can be fiddly to remove quickly and durability varies.
6. funest 3.3 Gallon Bathroom Trash Can
A sleek press-lid bin with an air-pressure trick that makes bagging easy.
Owners talk about the size most — over 150 of them — and this 3-gallon bin delivers a slim 6.9-inch-wide footprint that fits under kitchen sinks and between toilets and walls. The standout feature is the adsorption bagging system: using air pressure difference, the can pulls the bag against the walls automatically, so no more wrestling with a liner that slips down. The press-top lid opens and closes with a touch and seals odors, and it is genuinely dog-proof since the lid has to be pulled off with effort.
The sturdy ABS plastic feels sturdy, and the sleek design hides the bag for a clean look. It ships with 20 garbage bags and an extra snap closure, so you are set up from day one. Owners mention the lid operation is smooth and easy, and the compact size makes it a stylish addition to a bedroom or office too.
The trade-off is durability — a minority of owners flag the latch as a long-term question mark, though most report no issues. It also comes in one size, which is the only complaint some owners have when they want to scale up.
Clever Extras
- Air-pressure bagging fits the liner automatically
- Press lid seals odors and blocks pets
- Includes 20 bags and a spare latch
Consider This
- Latch durability is the recurring question mark
- Only one size available
Pick it if: you hate fighting with trash bags and want a sleek, pet-proof bin that takes care of the messy details for you.
skip it if: you need a larger capacity, since this compact size is the only option.
7. Supteron 3.1 Gallon Narrow Trash Can
A mint-green bin with gold feet that looks more like décor than a garbage can.
The appearance is what wins people over here — nearly 100 owners praise how it looks, and the novel wave stripes add both visual appeal and an anti-slip grip. The polished finish and four gold-plated pivot points give it an elegant, retro feel that blends into a decorated bathroom or bedroom. It holds 3.1 gallons in a slim 5.5-inch-wide footprint, making it one of the narrowest sealed options in this list.
The press-top lid opens and closes easily, and the water-resistant polypropylene build shrugs off humid environments without leaving water stains. Owners use it for newborn diapers and report zero odor escaping, thanks to the tight-sealing lid. The removable inner bucket makes emptying and cleaning straightforward.
The trade-off is the lid mechanism — feedback is mixed, with some owners reporting the lid stops popping up when pressed and a few units failing within a month. The durability concerns mean this is a style-first pick; if you prioritize long-term reliability over good looks, the Rubbermaid or funest are safer bets.
Decor-First Buy: the wave-stripe design and gold feet make this the best-looking bin in the lineup by a wide margin.
Style Over Stamina: a minority of customers note the lid mechanism failing, so treat it gently if you want it to last.
8. onlcuk Motion Sensor Trash Can
A motion-sensing bin that opens in a flash, so you never touch a dirty lid again.
The sensor is the star here — reviewers point out it works flawlessly, opening within 0.1 seconds with a wave of your hand or even a slight knee movement, then closing automatically after 6 seconds. That touchless operation is a genuine hygiene win for a bathroom, and the IPX6 waterproof rating (meaning it resists strong water jets) makes it safe for damp environments. It runs on 2 AA batteries, which are not included, and the lid operates quietly so you will not disturb anyone.
The three included 4.3-inch legs raise the can to 16 inches tall, so you do not have to bend down to toss trash. The modern white body with a wood-grain lid looks sharp, and the internal bag ring hides the liner for a neat appearance. Owners note it is a perfect guest-bath size and that the sensor is sensitive enough to open when you simply walk by.
The trade-off is battery dependency — it is a powered device, so you need to keep AA batteries on hand, and a few owners find the size smaller than expected.
Why It Impresses
- Sensor opens in 0.1 seconds, closes after 6
- IPX6 waterproof for wet bathrooms
- Legs raise it to 16 inches to avoid bending
The Practical Catch
- Needs 2 AA batteries, not included
- Round shape suits open spots, not tight gaps
Reach for this if: you want true touchless convenience and a modern, waterproof bin for a bathroom or dorm.
Look elsewhere if: you dislike managing batteries or need a narrow can for a slim gap.
9. Procade Touchless Trash Can
A black-and-gold touchless can that looks high-end for less, with a sensor that never misses.
The look is what sells this one — owners rave about the black and gold lid with wave stripes that add slip resistance and a premium feel. It holds 3 gallons and works well with reusable grocery bags, making it a versatile pick for a bathroom, kitchen, RV, or laundry room. The motion sensor opens when your hand or any object is detected, then closes automatically after 5 seconds, and it runs on 2 AA batteries that are not included.
The snug lid seals tightly to contain odors, and the removable inner fix ring holds the bag in place and prevents overhanging for a clean look. Shoppers say the sensor is responsive and opens instantly, and the quiet close means it will not startle anyone.
The trade-off is the plastic — a few owners find it lightweight and slightly cheap-feeling, and the fast pop-up lid can occasionally surprise a curious pet. For a touchless can with real visual flair, this is the one to grab.
Style Meets Sensor: the black-and-gold finish delivers a high-end look at a mid-range price, with a sensor owners say works flawlessly.
Mind The Plastic: it feels lighter than it looks, and the fast-opening lid can startle pets, so give it a stable, open spot.
Understanding the Specs
Capacity and How It Fits a Bag
A 3-gallon can is roughly the size of a standard small bathroom bin, but the real question is what size bag it takes. Most slim bins work best with 4-gallon or small kitchen bags, and some come with a bag fix ring or clip to hold the liner in place. A can that measures 3 gallons but is narrow, like 5.63 inches wide, will hold less volume than a rounder 7-inch-wide can, so match the footprint to your space and the bag size to the bin.
Lid Types and Daily Convenience
An open-top bin is the simplest and cheapest, but it offers zero odor control and no pet protection. A press-top lid seals smells and blocks pets, though the mechanism is a moving part that can wear out. Swing lids free up your hands without batteries, while motion-sensor lids offer true touchless operation but require AA batteries and are better for open spaces than tight gaps. Pick the lid based on if you need to trap odors, keep pets out, or simply want the easiest daily toss.
