I bought three hampers before I figured out that width is the only spec that matters. Not capacity, not fabric, not whether it looks like a woven basket from a magazine. If it doesn't fit in the gap between the toilet and the wall, it's useless, no matter how cute.
The thing is, bathroom corners are weird. You think you have space, then you measure and it's 11 inches and the hamper is 13.5. So before you click anything, grab a tape measure and find the exact spot you're planning to stuff it. Write the number down. Trust me, you'll forget.
The Width Rule
For a small hamper for bathroom, width is king. Most bathrooms have a tight spot next to the toilet or under the sink. If your gap is 12 inches, a 13-inch hamper is a no-go. It won't slide in, it will block the door, or it will stick out and you'll bang your hip on it every morning.
I learned this the hard way. My first hamper was a pop-up cube, 13 inches square. It looked fine online, but it sat in the middle of the floor because my gap was only 10.5. It didn't fit anywhere else. I ended up returning it and getting a Popup Hamper: I Tested 5, and Only One Survived My Weekly Laundry that collapsed flat—but even then, the dimensions were tight.
So the rule is: measure the exact spot, then subtract an inch. If the hamper is 12 inches wide and your gap is 13, you're fine. If it's 12.5 and your gap is 12, you're out of luck.
Capacity You Can Actually Use
Another trap: tiny hampers that hold nothing. A 10-gallon hamper sounds small, but it fits about a week's worth of towels and underwear for one person. If you're sharing a bathroom with a partner, double that. I'd rather have a hamper that's 12 inches wide and 18 inches tall than a wide, short one that takes up floor space and holds one load.
Height matters too because hampers with lids are taller. If you're putting it under a sink, you need to measure the clearance. I nearly bought a 20-inch-tall hamper for under my pedestal sink, but the clearance was 15. That would've been a disaster. So measure height as well, especially if you're tucking it away.
Materials That Don't Drive You Crazy
After a month of use, I can tell you that fabric hampers with a flexible frame are a pain. They sag, they tip, and they collect dust. A rigid plastic or wicker hamper is easier to clean, but wicker snags towels if it's rough. And metal frames? They rust in humid bathrooms unless they're coated.
My current one is a slim plastic hamper with a lid. It's 12 inches wide, 15 inches tall, and holds about 12 gallons. It doesn't look fancy, but it fits in the corner, it doesn't tip, and I can wipe it down with a Clorox wipe. That's all I need.

The Lid Debate
If you're putting this in a bathroom, get a lid. It hides the pile of socks and keeps the room from smelling like a locker room. But lids add height and sometimes width. A bamboo lid with a metal hinge looks nice but can be a dust trap. A simple plastic lid that lifts off is fine. I'd skip the sliding lid—it jams and you'll end up leaving it open anyway.
If you want a lid but you're short on space, look for a hamper that's slightly narrower at the top. I've seen ones with a tapered design that still holds a decent amount. But always check the actual bottom width, not the top.
Who Should Skip This
If your bathroom floor space is less than 10 inches wide, don't bother with a floor hamper. Get a hanging laundry bag on the back of the door or a wall-mounted option. Also, if you're someone who does laundry every other day, you don't need a big hamper—a slim one is fine. But if you try to stuff two weeks of clothes into a 10-inch-wide hamper, it will bulge and fall over.
I remember a friend who ordered a hamper for her bathroom without measuring. It arrived, and it was 16 inches wide. It sat in her hallway for a month before she returned it. Don't be that person. Grab a tape measure, find the gap, and check the width. That's the whole trick.
If you're still stuck on style, the Pink Plastic Hamper: What $20 vs $60 Actually Gets You shows why the cheap one is often the smartest buy. But for a small bathroom, the width is the dealmaker.
Measuring once will save you a week of returns. And if you already have a Laundry Hamper for Small Bathroom: 12 Inches That Made the Difference, you get why I keep harping on it.
