You ever spend way too much time thinking about garbage? Probably not. It's just a thing you toss stuff into. But then you encounter a simplehuman trash can 45 liter and suddenly you're that person at the dinner party talking about lid dampeners and custom-fit liners. It's weird.
I used to have this cheap plastic bin from a big-box store. The lid never quite closed. It smelled. Every time I changed the bag, I ended up wrestling with a suction-locked plastic mess that eventually tore, leaking "bin juice" all over my kitchen floor. Then I switched. Honestly, the difference isn't just about looks, though the brushed stainless steel is definitely a vibe. It’s about the fact that this specific 45-liter model is basically the "Goldilocks" zone of kitchen waste management. Not too big that the trash rots before it's full, but not so small you're taking it out every five minutes.
The engineering behind the simplehuman trash can 45 liter
Most people think a bin is just a bucket with a lid. They're wrong. If you look at the simplehuman trash can 45 liter—specifically the popular rectangular step-on model—the hinge is actually tucked on the inside. Why does that matter? It means you can shove the bin right up against the wall without the lid banging into your paint job every time you step on the pedal. Most cheap bins need a three-inch gap, which just collects dust bunnies and dropped Cheerios.
Then there’s the pedal. simplehuman claims their steel pedals are engineered to last over 150,000 steps. That’s roughly 20 steps a day for 20 years. I haven't been counting my steps for two decades yet, but the tactile "thunk" feels solid. It doesn’t feel like that flimsy plastic flex you get with cheaper alternatives. When you let go, the lid doesn't slam. It uses air-damping technology to glide down silently. It's kinda satisfying to watch, in a strange, minimalist way.
Why 45 liters is the magic number
Capacity is where most people mess up. You buy a 30-liter bin and you're emptying it twice a day. You buy a 60-liter commercial bin and by the time it's full, it weighs fifty pounds and smells like a landfill.
The 45-liter size—roughly 12 US gallons—fits the standard output of a four-person household perfectly. It handles the pizza boxes, the milk jugs, and the endless stream of junk mail. Specifically, the "liner pocket" models are a game changer. You store the pack of bags right inside the bin. When you pull one out, the next one is right there. It’s a tiny bit of friction removed from your life, but over a year, that adds up to a lot less annoyance.

The liner conspiracy (or is it?)
Let's talk about the elephant in the room: Code M liners.
If you own a simplehuman trash can 45 liter, the company really wants you to buy their custom-fit bags. They don't bunch up. They don't slip. They don't have those ugly "trash bag wings" hanging over the side of your expensive stainless steel bin. Honestly, they are objectively better than the generic drawstring bags you get at the grocery store. They're thicker. They don't rip when you're shoving a sharp-edged cereal box inside.
But they're also more expensive. You can use generic 13-gallon bags. You totally can. But you’ll spend three minutes tucking the excess plastic into the rim so it doesn't look like a mess. It’s a classic "time vs. money" trade-off. Most owners I know start with the generics, get annoyed, and eventually cave to the Code M subscription. It's a bit of a racket, but a very convenient one.
Smudges, odors, and the silver-ion coating
Kitchens are gross. Raw chicken juice, sticky fingers, all of it. The simplehuman bins usually come with an invisible silver-ion coating. It's supposed to resist fingerprints and germs. Does it work? Mostly. You'll still see a smudge if you hit it with buttered fingers, but a quick wipe with a microfiber cloth actually clears it. You don't need heavy degreasers.
For odor control, the seal is the hero. Because the lid sits flush against the rim, it traps the smell of yesterday's onions remarkably well. Some models even have an integrated charcoal filter or a place to tuck an odor pod. It's not a magic "no-smell" box—if you put a fish carcass in there, you’re going to know about it—but for standard day-to-day waste, it keeps the kitchen smelling like a kitchen, not a dumpster.

Comparison: Step vs. Sensor
When looking for a simplehuman trash can 45 liter, you’ll hit the "Step vs. Sensor" crossroads.
- The Step Bin: Reliable. No batteries. Works even if the power is out (obviously). It gives you more control.
- The Sensor Bin: Feels like the future. You wave your hand, it opens. It’s great when you have two handfuls of potato peels.
However, sensors can be finicky. Dogs walk by and trigger them. Small children think they're toys. Batteries die at the worst possible time. For most people, the mechanical step-on version is the "buy it for life" choice. It’s simpler. There’s less to go wrong.
The real-world footprint
You need to measure your space. The rectangular 45L model is roughly 25 inches tall, but with the lid open, it hits about 36 inches. If you’re planning to put this under a kitchen island overhang or a low counter, you’re going to have a bad time. Check your clearances.
Also, consider the "Butterfly" lid version. If you have low counters, the lid opens from the middle like French doors. This significantly reduces the vertical clearance needed. It’s a niche solution but a brilliant one if you’re living in a tight apartment with low-hanging cabinets.
Is it actually worth the $100+ price tag?
That’s the big question. It’s a lot of money for garbage.

But think about it this way: you touch your trash can more than almost any other appliance in your house. You use it more than your toaster, your blender, maybe even your dishwasher. If a product lasts 10 years and removes a tiny bit of daily frustration every single time you use it, the "cost per use" is fractions of a penny.
There are cheaper clones on the market. Brands like Glad or Kohler make similar looking bins. Some are decent. But they often miss the "inner bucket" design or the specific tension in the pedal hinge that makes the simplehuman feel premium. It’s the difference between a car door that shuts with a solid "thud" and one that clatters.
Actionable steps for choosing and maintaining your bin
If you're ready to pull the trigger on a simplehuman trash can 45 liter, don't just grab the first one you see on Amazon. Follow these steps to make sure you don't regret the purchase:
- Measure your "lid-open" height. Don't just measure the bin; measure the space it needs to breathe. If you have less than 38 inches of vertical space, look for the "Butterfly" lid model instead of the standard "Step" lid.
- Decide on the "Liner Pocket" feature. It makes the bin wider and more expensive, but it saves you from digging through the pantry for a new bag every Tuesday.
- Choose your finish wisely. Brushed stainless steel is the classic, but they also offer "Rose Gold" and "Black Stainless." Keep in mind that the standard brushed finish is the easiest to match if you buy other kitchen accessories later.
- Bulk buy liners. If you're going to use the official Code M liners, buy the 60 or 100-pack. The price per bag drops significantly compared to the small 20-packs.
- Clean the base. People forget that liquids can sometimes seep under the inner rim. Every three months, take the inner bucket out (if your model has one) and wash the bottom with warm soapy water to prevent "mystery smells."
- Avoid the sensor model if you have pets. A curious Golden Retriever will spend all day opening and closing a sensor bin, draining your batteries and potentially getting into things they shouldn't. Stick to the pedal.
The reality is that a good trash can won't change your life, but a bad one will definitely annoy you. Moving to a high-quality 45-liter system is one of those "adulting" upgrades that you didn't know you needed until you have it. Once you experience a lid that doesn't bang and a bag that doesn't slip, there's really no going back to the cheap plastic buckets.
