A 9 gallon trash can sounds simple, but the real question is whether it will slide into the exact spot you have in mind. The two best picks here split cleanly: one is a slim two-pack built to vanish into a pull-out cabinet, and the other is a taller swing-lid bin that hides waste behind a closing top. Before you buy, measure your space and decide if you want an open top or a lid, because that choice drives everything else.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Each bin holds about 9 gallons (a standard kitchen-bin size), but they fit very different homes. Your 9 gallon trash can choice depends on one question: do you need it to slide under a cabinet, or do you prefer a lid that swings open with a push?
Our Picks at a Glance
How To Choose The Best 9 Gallon Trash Can
Picking a 9 gallon trash can is really about matching the bin to one physical spot in your home. A kitchen under-sink cabinet, a bathroom corner, and an office desk gap each demand a different shape, so start with a tape measure before you scroll.
Measure the space, not the gallon count
The two cans here are both marketed near the 9-gallon range, but their heights differ by nearly five inches. The shorter one fits inside a cabinet slide-out, while the taller one stands on the floor. Write down the width, depth, and height of your intended spot, then compare it to each bin’s listed dimensions.
Open top versus swing lid
An open wide mouth makes it easy to toss trash one-handed, which is ideal under a desk or in a busy kitchen. A swing lid keeps waste out of sight and blocks pets from rummaging, but it adds a small motion every time you throw something away. Decide which trade-off you can live with daily.
Think about the bags you already own
Here is the trap most buyers hit: standard 13-gallon kitchen bags are far too large for a 9-gallon bin. Check whether the can takes smaller bags, or whether its opening forces you to stretch a bigger bag almost to the breaking point. This single detail causes the most frustration in real-world use.

In‑Depth Reviews
1. ROOMTEC 35QT Kitchen Trash Can 2-Pack
The two-bin kit that disappears inside a cabinet slide-out
The standout feature here is the fit — buyers report these bins land perfectly inside pull-out cabinet drawers made for trash and recycling, and it is the single biggest reason people buy this set. Each can measures 13.78″L x 11″W x 17.72″H, which is short enough to slide under a sink or into a desk gap while each still holds a full 35 quarts.
Because you get two cans in one box, the value is the real story. Splitting trash and recycling becomes immediate, and the lightweight plastic makes both easy to lift and carry when it is time to empty them. The wide-mouth rectangular opening lets you toss waste without aiming, which suits a busy kitchen or office.
The build holds up to daily use — buyers describe it as sturdy and easy to wipe clean, with a polished finish that looks good in grey. The recurring praise centers on how well each bin fits its intended cabinet spot, and the set arrives with a 90-day warranty in case anything goes wrong.
Why owners love it
- Two bins per order for trash and recycling separation
- Rectangular slim shape slips into tight under-sink spaces
- Lightweight plastic that is easy to carry and clean
Worth knowing
- Open top means waste stays visible between empties
- No lid, so pets can still reach inside
Reach for this if: you have a pull-out cabinet or under-sink slot and want a durable two-can setup for the price of one.
Look elsewhere if: you need a lid to hide waste or block pets, because this design is wide open by intent.
2. Superio Kitchen Trash Can with Swing Top Lid
A swing lid that locks curious pets out of the bathroom bin
The defining trait of this can is its swing top, which closes on its own and keeps waste out of sight. Dog owners are the biggest fans — they report the lid stops pets from pulling papers out and scattering trash, and it even sits neatly on the back of a toilet to stay out of reach entirely.
At 9 gallons (37 quarts) with a 14″L x 11″W x 22.5″H frame, this is the taller of the two bins, so it stands on the floor rather than sliding into a low cabinet. The 2-pound plastic build is rustproof and easy to wipe down, and the beige color is a rare find for people who want a swing-lid model that matches a warmer decor.
Buyers praise the build quality, but two honest trade-offs keep coming up. The top opening is too wide for standard 13-gallon bags (the common kitchen size), so you will have to stretch them almost to the breaking point — as one owner put it, they are “way too difficult to put on and take off without hurting your fingers.” Durability also gets mixed reactions: some owners mention the top breaking after about two weeks and the lid not attaching firmly, so handle the mechanism gently.
What wins people over
- Swing lid shuts on its own and hides waste
- Blocks dogs from reaching trash in bathrooms
- Rustproof plastic with a useful 9-gallon capacity
The honest catch
- Standard 13-gallon bags fit poorly and risk tearing
- Lid hinge durability is the most common complaint
Best for: pet owners and RV users who want waste hidden behind a closing lid.
Who should pass: anyone who uses standard kitchen bags, since the oversized opening makes bagging a struggle.
Understanding the Specs
Capacity vs. physical footprint
A 9-gallon rating tells you how much waste fits, not how much floor space the bin takes. The ROOMTEC stands 17.72 inches tall, while the Superio reaches 22.5 inches — a difference of nearly five inches that decides whether you can stash it under a cabinet or must park it out in the open. Always measure your spot first.
Bag compatibility
When picking liners, the opening size matters more than the gallon label. A 9-gallon can has a much smaller mouth than a standard kitchen bin, so large 13-gallon bags will not drape over the rim cleanly. Instead, use smaller bags or ones made for 9-gallon bins — they sit properly without stretching or tearing at the edges.

Final Thoughts: The Verdict
For the majority of shoppers, the 9 gallon trash can winner is the ROOMTEC two-pack because it delivers two sturdy, cabinet-friendly bins with a fit that owners consistently rave about. If you need waste hidden behind a lid that blocks pets, grab the Superio swing-top instead.
