If your cat is large, or you have more than one, the litter box you already own is probably too small — and if it is plastic, it is probably holding onto a smell you cannot scrub out. An XL stainless steel litter box fixes both problems at once. Steel does not soak up urine the way plastic does, and the extra floor space lets a big cat turn around and dig without hanging over the edge. This guide covers the eight picks worth your attention and tells you plainly which one fits your cat.
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.
One thing to know before you read: this list uses flexible matching for size, so a few picks run larger than the exact dimensions you searched — a bigger box does the same job and often better. Here is the practical way to pick a xl stainless steel litter box that fits your cat, not just your floor.
Top Picks
How To Choose The Best XL Stainless Steel Litter Box
The two numbers that decide whether a box works for your cat are wall height and floor area. Scoops, mats, lids, and pads are convenience features, not deciding ones. Get those two right and the rest is preference.
Wall height decides whether you are still wiping the baseboards
A high-spraying cat sends urine straight backward, so a pan with shallow sides lets it land on the wall behind. Look for walls listed in inches — a 9-inch wall contains most sprayers, and a 12-inch or 14-inch wall handles the extreme cases. Low-sided pans around 4 inches exist for the opposite reason: senior cats and arthritic cats need to step in without lifting a leg.
Floor area should let your cat turn fully around
If your cat has to back out to reposition, the pan is too small. An open pan of roughly 28 inches by 20 inches gives a big breed room to dig and turn. That said, a lid and high walls on a smaller footprint can still work — the right size depends on how your cat moves, not just the label on the box.
Stainless steel is the material, not the marketing
Steel is non-porous, so urine cannot work its way into the surface the way it does in a scratched plastic pan. That is why owners describe these boxes as staying fresher over time. Two trade-offs come with the material: steel shows scratches eventually, and clumping litter can still stick to the bottom if you scoop late. Neither changes the odor story.

Detailed Reviews
1. XXXL Extra Large Stainless Steel Litter Box (KMNSUN)
Our pick — 4.5+★ from 450+ verified ratings; the strongest balance of quality and price.
The box that finally gives a 17-pound cat somewhere to turn without hanging over the edge.
Start with the walls: 14 inches tall. If your cat sprays straight backward, that height is the whole reason to buy this instead of a shallow pan — the urine hits steel and runs down inside, not onto your baseboard. The floor inside is 28 inches by 20.5 inches, which is enough for a heavy cat to turn fully around and dig without backing out to reposition.
The 60-liter capacity means you are not refilling every other day, which is the part multi-cat owners feel first. It weighs 9 pounds, so it stays put on the floor when a cat launches out of it — compare that to the Kichwit at 3 pounds, where a hard exit can slide the pan. Size is the thing owners praise most about this box, and it is the first thing you notice in person: the walls sit high, the footprint is broad, and it reads as a serious piece of equipment rather than a plastic tray.
The honest catch is floor space in the other sense — a box this large needs a real corner, not a bathroom nook. And while the steel wipes clean, scooping late still lets clumps set on the bottom. Both are things to plan for before the box arrives, not defects.
What earns it first place
- 14-inch walls contain high sprayers that defeat shorter pans
- 28″ x 20.5″ floor lets big cats turn and dig in one motion
- 60L capacity cuts scooping and refill frequency for multi-cat homes
- 9 pounds of steel resists sliding on a hard exit
What to plan around
- Needs a genuinely large floor spot — measure before you order
- Clumping litter still sets on the bottom if you scoop late
Buy this one: multi-cat homes and owners of large breeds who are tired of wiping walls.
Check your corner first: the 28-inch footprint is the one thing that can rule it out.
2. AIPERRO Stainless Steel Litter Box with Lid
Small enough for a hallway, tall enough that the spray stays inside.
At 19.3 inches by 14.2 inches by 9.06 inches, this is the compact option on a list full of giants. The 9-inch wall is the trick — it is tall enough to catch urine from a cat that sprays backward, without demanding the floor space of the PAWSIBBLY at 28.5 inches by 20 inches. If your apartment has one good corner and no room for a crate-sized box, this is the shape you want.
It ships with a scoop, which sounds minor until you are kneeling in a hallway at seven in the morning without one. The steel interior releases clumps rather than welding them to the bottom, so daily cleaning is a wipe rather than a soak. Build quality carries this box — the steel thickness and the way the walls meet the pan are what keep it in the conversation against cheaper plastic that warps after a year.
Buyers report that a 30-pound Maine Coon uses it successfully, so a large cat can fit in a compact pan. A huge cat can use a smaller box; it just will not have the same room to stretch out. The trade-off is real: this is the opposite of a spacious footprint, so a multi-cat home should look at the KMNSUN or the Tevila two-pack instead.
Where the money goes: into the steel and the 9-inch walls, not into a jumbo footprint — the box is 3.5 pounds and moves easily if you need to reposition it.
The limit to accept: a single large cat is fine here, but two cats sharing one 19.3-inch pan means more scooping for you.
Reach for it if: floor space is tight and you still need a wall tall enough to stop spray.
Look elsewhere if: you have two or more cats — a single compact pan cannot keep up.
3. Kichwit Extra Large Stainless Steel Open Cat Litter Box
A simple steel pan that does the one job most boxes fail — it doesn’t hold the smell.
The Kichwit is the entry point into stainless steel, and the specs are plain: 23.6 inches by 15.7 inches with 5.9-inch walls. That wall height is the part to weigh carefully. It will contain digging and normal use, but a cat that sprays high will clear it — if that is your situation, the AIPERRO at 9.06 inches or the KMNSUN at 14 inches is the better call. For a scooper who just wants a pan that does not stink, this is the value pick.
Quality and easy cleaning are what owners talk about with this box. Rounded corners and smooth edges mean no sharp lip catching your wrist while you scoop, and the steel wipes down instead of staining. It weighs 3 pounds, which makes it easy to lift and rinse in a utility sink — and also easy for a determined cat to shove out of position, so a mat underneath helps.
Here is the honest split from the review pages: some owners find nothing sticks, others note clumping litter still adheres to the bottom. It is one of the least expensive picks here, and the thin 3-pound build and 5.9-inch walls show it.
The value read: you get real stainless steel and a workable 23.6-inch pan without paying for walls you may not need.
Sized for ordinary use: 5.9-inch sides suit diggers, not high sprayers.
Pick this if: you want steel on a budget and your cat does not spray over the sides.
Keep shopping if: your cat aims high — you need a 9-inch wall or taller.
4. LIHONG Stainless Steel Cat Litter Box
Four inches of wall, so a cat who can’t lift a leg still gets a clean box.
This is the pick for the cat that struggles with height, not the one that clears it. The pan is 19.5 inches by 13.5 inches with a 4-inch side — low enough that a senior, arthritic, or frail cat steps in without effort. The maker lists it for older cats, kittens, and cats with limited mobility, and the low wall is exactly the feature that group needs.
Rubber-padded feet sit on each corner, so the pan grips the floor instead of skidding and the pads protect your hard flooring from scratches. The steel is rustproof and the corners are rounded with no sharp edges, which matters when you are lifting a full pan to rinse it. Cleaning is a hand wash and a wipe, since nothing soaks in.
Size is the contested point on this one — the review sentiment splits, with some owners finding it roomy and others calling it too small for a full-grown adult cat. Read that as a fit question rather than a defect: a slim adult or an older cat fits, while a big breed needs the KMNSUN or the Yangbaga. If your cat is still spry and simply demands more room, this pan will frustrate you both.
Why senior-cat owners like it
- 4-inch side lets a stiff or elderly cat walk in without jumping
- Rubber feet stop sliding and guard your floors
- Rounded edges and rustproof steel make hand washing safe
The size conversation
- 19.5″ x 13.5″ reads small to owners of full-grown large breeds
- No high wall, so it is not built for sprayers
Made for: the older cat or kitten that needs an easy step-in.
Wrong fit for: a big, active cat that wants room to bolt and dig deep.
5. Tevila 2 Pack Stainless Steel Litter Box
Two deep pans in one order — the quiet fix for a two-cat standoff.
Two cats sharing one box is the most common setup mistake in a multi-cat home. This set answers it directly: two pans, each 22.83 inches by 14.96 inches with a 10.24-inch wall, and a 5.04-inch deep metal pan that holds up to 20 liters of litter. Twenty liters per pan means fewer full changes, and the tall walls handle a cat that sprays high.
The shield has an inward-curving rim so you can lift it without pinching, and the pair ships with two scoops and non-slip pads for the floor. The overlap rim on the high walls is what stops urine from finding a gap and running down the outside. For a single cat, the second pan works as a backup or as a way to split solid waste from urine if that is how you like to run your routine.
The steel-and-ABS construction is note — the enclosure components use ABS plastic alongside the stainless pan, so this is not a 100-percent-steel box the way the KMNSUN is. That is the fair caveat. It is also the heaviest set here at 10.1 pounds for the pair, which is a shipping consideration rather than a daily one.
The multi-cat logic: two 20L pans and two scoops in one purchase solves territorial friction far better than a single oversized box.
What you give up: ABS is part of the build, so the enclosure is not pure steel — the pan itself still is.
Best when: you have two cats and want to end the queue at the box.
Skip the set if: you have one cat and one spot — a single XL pan is simpler.
6. PAWSIBBLY XXXL Stainless Steel Cat Litter Box
A 28.5-inch floor plus 12.5-inch walls — room for a Maine Coon and then some.
When a cat is genuinely large, the numbers have to line up on both axes. This box gives 28.5 inches by 20 inches of floor at a 12.5-inch wall, which means a big cat can turn, dig, and cover without spilling over the side. It weighs 9 pounds, so it holds position during an enthusiastic exit. Put it against the AIPERRO at 19.3 inches by 14.2 inches and the difference is stark — this is the box that stops a big cat looking cramped.
The high, leak-proof walls are built for cats that spray like Maine Coons, and the enclosure locks in with a snap-in mechanism for the upper section. It ships with a foot mat and a foot step, plus a metal scoop — the step-and-mat combo catches tracked litter before it spreads, which is the detail that keeps floors clean when a cat leaves the box at speed.
Quality and size are what owners praise most — Owners mention build quality 113 times, and the 9-pound steel pan backs that up., and the 28.5-inch floor is why people who own big cats end up recommending it. The honest consideration is footprint: this is one of the two largest boxes on the list, so a small bathroom will not work. Plan the room before you commit.
Why big-cat owners land here
- 28.5″ x 20″ of floor gives heavy breeds full turning radius
- 12.5-inch walls contain spray from large cats
- Snap-in lid, foot step, and foot mat handle floor mess
- 9 pounds keeps the box anchored
What it asks of you
- Takes up serious floor space — measure the corner first
- Overkill for a small cat or a single kitten
Choose it when: your cat is big, sprays high, and needs the room to prove it.
Overkill if: your cat is average-sized — the extra footprint earns nothing.
7. Yangbaga XXXL Stainless Steel Litter Box with High Sided Lid
The long-handled scoop does the kneeling so your back doesn’t have to.
The scoop is the reason this box stands out in a crowded list. It is a long-handle stainless scoop, which means you are standing and sifting rather than crouching over a pan at floor level. The 28-inch by 20-inch open top gives cats up to 30 pounds room to turn, and the 11.8-inch sides stop litter from flying when they dig.
The pan has a non-slip pad to keep it in place and a polished, scratch-proof surface with smooth rounded edges, so neither you nor the cat catches a sharp lip. It suits indoor corners, balconies, or a courtyard — the open top makes it easy to move between those spots. Odor resistance and general cleanliness are the strongest notes from owners: the steel does not carry a smell between cleanings.
Two things deserve a flag. Size ratings are mixed on this one, with some owners finding it smaller than the 28-inch label suggests — measure your spot and reason from the stated dimensions. Value is also contested, some owners feeling it does not quite match the taller all-steel boxes in the same range. Neither rules it out, but both are reasons to check the dimensions before you order.
The daily win: a long-handle scoop and 11.8-inch walls turn scooping from a chore into a quick stand-up job.
Worth knowing: the 30-pound cat rating fits, but the size reads smaller than expected to some owners — check the 28-inch length against your spot.
Good match for: owners who want a big open box and no kneeling while they scoop.
Buy it deliberately: measure first if size complaints would bother you — the dimensions are the deciding factor.
Know the Specs
Wall Height
Wall height is measured in inches from the inside floor to the top edge. A higher wall catches urine from a cat that sprays backward and keeps litter from clearing the side during digging. Around 4 inches is a low-entry design for senior or arthritic cats. A 9-inch to 14-inch wall is built for sprayers. The taller the wall, the harder the step-in for a cat with limited mobility, so match the wall to the cat’s age and habits, not to the highest number.
Capacity in Liters
Capacity tells you how much litter the pan holds before you refill. A larger pan, like the 60L KMNSUN or the 36L Lietom, means fewer full changes and a deeper bed for digging. A 20L pan such as the Tevila still works for one cat but needs more frequent topping up. Match capacity to your cat count — one cat can live with a modest pan, two cats want volume.
Floor Area
Floor area is the length and width inside the pan. A cat should be able to turn a full circle without hanging over the edge. A 28-inch by 20-inch floor gives a large breed that room. A 19-inch by 14-inch pan may suit a smaller cat but feels cramped for a heavy one. Measure the floor spot you have before ordering, because footprint is the spec that decides whether the box fits your home at all.
Stainless Steel versus Plastic
Steel is non-porous, so it does not absorb urine or hold odor the way plastic does once plastic scratches. Steel also resists scratching and lasts through daily digging. The trade-offs: steel is heavier to lift when you rinse a full pan, and it costs more than plastic. Clumping litter can still bond to the bottom if you scoop late, so the material is not a substitute for a daily scoop.

The Bottom Line
For most owners shopping for an xl stainless steel litter box, the KMNSUN XXXL is the pick — its 14-inch walls and 28-inch by 20.5-inch floor solve both the spray problem and the cramped-cat problem in one box. If your floor space is the constraint, the AIPERRO gives you a 9.06-inch wall in a much smaller footprint. For two cats, the Tevila two-pack ends the queue at the box. And if the daily scoop is what wears you down, the Yangbaga with its long-handle scoop is worth a serious look. Start by measuring the floor spot and your cat, and the right box usually picks itself.
