Best metal litter boxes in 2026: 10 stainless steel picks compared

If you’re tired of replacing scratched-up plastic every year, a stainless steel litter box won’t absorb odor, won’t harbor bacteria in claw grooves, and with proper care, can last two decades or more. My pick for most households is the PawsPik Stainless Steel Cat Litter Box XL with Metal Scooper — it’s genuine 304-grade steel (the corrosion-resistant grade that actually matters) at a fair mid-range price, with a scooper and footboard included so you’re not hunting for accessories on day one.

But “stainless steel” isn’t one product category. The ten boxes below span open pans, enclosures, top-entry designs, and a matched 2-pack, and they’re not interchangeable. Here’s how they stack up.

Best overall: PawsPik Stainless Steel Cat Litter Box XL with Metal Scooper

This is 304-grade stainless steel, 24-gauge, which matters more than most listings let on. Per industry sourcing, if a product description doesn’t explicitly say 304-grade, it’s almost certainly the cheaper 201-grade. 201 is more porous and starts rusting and trapping odor within a year or two of ammonia exposure. PawsPik states the grade up front. The pan measures 23.75 x 15.75 x 12 inches with the included optional lid, holds roughly 37 liters of litter (about 30 days for one cat, 15 for two), and comes with a metal scooper and a footboard to catch litter off paws.

Pro: The corrosion resistance you’re actually paying for is verifiable, not marketing language, and not having to buy a separate scoop is a small but real convenience.

Con: Some owners find a metal scoop scraping a metal pan is unpleasant to hear and use daily; you may end up swapping in a plastic scoop anyway. The footboard also needs its own wipe-down or it becomes another dirty surface.

Best budget pick: Kirecoo Stainless Steel High-Sided Cat Litter Box XL

At the lowest price in this roundup, this is the simplest entry point into steel: an open-top pan with 5.7-inch high sides, non-stick smooth finish, and no enclosure to fuss with. Dimensions run 23.43 x 15.55 x 5.7 inches, and Kirecoo positions it as multi-cat capable.

Pro: Full visibility into the box means you’ll notice changes in your cat’s litter habits faster, which matters since vets increasingly flag litter box behavior as an early health signal.

Con: No hood means no splash or scatter control, and at 5.7 inches the sides are the shortest of the high-sided boxes here — a determined kicker can still clear them.

Best for maximum scatter control: iPrimio Ultimate Stainless Steel XL Litter Box with Enclosure

The iPrimio pairs a stainless pan with a detachable 6-inch plastic enclosure, so you get steel’s odor resistance in the tray plus a physical barrier against litter flung by enthusiastic diggers. The pan alone is 23.5 x 15.5 x 6 inches; with the enclosure clipped on it’s 12 inches tall. Rounded, nonstick edges mean litter doesn’t catch in corners the way it does in molded plastic pans.

Pro: The enclosure is removable, so you can run it open-pan for a senior cat and add walls back for a messier housemate.

Con: It’s the heaviest box here relative to its footprint, which is a real problem when it’s full and needs moving for a deep clean. Owners also report the manufacturer’s label leaves a sticky residue that takes some effort to scrub off.

Best for leak containment: WoofiGo Enclosed Stainless Steel Cat Litter Box with Lid XL

If you’ve got a high-sprayer, the failure point in most boxes is the seam where pan meets wall. WoofiGo’s curved-seam construction is built specifically to stop urine from finding a gap, paired with a 6-inch ABS enclosure that buckles onto the pan instead of just resting on top. Total assembled height is 13 inches, with sides listed at 12.5 inches, and it holds up to 20 liters of litter. It also has a tracking-proof pedal entry with litter-catching grooves.

Pro: The buckle connection keeps the enclosure from sliding off mid-use, which is a common complaint with clip-on hoods generally.

Con: It’s another heavy full-steel-plus-plastic unit, and the pedal feature is hit or miss — plenty of cats just walk over it without engaging it as intended.

Best one-piece design: Yangbaga Stainless Steel Extra Large High-Sided Litter Box

Every seam is a potential leak point, so Yangbaga skips the pan-plus-enclosure approach entirely and molds the whole thing as one continuous deep tray, 8 inches high on all sides. There’s no assembly, and no gap between floor and wall where urine can wick through and start corroding metal from the inside.

Pro: Single-piece construction is the simplest to keep genuinely leakproof, and there’s nothing to reattach or realign after cleaning.

Con: 8 inches is a serious step up for older cats or kittens with limited mobility, and a deep pan means more litter volume to scoop through on cleaning day.

Best for aggressive diggers: Kirecoo Stainless Steel XXL Cat Litter Box High Sides

Kirecoo’s XXL variant pushes sides to 7.68 inches, the deepest open-pan option in this lineup, aimed squarely at large breeds and cats who dig with real enthusiasm before settling. Dimensions are 23.43 x 15.55 x 7.68 inches, and the smooth non-stick surface is meant to speed up scooping despite the extra depth.

Pro: It’s versatile enough that some owners use it for rabbits or ferrets, not just cats.

Con: The height that stops digging debris from flying out is the same height that can deter a senior or arthritic cat from stepping in comfortably. Deeper pans also mean more surface area to scoop, which adds a minute or two to daily maintenance.

Best for privacy with minimal odor trapping: Exquisicat High-Sided Stainless Steel X-Large with Lid

Exquisicat’s XL comes with a removable plastic lid rather than a full enclosure, striking a middle ground between open-pan simplicity and full containment. It measures 23.7 x 16 x 10.4 inches, uses heavy-duty stainless steel with a rust-resistant finish, and is sold exclusively through PetSmart, which means straightforward returns and customer service if something arrives damaged.

Pro: The lid lifts off entirely for cleaning, so you’re not fighting a hinge or buckle system.

Con: Any lid traps some moisture, and stainless steel’s odor-neutral advantage is partly offset once you seal humidity inside a covered space. It’s also heavier than the equivalent open-pan Exquisicat model.

Best small-footprint option: Exquisicat High-Sided Stainless Steel Litter Box Large

Not every household needs an XL box. This is Exquisicat’s standard large size at 19.5 x 13.6 x 6.02 inches, heavy-duty steel with the same non-stick, rust-resistant finish as its bigger sibling, and it’s the lowest-priced steel box sold through PetSmart’s own line.

Pro: Sized right for a single average-sized adult cat without wasting floor space you don’t have.

Con: It’s genuinely too small for large breeds or true multi-cat use — the AAHA’s rule of thumb calls for a box at least one and a half times your cat’s nose-to-tail length, and most large cats will outgrow this.

Best top-entry design: PawsPik Top Entry Stainless Steel Litter Box XL

PawsPik’s top-entry model fully encloses the pan and uses a textured lid that doubles as a litter-catching surface: your cat exits through the top opening (9.6 inches across) and sheds loose granules onto the textured lid on the way out rather than tracking them across your floor. It’s built from 304 stainless steel with a plastic top, measuring 23.6 x 15.7 x 15.7 inches, and comes with a scooper and brush.

Pro: This is about as much scatter and privacy control as a litter box format offers, and the 304-grade base means it won’t be the weak link.

Con: Top-entry boxes have a real learning curve. Cats used to a walk-in format, especially older or heavier cats, may need weeks to adjust or may refuse it outright.

Best for matched multi-cat setups: Kirecoo 2-Pack Stainless Steel Litter Box with Lid Large Enclosed

Multi-cat households are usually told to run one box per cat plus one spare, and buying enclosed steel boxes one at a time gets expensive fast. Kirecoo’s 2-pack solves the math directly: two large enclosed boxes (19.49 x 13.6 x 11 inches each) with plastic lids, anti-slip mats, and scoops included, all in one purchase.

Pro: Genuine bundle value if you need two boxes anyway, and the anti-slip mats stop the boxes sliding around during vigorous digging.

Con: Plastic lids again mean you’re not getting steel’s full odor-neutral benefit, and two 19-inch-footprint boxes take up more combined floor space than most apartments have to spare.

How to choose a metal litter box

Check the steel grade before anything else. 304-grade stainless resists corrosion because its chromium content forms a self-repairing oxide layer on the surface. 201-grade lacks that same resistance and will start rusting and holding odor within a year or two of regular ammonia exposure. If a listing doesn’t say 304, assume it’s not.

Match wall height to your cat’s actual behavior, not the biggest number available. High-sprayers and enthusiastic diggers benefit from 7-8 inch sides like the Kirecoo XXL or Yangbaga. Senior cats or kittens need lower entry points, closer to the 5.7-inch Kirecoo or the open Exquisicat.

Decide how you feel about enclosures. A hood or lid cuts down on scatter and gives shy cats privacy, but it also traps moisture, which can partially offset steel’s natural odor resistance. If odor control is your top priority, an open pan often outperforms a sealed one, counterintuitively.

Size it to the cat, not the marketing label. Veterinary guidance from AAHA suggests a box at least one and a half times your cat’s nose-to-tail length, which means most “XL” boxes are still adequate rather than oversized for a large breed.

Budget for weight. Every box in this category is heavier than plastic, and full-size enclosed models are heavier still. If you have mobility limitations or need to move the box often for cleaning, that weight is a real daily friction point, not a footnote.

Best cat litter for odor control

The box material matters less for odor than the litter you put in it. If odor is your main frustration, switching litter types usually outperforms upgrading the box, since unscented clumping litter that you scoop daily outperforms almost any box material on smell alone. Stainless steel helps because it’s non-porous and won’t itself absorb odor the way scratched plastic does, but it’s a complement to good litter, not a substitute for it.

Cat litter oil stain: how to remove it from a metal box

Oil and urine residue on stainless steel usually lifts with warm water and a mild dish soap, applied with a soft cloth rather than an abrasive pad. Avoid steel wool or harsh chemical cleaners: they scratch through the thin chromium oxide layer that keeps the steel corrosion-resistant, and once that layer is compromised, rust and odor-trapping rough patches can follow. For stubborn stains, a paste of baking soda and water left to sit for a few minutes before wiping usually does the job without damaging the finish.

Self-cleaning litter box brands and whether they fit metal boxes

Self-cleaning litter boxes and metal open-pan or enclosed boxes are two different product categories, and virtually none of the automated brands on the market build their mechanisms around stainless steel pans, because the moving rakes and sifting mechanisms are engineered for molded plastic. If automation is your priority, that’s a separate buying decision from the one this guide covers; if odor control, durability, and hygiene are your priority, stainless steel wins on all three without any moving parts to maintain or break.
