Are stainless steel litter boxes better than plastic ones? For one specific problem, yes: odor that has settled into an old, scratched plastic box. For most other litter box problems, the material makes little difference.
That matters, because stainless steel is often sold as a fix for everything. This guide sorts out what it actually solves, what it doesn’t, and what to do if your cat hesitates to use the new box.
Stainless steel litter boxes are better than plastic at resisting scratches and lingering odor in the box itself, but they don’t fix litter tracking, a box that’s too small, walls that are too short, or a cat that dislikes its litter or location.

What Stainless Steel Actually Fixes
Odor that has settled into an old box. Plastic can scratch from digging and scooping, and worn surfaces make lingering odor harder to remove. Stainless steel is non-porous and resists scratching better, so if your old box smells even after washing, switching can genuinely help.
Wear from daily use. Stainless steel generally resists scratching and wear better than plastic during daily digging and scooping.
Clumps sticking to the surface. Many owners say clumps release more easily from smooth metal than from scratched plastic.
Stainless steel litter boxes are easy to rinse and clean compared to scratched plastic litter boxes.
What Stainless Steel Doesn’t Fix
Odor from the litter or the routine. Stainless steel can’t stop odor being generated in the litter itself. As urine sits, urea breaks down and ammonia odor develops. Litter choice and how often waste is removed matter more here than the material underneath. If a new, clean box starts smelling quickly, look beyond the pan material: the litter, waste sitting in the box and the scooping routine can all be contributing. Our best cat litter for odor control guide covers that.
Litter tracking. Stainless steel doesn’t prevent litter from leaving on your cat’s paws or being scattered as your cat exits. Litter type, box design and a good mat matter more than the pan material. See our low tracking cat litter guide.
A box that’s too small. A cramped steel box causes the same problems as a cramped plastic one. Size matters more than material.
Urine going over the edge. Many open stainless pans have fairly low walls. If urine is escaping, wall height is the fix. Our high wall litter box guide compares heights.
Seams on attached-wall designs. Some high-sided stainless boxes attach separate walls above the steel pan, and urine can escape at that joint. Our stainless steel litter box pros and cons explains what to look for.
A cat that dislikes its litter or location. The material sits under the litter, so it won’t change how a cat feels about the litter itself or where the box is placed.
What If Your Cat Won’t Use the New Stainless Box?
If your cat hesitates to use a new stainless box, consider what changed besides the material.
Too many changes at once. A new box, a new litter and a new spot together is a lot. Keep the same litter and the same location.
The sound. Steel can ring under claws in a way plastic doesn’t. Some owners notice their cat reacting to it at first.
A different size or entry. If the new box has a higher step or a smaller footprint than the old one, that alone can put a cat off.
Give it time. Put the new box next to the old one and leave both out until your cat uses the new one reliably. Our guide to what to do when a cat refuses to use the litter box covers more.
If your cat suddenly stops using the litter box altogether, contact your veterinarian. A sudden change in litter box habits can have a medical cause.
Frequently Asked Questions
Does a stainless steel litter box really not smell?
The box itself is less likely to hold odor. But waste in the litter still smells until it’s scooped, so a stainless box won’t smell fresh on its own if the litter isn’t kept clean.
Are all stainless steel litter boxes the same?
No. Some are simple open pans, while others add high walls, lids or top entries. Some are made entirely from stainless steel, while others combine a steel pan with plastic walls. Entry height, footprint and seams also vary. Our stainless steel cat litter box reviews compare seven by the problem they solve.
Is a stainless steel litter box better than an automatic one?
They solve different problems. An automatic box removes waste for you, while stainless steel is just a material, and most automatic boxes are plastic. If daily scooping is the problem, see our best automatic litter box guide.
Are stainless steel litter boxes bad for cats?
The material alone doesn’t determine whether a litter box suits a cat. Look for smooth, rounded edges, enough room to turn comfortably, and an entry your cat can manage.
