Not all steel litter boxes are the same. Most are mixed with cheap materials that can still trap smell. Keep reading to learn what's really going on, and what to do about it.

Plastic litter boxes smell because the material is porous. Urine and bacteria absorb into it over time, deep into the material where scrubbing can't reach.
That's why the smell never fully goes away no matter how often you clean.
Stainless steel is supposed to solve that. It's non-porous, so nothing absorbs into the surface. You wipe it clean and it's actually clean. That's why hospitals and vet clinics use it.
But that only works if the steel is real. And most of the time, it isn't.

Most steel litter boxes aren't made from pure stainless steel. They're made from alloys — blends of steel and cheaper metals that cut manufacturing costs.
The listings say "stainless steel," but none of them say "non-porous."
When you dig into the fine print, you learn why. The material isn't fully sealed the way real stainless steel is.
It's still porous. And a porous surface traps odor — whether it's plastic or cheap metal.

Nuava isn't made from a cheap alloy blend. It's made from pure, non-porous stainless steel — the same material found on surgical equipment and operating tables.
That's the difference. Other steel boxes look like steel and feel like steel, but the material still lets odor in.
Nuava's surface is completely sealed. Urine and bacteria sit on top, you wipe them off, and they're gone. Not masked. Not reduced. Gone.
A non-porous stainless steel litter box is heavier than a plastic one or a cheap alloy.
That means shipping costs more — and for a lot of cat owners, that extra cost is what stops them from getting the box they actually need.
Because of that, Nuava is covering the full cost of shipping for a limited time. If you've been thinking about making the switch, this is the easiest it's going to get.
