Has anyone who switched from a plastic litter box to a stainless steel litter box noticed that urine in the stainless steel box produces more of an odor?

My cat pees high so I have to use a litter box with tall walls. I switched from a plastic litter box, that never smelled bad, to a stainless steel litter box ,and I smell urine coming from it every day. He’s not peeing over the sides and the litter is the same. I’ve learned that because the plastic is porous, the odor could have gotten trapped in the plastic (which isn’t sanitary).

I clean it at least twice a day and I’ve been wiping the walls with a water/vinegar mixture and just wiped a pet safe enzyme odor remover on the walls too.
