That plumbing was not in any way up to standard. If you've got s-curves in your pipes you shouldn't have anything to worry about with getting this (or cholora, or norovirus) via your toilet from another unit.
I don't think we've actually had any fecal transmission with SARS-2 either, or even had someone successfully culture live virus from a stool sample. We've seen a lot of virus RNA show up in stool from infected patients but that might be due to swallowed saliva. I'd try to avoid contact with other people's feces in any event but the danger here really does seem to be mostly droplets.
