Cracked toilet seat hinge: repair seat or replace seat?
I see universal hinge replacements online for $10, but a new seat (low-end) would cost $10-$20.
This is somewhat of a personal decision. My recommendation would be to start by trying to glue the hinge back together if that makes sense. Use a glue that says it works on plastic. Will this work? Maybe, but you probably have an appropriate glue lying around the house somewhere, so there's little actual risk. I think it's likely that it'll break again after a while, but that might give you a few more months of use for free.
If that doesn't work, I'd just buy a cheap replacement. I did a quick look over Lowes, and they don't seem to offer seats with nylon hinges, and while they have &quot;chromed&quot; options, that phrasing sounds dubious, and the design doesn't look strong; I doubt it offers much more in the way of durability over plastic. What it looks like is that paying more money can get you more style (a wooden seat, or a padded seat, or different colors), but not more durability. On the other hand, my experience has been that the cheap seats are actually okay, and won't snap in half after a month or disintegrate when humid. My usual recommendation is to buy the cheapest option that is actually designed to last, and even the cheap seats seem to pass that test.
