It was loose when we moved in, and broke completely a couple of weeks later.
I looked up a video on YouTube how to fix it, and after initially thinking the hinges only came with an entire new seat, found that you could order a “fixing kit” which had all of the essential parts seen in the video.
The result is satisfactory.
My toilet seat has a damper in it, kept the lid from slamming. Seems to be wearing out, the seat will freely move now and the lid is getting noticeably easier to move.
Those dampeners irritate me irrationally. I have one of these on my fridge door and I need to apply some pressure in order for it to close.
On the toilet seat it’s kind of nice…until you get used to it taking some muscle to close and then you not only drop but actively slam some other toilet shut.
