It's not surprising that a toilet seat can show some wear and tear over time, after all, it's used several times a day. If a toilet seat goes up and down four times a day, the hinge moves more than 1,400 times a year. So it's worth paying more for a quality seat as well as a toilet seat hinge to ensure longevity.
There are several toilet types to choose from to suit any bathroom. The most popular type is the close-coupled toilet, which is where the pan sits snugly against the tank. There are also back-wall toilets, wall-mounted toilets, and traditional premium toilets.
There are two main types of hinges, not all types are suitable for all toilets. Top-mounted toilet seats are installed by feeding two bolts into the pot and are used when the bottom of the pot is not accessible, such as in a back-to-wall or one-piece toilet. The bolts on the bottom mount are tightened from below, so unrestricted access to these bolts is required.
You also get a toilet seat with a soft-close hinge (as mentioned before) and a quick-release hinge that makes it easy to remove the toilet seat so you can clean it easily.
