How to find replacement toilet seat (American Standard)
Toilet seats are available in a variety of colors and materials, plastic, wood, padded. There are dozens if not hundreds of options.
Your toilet appears? to have an elongated bowl, as opposed to a standard bowl, so you need to make sure you get an elongated seat.
Most seats are universal fit, except for some custom toilets, so you should be able to buy an elongated seat, or a standard, in a color you like. Just two bolts at the back of the seat go though two corresponding holes in the bowl.
You can get soft close hinges to keep it from slamming down.
