How to replace a toilet seat is quite simple, first you need to determine what style of toilet you have. You will either have to replace a round toilet seat or an elongated toilet seat. In this video, Lou demonstrates a toilet seat replacement using an elongated toilet seat. No matter what type of toilet you’re replacing, you will need the toilet seat fasteners, toilet seat screws, and the toilet seat anchor. Make sure to pay attention to the manual and don’t throw away any old pieces until the new toilet seat is successfully installed!
