How to Replace a Toilet Seat

Ready to make the switch to a decorative toilet seat and lid? You'll want to make sure you take the correct toilet measurements, whether your model is a standard round or an elongated size. Learn how by following along with the videos below, plus find out how to install a toilet seat perfectly the first time around!

A good starting point is to determine whether you own a round or elongated toilet. Round bowls tend to measure 16-17 inches in length, while elongated sizes are typically 18-19 inches long (although they can also be 17 inches in length.)
