When choosing the shape of your toilet seat, you want to make sure it fits perfectly on the toilet bowl. Both elongated and round toilet seats come with their pros and cons.
For instance, elongated/oval seats are easy to clean and offer more sitting space but aren't suitable for washrooms with limited space. They are also a bit expensive.
On the other hand, round toilets or round toilet seats are perfect for bathrooms with limited space and are pocket-friendly but maybe less comfortable and challenging to clean. Therefore, before comparing the options in the market, you should know how to differential between elongated and round toilet seats.
While many people can quickly tell round toilets from elongated toilets, it might not be that obvious for some. If you can't easily distinguish between the two, you should measure from the front of the toilet bowl to somewhere at the center of the mounting holes.
For example, an elongated toilet seat measures 18.5″ while a round seat measures 16.5.” You can then compare your toilet bowl measurements to the standards sizes of toilet seats and choose one that will fit perfectly.
