Understanding Wheelbase: A Key to Choosing the Right Toilet Seat
Let’s start by defining what wheelbase means in the context of toilet seats. Wheelbase refers to the measurement between the centers of the two holes where the screws attach the seat to the bowl. It’s essential to understand this concept to avoid mistakes when selecting a toilet seat.
Toilet Seats with Non-Standard Wheelbase
In this article, we’ll explore a selection of toilet series with unique wheelbase measurements that don’t fit the standard range. Typically, toilet seats have a wheelbase between 14 and 16 cm. However, some series have measurements that fall outside this range, such as 8, 10, 12, 19, 20, 21, 23, and 27 cm.
