Choose the right size and centre distance
Besides the fact that it is important to look at the dimensions of the toilet bowl itself (the width and distance from the centre of the hinge holes to the front), the centre distance is also very important. Perhaps even more important, because if the centre distance is not appropriate, you cannot mount the toilet seat. The centre distance is the distance between the centres of the hinge holes. These are, just like the dimensions of the seat themselves, in principle always mentioned on the packaging or the provider's website.
