Is your toilet rocking forwards and backwards? In this article, we’ll take you through everything you need to know about why your toilet is rocking and how to fix it.

The most common cause of a rocking toilet is an uneven floor, a loose flange or broken wax ring.

What is the cause of a toilet rocking forwards?

Uneven Flooring

Toilets can rock forwards if the floor beneath them isn’t level. This often happens when the toilet isn’t installed correctly or if there have been changes to the flooring, such as new tiles being laid.

Loose Flange

It is also possible for a toilet to rock if the flange that connects it to the waste pipe is loose. This can be due to a number of reasons, including poor installation or corrosion.

The wax ring that seals the gap between your toilet and the waste pipe can also break over time. If this happens, it can cause your toilet to rock forwards.
