Causes of Toilet Rocking

There are a few different reasons why a toilet might be rocking back and forth. The most common causes are:

  • Uneven flooring. If the floor beneath the toilet is uneven, it can cause the toilet to rock. This is often caused by settling or shifting of the foundation, or by a poorly-installed toilet.
  • Loose toilet bowl bolts. The toilet bowl is attached to the floor with bolts. If these bolts are loose, the toilet can wobble and rock. This is a common problem with older toilets, as the bolts can rust and become loose over time.
  • Damaged toilet flange. The toilet flange is a metal ring that sits between the toilet and the floor. It helps to support the toilet and prevent it from rocking. If the flange is damaged, it can no longer support the toilet properly, and the toilet will start to rock.
  • Sagging subfloor. The subfloor is the layer of plywood or OSB that sits beneath the finished flooring. If the subfloor is sagging, it can cause the toilet to rock. This is often caused by water damage, pests, or structural problems.
