Determining Toilet Handedness

A toilet's handedness (left or right) is determined by the position of the exterior wall/cassette door when the user is seated:

• Left-Handed Toilet: The exterior wall/cassette access is on your left.
• Right-Handed Toilet: The exterior wall/cassette access is on your right.

Note: Please be aware that the accompanying product photograph may not accurately show the correct handed part. Ensure you select your requirement based on the definitions above.
