What is the minimum distance between two water closets, center to center?

The minimum distance between two water closets, measured from center to center, is established in plumbing codes to ensure functionality, comfort, and accessibility. A distance of 31 inches is the standard requirement. This measurement allows sufficient space for users to sit comfortably without feeling cramped and also facilitates maintenance and cleaning in the restroom area.

Choosing a distance that is too small could lead to accessibility issues, decreased user satisfaction, and difficulties in performing maintenance tasks. By adhering to this minimum distance, plumbing design can achieve a balance between the efficient use of space and the practical needs of users.
