What is the minimum distance required from the center of a water closet to a sidewall or partition?

The minimum distance required from the center of a water closet to a sidewall or partition is 15 inches. This measurement is crucial for ensuring adequate space for user comfort and accessibility. Providing at least 15 inches of clearance allows for easy movement and enhances the ability to install and maintain the fixture. It promotes safety by minimizing the risk of awkward positioning or contact with adjacent walls, which can be especially important in more confined spaces.

Regulatory codes and standards typically specify these measurements to ensure uniformity in residential plumbing design. While some designs may accommodate smaller clearances, adhering to the 15-inch standard is advisable to meet safety and functionality requirements across various installations.
