How far from the center of a water closet should it be from a sidewall?

The correct distance is 12 inches from the center of a water closet to the sidewall, as specified by plumbing codes and regulations. This standard measurement ensures that there is sufficient space around the toilet for comfortable use and maintenance.

A distance of 12 inches allows enough room for the installation of grab bars in accessible bathroom designs, if needed, and provides adequate space for cleaning and accessibility. Furthermore, this measurement helps prevent any potential issues with adjacent fixtures, ensuring that they do not interfere with the functionality of the toilet.

This standard spacing plays a critical role in both residential and commercial plumbing layouts and is widely accepted in plumbing practices to facilitate comfort and accessibility for users.
