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

The minimum distance allowed between two water closets, measured center to center, is established to ensure comfortable and practical use of the fixtures in a restroom. A distance of 31 inches ensures that there is enough space for users to access each toilet without feeling cramped or uncomfortable. This measurement also accommodates typical dimensions of standard toilets and allows for adequate spacing for maintenance and cleaning.

Additionally, adhering to the 31-inch standard aligns with commonly referenced plumbing codes and guidelines that dictate minimum requirements for restroom design. By maintaining this distance, restroom facilities can cater to accessibility concerns, promote user comfort, and meet safety regulations, making it a critical detail for both residential and commercial plumbing design. Compliance with these standards is particularly important in public and multi-user restrooms where user experience and ease of movement are paramount.
