What fraction of the required number of toilets can urinals count as for males?

In many building codes and plumbing standards, urinals are recognized as a more efficient option for male restrooms compared to traditional toilets. Specifically, when calculating the number of required toilet fixtures, it is common that urinals can account for two-thirds of the required number of toilets for males. This is based on the understanding that urinals generally have a lower flow rate and are designed for quicker use, which helps in reducing the total number of fixtures needed to accommodate male restrooms effectively.

Therefore, if a certain number of toilets are required, the urinals can be considered to fulfill a significant portion (typically two-thirds) of that requirement, allowing for a more efficient layout and usage of space. This is likely predicated on the assumption that not all males will need to use a toilet at the same time, thus allowing for the reduced number of fixtures.

This standard helps in designing efficient restroom facilities, balancing the needs of building occupants while ensuring compliance with code requirements for sanitary facilities.
