What is the minimum spout height for drinking fountains designated for standing individuals?

The minimum spout height for drinking fountains designated for standing individuals is established to ensure accessibility and usability by a wide range of users, including those who may be taller or standing. A height of 38 inches meets the guidelines set forth in accessibility standards, such as those outlined in the Americans with Disabilities Act (ADA). This height facilitates comfortable access for most adults, allowing them to use the drinking fountain without awkward bending or stretching.

In considering the other options, while 35 inches, 36 inches, and 39 inches might seem suitable heights, they do not meet the specificity established for accessibility compliance or practicality. The selection of 38 inches as the minimum ensures that it is within an optimal range for a broader audience, aligning with recognized guidelines for public facilities.
