What is the maximum allowable temperature for a shower head?

The maximum allowable temperature for a shower head is 110 degrees Fahrenheit. This standard is set to prevent the risk of scalding injuries, particularly for vulnerable populations such as children and the elderly. Water at temperatures above 110 degrees can be painful and can lead to serious burns in a very short duration of exposure.

In residential plumbing codes, maintaining a safe temperature for water delivered from shower heads is crucial for both safety and comfort. Many plumbing standards emphasize that hot water systems should be designed to allow for safe usage in everyday settings, making 110 degrees a logical and safe upper limit for shower applications.

This temperature limit helps ensure that users can enjoy their showers without the risk of injury, promoting both safety and accessibility in residential plumbing design. The other temperatures listed exceed this guideline, which is why they are not appropriate for shower use.
