What is the minimum width required for a shower opening to be considered compliant?

The minimum width required for a shower opening to be considered compliant is 22 inches. This dimension is important for ensuring accessibility and safety within the shower space. A width of 22 inches allows for comfortable entry and exit for users, accommodating individuals of various sizes and abilities, including those who may require additional space due to mobility aids.

By specifying a minimum width, building codes aim to maintain a standard that enhances practicality and user-friendliness in bathroom design. Ensuring the shower opening meets this requirement helps to prevent accidents and improve overall usability, thereby supporting the goals of accessibility and safety within residential and commercial plumbing installations.
