What should the width of a shower entry be to ensure accessibility?

For ensuring accessibility, particularly in compliance with guidelines like those set out in the Americans with Disabilities Act (ADA), the width of a shower entry should typically be at least 36 inches. However, in the context of this question, the most accommodating width provided among the choices—22 inches—would be the best option available.

A width of 22 inches allows for easier entry than smaller measurements, which may pose challenges for individuals with mobility devices or other needs. While it may not fully meet the ideal standards found in broader accessibility guidelines, it does provide a reasonable compromise for accommodating a variety of users within the constraints of the options given. Therefore, selecting 22 inches is a more favorable choice than the narrower widths listed.
