How long must grab bars be at toilets on the side?

The correct length for grab bars located beside toilets is 36 inches. This dimension is established to provide adequate support and stability for users, particularly those who may have mobility challenges. Grab bars must extend at least this length to allow for a secure grip and to facilitate safe transfers in and out of the toilet area.

A grab bar that is 36 inches long is considered optimal because it can be positioned at a height that is accessible for most individuals and provides enough surface area for users to hold on to while maneuvering. This length effectively enhances accessibility, ensuring that users can safely navigate from sitting to standing and vice versa. Compliance with this dimension is also in line with accessibility guidelines, making it essential in both residential and commercial restroom designs to meet the needs of all users.

The other lengths provided do not align with the established standards for grab bar lengths beside toilets as specified in technical documents and codes related to accessibility, making them unsuitable choices for this application.
