Americans With Disabilities Act (ADA) Grab Bar Installation Guide

When installing a grab bar in your home, it is crucial to determine the most appropriate height for the intended user. 

This is not as easy as it sounds. If it’s a rail to get out of a bath, for example, determine the height, not only the most effortless reach from a sitting position but also the height that will most help the user attain an upright position.

The Americans with Disabilities Act (ADA) offers standards and excellent guidelines for installing grab bars. These standards ensure their universal accessibility. 

Commercial facilities, public accommodations, and government facilities use these guidelines, but they can apply to domestic properties too. These standards vary depending on the type and location of grab bars.

Installing the grab bars at the wrong height will defeat the object of the installation, which is to offer help and stability to those with mobility or balance problems.

Types of Grab Bars

There are three types of grab bars, vertical, diagonal, and horizontal. 

ADA guidelines specify that horizontal grab bars be installed on the side and rear wall of the toilet.  Vertical grab bars are useful for people who have arthritis, as they offer a more comfortable grip.

Most domestic grab bars are installed inside the house. For outdoor installation, diagonal grab bars are often used. The diagonal grab bars can accommodate different installation angles depending on the slope of the stairs or path.

Vertical grab bars are installed vertically to accommodate the height of as many users as possible. They should be installed in places where users need to get from a sitting to a standing position. 

It’s best to use a textured grab bar for added grip and prevent the user’s hands from slipping.

Apart from the direction they go, there are different styles of grab bars, including:

  • Straight grab bars
  • Entrance grab bars
  • Wave-style grab bars
  • Grab bar towel rack
  • Grab bar toilet paper holder

Grab Bar Height Guide

Below is a detailed guide on the ideal grab bar installation height. The height depends on the grab bar’s location.

For horizontal grab bars being installed in a shower or toilet, the installation height range is 33 to 36 inches from the floor. If you have a transfer shower, the vertical grab bar’s bottom must be 3 to 6 inches above the installed horizontal grab bar. 

The ICC/ANSI A117.1 Accessible and Usable Buildings and Facilities states the required positioning for vertical grab bars. The installation guides are:

  • A vertical grab bar 18 inches minimum in length mounted along the side wall.
  • Centerline of the bar, to be located 39 inches minimum and 41 inches maximum from the rear wall.
  • Bottom of the bar, to be located 39 inches minimum and 41 inches maximum above the floor.

If using a vertical grab bar as a diagonal safety rail, pick a 24-inch grab bar. The recommended installation angle is 45 degrees. The rail should be sloped upwards towards the showerhead. The rail’s lowest point ought to be 9 inches from the tub’s rim.

Angled or vertical grab bars are the best if you are looking for universal grab bars. They can offer stability, comfort, and safety in a wide range of situations.

Entrance Grab Bar Height

Entrance grab bars are vertically oriented grab bars (12, 16, or 18 inches long) offer support when going in or out of a bathroom or wet room. They’re installed at the entry point of a bathroom. The length of the entrance grab bar can be longer if there are multiple users of differing heights.  

Entrance grab bars have standard accessible height guidelines. The vertical entrance grab bar is usually 16 to 18 inches long and installed on the wall opposite the faucet for a bathroom or wet room. Install the vertical entrance grab bars for a shower stall near the shower door jamb.

You can install entrance grab bars to help users get in or out of the shower. The grab bars can offer support at the lower point when standing up or getting seated. The installation height range remains the same. If the intended user has a shower chair and needs support at a lower point when standing or getting seated, it’s best to use a 24-inch grab bar. 

It’s easy to lose footing when entering the bathroom, shower, or wet room. Proper installation of grab bars will increase safety a great deal.
