Short answer: the ADA standard of 33 to 36 inches above the finished floor is a legal requirement for commercial buildings. In a private home it is only a guideline. Residential consumers should mount grab bars at the height that suits their own physical height, reach, and functional needs, and a Certified Aging-in-Place Specialist can help determine what that is.
Where the 33 to 36 inch figure comes from
The Americans with Disabilities Act (ADA) Standards for Accessible Design set grab bar height at 33 to 36 inches, measured to the top of the gripping surface, for toilets, showers, and tubs in public accommodations and commercial facilities. The range is a compromise that works for a broad population: roughly hip to wrist height for a standing adult, and shoulder height for someone seated. In a commercial restroom, a hotel bathroom, or a healthcare facility, that range is not optional.
At home, the person matters more than the code
The ADA does not apply to private residences. That is a good thing, because the person using a bar at home is a specific individual, not an average. A 5-foot-tall woman recovering from a hip replacement and a 6-foot-3 man with limited shoulder mobility need bars in different places. Mount the bar where it serves the user:
- Physical height: shorter users are often better served below 33 inches; taller users above 36.
- Reach: someone with restricted shoulder or arm movement needs the bar within a comfortable range of motion, which may be lower or closer than the standard.
- Function: a bar used to push up from a seat sits lower than one used to steady yourself while standing. A bar used to step over a tub rim is often best mounted vertically so the hand can find its own height.
- Vertical bars at a tub or shower entry: commonly span about 32 to 48 inches from the floor.
- Angled bars in a shower: low end near seated shoulder height, high end near standing hip height, so one bar serves both positions.
Consult a Certified Aging-in-Place Specialist
For a home installation, the best money you can spend is an hour with a Certified Aging-in-Place Specialist (CAPS). CAPS is a designation from the National Association of Home Builders held by contractors, occupational therapists, and designers who are trained to assess an individual's mobility and specify grab bar locations, heights, and orientations for that person. Many will also confirm what is behind your walls and recommend mounting hardware. An occupational therapist or physical therapist can provide the same assessment, especially after a hospital stay.
Measure from the finished floor
Whatever height you settle on, measure from the surface the person actually stands on: the finished floor, or the tub floor inside a tub, not the subfloor or the tub rim. If you are installing before flooring or tile goes in, add the thickness of the finished surface.
Test the height before you drill
Hold the bar against the wall with painter's tape and have the person who will use it reach for it, both standing and seated, in the motions they actually make: sitting down, standing up, stepping in, turning around. Adjust until it feels natural and gives leverage. Then find the studs and install. Our spec sheets and install videos show the process step by step.
