Grab Bars
ADA values are the standard benchmark for grab bar recommendations, but a private home is not required to comply with ADA. Adjust placement to the client's height, reach, and transfer pattern; the standard is the starting point, not the prescription.

Field notes
- Grab bars must anchor into blocking or studs, never drywall alone. If blocking location forces a compromise between ideal height and solid anchoring, solid anchoring wins.
- Rated capacity to look for on the product label is 250 pounds minimum; institutional bars are commonly rated higher.
- Standard grab bar diameter is 1.25 to 2 inches with 1.5 inches of clearance from the wall, enough for a power grip without letting a forearm slip through behind the bar.
- Suction-cup bars are repositioning aids at best and should never be recommended for weight-bearing transfers.
- Vertical bars at tub and shower entries assist the step-over moment; document them separately from the horizontal transfer bars.
