ADA Bathroom Dimensions: A Practical Cheat Sheet

You do not need to memorize the ADA Standards to build a more accessible bathroom — but a few core numbers matter.

Doorway

• Minimum clear opening: 32 inches (95 percent of wheelchairs fit).
• Recommended: 34–36 inches for caregivers + walkers.
• Swing direction matters — outward swings preserve interior floor space.

Turning radius

• Wheelchair: 60-inch (5-foot) clear circle, ideally beside the toilet.
• Walker: 36-inch circle is workable in small bathrooms.

Grab bar zones

• Beside toilet: vertical bar 28–32 inches above floor, horizontal at 33–36 inches.
• Tub: vertical at the entry, horizontal along the long wall, plus a control-end bar.
