Where Should Grab Bars Be Installed in a Bathroom?

A grab bar is most useful when it's within reach for the movement you're making — getting out of the tub, sitting down on or standing up from the toilet, or moving around a wet floor. This guide covers three places federal fall-prevention guidance identifies for grab bars: inside the tub or shower, just outside it, and beside the toilet. It also explains what the published accessibility standard says about height.

Inside the shower or tub

A bar on the wall you face while showering gives you something to hold while standing, and a bar within reach of a shower chair can be useful while seated. Whether a vertical, horizontal or angled bar suits the person — and at what height — depends on who is using it and how they move. An occupational therapist can assess the bathroom and recommend placement for the individual.

Just outside the tub

A CDC analysis of nonfatal bathroom injuries found that bathing, showering and getting out of the tub or shower were the most hazardous activities studied, while only about 2% of injuries happened while getting into the tub or shower. Public-health guidance recommends grab bars outside the tub as well as inside it. A vertical bar just outside the tub, at a height the person can grip comfortably while stepping over, provides a handhold during that step. If stepping over the wall is the real problem, a transfer bench may solve it more directly than a grab bar alone.

Beside the toilet

A horizontal or angled bar mounted beside the toilet gives you something to push against while sitting down and standing up — a movement that happens many times a day. The right position depends on the person, the bathroom layout and how the bar will be used. Accessibility standards for public restrooms provide for bars on both the side wall and the rear wall rather than treating one position as universally better. At home, an occupational therapist can help determine placement for the individual.

General height guidelines

• The 2010 ADA Standards place horizontal grab bars in covered toilet and bathing facilities 33 to 36 inches above the finished floor, measured to the top of the gripping surface. Separate provisions apply to children's toilets and to the lower back-wall bar at a bathtub.
• Those ADA dimensions are accessibility requirements for covered facilities, not a universal rule for an ordinary private home. They can be useful as a reference point when planning residential placement.
• Vertical bars do not have a single standard residential height. Placement should fit the person using the bar and the movement for which it is intended.
• The exact right height is the one that matches how the specific person actually reaches — testing with painter's tape before drilling is a low-cost way to confirm placement

What the bar is fixed to

A grab bar is only as strong as what it's screwed into. For a bar meant to take real body weight, that means wall studs, solid blocking, or a mounting system the manufacturer specifies for that particular bar — not ordinary drywall anchors. Mounting requirements vary by product, so read the instructions for the bar you actually buy. If you're not confident locating studs or blocking, or drilling into tile, this is worth hiring a professional for rather than guessing.
