Grab Bar Installation: Where to Put Them and What It Costs

October 20, 2026 · 6 minute read · Carpenter Next Door

Short answer

Put grab bars next to the toilet and on both the inside and outside of the tub or shower. Use the ADA range as a guide, with the top of the bar 33 to 36 inches above the floor, and anchor every bar into studs or solid backing. Typical local labor for two or three bars runs $125 to $325, with you supplying the bars.

Where grab bars help most

The CDC and the National Institute on Aging point to the same places. Next to the toilet. Inside the tub or shower. And outside the tub or shower, where you step in and out. These are the spots where you sit, stand, turn, and step onto a wet floor.

  • Beside the toilet. A bar on the side wall gives you something solid to push on when you stand up.
  • Inside the tub or shower. A bar on the long wall helps you stay steady while you wash. Some people also like a short upright bar at the spot where they step in.
  • Outside the tub or shower. A bar on the wall just outside gives you a handhold as you step out onto the bath mat.
  • Near the front door. The National Institute on Aging suggests a grab bar here too, for balance while you open the door with your keys.

Stand in the bathroom and act out your routine before you pick spots. Where do you reach when you sit down? Where do you reach when you step out of the shower? Those are the places a bar belongs.

How high and how big: the ADA numbers

The 2010 ADA Standards set the rules for grab bars in public places like stores and offices. They do not apply to a private home. Still, they are a useful guide, because they were written for people who need support.

Grab bar numbers from the 2010 ADA Standards
MeasurementWhat the ADA Standards say
HeightTop of the bar 33 to 36 inches above the floor, mounted level
Bar sizeRound bars 1.25 to 2 inches across
Space from the wall1.5 inches between the wall and the bar
StrengthBar and mounts must handle a 250 pound force from above or from the side
Toilet side wallBar at least 42 inches long, starting no more than 12 inches from the back wall
Toilet back wallBar at least 36 inches long

The best height for you may be a little different. Your height, how you move, and whether you use a walker all matter. An occupational therapist can help you choose. Ask your doctor whether a home visit makes sense.

Studs, backing, and why the anchor matters

A grab bar is only as strong as what holds it. A pro finds the studs behind the wall and fastens the bar into them. If there is no stud where you need the bar, the pro can use an anchor made and rated for grab bars, or add solid wood backing if the wall is open.

Tile adds a step. The pro drills through the tile with the right bit so it does not crack, then seals around each screw so water stays out of the wall. A fiberglass tub surround needs care too, and may need a special anchor.

When a bar is up, test it. Grab it the way you would if your foot slipped, and pull. It should feel as solid as the wall itself. If it moves at all, have the pro fix it before they leave.

What grab bar installation costs

Typical local labor for two or three grab bars runs $125 to $325, with anchors included and the bars supplied by you. Most installs take about an hour. These are typical local ranges, not quotes. Your price depends on a few things.

  • Tile walls take longer to drill and seal than painted drywall.
  • A spot with no stud may need a special anchor or added backing.
  • More bars mean more time.
  • Longer bars that span two studs are often easier to mount solidly than short ones.

If you are planning other bathroom changes, ask about them at the same time. A handheld shower and bench typically runs $175 to $425 in labor. A comfort height toilet typically runs $175 to $375. Both need a licensed plumber for the water connection. If getting over the tub wall is the real problem, a walk in shower conversion is a larger job at $4,000 to $9,500 in labor.

Picking the bars

  • Buy bars sold as grab bars, not towel bars or decor.
  • A textured grip is easier to hold with wet or soapy hands.
  • Bars come in common lengths like 18, 24, and 36 inches. Pick lengths that fit the wall and reach the studs.
  • Pick any finish you like. It does not change how safe the bar is.
  • Buy the bars before the pro comes, so the job can be done in one visit.

Before you send a request, gather a few details. The pro will want to know who will use the bars and how tall they are. They will ask whether the walls are tile, fiberglass, or painted drywall, and where you want each bar. They will also ask if anyone uses a walker or wheelchair. Photos of each wall help the pro plan the visit.

Getting your grab bars put in

Grab bars are a small job with a big payoff. See what the work involves and what the pro will ask on the grab bars page. When you are ready, send a request and one vetted local pro will call you back. Homeowners never pay this site.
