“We need some bars for the shower so Grandpa has something solid to hold. What does it cost to have them put in properly?”

What you’re paying for

Several bars installed in one visit usually cost less per bar than one bar at a time, because travel and setup are paid only once. Plan the whole bathroom at once.

Studs, blocking, and anchors: what holds the bar

• Into studs. The standard method is screwing the bar’s flanges into wood studs. Studs are usually 16 inches apart, so a bar’s length and position often follow the stud layout.
• Into blocking. During a remodel, an installer can add solid wood blocking between the studs so a bar can go exactly where it’s needed. If the wall is already open, this is the cheapest time to do it.
• Hollow-wall anchors rated for grab bars. Where there’s no stud, some anchors are made and rated specifically for grab bars. Ordinary drywall anchors are not.
• Tile and fiberglass. Drilling tile takes the right bit and some care to avoid cracks. Fiberglass and acrylic tub surrounds often have a gap behind them, so they need solid backing or anchors designed for that situation. Check the surround manufacturer’s instructions before drilling.

Placement heights (ADA figures as a reference)

The 2010 ADA Standards set placement rules for public buildings. Homes don’t have to follow them, but they’re a widely used reference point:

• Height: horizontal grab bars mounted 33–36 inches above the finished floor, measured to the top of the gripping surface, at toilets and in tubs and showers.
• Diameter: round bars 1¼–2 inches in outside diameter.
• Wall clearance: 1½ inches between the bar and the wall.
• Strength: the bar and its mounting rated to hold 250 pounds of force.

In a home, the best height is the one that fits the person using it. A vertical bar at the tub or shower entry, and a horizontal bar on the back wall, are common starting points.

Honest Downsides

• Suction-cup bars are not load-bearing. A suction-cup bar isn’t anchored into the wall’s structure. It can release without warning, especially on textured tile, grout lines, or after a few weeks of humidity. Don’t use one as a grab bar or put body weight on it. At most, it’s a touch point for balance, and it shouldn’t be relied on for that either.
• A towel bar is not a grab bar. Towel bars are held by small screws and light anchors. They are not built to hold a person’s weight.
• Tile repair can surprise you. If a tile cracks while being drilled, matching an older tile can be hard. Ask how the installer handles that before they start.
• Wrong placement is common. A bar in the wrong spot doesn’t get used. Mark the position with tape and have the person who’ll use it try reaching it before anyone drills.

Rule of thumb: the bar is the cheap part. Pay for an installation that goes into studs, blocking, or rated anchors, and install every bar the bathroom needs in one visit.
