Grab Bars for the Shower: Where to Install Them and Which to Buy
The tub and shower are the riskiest spots in the bathroom. A grab bar screwed into a stud is one of the cheapest fixes in your parent's house.

Put one horizontal grab bar on the long back wall of the shower, 33 to 36 inches off the floor, and a second bar at the entrance where your parent steps in and out. Screw them into wall studs or use hardware made for that wall. Suction-cup bars and towel bars aren't built to hold a person's weight. A good stainless steel bar is one of the cheapest safety fixes there is.
The grab bars worth buying
Moen Home Care 24-Inch Stainless Grab Bar
A plain, sturdy 24-inch stainless bar with a thicker 1.5-inch grip. Moen rates it to hold up to 500 pounds, it meets ADA specifications, and its SecureMount flanges let the installer catch a stud even at an angle.
Watch for: The stainless finish is smooth, which can feel slick with soapy hands, so pair it with a bath mat that grips.
Moen Home Care 18-Inch Concealed Screw Grab Bar
At 18 inches it's a good length for a vertical bar where your parent steps over the tub edge. The concealed screws leave the flanges smooth, and like the longer bar it's rated to hold 500 pounds and meets ADA specifications.
Watch for: It's slimmer than the bar above, at 1.25 inches, and its polished finish can feel slick when wet. If your parent has large hands, compare the two before you buy a set.
Drive Medical Adjustable Clamp-On Tub Rail
Clamps onto the side of the bathtub with a hand knob: no tools and no holes in the tile, which makes it a good fit for renters. The handle adjusts from 14.5 to 17 inches high, the clamp width adjusts from 3 to 7 inches to fit most tubs, and Drive Medical rates it for 300 pounds.
Watch for: It only works on a bathtub, not a walk-in shower. Drive Medical says to tighten it carefully on fiberglass tubs, and it's worth checking the knob is still tight every week.
Your mom has a routine. She steps over the edge of the tub, reaches for the towel bar and pulls herself in. It has worked for years, right up until the day the towel bar comes out of the wall, or her wet hand slides off the soap dish she's been using as a handle. It's tempting to wait until after a fall to put in grab bars. You can do it the week before. It's a small job, it costs less than a nice dinner out, and it's one of the few safety changes your parent will use every single day without thinking about it.
Why the shower needs grab bars
More than one in four people 65 and older fall each year, according to the National Institute on Aging. In the bathroom, the riskiest spot is clear. When CDC researchers looked at bathroom injuries treated in emergency rooms, 81% were caused by falls, the highest injury rates were in or around the tub or shower, and rates climbed with age. Their recommendation: grab bars inside and outside the tub or shower, and next to the toilet.
You don't need to wait for a fall. These are the signs your parent is already looking for something to hold:
- They grab the towel bar, soap dish, faucet or shower door to step in or out
- They step over the tub edge very slowly, with a hand flat on the wall
- They sit on the edge of the tub to swing their legs over
- They've started showering less often, or only when someone is home
- They've had a fall or a near miss anywhere in the house this year
Where to put them
Before you buy anything, have your parent stand in the dry shower with their shoes on and walk through the motions: stepping in, turning, reaching for the soap, sitting if they use a chair, stepping out. Put a strip of painter's tape wherever their hand goes. That's your map.
- The long back wall. A horizontal bar, 33 to 36 inches from the floor to the top of the bar. That's the height in the ADA accessibility standards.
- The entrance. A bar right where your parent steps over the tub edge or shower curb, on the wall they face. Mounted vertically, it can be gripped wherever their hand lands while they step.
- Low on the tub wall. If your parent sits down in the tub, a second horizontal bar 8 to 10 inches above the tub rim helps them push up to standing.
- Next to the toilet. If the toilet is close to the tub, plan both at once and hire one installer for the job.
What size and style to buy
Length: 24 inches is the usual choice for the back wall, and 16 to 18 inches works for a vertical bar at the entrance. Diameter: the ADA standard allows 1.25 to 2 inches; most home bars are 1.25 or 1.5 inches. The standard gap between the bar and the wall is 1.5 inches.
Look for a bar that says it complies with ADA specifications. The ADA standard calls for the bar, its mounting and the wall behind it to handle 250 pounds of force. Some are rated far higher; Moen rates several of its Home Care bars to 500 pounds. For a shower, a textured finish (Moen calls it peened) gives wet, soapy hands more grip than smooth chrome.
A bar needs a hard tug every few months. With notifications on, your parent can ask Tiina for that reminder, and when the plan's letter about what it covers arrives, share a photo and hear it in plain words.
Why suction bars and towel bars don't count
A towel bar is built to hold a towel. A soap dish is built to hold soap. Neither is designed or tested to catch a person who's slipping.
Suction-cup grab bars look like a shortcut, and the makers themselves say not to lean on them. Drive Medical's own warning on its suction-cup grab bar: "Grab Bar is to be used as a balance assist only. It is not intended to support body weight." It recommends a permanently mounted grab bar for anyone who needs to bear weight.
If you can't drill, a clamp-on tub rail is the safer no-drill choice for a bathtub. It grips the side of the tub itself instead of the wall.
How to install them, or who to call
A grab bar is only as strong as what's behind it. The screws need to go into wall studs, or into anchors made specifically for grab bars in that kind of wall. Moen's Home Care bars use a SecureMount flange that lets the installer hit a stud at any angle, which helps when the studs aren't where you want the bar.
Drilling through tile takes the right bit and some patience, and a cracked tile or a missed stud defeats the purpose. If you're not comfortable doing it, hire a handyman and show them the painter's tape. Your local Area Agency on Aging, which you can find through the Eldercare Locator at 1-800-677-1116, may know of free or low-cost home repair help for older adults. And if your parent has had a fall or surgery, ask their doctor whether an occupational therapist can look at the bathroom. Deciding where grab bars go is part of their job.
If grab bars are one of several changes on your list, the one home fix at a time sheet in your Survival Guide helps you put them in order. When a bar is in, pull on it hard yourself, in every direction, before your parent ever uses it. Then check it every few months. The rest of the bathroom matters too: a nonskid mat, a night light and a clear path all come from the same playbook in our nine home fixes for fall prevention.
Who pays for grab bars
Usually your parent does. Original Medicare doesn't pay for equipment it considers comfort or convenience, and grab bars are on that list, along with bath seats and raised toilet seats. Some Medicare Advantage plans do cover bathroom safety devices, so call the number on your parent's card and ask.
If you hire it out, ask for one price that covers the bars, the anchors and any tile repair, so nothing surprises you after the holes are drilled. Have the toilet bar and the shower bars done on the same visit, so you pay for one trip instead of two.
If money is tight, ask the Area Agency on Aging about home modification programs, and see what else belongs in the budget in what aging in place really costs.
- Walk your parent through a dry run in the shower and tape every spot their hand goes.
- Buy bars marked ADA compliant: a 24-inch bar for the back wall, 16 to 18 inches for the entrance.
- Choose a textured finish for anywhere hands will be wet and soapy.
- Find the studs, or buy anchors made for grab bars in your wall type.
- Mount the back-wall bar 33 to 36 inches from the floor to the top of the bar.
- Pull hard on every bar before your parent uses it, and recheck it every few months.

The towel bar goes back to holding towels, and the bathroom stops being the room she dreads. The rest of the house stays hers too, with Tiina a tap away for a conversation about the news, a recipe, or the bill she wants explained before she pays it.
