The single most effective thing you can do to make a bathroom safer for an aging parent — or yourself — is install a grab bar. Bathrooms are the most dangerous room in the house for adults over 65, and a properly installed grab bar can be the difference between a confident step out of the tub and a broken hip.
Some grab bars can be a manageable DIY project when you know the wall construction, can fasten into structural backing, and can follow the bar manufacturer's instructions exactly. Unknown backing, tile or cement-board assemblies, waterproofing concerns, or uncertainty about placement are good reasons to use a qualified installer. A CAPS-certified professional or occupational therapist can also help when the user's reach, balance, or transfer pattern should guide placement.
The Moen 8724 24-inch Stainless Grab Bar is one commonly considered option — available on Amazon →. Before buying, verify the current manufacturer specifications, warranty, included hardware, and compatibility with your wall assembly. The bar, fasteners, mounting system, and supporting structure all matter; a product rating by itself does not make an installation safe.
Choosing the Right Grab Bar Before You Install
Installation is only as good as the bar you start with. Here’s what matters:
Material. Look for 18-gauge or thicker stainless steel. Chrome-plated brass is also solid. Avoid lightweight aluminum or any bar that flexes when you squeeze it — it won’t hold under sudden load.
Diameter. The ADA Standards specify a circular grab-bar diameter of 1.25–2 inches for covered accessible facilities. In a private home, also consider the user's hand size, grip strength, and ability to wrap a hand around the bar comfortably.
Length. Match bar length to location. Beside the toilet: 24–36 inches. Along the back wall of a shower: 36 inches. Beside the tub: 18–24 inches.
Structural capacity. The ADA Standards require the bar, fasteners, mounting device, and supporting structure to resist 250 pounds of force at any point for covered accessible installations. A “500 lb” label on the bar is not enough on its own: confirm that the complete installation method is approved for the specific wall assembly.
Finish. Match your bathroom fixtures. Polished chrome, brushed nickel, and oil-rubbed bronze are all widely available. A textured (knurled) grip surface is worth considering for seniors with reduced hand strength.

How to Install a Grab Bar: Step-by-Step
What You’ll Need
Before you start, gather: grab bar with included mounting hardware, stud finder, cordless drill, level and pencil, tape measure, Phillips head screwdriver, tile drill bit (diamond-tip or carbide, if installing through ceramic tile), and bathroom-grade silicone caulk.
For stud or structural-backing mounting: use the fasteners specified by the grab-bar manufacturer.
For a location without structural backing: use only a manufacturer-engineered mounting system explicitly approved for that grab bar and the exact wall assembly. If the product instructions do not approve the condition you have, use a qualified installer.
Before you drill
- Match: Match the bar and approved mounting system to the exact wall assembly.
- Locate: Confirm structural backing and check for hidden plumbing or electrical hazards.
- Fit: Confirm that the position works for the user’s reach and transfer needs.
- Protect: Follow the manufacturer’s drilling, fastening, sealing, and final-inspection instructions.
Step 1 — Find Your Studs
This is the most important step. Use a stud finder along the wall where you plan to mount the bar. Standard stud spacing is 16 inches on center. Mark each stud location with a pencil.
If structural backing falls where the bar needs to go, follow the manufacturer's fastener, pilot-hole, and embedment instructions for that backing and wall finish.
If there is no structural backing where the bar needs to go, do not substitute generic plastic anchors or generic hollow-wall fasteners. Some manufacturers offer engineered no-stud systems for specific bars and wall assemblies. Use one only when the grab-bar and mounting-system instructions explicitly approve your exact combination; otherwise, have a qualified installer add backing or choose another safe location.
Step 2 — Mark Bar Height
For covered accessible facilities, the ADA Standards place many horizontal grab-bar gripping surfaces 33–36 inches above the finished floor. That is a compliance dimension, not a universal prescription for every private home. Residential placement should fit the person's actual reach and transfer pattern, the fixture layout, available structure, manufacturer instructions, and applicable local requirements.
Use your tape measure and pencil to mark the mounting hole positions. Hold a level across the marks to ensure they’re perfectly even. Then hold the bar in position and ask the user to grab it — verify the height feels natural before you drill.
Step 3 — Drill Pilot Holes
Mounting into drywall with a stud: Use a 5/32" drill bit. If there’s tile, start with a diamond-tip tile bit at slow speed (no percussion mode) until through the tile, then switch to a standard bit for the stud below.
Using an approved engineered mounting system: Follow that system's instructions exactly, including its wall-material, hole-size, clearance, and compatible-bar requirements. Do not adapt generic hollow-wall hardware for a grab bar.
Step 4 — Apply Silicone Sealant
Before mounting, run a thin bead of bathroom-grade silicone caulk around the back perimeter of each mounting flange. This waterproof seal prevents moisture from working its way into the wall — a silent source of mold and structural damage in older bathrooms.
Step 5 — Mount the Bar
Stud mounting: Feed stainless screws through the flange holes into the pilot holes and tighten firmly. Screws should penetrate at least 1 inch — ideally 1.5 inches — into the stud. Snug, not stripped.
Engineered no-stud mounting: Use only the hardware, flange arrangement, and tightening sequence specified by the approved mounting-system manufacturer. If the instructions do not match the wall assembly or bar, stop and use a qualified installer.
Step 6 — Test Before Use
Before anyone depends on the bar, inspect every flange and fastener and check for movement without using the bar as full-body test support. Follow the manufacturer's final-inspection instructions; where the installation condition is uncertain, have a qualified installer verify it.
A correctly installed grab bar should not shift at the wall. If there is any movement, stop using it and have the mounting and supporting structure corrected before anyone relies on it.
Product Reviews
Moen 8724 — 24" Stainless Steel
The Moen 8724 is the grab bar we recommend most. Twenty-four inches of 1.25-inch diameter stainless steel, rated to 500 lbs, with concealed mounting screws that give it the look of a towel bar rather than a medical fixture. The included hardware is stainless — not the cheap zinc-plated screws some competitors include.
What we like: Concealed screw design looks intentional, not institutional. Limited Lifetime Warranty. Good hardware included.
Limitation: Sold individually; order multiple if equipping a full bathroom.

Moen 8736 — 36" Stainless Steel
The longer version of the 8724. Thirty-six inches gives you three mounting flanges and six screws, distributing load across more wall surface. If you can install only one bar in a walk-in shower, make it this one along the back wall.
What we like: Three flanges means more anchor points and more flexibility to hit studs. Accommodates users of different heights.
Limitation: Getting all three flanges level simultaneously takes a bit more patience.
AmazerBath 12" — Brushed Nickel
For smaller spaces or supplementary installs — beside a toilet, or at an angle near a tub entry — the AmazerBath 12" is a solid value choice. The brushed nickel finish is attractive, the steel doesn’t flex, and at around $22 it makes sense to buy several for a multi-location project.
What we like: Anti-slip knurled texture provides grip for soapy hands. Genuine 500 lb rating. Clean aesthetic.
Limitation: Mounting-hole spacing may limit where the bar can align with structural backing. Verify the current manufacturer instructions and approved mounting options before buying.
Vive Grab Bar — 12" Dark Bronze
If your bathroom has oil-rubbed bronze fixtures, the Vive bar is the grab bar to buy. The finish closely matches Moen and Delta oil-rubbed bronze — it looks like it belongs, not like a safety add-on.
What we like: Finish quality is above average. Water-resistant coating. Comes in colors most competitors don’t offer.
Limitation: 440 lb rating is slightly lower than competitors, though well within safe range.
2-Pack 16" Grab Bars
If you’re outfitting multiple locations — toilet, tub, and shower — a 2-pack at 16 inches is the most practical choice. Sixteen inches is a good all-rounder: long enough to be useful, short enough for tight walls.
What we like: Best value per bar for whole-bathroom projects. 500 lb rating. Clean chrome finish.
Limitation: Hardware quality is a step below Moen. Use stainless screws from a hardware store when mounting into studs.

When to Call a Professional
Not every grab bar installation is DIY territory — and being honest about that is part of keeping people safe.
Call a professional if your bathroom walls are solid tile over cement board with no accessible drywall to locate studs. Call a professional if a family member needs multiple bars across multiple rooms and functional placement matters as much as structural soundness. Call a professional if the person using the bar has dementia or significant balance impairment — a CAPS-certified specialist can assess the full home environment.
A CAPS (Certified Aging in Place Specialist) contractor is trained specifically in bathroom safety modifications. Professional grab bar installation typically runs $100–$300 per location including materials — a modest investment compared to the cost of a fall-related hospitalization.
FAQ
What height should grab bars be installed at?
For covered accessible facilities, the ADA Standards place many horizontal grab-bar gripping surfaces 33–36 inches above the finished floor. In a private home, the right location also depends on the person's reach and transfer pattern, fixture layout, structural backing, manufacturer instructions, and local requirements. An occupational therapist can help with functional placement when needs are complex.
Can I install a grab bar without hitting a stud?
Sometimes, but only when the grab-bar manufacturer or an engineered mounting-system manufacturer explicitly approves the bar, fasteners, and exact wall assembly together. Do not use ordinary picture-hanging anchors or assume that an individual anchor's load rating makes the complete installation safe. If the instructions do not cover your wall condition, use a qualified installer.
How many grab bars does a bathroom need?
Most homes benefit from three: one beside the toilet, one along the side wall of the tub or shower, and one at the tub or shower entry. A shower with a bench benefits from a fourth near the seated position.
Can grab bars be installed through tile?
Yes. Use a diamond-tip or carbide tile drill bit at slow speed with no percussion mode. Always seal behind the flange with silicone caulk to prevent water intrusion.
What’s the difference between a grab bar and a towel bar?
Load rating and mounting design. Towel bars hold a pound or two. Grab bars are engineered to hold 250–500 lbs of sudden force. Never substitute a towel bar for a grab bar — it will pull out of the wall.
How long does installation take?
Time varies with the wall finish, backing, bar design, waterproofing details, and whether repairs or added blocking are needed. Do not let a time estimate rush the structural or waterproofing work; a qualified installer can assess the condition before quoting it.
Does insurance cover grab bar installation?
Medicare generally doesn’t cover grab bars as a standalone item, but some Medicare Advantage plans and Medicaid waiver programs do. Your local Area Agency on Aging is the best starting point to find grant programs in your area.
Bottom Line
Grab bars can be a valuable bathroom-safety improvement, but the safe installation is a system: the bar, fasteners, mounting device, supporting structure, wall finish, waterproofing, and placement all have to work together. Follow the exact manufacturer's instructions for the bar and wall assembly. When the structure is unknown or the approved installation method does not match the wall, use a qualified installer.
If your walls are all tile with no clear way to find studs, or you want professional placement guidance, a CAPS contractor is worth the investment. The cost is modest; the peace of mind is not.
