DIY vs. Hire a Contractor
Not every installation is equal. Some are straightforward weekend jobs. Others need a professional.
| Situation | Best Route | Why |
|---|---|---|
| Drywall wall, easy stud access | DIY | Stud finder + drill, straightforward job |
| Tile shower wall | Hire a pro | Drilling tile wrong cracks it and leaks |
| No visible studs, unsure of wall type | Hire a pro | Wrong anchors in wrong walls fail |
| Multiple bars + full bathroom mod | Hire CAPS contractor | Placement expertise + insurance billing help |
Tools You Need
A standard stud-mounted installation on drywall needs these tools:
- Stud finder (magnetic or electronic)
- Drill with 3/16-inch pilot bit
- Level (a 4-inch torpedo level works fine)
- Pencil for marking
- Phillips head screwdriver
- #10 screws, 3 inches long (often included with the bar)
- Toggle anchors or expansion anchors rated 250 lbs (for non-stud holes)
For tile walls, add a tile drill bit and painter's tape to prevent cracking. Tiled showers are the one case where hiring a contractor almost always makes sense.
Step-by-Step DIY Installation
- 1
Find the studs
Run a stud finder along the wall at the height you plan to mount the bar. Mark each stud edge with a pencil. Studs are typically 16 inches apart. Verify by tapping: a solid sound means stud, hollow means drywall only.
- 2
Mark your bar position
Hold the bar against the wall at the target height. Use a level to make sure it is straight. Mark the mounting hole locations with a pencil. Aim to have at least one hole land on a stud.
- 3
Drill pilot holes
For stud holes: drill a 3/16-inch pilot hole straight in. For non-stud holes: drill to the size specified on your toggle anchor packaging. Go slow to avoid cracking drywall paper.
- 4
Install the mounting flange
Thread your screws through the mounting flange. For stud holes, drive the 3-inch screws straight in. For non-stud holes, insert the toggle anchor first, then thread the screw through the flange into the anchor.
- 5
Attach the grab bar
Slide or snap the bar onto the flanges per the manufacturer instructions. Some bars thread on, others click in place. Tighten any set screws with an Allen wrench.
- 6
Test with full body weight
Grip the bar with both hands and pull down hard. Apply at least 250 pounds of force if possible, or have a heavier person test it. A properly mounted bar will not flex or shift at all.
- 7
Check it monthly
Grab bars in wet environments can loosen over time. A quick pull test once a month takes 5 seconds and confirms the bar is still solid.
Where to Place Grab Bars
Beside the toilet
Mount a horizontal bar on the dominant-hand wall. Position the bar 6 to 8 inches in front of the toilet bowl and 33 to 38 inches from the floor. This height lets you grip the bar while seated and push yourself to standing.
In the shower
A horizontal bar at 33 to 36 inches helps you balance while washing. Add a vertical bar at the shower entry, bottom of bar at 39 inches, top at 60 inches, for gripping as you step in and out. Angled bars (135 degrees) let you grip at multiple points during entry.
At the bathtub
A vertical bar on the wall at the faucet end gives you something to hold while stepping over the tub wall. A horizontal bar on the back wall at 33 to 36 inches helps while lowering into the tub.
Code Requirements
ADA standards require grab bars to support a minimum 250-pound load applied in any direction. For residential use, most quality bars are rated 500 pounds, well above the code floor. The ADA also specifies a 1.25-inch to 2-inch outer diameter for the bar itself, which ensures a proper grip for most hand sizes.
Residential installations do not legally require a permit in most jurisdictions unless they involve structural wall changes. Check with your local building department if you are unsure.
Hiring a Contractor
Professional installation runs $150 to $250 per bar in labor (HomeAdvisor national average). A tiled shower bar costs more, expect $200 to $350 with a tile specialist.
When looking for someone, search for an “aging in place contractor” or a CAPS-certified contractor (Certified Aging-in-Place Specialist, a credential from the National Association of Home Builders). CAPS contractors know ADA placement standards and can help with Medicare Advantage billing for eligible modifications.

Frequently Asked Questions
How much does grab bar installation cost?
DIY installation costs $30 to $120 for the bar itself. A professional handyman or contractor charges $150 to $250 in labor per bar. A full bathroom with two or three bars installed professionally runs $300 to $700 total. See our cost guide for a full breakdown.
Do you have to hit a stud when installing a grab bar?
For stud-mounted installation you need at least one screw in a stud. For the remaining screw holes, use toggle anchors or expansion anchors rated for 250 pounds minimum. Some bars like the MOEN SecureMount system use special anchors that grip the tile backer board and do not require a stud at all.
Can grab bars hold 300 pounds?
Yes. Most quality grab bars are rated 500 pounds when properly mounted into studs or blocking. The weak point is almost always the wall attachment, not the bar. A bar screwed only into drywall can fail under 50 pounds. Always mount into studs, blocking, or rated anchors.
What is the best grab bar brand?
MOEN Home Care is the most widely recommended for residential use. It matches bathroom hardware finishes and is rated 500 pounds. Delta and Stander are solid alternatives. For maximum holding power in any wall type, the Wingits system is the professional standard.
