How to Install a Bathroom Grab Bar (With Stud Finder)

By Raised Toilet Seat Staff

Grab bars are one of the most important safety upgrades you can make in any bathroom, especially alongside a raised toilet seat.

This guide shows you how to install a wall-mounted grab bar the right way—anchored into wall studs so it actually supports your weight.


🧰 What You’ll Need

  • A grab bar (ADA-compliant, 16–24 inches long)
  • Stud finder (digital or magnetic)
  • Pencil or masking tape
  • Power drill
  • ⅛” drill bit + screwdriver bit
  • Screws (often included with the bar)
  • Level (optional but helpful)

🧱 Step-by-Step Installation

1. Pick the Right Location

For toilet use:

  • Side wall: 33–36 inches from the floor
  • Back wall: About 6 inches from toilet centerline
  • Avoid putting bars in places where you can’t lean into them

💡 Use masking tape to mock up where your hand naturally goes.


2. Locate Wall Studs

Use your stud finder:

  • Move it slowly across the wall
  • Mark stud edges with a pencil or tape
  • Find at least 2 solid studs for the bar’s mounting holes

⚠️ Do NOT mount directly into drywall alone!


3. Mark Mounting Holes

  • Hold the bar against the wall
  • Use a level to check alignment
  • Mark the exact screw hole positions with a pencil

4. Drill Pilot Holes

Use a ⅛” drill bit to create pilot holes where marked.
This prevents splitting and helps align your screws.


5. Attach the Grab Bar

  • Align bar over holes
  • Use provided screws to secure into studs
  • Tighten with screwdriver (not just drill!) for final snug fit

Some models have decorative covers—snap those into place last.


🔒 Double Check: Is It Safe?

  • Pull it with your body weight
  • Wiggle it side to side
  • If it moves at all, remove and try again

🧠 Tips for Extra Security

  • Use lag screws for heavy-duty installations
  • Consider corner bars for dual-wall support
  • Avoid tile if possible (or use a tile drill bit + anchors)

💡 No Studs? Use Grab Bar Mounting Anchors

If you’re installing on tile or drywall with no studs nearby:

  • Get toggle bolt anchors rated for >250 lbs
  • Use a ¾” hole saw to install
  • Always follow manufacturer instructions

⚠️ These are Plan B, not ideal for all situations.
