Last Updated: September 24, 2026
The ideal place for a grab bar is not always where a wall stud happens to be. Studs are usually spaced 16 or 24 inches apart, and the spot an older adult needs to hold, such as right beside the toilet or at the shower entrance, often falls between them. The good news is that grab bars can be installed safely without studs, as long as the right anchors are used and installed correctly. This guide explains the options, the steps and the mistakes to avoid.
Quick answer: Our top pick in 2026 is the Both ends into studs — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
Why ordinary anchors are not enough
Grab bars need to withstand sudden, heavy loads when someone slips or pulls up. Common accessibility guidance uses a 250-pound force as the design benchmark. Standard plastic drywall anchors, expansion plugs and self-drilling anchors are not designed for that, and they can pull out of drywall with a fraction of the force. Using them for a grab bar can create a false sense of security.
Options for installing without studs
Heavy-duty hollow-wall anchors made for grab bars
Several anchor systems are specifically designed and tested for grab bars in hollow walls. Typically, a wing or toggle mechanism opens behind the drywall or tile and spreads the load over a large area. Follow the manufacturer’s rated wall types exactly.
Toggle bolts
Heavy-duty metal toggle bolts can hold substantial loads in drywall, but ratings vary greatly. Only use toggles if the grab bar manufacturer or anchor maker explicitly rates them for grab bar use.
Adding blocking
If the wall is being opened, for example during a remodel, adding horizontal wood blocking between studs gives a solid backing anywhere along the wall. This is the gold standard.
Mounting to one stud plus an anchor
If one end of the bar can reach a stud, fixing that end to the stud and the other end with a rated anchor is often a practical compromise.
Diagonal placement
Angling a bar diagonally can sometimes let both ends reach studs, and diagonal bars are comfortable for pulling up.
Options compared
| Method | Strength | Difficulty | Typical cost |
|---|---|---|---|
| Both ends into studs | Highest | Easy to moderate | Bar only, $20 to $70 |
| Wood blocking behind wall | Highest | Hard (wall must be open) | $100 to $500 with repairs |
| Rated grab-bar anchors | High, per rating | Moderate | $15 to $40 per set |
| One stud plus rated anchor | High | Moderate | $10 to $25 extra |
| Standard plastic anchors | Not suitable | Easy | Do not use |
Step-by-step with rated anchors
1. Plan placement
Decide the location with the user. Common heights for horizontal bars are about 33 to 36 inches above the floor. Mark the flange positions with a level.
2. Check the wall
Use a stud finder to confirm what is behind the wall and to avoid pipes and wiring. Check wall thickness; anchors are rated for particular thicknesses of drywall or tile plus backer board.
3. Drill correctly
For tile, use a carbide or diamond bit, start slowly with no hammer action, and keep the bit cool. Drill the hole size the anchor requires, no larger.
4. Install anchors
Insert the anchor and deploy the wing or toggle per instructions. Many systems have a visual confirmation that the anchor is seated.
5. Attach the bar
Seal the holes with silicone to keep water out, then fasten the flanges with the supplied screws. Tighten firmly but do not over-tighten, which can crack tile.
6. Test
Pull and push firmly in all directions. There should be no movement. Re-check after a week, and periodically after that.
When to call a professional
If the wall type is unclear (plaster and lath, fiberglass surround, very thick tile), if plumbing is nearby, or if the user will depend heavily on the bar, a professional installer is worthwhile. Many handypersons and aging-in-place specialists install grab bars for around $75 to $200 per bar.
FAQ
Can I install a grab bar on a fiberglass shower surround?
Often yes, with anchors rated for fiberglass or by reaching studs behind. The surround alone is not strong enough, and some manufacturers make specific kits for this.
Are suction grab bars an alternative?
Suction bars do not need studs, but most are designed for balance only, not full weight-bearing. For support, use a properly anchored bar.
Bottom line
You can install a grab bar without studs safely by using anchors specifically rated for grab bars, or by adding blocking during a remodel. Never rely on standard plastic anchors. Plan placement, drill carefully, seal holes, and test the bar before use.
