The trick to a sturdy, straight install is preparation: pre-assemble the bar, mark the bracket centers with a level, and anchor into a wall stud when you can. A wobbly bar is almost always the result of skipped anchors, mismatched spacing, or set screws that were never tightened after the bar was seated. If you’re weighing bar sizes before you start, our roundup of the best 32-inch towel bars can help you pick the right fit for the space.
What You’ll Need
Most towel bars ship with the essential hardware, but you’ll want a few tools on hand before you begin.
- Drill with the correct bit for your wall type
- Level (a 2-foot level works well)
- Pencil and painter’s tape
- Stud finder (optional, but recommended)
- Allen wrench or screwdriver, typically included
The Installation Steps
Follow these steps in order, and the whole job should take about half an hour. The key is to measure twice and drill once.
1. Pre-Assemble and Mark the Wall
Manufacturer instructions from Moen and Pottery Barn both recommend assembling the bar and posts first. Lay the assembled bar against the wall in your desired spot, hold it level, and mark the center of each mounting bracket with a pencil. Lowes’ guide suggests a cleaner trick: mark the distance between the bracket centers on a strip of painter’s tape stuck to the edge of your level, then transfer those marks to the wall.
2. Drill and Install Anchors
Hold the level against your marks to confirm they’re even, then drill pilot holes. If you’ve located a wall stud behind a bracket, skip the anchor and drive the screw straight into the stud. On drywall without a stud, insert the included wall anchors—tap them in gently, then drive the mounting screws. Solid tile calls for a tile bit and proper tile anchors. If you’re mounting to drywall, never skip the anchors; screws alone won’t hold the weight of wet towels.
3. Fasten the Brackets
Install the mounting plates with the screws you’ve prepared. Before you tighten them fully, hold the bar’s posts against the plates to confirm everything lines up. Once aligned, tighten the screws completely.
4. Attach the Bar and Tighten Set Screws
Slide the bar and posts onto the mounting plates. Most designs use small set screws at the bottom of each post—loosen them before sliding the posts on, then tighten them with the included Allen wrench once the bar is seated. Waterworks’ guidance notes that the set screws should be loosened, not removed, before installation. A final check: give the bar a gentle tug to confirm it’s secure.
What About Adhesive Mounting?
Adhesive mounting is an option, but it has strict limits. A Home Depot adjustable towel bar manual states that adhesive is only for perfectly smooth, non-porous surfaces like glass, tile, or finished metal. For drywall, plaster, or wood, screw mounting is the recommended route. If you use adhesive, don’t hang anything on the bar for at least 24 hours to let the bond set.
Adhesive systems work best on tile in a guest bath where a stud isn’t conveniently located, but for everyday family use, a screwed-in bar is far more reliable.
Common Mistakes To Avoid
A wobbly towel bar is almost always traceable to one of these four errors. Knowing them in advance keeps you from making them.
- Skipping the level. A bar that’s off by a quarter-inch is obvious every time you look at it.
- Mismatched bracket spacing. The distance between bracket centers must match the bar’s actual length or its template. Measure the bar, not your guess.
- No anchors on drywall. Screws alone in drywall will eventually pull free under the weight of wet towels.
- Forgetting the set screws. The bar will slide or rattle if the set screws aren’t tightened after the posts are seated.
