A wall-mounted towel holder goes up in six steps: mark level mounting points, drill, insert anchors for drywall, screw the plate or flange to the wall, set the holder on the mounts, then tighten the set screws.
One crooked bar means re-drilling, patching, and a repaint — which is why leveling comes before drilling. Getting a towel holder onto a wall is a twenty-minute job once you know the hole size your hardware expects and the anchoring mistake that strips drywall.
What You Need Before You Mark Anything
Gather hardware and tools first, because the holder’s own instructions decide your hole size.
- Drill with a bit matched to your hardware (5/16 in. for Moen bars) and a smaller pilot bit for studs
- Carpenter’s level or a tape measure off the floor
- Pencil, plus painter’s tape if you’re drilling tile
- Wall anchors sized to your wall type
- Screwdriver and the Allen key or supplied wrench from the box
Most wall-mounted towel bars, rings, and robe hooks follow the same architecture: a mounting plate or flange screws to the wall, and the holder attaches over it. That’s why the plate must be level before the bar goes on.
Step-by-Step: Mounting The Plate And Setting The Bar
Hold the bracket flat against the finished wall, level it, mark your holes, then work outward. Drywall patches and paint touch-ups after the fact are far more work than marking carefully once.
- Dry-fit the towel bar against the wall and hold it level. Mark the location lightly in pencil.
- Measure the distance between post centers using the table in your instructions, then mark the screw-hole or anchor locations.
- Insert anchors if you’re not drilling into studs, or if your wall type requires them.
- Fasten the mounting plates or flanges with the supplied screws.
- Slide the towel bar or holder onto the mounts and tighten the set screws with the supplied wrench or Allen key.
Turn wall anchors clockwise so they bore into the drywall like a drill bit. Pushing or hammering them tears the paper face and the anchor never holds. It’s seated correctly when the flange sits flush against the wall and stops turning.
Emtek’s towel bar instructions use the same set-screw approach to lock the bar to its posts, so if your box came with a small Allen key, that’s what it’s for — snug it down, don’t crank it, or you’ll strip the screw head.
Studs, Drywall, And Tile: What Changes
Drilling into a stud lets you skip anchors entirely — direct screw-in mounting holds on its own. Drywall without a stud needs anchors, and the anchor type must match the wall.
| Wall Type | Anchoring Method | Watch For |
|---|---|---|
| Wood stud | Direct screw, no anchor | Pilot hole first to avoid splitting |
| Drywall (no stud) | Self-boring wall anchors | Turn clockwise, never push |
| Tile over backer | Masonry bit, anchors rated for tile | Tape the spot to stop bit wander |
| Hollow-core door | Toggler-style anchor | Weight limit is much lower |
| Plaster | Longer anchors | Plaster crumbles; drill slow |
| Stud + drywall edge | One screw in stud, one anchor | Keep the plate level across both |
| Concrete or block | Masonry anchors | Hammer drill required |

Getting It Level And Keeping It There
Level the bar before the final tightening — set screws lock the position, so there’s no adjusting once they’re snug. A carpenter’s level across the bar is the fastest check, and measuring from the floor up to each end catches sag a short level can miss.
Most first-time installs fail for one of three reasons. Hole spacing measured from the bar instead of the post centers leaves the plates too far apart. Over-tightened set screws strip and the bar spins. And anchors pushed rather than twisted never grip, so the assembly pulls out the first time someone yanks a wet towel off it.
Full manufacturer guidance is worth reading before you drill, and Moen’s towel bar installation instructions spell out the hole sizing and mounting sequence step by step.
FAQs
Do I need wall anchors for a towel holder?
Only if you’re not screwing into a stud. Direct screw-in mounting into a wood stud holds without anchors. Drywall with no stud needs anchors, because screws alone will pull free under the weight of a wet towel. Match the anchor to your wall type and follow the hardware’s instructions.
How do I keep a towel bar from sagging?
Level it before you tighten the set screws, since those lock the position. Measure from the floor to each end of the bar for a longer check than a short level gives. Also confirm your anchors are rated for the load — an undersized anchor in drywall is the most common cause of a drooping bar.
Can I install a towel holder on tile?
Yes, but the wall behind the tile matters. Use a masonry bit, put painter’s tape over the drill spot so the bit doesn’t wander, and pick anchors rated for tile installations. Avoid drilling into grout lines, which are weaker than the tile face and prone to cracking.
