Outsmart the Hidden Set Screw to Remove a Towel Bar
You have decided it is time for a bathroom refresh. That old towel bar must go. The problem is it feels solidly attached to the wall. Most homeowners assume it is simply screwed in. In reality, nearly 70 percent of modern towel bars rely on a tiny, concealed set screw. The manufacturer’s goal is to keep this screw hidden. Just because you cannot see it immediately does not mean it is absent.
Start by looking closely at the end posts. These are the decorative pieces where the bar meets the wall. Check the bottom first. Use a flashlight to examine the underside. Many set screws sit here, almost invisible to the naked eye. If you do not see anything, check the inside edge of the post, facing the bar itself. The screw will be very small, often smaller than a grain of rice.
Find the Right Tool for the Screw
Once you locate the tiny hole, determine the tool you need. This is almost always a small Allen wrench, also known as a hex key. Standard sizes in bathroom hardware are usually metric, with 4mm or 5mm being the most common. Budget brands sometimes use imperial sizes like 5/32 of an inch. If you do not own a full set of Allen keys, pick one up from any hardware store. A mini flathead screwdriver works for some models, but an Allen key provides the best grip.
Insert the tool and turn it counter-clockwise. You do not need to remove the screw entirely. Loosening it by two or three full rotations is usually enough. If the screw feels stripped or spins freely, try a larger size key. Tapping the key lightly with a hammer can help seat it into a worn socket.
After loosening, the bar should move freely. Push upward on the base of the end post. Some models require you to push outward or pull the bar away from the wall simultaneously. The bar will slide off the bracket once the screw no longer holds it in place. Repeat this process for the second end post.
Depress the Locking Tab to Remove a Towel Bar With No Visible Fasteners
Some towel bars do not have a set screw at all. If you have searched thoroughly and found nothing, your bar likely uses a locking tab system. This is a spring-loaded clip inside the post. It holds the post tightly against the wall bracket. Removing the bar requires you to release this clip manually.
Look for a small slot, indentation, or button. It is usually located at the bottom of the end post. Sometimes it sits on the side facing the wall. The slot is often covered by a thin layer of paint or grime, so look closely. A bright flashlight helps reveal the seam.
Release the Spring Mechanism
Take a small flathead screwdriver and insert it into the slot. You will feel a slight resistance. Depress the tab firmly. While holding the tab down, try to manipulate the post. Gently pull the post away from the wall. If it does not release, try pulling at a different angle. The tab only releases the post when pressure is removed from the clip.
You may need an extra set of hands for this step. One person depresses the tab while the other wiggles the post. Once the first post is free, the bar will pivot slightly. Repeat the process on the second post. This method preserves the bracket and the post, allowing you to reuse the hardware if you wish.
Cut Through Adhesive or Mortar for a Clean Removal
Towel bars mounted on tile or stone surfaces rarely use screws. Installers use construction adhesive or thin-set mortar instead. This creates an incredibly strong bond. Pulling the bar off by force can crack the tile or tear the surface of drywall. You need a precision tool to break this grip.
The best tool for this job is an oscillating multitool. These tools vibrate at a high frequency, allowing a thin blade to slide into tight spaces. The original oscillating tool was introduced by Fein in 1967, but modern versions are affordable and easy to find. Fit the tool with a flush-cut or scraper blade.
Score Before You Cut
Before you start the oscillating tool, take a utility knife. Run it around the base of the post where it meets the wall. This cuts through any paint or caulk seal. Skipping this step often leads to peeling paint. The score line ensures a clean edge.
Slide the blade of the oscillating tool between the post base and the wall. Gently press the blade into the adhesive. Let the tool do the work. Do not force it, or you may gouge the wall. Move the blade back and forth along the base until the post separates from the wall.
This process creates dust. Cutting mortar releases crystalline silica into the air. The Occupational Safety and Health Administration (OSHA) classifies respirable crystalline silica as a serious lung hazard. Wear a proper dust mask or respirator while you work. Ventilate the room by opening a window or running a bathroom fan.
Clean the Residual Adhesive
After the bar is removed, you will be left with chunks of adhesive on the wall. Use a plastic putty knife or a scraper to remove the bulk material. For stubborn spots, use a sanding block with coarse grit sandpaper. If the adhesive remains sticky, mineral spirits on a rag can soften it. Always test cleaning solvents on an inconspicuous area first.
If the wall surface is damaged during removal, do not panic. You can repair torn drywall paper or chipped paint. The key is removing the old adhesive completely so the new patch adheres properly.

Extract Stubborn Drywall Anchors Without Tearing Holes
Once the bar itself is down, you face the brackets. These are usually screwed into drywall anchors. Most builders use plastic expansion anchors because wall studs rarely align with the bar ends. You must remove these anchors to have a smooth wall for patching.
Do not just pull the screws out. If you remove the screw, the hollow anchor stays in the wall. Pushing it inward creates a big hole behind the surface. The clever trick is to use the screw itself as a removal tool.
The Reverse Screw Technique
Take one of the screws from the bracket. Thread it back into the plastic anchor by hand. Stop turning once you feel resistance. You only need the screw to grip the anchor, not to expand it further. The tip of the screw should sit inside the anchor without pressing against the back of the drywall.
Place a small piece of cardboard or a scrap of wood against the wall next to the anchor. This protects the paint from damage. Use the claw of a hammer or a pair of needle-nose pliers to grip the head of the screw. Pull straight out toward you. The anchor will slide out of the hole cleanly.
This works because the screw threads bite into the plastic. The anchor does not collapse inward. Instead, it stretches slightly and releases from the drywall. You are left with a small, round hole that is easy to patch. If the anchor crumbles, use tweezers or small pliers to pull the remaining pieces out.
Patch and Paint to Restore Your Wall
After you remove a towel bar and its anchors, you must repair the wall. This final step determines if the project looks professional or sloppy. Fortunately, the holes left by a towel bar are very small. A standard bracket leaves two screw holes per side. You can fill them in minutes.
Start by trimming any frayed drywall paper around the holes. Use a sharp utility knife to cut a clean circle around the opening. Loose paper fibers create bumps under the paint. Cutting them flush gives you a smooth base.
Fill, Sand, and Prime
Apply lightweight spackle or joint compound to the holes. Use a small putty knife to press the compound deep into the hole. Overfill slightly to compensate for shrinkage as it dries. Allow the compound to dry completely. Most lightweight spackles dry in 30 to 60 minutes.
Sand the area with fine-grit sandpaper, around 220 grit. Sand in a circular motion until the patch is completely flush with the surrounding wall. Wipe the dust away with a damp cloth. Do not skip this step. Dust prevents paint from adhering properly.
Prime the patch before painting. Unprimed spackle absorbs paint differently than the surrounding drywall. This creates a noticeable flat spot called flashing. A quick coat of primer seals the patch. Once the primer dries, paint the entire wall from corner to corner. Painting only the patched area leaves a visible edge.
Removing a towel bar is a straightforward job. The cleverness lies in identifying the mounting type quickly. Use the right technique for your specific bar, and you will avoid unnecessary wall damage. A clean removal makes the patching process simple, leaving your wall ready for a fresh new fixture or a clean, minimalist look.
