What You Need to Do Before You Start
Replacing a toilet paper holder is a straightforward task that takes about 30 minutes and requires only basic tools you likely already own. The job breaks into three steps: remove the old holder, patch the wall if needed, and install the new one. Most holders mount to the wall with two screws, though some older models may be bolted to the tank or pedestal.
Before you begin, turn off the water supply to the toilet by turning the valve on the line behind the tank clockwise. This prevents accidental spraying if you bump the tank while working. Gather your tools: a screwdriver (usually Phillips head, but check your holder first), a level, a drill with bits if you need new holes, spackling compound and a putty knife if the old holes don't line up with the new holder, and sandpaper if you need to smooth the wall afterward.
Measure the distance from the floor to where the old holder sits—typically 26 inches from the floor to the center of the roll is standard, though some people prefer 24 to 28 inches depending on how they sit. Write this number down so you install the new holder at the same height.
Key Takeaways
- Turn off the water supply before you start work, even though you are not touching the plumbing itself.
- Most holders mount with two screws into wall studs or drywall anchors; check what fasteners came with your new holder before removing the old one.
- If the new holder's screw holes do not line up with the old ones, fill the old holes with spackling compound and drill new ones at the correct height.
- Mount the holder 26 inches from the floor to the center of the roll, or match the height of your old holder if you prefer a different position.
- Test the holder by pulling down firmly on the roll before you call the job done—it should not move or creak.
Removing the Old Holder
Look at the back of your current holder to see how it fastens. Most wall-mounted holders have two screws visible on the face or hidden under a decorative cap. If there is a cap, pry it gently with a flathead screwdriver or your fingernail to expose the screws underneath. If the holder is mounted on the tank itself, you will see bolts on the underside of the tank—these require a wrench or socket set, not a screwdriver.
For wall-mounted holders, unscrew both fasteners by turning them counterclockwise. Keep the screws in a small container so you do not lose them—you may reuse them if the new holder accepts the same size. Gently pull the holder away from the wall. If it is stuck, do not force it; spray a small amount of penetrating oil (like WD-40) around the edges and wait five minutes, then try again.
Once the holder is off, inspect the wall. If the screw holes are clean and the wall is not damaged, you can reuse them. If the holes are stripped, enlarged, or the new holder's holes do not line up, you will need to fill them. Wipe away any dust or debris from the wall with a dry cloth.
Filling Old Holes and Preparing the Wall
If the new holder's mounting holes line up exactly with the old ones, skip this section. If they do not, you need to fill the old holes so they are not visible and the wall is smooth enough for the new fasteners.
Use a putty knife to press spackling compound into each old hole. Overfill slightly, then scrape the excess flat with the edge of the knife, leaving the surface level with the surrounding wall. Let the compound dry according to the package directions—most brands dry in 1 to 2 hours. Sand the dried compound lightly with fine-grit sandpaper (220 grit or higher) until it is smooth and flush with the wall. Wipe away the dust with a damp cloth and let it dry completely.
If you are drilling new holes, use a level to mark the exact position of both screw holes on the wall. Hold the new holder against the wall at the correct height, place the level on top, and adjust until the bubble is centered. Mark the screw holes with a pencil, then remove the holder. Drill pilot holes at the marks using a drill bit slightly smaller than the screws or anchors that came with your new holder. If you are drilling into drywall, use drywall anchors (the plastic sleeves that expand behind the wall) unless you know the holes line up with wall studs.
Installing the New Holder
Position the new holder on the wall, aligning the mounting holes with the screw holes or pilot holes you prepared. If the holder has a decorative escutcheon (the plate that covers the wall), slide it onto the mounting rod first, then position the rod against the wall. Insert the screws through the holder into the wall and turn them clockwise by hand first to make sure they are threading correctly and not cross-threading.
Once both screws are hand-tight, use your screwdriver to tighten them fully. Do not over-tighten—stop when you feel firm resistance. Over-tightening can crack the holder or strip the screw holes. If the holder has a decorative cap, snap or screw it into place to cover the fasteners.
Place the toilet paper roll onto the holder and check that it spins freely and the holder does not move. Pull down firmly on the roll with your hand—it should not shift, creak, or flex. If it moves, remove the roll and tighten the screws another quarter turn, then test again.
Choosing Between Screw and Bolt Mounting
Wall-mounted holders with screws are the most common and easiest to install. They work on drywall, tile, and wood. Tank-mounted holders bolt to the side of the toilet tank and require no wall work, but they can be awkward to reach and may interfere with tank cleaning. Over-the-tank holders rest on top of the tank and need no fasteners at all, but they take up space and can tip if bumped.
If you are replacing an old tank-mounted holder with a new wall-mounted one, you will need to fill the bolt holes on the tank with epoxy or silicone caulk to prevent leaks. If you are switching from wall-mounted to tank-mounted, you can leave the old screw holes in the wall and fill them as described above, or cover them with a small picture or shelf.
Common Mistakes to Avoid
The most common error is mounting the holder too high or too low. Always measure from the floor to the center of the roll and compare it to your old holder or the standard 26-inch height. Mounting it too high makes it hard to reach; too low and it may hit your leg or the wall behind the toilet.
Another frequent mistake is drilling into the wrong spot. Always use a level and mark both holes before drilling. If you drill one hole and it is off-center, stop and fill it before drilling the second one—it is easier to fix one mistake than two.
Do not over-tighten the screws. Plastic holders can crack, and metal ones can strip the screw holes. Tighten until snug, then stop. If the holder still moves after you have tightened the screws, the wall anchors may be too small—remove the holder and use larger anchors rated for more weight.
Finally, do not skip the water shut-off step, even though you are not touching the plumbing. If you accidentally bump the fill valve or supply line while working, you want the water already off so it does not spray everywhere.
Frequently Asked Questions
What if the wall is tile instead of drywall?
Drill through the tile with a carbide or diamond-tipped bit designed for tile, then continue into the wall behind it. Use plastic anchors rated for the weight of your holder. If you hit a stud behind the tile, use a regular wood screw instead. Tile drilling is slower and requires a steady hand, but the process is otherwise the same.
Can I use the old screw holes if they are slightly enlarged?
If the holes are only a little loose, try larger plastic anchors designed to fit the enlarged hole. If the holes are too damaged, fill them with spackling compound and drill new ones nearby. Do not try to force screws into badly stripped holes—they will not hold the holder securely.
What if my new holder is heavier than the old one?
Check the weight rating on the packaging and make sure your wall anchors are rated for that weight. If you are mounting into drywall, use heavy-duty anchors rated for at least 25 pounds. If the holder is very heavy, drill into wall studs if possible—studs are behind the drywall at 16-inch intervals and can hold much more weight than anchors alone.
Do I need to caulk around the holder after installation?
Caulking is optional and mostly for appearance. If there are gaps between the holder and the wall, you can run a bead of paintable caulk around the edges for a finished look. Let it dry and paint over it if needed. This is not necessary for function, only for aesthetics.
What if the holder spins or moves after I have tightened the screws?
Remove the holder and check that the wall anchors are fully seated in the wall. If they are loose, remove them and replace them with larger anchors. If you are screwing directly into studs and the holder still moves, the screws may be too short—use longer screws rated for your holder's weight.
