A wobbly toilet paper holder is one of those small annoyances that's surprisingly easy to fix yourself. In most cases, the wall plugs have worked loose or the screws have stripped, and you can have everything solid again in under an hour with basic tools and a trip to your local hardware store.
Why Toilet Paper Holders Come Loose on Tile
Tiled walls are hard and non-porous, which means the fixings have to work harder than on a plasterboard or timber wall. The most common causes of a wobbly holder are:
- Worn-out wall plugs – The plastic plugs expand when a screw is driven in, but over time they can spin or pull out of the hole.
- Stripped screw holes – If the original holes were drilled slightly too large, the plugs never gripped properly.
- Cracked tile around the fixing – Vibration or overtightening can cause hairline cracks, reducing grip.
- Inadequate original installation – Sometimes builders use plugs that are too small for the load.
Tools and Materials You'll Need
- Cordless drill with a tile/masonry drill bit (typically 6 mm or 8 mm — check your plug size)
- Screwdriver (flathead or Phillips, matching your screws)
- Replacement wall plugs (nylon, sized for tile and the wall substrate behind it)
- Stainless steel screws (important in a wet bathroom environment to prevent rust)
- Tile adhesive or epoxy filler (if holes are oversized)
- Masking tape
- Safety glasses
- Optional: two-part epoxy anchoring adhesive (e.g. from Sika or similar)
Step-by-Step: Re-Anchoring the Holder
1. Remove the Holder
Unscrew the holder from the wall and set it aside. If the screws spin without gripping, use pliers to hold the plug while you back the screw out, or carefully lever the plug free with a small flathead screwdriver.
2. Assess the Existing Holes
Check whether the holes are the right size, whether the tile is cracked, and what's behind the tile (plasterboard, fibre cement sheet, or masonry/concrete). This matters because you need the right plug for the substrate.
- Plasterboard behind tile – Use a longer plug that reaches through the tile and grips the board.
- Fibre cement (e.g. James Hardie sheet) – A standard nylon plug usually works well.
- Masonry or concrete – A masonry plug is ideal; consider an epoxy anchor for extra strength.
3. Prepare the Holes
If the holes are only slightly worn, you may be able to go up one plug size (e.g. from 6 mm to 8 mm). Apply masking tape over the tile before drilling — this stops the bit from skating across the glazed surface and helps prevent chipping.
Drill slowly on a low speed with no hammer action until you're through the tile, then switch to hammer mode if you need to go deeper into masonry. Keep the drill cool by pausing regularly.
If the holes are badly oversized, fill them with a two-part epoxy filler or tile adhesive, let it cure fully (check the product instructions), then re-drill once set.
4. Insert New Wall Plugs
Tap the new nylon plugs in flush with the tile surface. They should sit snugly — if they spin freely, the hole is still too large and you'll need to use epoxy anchoring adhesive instead. Mix and inject the adhesive into the hole, insert the plug, and allow it to cure before driving the screw.
5. Reattach the Holder
Drive the screws in firmly but don't overtighten — excessive torque can crack the tile. The holder should feel completely solid with no movement. If your holder has a cover plate, snap or screw it back into place.
6. Seal Around the Fixings (Optional but Recommended)
In a wet bathroom, a small bead of neutral-cure silicone around each screw head helps keep moisture out of the wall cavity. This is good practice in NZ bathrooms, which must meet the moisture management requirements of NZ Building Code clause E3 (Internal Moisture — note that E3 applies to the design and construction of wet areas; for a minor repair like this, the practical concern is simply keeping moisture out of the wall cavity. Use a sanitary-grade silicone suitable for wet areas.
Choosing the Right Products
| Situation | Recommended Fix |
|---|---|
| Slightly worn hole, correct size | Larger nylon plug + stainless screw |
| Badly oversized hole | Two-part epoxy filler, re-drill when cured |
| Hollow plasterboard behind tile | Longer plug spanning tile + board |
| Masonry/concrete wall | Masonry plug or epoxy anchor adhesive |
You'll find a good range of plugs, masonry bits, and epoxy anchors at Bunnings, Mitre 10, or PlaceMakers.
A Note on Tile Cracking
If you notice the tile is cracked around the fixing point, be careful — drilling into a cracked tile can cause it to shatter. In this situation, it's worth getting a tiler to assess whether the tile needs replacing before you re-fix the holder. Cracked tiles in wet areas can also allow water ingress behind the wall lining, which is a bigger problem down the track.
When to Call a Professional
This is a straightforward DIY job for most homeowners, but call a qualified handyperson or tiler if:
- The tile is cracked and needs replacing before re-fixing.
- You're unsure what's behind the tile (e.g. you suspect pipes or cables in the wall).
- Multiple tiles are loose or the wall lining feels soft or damp — this could indicate a moisture problem that needs professional assessment.
- You're not confident drilling into tile without causing damage.
Important: If you suspect there are electrical cables or plumbing pipes behind the wall, do not drill until you've confirmed their location. Electrical work in New Zealand is restricted work under the Electricity Act and must be carried out by a registered electrician — see the Electrical Workers Registration Board for more information. Similarly, any plumbing work must be done by a licensed plumber registered with the Plumbers, Gasfitters and Drainlayers Board.
