Can I Screw Into Tile?

Yes, and no shortcut around it. Tile doesn’t grip a screw the way drywall or wood does, so a screw driven straight into the glaze either cracks the tile or spins uselessly in a hole that was never meant to hold anything. Drill the right pilot hole, set an anchor, then the screw. Skip a step and the towel bar comes off the wall inside a year, tile and all.

The Short Answer

Screwing into tile means drilling first, not driving a screw straight in with a screwdriver or drill driver. Carbide-tipped bits handle ceramic. Diamond-tipped bits handle porcelain, glass, and natural stone. Once the hole is through, a plastic or self-drilling anchor sized to the screw goes in, and the screw threads into that, not into bare tile.

We get this question most often from homeowners hanging a towel bar, a mirror, or floating shelves over a backsplash. All three follow the same logic. The tile is the hard, brittle top layer. What actually holds the weight is the anchor and whatever’s behind the tile, stud, backer board, or solid substrate.

Why You Can’t Just Screw Into Tile Without Drilling First

Glazed ceramic and porcelain are fired at high heat into a dense, glass-like surface. A self-tapping screw has nothing to bite. Force it and one of two things happens: the tip skates across the glaze and scratches it, or it catches unevenly and the tile cracks radiating out from the point of pressure. Either way, no thread gets cut.

Compare that to drywall, where the screw carves its own path through paper and gypsum. Tile needs a pre-drilled hole matched to an anchor before a screw does anything useful. That’s the whole difference, and it’s why the drilling step matters more than the screw itself.

Tools You Need to Screw Into Tile

A variable-speed drill, a carbide-tipped masonry bit for ceramic or a diamond-tipped bit for porcelain and glass, painter’s tape, a pencil, a spray bottle of water, safety glasses, and the anchors and screws sized for whatever you’re hanging. A stud finder or wall scanner belongs on that list too, and it’s the tool most tutorials skip.

Diamond bits cost more than carbide, sometimes double. Buy the right one anyway. A carbide bit forced through porcelain burns out fast and takes the tile’s finish with it on the way, which turns a ten dollar bit into a cracked tile and a redo.

How to Screw Into Tile Without Cracking It

Mark the spot with a pencil, then lay a strip of painter’s tape directly over the mark. The tape gives the bit something to grip so it doesn’t skate sideways on the glaze before it bites in. Re-mark the spot on top of the tape.

Run a wall scanner over the area before anything touches the tile. Bathrooms in particular route plumbing and wiring right through the wall cavity at fixture height, exactly where a towel bar or mirror bracket wants to go. Two minutes with a scanner beats explaining to a plumber why there’s a hole in a supply line behind the vanity mirror.

Start the drill at a slight angle, maybe fifteen degrees off vertical, at the lowest speed setting. That angle gives the bit an edge to grab instead of spinning flat against smooth glaze. Once a small dimple forms, straighten the drill to ninety degrees and keep going at low speed with light, steady pressure. Let the bit do the cutting. Pushing harder just generates heat and heat is what cracks tile.

Spray the bit with water every few seconds if the tile is thick or the hole is deep. A dry bit heats up fast, and an overheated carbide or diamond bit dulls quickly and can shatter the glaze on the way out even after doing everything else right.

Once through the tile, you’ll likely hit backer board, drywall, or solid substrate. Some installers switch to a standard bit at that point since tile bits work slower and less efficiently on wood or gypsum than a purpose-built bit does. Not required, just faster.

Tap the anchor in gently with a hammer once the hole’s cleaned of dust. Drive the screw into the anchor, not force it, and stop once it’s snug. Overtightening an anchor in tile can crack the hole outward from the inside, which defeats the whole careful process that got you there.

Which Anchors Work Best When You Screw Into Tile

Plastic wall anchors handle light loads: a towel hook, a small frame, a soap dish bracket. Self-drilling tile anchors work for mid-weight items and skip the separate pilot-hole-then-hammer-in step some plastic anchors need. Toggle anchors or heavier-duty options come into play for anything with real weight behind it, a grab bar, a full-length mirror, floating shelves meant to hold more than a few knick-knacks.

If a stud sits behind the spot, screw straight into that once the pilot hole clears the tile. A stud beats any anchor for pure holding strength every time. That’s worth checking for before assuming an anchor is the only option, especially over a backsplash where studs run sixteen inches apart same as any other wall.

Ceramic, Porcelain, and Natural Stone: Screwing Into Tile Changes by Material

Ceramic is the forgiving one. Carbide-tipped bits cut through it without much drama, and it’s the tile most towel bars and hooks go into. Porcelain runs harder and denser, fired at a higher temperature, which is exactly why the same carbide bit that sails through ceramic will burn out or wander on porcelain. Diamond-tipped bits are built for that density.

Glass tile needs its own bit entirely, ground specifically for glass, and a gentler hand since it’s more prone to shattering than either ceramic or porcelain. Natural stone, marble, travertine, slate, generally takes a diamond bit as well, though some softer stones will accept carbide if you’re patient and keep the speed low.

Check the type before buying a single bit. Guessing wrong means a second trip to the hardware store and a tile with a chip where a clean hole should be.

Drilling Through Grout Instead of Tile

Grout is softer than the tile around it, and a hole through grout is far more forgiving if something goes slightly wrong. If the mounting spot has any flexibility, a bracket with adjustable hole spacing, a hook that doesn’t need to sit exactly centred, putting the hole in a grout line instead of the tile face is worth considering. Any small chip or ragged edge in grout gets covered with fresh grout later. The same mistake on the tile face stays visible.

Screwing Into Tile in a Wet Area Gets Complicated

A backsplash or a dry bathroom wall is one thing. A shower surround is another. Behind that tile, especially on Island homes built through the seventies and eighties, there’s often a mud-set mortar bed over a tar or CPE membrane, and newer builds run sheet or liquid-applied membrane directly behind the backer board. Drill through that membrane and the leak doesn’t show up on the wall you drilled. It shows up in the wall cavity, sometimes months later, and by then it’s a demolition job, not a patch.

Hanging a soap dish, a grab bar, or a corner shelf inside a shower is exactly the situation where it’s worth knowing what’s actually behind the tile before drilling into it. We build blocking into the wall for grab bars and heavy fixtures during the original bathroom tile installation for this reason. Retrofitting an anchor into a finished shower wall means guessing at what’s back there, and a guess is a bad trade against a membrane you can’t see.

Mistakes That Crack Tile

Using a carbide bit on porcelain tops the list, closely followed by skipping the pilot hole and going straight for the full-size bit. Both push too much heat and pressure into a small area before the tile has any give.

Pressing hard to speed things up backfires every time. Tile drilling is slow by nature, and forcing it just cracks the glaze faster than it cuts through it.

Drilling too close to an edge or corner is another one. Tile is weakest at its edges, where a crack has the shortest path to travel. Keep any hole at least a couple centimetres from the nearest edge or grout line where possible.

Skipping the wall scanner rounds out the list, and it’s the one that turns a tile problem into a plumbing or electrical problem.

When to Call an Installer Instead of DIYing It

A single towel hook or a light picture frame is a reasonable weekend job for most homeowners with the right bit. A grab bar that needs to hold real body weight, a mirror over forty pounds, or anything going into a shower or tub surround is a different call. Structural blocking behind the tile is what makes those installs safe, and blocking has to go in before the tile does, not after.

If you’re not sure what’s behind the wall, or the item you’re hanging is heavier than a coat hook, it’s worth a conversation before drilling turns into a repair.

Frequently Asked Questions

Can I screw directly into tile?

Not without drilling first. Tile has no give for a self-tapping screw to bite into, so the screw either skates across the glaze or cracks it. Drill a pilot hole with the right bit, set an anchor, then drive the screw into the anchor.

Can I drill into tile without cracking it?

Yes, with the right bit, a taped mark to stop the drill from slipping, low speed, and steady light pressure. Water cooling on thicker tile or longer holes helps too. Most cracks come from forcing the bit or using a carbide bit on porcelain, which is built for softer ceramic.

What happens if you drill into tile the wrong way?

Cracks radiating from the hole, a chipped glaze around the edge, or a bit that burns out mid-hole and won’t finish the job. On installed tile over a wet area, the bigger risk is puncturing a waterproof membrane you can’t see from the front.

What kind of screws will go through tile?

None on their own. Screws go into anchors, not into bare tile. Plastic anchors for light loads, self-drilling tile anchors or toggle anchors for anything heavier, matched to the screw size the item’s hardware calls for.

Can you hang heavy things on tile?

With the right hardware, yes. A stud behind the tile is the strongest option if one lines up. Without a stud, a toggle anchor or a heavy-duty tile anchor rated for the weight does the job. Anything over a few pounds deserves hardware sized for it, not a plastic anchor meant for a picture frame.

Does drilling into tile void a warranty?

Depends on who installed it and what the warranty covers. Some installer warranties exclude damage from post-install drilling. Worth a quick check before hanging anything if the tile work is recent and still under warranty.
