What we cover
Start with the wall, not the anchor
For a light bathroom accessory such as a soap dish, toilet-paper holder, or small towel hook, the best anchor depends on what sits behind the tile. Tile is a brittle finish, not a reliable place to grab with a screw. The anchor needs to reach the material behind it, and the hole must be drilled without cracking the tile.
Check for a stud or solid wood blocking first. A stud finder can help, but tile, metal corner bead, and plumbing can confuse readings; verify cautiously and avoid drilling where pipes or wiring may run. If a stud is in the right place, use a suitable screw into the wood rather than a plastic wall plug. For a small accessory, that is usually the strongest, simplest fixing.

If there is no wood behind the mounting point, identify the substrate: drywall, cement backer board, or masonry. A hollow-wall anchor that works in drywall may not work in tile over cement board or a solid wall. When you cannot tell what is behind the tile, inspect an existing opening or ask whoever installed the bathroom before choosing hardware.
Which anchor suits the job?
For an accessory with two mounting screws, distribute the load across both fasteners, but do not assume the rated capacity of two anchors simply doubles. Ratings depend on the wall material, installation, and direction of force. A towel hook pulled outward can stress a fixing more than the same weight hanging straight down. Avoid using a small bathroom accessory as a grab bar; grab bars need dedicated structural support.
| Fixing | Best use | Trade-off |
|---|---|---|
| Screw into stud or blocking | Any accessory that lines up with solid wood | Strong and dependable, but the holes must land on the wood |
| Plastic expansion plug | Light accessory in suitable solid masonry | Inexpensive; unsuitable for a hollow cavity or unsupported tile alone |
| Toggle or metal hollow-wall anchor | Tile over drywall or another hollow wall, where the anchor fits the cavity | Can hold well in the wall, but needs a larger hole and enough clearance behind it |
| Adhesive mounting system | Very light accessory on a clean, compatible surface | No drilling, but performance depends on surface, moisture, cure time, and load |
A toggle or metal hollow-wall anchor assortment can be useful for tile over a hollow wall, but check the package’s required hole size and wall-thickness range before buying. The tile and any backer board count toward the material the fastener passes through; some toggles need more cavity depth than the wall provides.
For tile over solid masonry, choose a masonry fastener and plug sized for the screw and substrate, not a drywall toggle. For light loads in sound masonry, a nylon masonry plug set is often the economical choice. If the accessory maker supplies suitable screws and anchors, use those instructions as the starting point.
Drilling tile without chipping it
Use a carbide spear-point bit intended for tile on many ceramic tiles. Porcelain is harder; a diamond tile bit is often the better choice. A standard twist bit can skate across the glaze, overheat, or damage the surface. Match the bit diameter to the anchor’s specified hole—not just the screw diameter—and check whether the anchor must also pass through backer board.
Mark the hole through the accessory’s mounting plate, then move the plate aside. Keep holes away from tile edges and corners when the layout allows; those areas are more vulnerable to cracking. Put painter’s tape over the mark to help control bit wandering, and use a level to check the layout. Start slowly with the drill in regular rotation, no hammer mode. Hammer action can crack tile. Use light pressure and let the bit cut; forcing it or running it dry at high speed can overheat the tip.
Once through the tile, change to a bit suited to the material behind it. If the wall is masonry, use a masonry bit after clearing the tile layer. Hammer mode may be appropriate only after the bit is past the tile and only if the substrate and job allow it. For drywall, do not use a masonry hammer-drilling approach. A diamond tile drill-bit set is worth considering for porcelain or several holes; for one hole in softer ceramic, a suitable carbide tile bit is usually the cheaper choice.
Fit the anchor and test the fixing
Vacuum or blow out debris from the hole before inserting the anchor. Do not hammer a plug into a hole that is too small: that can stress the tile and create a crack that appears later. If a toggle’s wings cannot open freely behind the wall, do not force it; choose a compatible anchor or a different mounting position. Tighten the screw until the bracket is secure, then stop. Excessive torque can strip the anchor, crush drywall, or crack tile.
Before hanging the accessory, check that the bracket sits flat and does not rock. Tighten its set screw if it has one. Apply a steady, gentle pull to the mounted piece; stop if the bracket shifts, the screw turns without tightening, or you hear a crack. Remove the fixing and reassess rather than loading a questionable hole.
When not to drill
Adhesive accessories avoid tile holes, but they are a poor choice where users will pull hard, where the surface has soap film or textured grout, or where the product’s instructions exclude wet areas. Clean and dry the tile exactly as directed, observe the stated cure time, and stay below the product’s load limit. Adhesive is a reasonable low-cost option for a lightweight item that can be replaced if it releases; it is not a substitute for a structural fixing.
If the tile is cracked, the wall sounds hollow, the accessory must carry substantial force, or you cannot identify the wall construction, pause before drilling. A small bathroom fitting rarely justifies damaging a tile or taking a chance on a weak fixing. Relocating the bracket to a stud or getting a tile installer to advise on the wall may cost less than repairing the surface.
