Quick answer
To fix a bathroom mirror to the wall without drilling tile, bond it with a mirror-safe adhesive and hold it in place until it cures. Ordinary construction glue can eat the mirror's reflective backing, so choose an adhesive labeled for mirrors. Tape and a ledge carry the weight while the glue sets.
Free fix vs. permanent fix
Prep, level and lean
- Clean the wall with rubbing alcohol
- Mark the position with painter's tape and a level
- Rest the bottom edge on the vanity ledge
- Do a dry fit before any adhesive goes on
How long it lasts: Only for small, light mirrors. A glass mirror leaning on a ledge is not secure and can fall if someone bumps it.
Mirror-safe adhesive with temporary support
Mirror adhesive bonds the glass to the tile with no holes. Tape and a ledge carry the weight while it cures. Regular glue can damage a mirror's silver backing, so the label matters.
What to get: Mirror mounting adhesive
How long it lasts: For the life of the mirror, as long as the wall stays dry and sound.

Why it happens
Tile is hard and brittle
A standard drill bit skates across glazed tile and can chip or crack it. Even a proper tile bit needs patience, and one slip leaves a damaged tile.
Mirrors are heavy
A mid-size glass mirror can weigh 15 to 25 pounds. Weak tape or small anchors let go over time.
Regular adhesive can attack the backing
Some construction glues contain solvents that can eat the silver and paint on a mirror's back. That leaves dark patches that creep in from the edges.
Steam and soap film
Bathroom walls collect a thin layer of soap and moisture. Weak adhesives cannot grip it, so the wall must be clean and dry.

Do these in order, starting with the simplest.
-
Pick the spot and mark it
Tool used: Level and painter's tapeHold the mirror up with a helper and look at it from where you will stand. Mark the top and bottom edges with painter's tape and check it with the level.
-
Clean the wall
Tool used: Rubbing alcohol and ragWipe the tile with rubbing alcohol on a rag. Remove soap scum, wax and dust, and let the wall dry. If it is damp or mold-stained, fix that first.
-
Dry fit with a helper
Tool used: A helperRest the bottom edge on a ledge or a stack of folded towels on the vanity. Check the position and level, and see that the mirror does not rock.
-
Apply the adhesive
Tool used: Mirror-safe adhesiveCut the nozzle and load the tube. Put vertical strips or dabs on the back of the mirror, keeping them away from the edges. Follow the layout printed on the tube.

Press, tape and wait
Tool used: Level and painter's tapePress the mirror into place with firm, even pressure, then tape the top and sides to the wall. Leave it for 24 hours, or the time on the label, before removing the tape. Keep the shower off until then.
When free fixes aren't enough
Leaning a mirror on a ledge only works for small, light ones. For a mid-size or large mirror, the adhesive does the real holding. Stop if the wall behind is crumbling, wet, or the tile is loose, because the mirror will not hold on a weak wall. For a large, wide vanity mirror, ask a pro to help. A fall can hurt, and broken glass is dangerous.

How heavy is your mirror? Check before you glue
Glass is heavy. A 24 by 36 inch mirror made from 1/4-inch glass weighs about 20 pounds, and a wide vanity mirror can weigh much more. Check the maker's label, or weigh it by standing on a bathroom scale with the mirror and subtracting your own weight. Match the adhesive and any clips to that number, and keep a helper on hand.
What to skip
Construction adhesive and foam tape
Some construction adhesives contain solvents that can damage a mirror's backing, and general foam tape is not rated for heavy glass in a steamy room. If the mirror weighs more than the package says, the tape can slip. Use an adhesive made for mirrors instead.
