Quick answer
A shower door drifts open when the door, track or hinges sit slightly off level and gravity pulls it, or when the old magnet strip has cracked or lost its pull. Check the level and adjust the rollers or hinges for a free fix. Then fit a magnetic catch. It holds the door shut with a gentle pull, even if the door is a hair out of level.
Free fix vs. permanent fix
Level it, adjust it and clean it
- Check the door and track with a small level
- Adjust the rollers or tighten the hinges so the door hangs straight
- Clean the track, the rollers and the edge of the magnet strip
- Test whether the door stays where you leave it
How long it lasts: Months, if a tilt was the cause. If the magnet is weak or missing, the door drifts again.
A magnetic shower door catch
An uneven curb or a leaning wall means you may never get a perfect level. A magnet does not need one. The door clicks shut and stays there, and it works even when the hinge or roller is a hair off.
What to get: Magnetic shower door catch (magnet with strike plate)
How long it lasts: Years. A magnet on the door and a steel plate on the frame hold it shut with a light, steady pull.

Why it happens
An out-of-level door or track
If the curb or the door slopes, even slightly, gravity moves the door. A sliding door rolls toward the low side. A hinged door swings toward it.
A worn or missing magnet strip
Hinged frameless doors usually close on magnetic strips along the seal. Over time the strip cracks, peels or loses its pull.
Misaligned or worn rollers
Rollers set at different heights tilt a sliding door. Worn wheels make it ride unevenly and coast along the track.
A loose or sagging hinge
On a hinged door, a hinge that has loosened leans the door, so it swings open on its own.

Do these in order, starting with the simplest.
-
Check the level
Tool used: Small levelHold a small level against the vertical edge of the door and along the track or curb. Note which way it leans. The door will drift toward its low side.
-
Adjust the rollers or hinges
Tool used: ScrewdriverOn a sliding door, turn the roller adjustment screw on the bottom edge a little at a time to raise the low side until the door hangs straight. On a hinged door, tighten the hinge screws. Hold the glass steady and never pry on it.
-
Clean the track and the contact points
Tool used: Soft cloth and white vinegarWipe the track, the rollers and the edge of the magnet strip with a cloth and white vinegar, and dry it. Soap scum and grit make a door ride badly and stop the magnets touching cleanly.
-
Fit the catch
Tool used: Magnetic shower door catchClean the glass edge and the frame where it will stick, and dry them. Fit the magnet on the door and the plate on the frame or the next panel, check they meet, then press firmly. Give any adhesive the cure time on the pack before you shower.

When free fixes aren't enough
Adjusting only helps if a tilt is the cause, and a perfect level is not always possible with an uneven curb or a tilted wall. A magnet covers that gap. If the door is also sagging, scraping or the rollers are visibly worn, replace the rollers or the hinges. If the glass is cracked, or chipped along an edge, or the frame is bent, stop and call the installer. Damaged tempered glass can shatter.

Magnetic shower door catch (magnet with strike plate)
Fixes: a shower door that drifts open on its own
Look for: A design for glass shower doors, with a mount for your door style, sliding or hinged; An adhesive or clamp-on mount, with no drilling into the glass; A strike plate that lines up with the magnet; A housing that will not rust.
- Who it's for
- Anyone whose door is level enough but will not stay closed.
- Honest downside
- Your hinge is badly sagging or the rollers have failed. A catch holds a door shut, but it does not fix one that drags or scrapes.
Replacement magnetic seal strip for frameless hinged doors
Fixes: a hinged door whose factory magnet strip has cracked or lost its pull
Look for: A length that matches your door edge; A channel width for your glass thickness, which is often 3/8 inch on frameless doors; A strip with the magnet already built in, not a plain seal.
- Who it's for
- Anyone with a hinged frameless door and a peeling or cracked strip.
- Honest downside
- You have a sliding door, or you cannot confirm the glass thickness. A strip that does not fit will not hold.

Which door do you have?
- Sliding (bypass) door: usually needs a level track and a catch where the door meets the frame or the fixed panel.
- Hinged frameless door: check the magnet strip on the closing edge, then the hinges.
- Hinged framed door: the frame holds the magnet, so a loose hinge or worn magnet is the usual fault.
What to skip
Tape, glue and wedged towels
Tape peels in the steam, glue is hard to remove from glass without scratching, and a wedged towel traps moisture and mildew. Never drill tempered glass. It can shatter. Use a catch that sticks on or clamps on.
