Quick answer
To fix a shower drain cover that is broken, loose or missing, measure the width of the drain opening, check whether the cover screws down or snaps in, and fit a replacement that matches. Remove the old pieces, clean the seat and fit the new cover. A solid stainless steel cover does not rust the way cheap plated ones do.
Free fix vs. permanent fix
Tighten, clean and re-seat
- Check the cover for cracks, bends and stripped screws
- Tighten loose screws and clean the seat so the cover sits flat
- Do not keep using a cracked cover, because broken edges can cut
- Replace rusted screws with stainless ones
How long it lasts: It works if the cover is only loose or dirty. A cracked, bent or rusted cover cannot be saved.
A replacement drain cover that matches your size and mount
A broken cover cannot be glued or bent back into shape. A new cover fits the same seat and keeps hair, soap and small items out of the pipe. Matching the diameter and the mount style first is the whole job.
What to get: Stainless steel replacement shower drain cover
How long it lasts: Years. A solid stainless cover will not rust or crack.

Stainless steel drain cover screws
Only if the old screws are rusted or missing
Why it happens
Rust and corrosion
Cheap plated covers rust in a damp shower. Screws seize, the metal weakens and the cover snaps.
Stripped or missing screws
Rust and over-tightening strip screw heads, so the cover cannot stay down.
Cracked plastic
Plastic grows brittle with age and cleaning chemicals. A foot, a dropped bottle or a pry bar will crack it.
A poor fit
A cover that is too small shifts and pops loose, and one that is too big will not seat in the drain.

Do these in order, starting with the simplest.
-
1. Remove the old cover
Tool used: Rubber glovesUnscrew it, or pry gently under the edge with a flat screwdriver. Wear gloves, because broken metal is sharp. Save the screws so you can match them.
-
2. Measure the opening
Tool used: Tape measureMeasure the full width of the drain opening and the distance between the screw holes. Write the numbers down. Round covers are often around 4 inches across, but check yours.
-
3. Photograph the drain
Tool used: Phone cameraTake a clear photo of the drain with the cover off: the seat, the screw holes and any notches. The photo helps you match the style when you shop.
-
4. Clean the seat
Wipe away scum and rust flakes with a rag and dish soap so the new cover sits flat. Pull out any visible hair.
-
5. Fit the new cover
Tool used: Replacement shower drain coverSet it in, line up the holes and drive the screws until snug, not tight. A snap-in cover presses down until it clicks.

When free fixes aren't enough
If the cover is cracked, rusted or missing, tightening will not help, and an open drain lets hair and small items into the pipe. A matched replacement is the fix. If the screws are rusted in place and will not come out, or the drain flange itself (the ring the cover sits in) is cracked, loose or leaking, a new cover is not enough, and a plumber should replace the drain body. If the drain is slow, the problem is hair in the pipe and not the cover.

How we picked: How we picked: this page is based on shower drain repair guides, parts descriptions from drain makers and the problems and fixes people report in owner reviews. We do not test products by hand.
Round, square or linear: match the shape
- Round: the most common. Measure across the widest point.
- Square: measure one side, and check for tile-in versions.
- Linear: a long, narrow grate. Measure its length and width, and check that the grate is separate from the channel.
What to skip
Gluing or taping a broken cover
Epoxy, super glue or tape on a cracked cover hides the break for a day. Then sharp pieces and loose bits fall into the drain. A new cover costs little and fixes it properly.
