By Maintenance Depot Plumbing Team · Last reviewed
Quick answer
The Centurion SFD44 is a 4"x4" square drain floor strainer that replaces rusty, broken or missing drain covers, keeping debris and pests out of the pipe.
Drain covers take a beating from foot traffic, cleaning chemicals and moisture. When one rusts, cracks or goes missing, debris and pests can get straight into the drain. The Centurion 4"x4" square drain floor strainer (SFD44) is a simple, tidy replacement.

Why replace a worn drain strainer?
- Stops hair, grit and debris from entering and clogging the pipe
- Keeps cockroaches and rats from using the drain as an entry point
- Removes a trip hazard where a cover is broken or missing
- Instantly improves how a bathroom or utility floor looks
Measuring for a replacement
- Measure the opening or existing cover edge to edge.
- Check whether the cover sits in a recess or on top of the tile.
- Note how the old cover is held: screws, friction fit or a threaded ring.
Fitting tips
- Clean the drain opening thoroughly before fitting.
- Seat the strainer evenly so it doesn't rock.
- If it sits on tile, a thin bead of silicone can hold it in place and seal the edges.
Keep drains odour-free
Run water into floor drains every week or two so the trap seal doesn't dry out.
Need a larger size? See the Centurion 6"x6" stainless drain strainer (SFD02), which also includes an odour-blocking trap.
