Urinal Screens: What They Do and Which Type to Buy
Urinal screens are perforated mats or domes that sit in the bottom of a urinal. They filter out debris so the drain stays clear, break the flow of liquid so it splashes less, and release a fragrance or enzyme that controls odour. Most are plastic or rubber, and you swap them on a set cycle.
What do urinal screens actually do?
Urinal screens do three jobs at once. The perforated surface catches chewing gum, cigarette ends and other debris before it reaches the drain, so blockages are less likely. The raised pattern breaks the flow of liquid so less bounces back onto the floor and shoes. The fragrance or enzyme in the material then works on the smell.
The smell in a urinal does not come from the liquid itself. It comes from bacteria breaking down uric salts that build up in the bowl and the trap. A dry, dirty urinal will often smell worse than a wet one for that reason. A screen sits right where the build-up starts, which is why a cheap piece of moulded plastic makes such a clear difference to how a washroom smells.
Splash-back matters more than most people expect. Liquid that lands on a flat porcelain base bounces out onto the floor, where it soaks into grouting and keeps smelling long after the urinal has been cleaned. A screen with a domed or ribbed surface absorbs most of that energy and keeps the mess in the bowl.
What types of urinal screen can you buy?
Screens come in a few shapes. Flat mats cover the whole base of a bowl urinal. Domed or convex screens sit over the drain outlet in a wall-hung urinal. Trough screens are long strips for older trough urinals. On top of the shape, you choose between plain, scented and enzyme versions.
- Flat mat: covers the base of a bowl or floor urinal, holds debris across the whole surface.
- Domed screen: sits over the outlet in a wall-hung urinal, a common commercial format.
- Trough strip: a long mat for continuous trough urinals in older premises.
- Scented: releases fragrance for a set period, the standard washroom choice.
- Enzyme: carries live bacteria or enzymes that break down uric salts in the trap.
| Type | Best for | What it gives you |
|---|---|---|
| Plain screen | Low-traffic staff washrooms | Debris catch and less splash-back |
| Scented screen | Most shops, offices and venues | Debris catch plus a fresh smell |
| Enzyme screen | Busy pubs, clubs and stadiums | Attacks the source of the odour |
| Trough strip | Older trough urinals | Full-length cover for one long bowl |
Are enzyme screens worth paying more for?
Enzyme screens are worth it where a washroom is busy or where a smell keeps coming back after cleaning. A scented screen covers odour. An enzyme screen releases bacteria that feed on the uric salts causing it, so the problem gets smaller instead of being masked. In a quiet staff washroom, a scented screen is usually enough.
The test is simple. If the urinals smell clean for a day or two after a screen goes in and then turn again, you have build-up in the bowl and the trap, and an enzyme screen is the better buy. If a scented screen holds up for its full life, stay with it and save the money.
Do you still need urinal blocks?
Urinal blocks and screens are not the same product. A block is a solid tablet that dissolves slowly to deodorise and help keep the trap clear. A screen is a mat that filters debris and cuts splash-back as well as scenting. Many washrooms run both, a screen in the bowl and a block or cage sitting on it.
If you are choosing one, take the screen. It covers more of the job. Blocks are worth adding where a urinal has a history of blocking or where the flush is weak, because they keep working on the trap between flushes.
How often should you change a urinal screen?
Change urinal screens on a fixed cycle rather than waiting for someone to complain. Most screens carry a stated life on the pack, and busy washrooms burn through them faster than that. Put the change on the same schedule as your deep clean, and write the date on the screen or a clipboard so nobody has to guess.
Three signs say a screen is finished. The scent has gone flat. The colour has faded or the material has gone brittle. Debris has clogged the perforations so water pools on top. Any one of those means replace it, and give the bowl a proper clean at the same time so the new screen starts on clean porcelain.
Keep a small buffer in the store cupboard the same way you do with commercial toilet rolls and paper hand towels. Screens are cheap, and running out is the point at which a washroom starts to smell.
What else keeps a washroom smelling fresh?
A screen handles the urinal. The rest of the room needs a short routine to go with it:
- Clean the floor around and behind the urinal, that is where old splash sits.
- Keep soap, hand towels and toilet roll topped up so people are not touching surfaces they should not.
- Empty and reline bins before they fill, using the right bin liners and refuse sacks for the load.
- Add an air freshener or dispenser for the room itself, not as a cover for a dirty urinal.
- Wipe down cisterns, handles and taps with the right cleaner for the surface.

Frequently asked questions
What do urinal screens do?
Urinal screens do three jobs. The perforated mat catches gum, cigarette ends and other debris before it can block the drain. The raised surface breaks the flow of liquid so less splashes onto the floor. The material also carries a fragrance or an enzyme that works on the smell in the bowl.
Do urinal screens actually work?
Yes, within reason. Urinal screens deodorise, reduce splash-back and keep debris out of the drain, which keeps washrooms fresher and the urinal cleaner between services. Enzyme or scented versions also help control odour at the source. They are not a substitute for cleaning, but they make a clear difference to how a washroom smells and how often it needs attention.
What is the difference between a urinal screen and a urinal block?
A urinal block is a solid tablet that dissolves slowly to deodorise and help keep the trap clear. A urinal screen is a perforated mat that filters debris, cuts splash-back and scents the bowl. Screens cover more of the job, so pick a screen first and add a block where a urinal blocks often.
How often should urinal screens be changed?
Change them on a fixed cycle rather than waiting for a complaint. Follow the life stated on the pack and shorten it in busy washrooms. Replace a screen once the scent goes flat, the material fades or goes brittle, or debris clogs the holes so water pools on top. Clean the bowl at the same time.
Are enzyme urinal screens better than scented ones?
Enzyme screens suit busy washrooms and any urinal where the smell keeps returning after cleaning. They release bacteria that break down the uric salts causing the odour, so the build-up gets smaller. Scented screens mask odour instead. In a quiet staff washroom, a scented screen is usually enough.
Do urinal screens stop blockages?
They help a lot. Most urinal blockages start with solid rubbish going down the outlet, chewing gum, cigarette ends, bottle tops and paper. A screen catches all of that on top, where cleaning staff can lift it off and bin it. It will not clear a trap that is already blocked with scale.
