How to Choose and Fit a Replacement Shower Drain Cover
The small part that ruins a nice bathroom
You can scrub a shower tray until it gleams and still have it look neglected, because the eye goes straight to the drain. A waste cover that has gone cloudy, picked up limescale, or lost its shine drags the whole space down. It is one of the few bathroom parts that gets soaked several times a day and then left to dry on its own, so it ages faster than the tiles around it.
Then there is the other problem. Hair. Every shower sheds some, and a cover that no longer sits right lets it slip past into the trap. Once hair gets into the pipe it knits together with soap residue, the water starts draining slowly, and eventually you are standing in a puddle wondering whether you need to call someone.
A replacement cover and catch cup solves both of those at once, and it costs a fraction of what a plumber charges to clear a blocked trap.
How this type of drain cover actually works
There are two parts here, and they do different jobs.
The visible piece is the chrome cover, 115mm across. It is the bit you see when you look down at the tray. It does not sit flat and sealed. It stands proud by 70mm, which leaves a deliberate gap all the way around for water to run under and away. That raised design is the reason the tray keeps draining at a normal speed rather than backing up around your feet.
Underneath sits a cup. The cup is the quiet workhorse. Water drops into it, carrying whatever has washed off you, and the cup holds back loose hair and debris while letting the water continue on into the trap below. When it fills, you lift it out and tip it into the bin.
That is the whole mechanism. No filters to replace, no moving parts, nothing to wear out. It is simple, and simple is exactly what you want in something that lives in standing water.
Who this suits
This is for anyone with a shower tray that uses a fast flow 90mm waste with a lift-out cover and cup. That is a very common arrangement in modern trays, particularly in the UK and across Europe.
It suits households with long hair especially well, because a removable shower hair catcher saves you from the monthly ritual of poking something down the plughole. It also suits renters, since nothing is cut, glued, or sealed. You keep the original parts in a drawer and swap them back when you leave.
It suits anyone doing a light bathroom refresh too. If you have changed the taps or put up a new shower rail, a bright chrome shower waste cover ties the look together for very little money. And it suits the practical case where the old cover has simply snapped, warped, or gone missing.
It does not suit baths, which use a different and smaller waste. It does not suit square or rectangular wet room gullies. And it does not suit wastes where the cover is screwed down or siliconed in place, because those are a different design entirely.
Measure first, order second
This is the one step people skip and the one step that matters most. Shower wastes are not fully standardised, and a 5mm difference is the difference between a part that drops in and a part that rattles or will not seat.
Take the old cover out. You will need three measurements.
First, the diameter of the waste opening in the tray itself. This product is made for a fast flow 90mm diameter waste hole. Second, the diameter of the old cover you have just removed, to compare against the 115mm face here. Third, the depth of the recess below where the cup sits, so you know the new cup has room to drop in without standing proud.
Write them down. Compare them to the figures on this page. If all three are close, you are good. If the opening is noticeably smaller or larger, look for a different size rather than hoping it will do. A cover that does not seat properly will shift under your foot and let hair past, which defeats the point.
Fitting it
There is almost nothing to it. Pull the old chrome lid up and off. Lift out the old cup underneath and set both aside somewhere safe, especially if you are renting. Give the recess a wipe, because there is usually a ring of soap scum and grit sitting there that you have never actually seen.
Drop the new cup into the recess, making sure it sits down flat rather than catching on an edge. Then press the chrome cover into place on top. Run the shower for ten seconds and watch the water clear. If it drains away at the usual speed and the cover stays seated, you are done.
No tools. No sealant. No turning the water off at the mains.
Keeping it clean
A drain cover is only as good as the last time you emptied it, and this is where a lift-out design earns its keep.
Every week or two, pull the chrome top off with your fingers and lift the cup out. Tip the contents straight into the bin, not back down the drain. Rinse both parts under warm water at the sink, wipe them with a soft cloth and a drop of mild washing-up liquid, and dry them before they go back in. The whole thing takes about a minute.
In a busy family bathroom, or where anyone has long hair, make it every few days instead. It is far less unpleasant to empty a cup with a few days of hair in it than one with a month.
What to avoid matters just as much. Keep bleach, scouring pads, and abrasive cream cleaners away from the chrome. They strip the shine and can leave fine scratches that trap grime. If you live in a hard water area and limescale is building up, a short soak in warm water with a splash of white vinegar, then a proper rinse, is gentler than a strong descaler.
Drying the cover after cleaning also reduces those chalky white spots that form when hard water evaporates on metal.
When the problem is not the cover
Sometimes you fit a new cover and the shower still drains slowly. That tells you the blockage is further down, in the trap or the pipe, and no cover will fix it.
The usual sign is water draining slowly even with an empty cup. In that case, clear the trap properly first, then fit the new cover. Starting clean means the catch cup can do its job from day one instead of fighting a build-up that was already there.
A faint drain smell is the same story. Smells come from what is sitting in the trap below, so clean that and the smell goes with it.
The short version
A worn shower waste cover is a cheap fix with a visible payoff. This one is a two-piece set, a 115mm chrome cover that sits proud by 70mm for flow, and a removable cup underneath that catches hair before it reaches your pipes. It is made for a fast flow 90mm waste hole, it drops in without tools, and both parts lift out by hand so cleaning takes a minute rather than an evening.
Measure your waste opening before you order. If it matches, this is about as easy as bathroom jobs get.
