Most likely cause & what to check
Remove the shower drain cover — it usually clips or screws off. Wear rubber gloves.
Pull out any hair and soap build-up from the drain entry — this is almost always the cause of slow draining showers.
Use an old toothbrush and warm water to scrub the drain cover and trap.
Pour a kettle of hot (not boiling) water down the drain to flush loosened soap scum.
If still slow, use a drain unblocker gel — leave for the time stated on the packaging then flush thoroughly with hot water.
If the drain is still blocked after this, the blockage may be further down the waste pipe. A plumber's drain snake or high-pressure jetter may be needed.

Frequently asked questions
How often should I clean my shower drain?
Once a month prevents major blockages. A drain hair catcher (£2–5) placed over the drain is the easiest prevention method.
Can I use bleach to unblock a shower drain?
Bleach kills bacteria and deodorises but doesn't dissolve hair or soap effectively. A proper drain gel containing sodium hydroxide works much better.
