How often should you be clearing out your shower drain?

It's the one household task that most of us dread to have to complete: cleaning hair out of shower drains.

Whether you live alone or with family and friends, the drain of your shower is something that requires regular cleaning for bathroom hygiene and maintenance – making it important that you don’t put off the task. Input your household data below to find out how often you should be clearing out your shower drain.

About the calculator

To demonstrate just how much caught hair can interfere with the smooth running of your shower, we designed a tool that would help calculate the amount of hair that is captured in the drain over time. The first-of-its-kind calculator was created in partnership with clinical trichologist Sally-Ann Tarver, along with a study of more than ten households across the UK with different hair types and lengths.  

Ijust two weeks of not cleaning their shower drains, 3.2 grams of hair was collected from the participant’s households. Taking this group as a sample of the UK, it means that after just 24 hours the nation’s plugholes could be blocked with a combined 697 kilograms of hair – that's equivalent to nine humans, almost three grizzly bears, or 172 household cats! 

With the help of our calculator, anyone can now work out how often they should be cleaning their shower drains, based on the number of people using it, and the types of hair being washed in it. An example household consisting of four people, each with different hair lengths, will find an estimated 1.2g of hair in their drain after a month, 14.3g after a year, 143g after a decade, and 1.2kg after a lifetime. Based on this, they should be clearing their drains once every two weeks.

Ithat’s not enough to get you regularly cleaning your shower drain, then you might consider switching to a shower tray that has the convenience of an integrated custom waste system, making cleaning and maintenance faster and easier. An integrated hair catcher retains the longer hairs which can often be the cause of blockages. Located just underneath the waste cover trim, this component of our Flight Level shower trays can also be easily removed and cleaned.
