Linear drains are extremely resistant to blockages. However, if your wet room drain does become blocked, there are a few steps you can take. An effective way of unblocking a wetroom drain is to lift the cover and access the waste trap.

Once the cover is removed you can clean out the waste trap by lifting the seal tube and accessing the belly of the waste trap. 

If the blockage is further down the line. you can use this access point to snake the drain if necessary.
