shower cubicle drain problem

[Philious]

When I use the shower the cubicle fills up and the water drains away really slowly, anyone any ideas why this is happening. When we bought the house a couple of month back it worked fine until last week, no similar problems with any other outlets.
Thanks

It's blocked, that's why.

Stick some of this down it:
