Shower spider

[mtbc]

I was surprised to find a spider in the shower cubicle this morning. As I shower daily I thought that there would be a U-bend typically water-filled, presenting a barrier to creatures entering via the drain. Perhaps I am mistaken, or maybe the spider simply made its way into the shower from some other part of the house, though we typically keep that bathroom door closed because the cat has a penchant for stealing our dirty underwear (Phase 3: Profit) from therein.
