How cruel... I hope your bath enamel cracks!
Spiders get an unfairly bad rap - they're amazing creatures. Watching them construct a web is awe inspiring... And particularly in countries where they are harmless, I just don't get the hatred for them... They're not going to hurt you. Pick em up (in a glass or on cardboard) if necessary and put them outside. I take them out of the bath so they don't drown and back under the radiator.
