tegenaria gigantea The common house spider. I just found this big ol' girl in my bathtub. I love these spiders which live with us most of the time. If you've ever found one of these and put it outside you were wasting your time as it was probably back in your house within minutes The human house is their 'natural' habitat. No-one is quite sure where they used to live before people came along. It's a female, the males are much smaller and rather insignificant. I've draped a piece of toilet paper over the edge of the bath so she can find her way out, she's welcome to share my humble home, and she'll clear out the 'cobs'!
