Found in top corner of my separate toilet room, which is generally dark. It is difficult to determine size because of the height. I suspect the body is slightly smaller than a dimes diameter. With it's legs in the position in Photo 1, I think it's entire size is close to the Kennedy half dollar coin.
Af first, I was hoping it was a desert recluse, but after doing a little research, I think it might simply be a southern house spider. I do live in the desert, in a housing community that is less than 20 years old close to the San Tan mountains.
