Azygous has posed this question to me…
Why does my cat like to take showers with me? Really, he just loves the water.
Although I can’t answer why your cat takes showers with you, I can tell you that my cat takes showers with me because she loves me. She has always liked water as well, and as a kitten would sit IN the sink while I washed my face and brushed my teeth. She’d stick her face under the dripping faucet, then sneeze when the drips got up her nose. When I moved to my new place here in the middle of nowhere, I was disapointed that the shower has a sliding glass door preventing my kitty from pushing her way through the curtain and sitting on the edge of the tub while I showered.
