Some cats dont mind water at all and some will do anything to stay away from it. I know a family that has a cat that was given a bath every few weeks since it was a kitten and she will just lay in the tub while you wash her.
Used to have one that would lay on its back in the kitchen sink & turn the Delta faucet on by batting at it with it's paws. Then it would lay there for an hour swatting away at the stream of water making a huge mess. Twenty year ago. Could have been a YouTube millionaire...
Had a big fluffy white cat, purina cat food style, that loved to wade into the bath water. Ex-wife had a rough day, so drew her a bath with candles. White cat proceeded to catch itself on fire and torch off all her belly hair. Burnt cat hair smells like shit.
If you leave the water running, my cat will lay down in the sink when you brush your teeth. She will also get in and help with dishes if the sink is partially empty and yes she does go in the shower too.
