we tend to do at least a quick dip in the kitchen sink every night, though typically every other night for a tub bath..depending on how entertaining the self feeding was that night..
We usually strip him to a diaper before putting him in his chair, so his favorite thing to do at the end of the meal is to stand in his chair so I can unhook his diaper,,the we do the "Naked Baby Flying" chant as he zooms to either the sink or the bathtub..
I have recently caught him trying to get his leg over the bathtub to climb in during the day..that's all good until he figures out how those magical faucets work too!
If I or Daddy hop in the shower downstairs he will side open the shower door and come in, usually wearing his nightshirt/diaper and socks,,,,I have learned to strip him when I strip just incase he decides to join me! Interestingly, when Josh climbs into the shower, his kitten Aslan will come in too! he will sit in the corner for a minute or so,,then slink out..anything to be with his baby!
