I give baths, but only when they drag their tails through their poo and get gross. Otherwise I don't. Or when they're extremely smelly, and I have someone coming over who I know will want to hold them. It's not like.. a bath bath? More like a soak and rub down with a cotton ball. They're geckos, so I let them be. Plus they shed every other week for me, which essentially is getting rid of the "stink"y skin.
