Water baths are only to be used in gerbil emergencies - for example, if something is sticking to their fur, or if the animal is in danger of suffering digestive problems or poisoning by licking its own contaminated fur. Water can remove important molecules from a gerbil’s fur and cause skin problems.
So, the gerbil version of the bath or shower is the sand bath.
