Daughter goes poop in bathtub

Hello, my 2 year old daughter loves to go potty in the bathtub. We aren’t actively potty training her so I can’t be too upset but before we take off her diaper we always ask if she has to go in her diaper. Pee isn’t a big desk but if she poops we have to give her another bath. Do any of you moms have any suggestions or tips or how to deal with this?
