You gotta be careful with soaking substrate very well it has to be wet but not soaking wet, not mud like.

Bath i actually do it for mine once a month at least when changing substrate, just because, my male is a VERY lazy one lol

bath to help with shedding- warm treated water, i usually stick my hand in, if it feels warm, not going osd over exact temp. I would think it should be about 82. Water level no higher then frogs chin, otherwise it might drown, keep a frog in there for like 20 min, rub very very gently sides, dont use any force taking skin out, it should go on its own. You might need to do it a few times depending how bad the situation is.
