I've read so many conflicting things regarding baths.
Are they at all helpful for hydration if the beardie doesn't drink while they're soaking? My guy doesn't particularly care for baths, but I think he may be a bit dehydrated. If soaking, alone, helps, I'll do that, but otherwise, I'll just continue to give him drops of water on his nose throughout the day.
Baths aren't very good for hydration if the beardies don't drink from them. Some people claim they absorb water through their vent, but as far as I can tell this is completely false. That said, baths are great for hydrating stuck shed and are often good for encouraging bowel movements and exercise.
If you are having trouble with dehydration issues, you might consider getting some hornworms about once every couple of weeks and adding a little bit of iceberg or romain lettuce to his salad. Hornworms are actually very healthy as well as high in moisture and most dragons LOVE them. The only problem is that they're kinda expensive - my closest supplier is $7 for 4 or $10 for 10. Oof! Lettuce, frankly, has almost no nutritional value but is wonderful for perking up dehydrated dragons.
@Ellen you can get 12 horn worms for $5.95 from Dubiaroaches.com only you haft to pay shipping - so its better to order more that just one thing ---
