I have never done this... and I was wondering, if you guys know the answer...
I have other reptiles... [tortoises (sulcata and gophers), and a green iguana]
They all love and benefit from warm soaks.... has anyone tried this on chameleons?
Yea, chameleons are more comfortable with a warm shower than a literal soak. But essentially the effect is the same, as are the benefits. I just have my misting nozzles set to spray for a long time but some people will take their chameleon on a plant into their shower/bath tub and give them a warm shower that way.
Obviously, don't spray your chameleon directly with your shower head, but typically bouncing the spray off the wall will produce a much finer mist. I use a pump sprayer, personally. And also, when I say warm I really mean luke-warm, because chameleons feel temperature differently than we do. So warm for us would be really hot for them.
I have a pump sprayer that I use to mist w/ "Luke" warm water. After a good misting, I fill his dripper with the warm water. He'll sit directly under the dripper for what seems to be hours. Dripping directly on his head and / or back. He seems to like that.
