Cold Or Hot?
Breeders, keepers and even VETS often recommend showers, baths it soaks or wraps in warm water...
While direct showers, baths and soaks are an absolute NO in chameleon husbandry, as they lead to heavy discomfort and stress and must NEVER be done, contact of water e.g. in form of wraps are sometimes necessary for therapeutical purposes (hemipeneal plug removal, emergency measures in cloacal prolapse etc.)
The problem is the human perception of this non-concrete terms...
You just need to attach concrete values to it otherwise it does not make sense to discuss...
The average optimum temperature of the commonly kept chameleon species is around 72-76*F (22-25*C)
Do not overheat the chameleons!
Use COLD WATER, best at room temperature!
