This is an absolutely fabulous idea! Depending on the space you have, I would recommend putting a tub or a plunge pool within the steam shower enclosure. This not only allows for cooling off to lengthen your steam bathing session, it adds an additional 'cool surface' for the steam to interact with and create a thicker fog, the sound of water running or sloshing is very relaxing, and the effects of a 'cold plunge' on the body is very invigorating while kicking up the cardiovascular benefits of this type of bathing.
