This is up to the individual but most resources recommend a maximum steam shower length of no more than 20 minutes.
How do you use a Mr steam shower?
Steam, heated to 110 relaxing degrees, enters the shower enclosure through steam heads. You sit in total comfort, taking in the steam for 10 to 20 soothing minutes, followed by a refreshing shower. Now wrap yourself in the comfort of a fluffy towel heated by a towel warmer to complete the total spa experience.Sep 3, 2013
