What is the best height for a steam room / steam shower? Heat rises, therefore having a low ceiling makes it easier and more economical to heat, and also makes the room warmer at low-level, which is where you are sitting. Whilst a lower ceiling height is a good thing for steam, it is not critical. Helo recommends 2.1m as an ideal ceiling height. - - - - - - - - - - - - - - - - |
