Does the steam room need to be insulated?
Insulation in the walls and ceiling will make the room easier and more economical to heat. Also, insulated walls will reduce exterior noises from disrupting the tranquil environment inside the steam bath. Insulation is highly recommended. Should I install an exhaust fan or special ventilation in the steam room / shower? Ceiling vents inside the steam room are not recommended or necessary. Steam is quickly dissipated when you turn on the water to shower after ending your steam bath. If vents or exhaust fans are used, they must be installed with a vapor-tight seal and have a positive closing damper to prevent heat from escaping. Many people install an exhaust fan in the ceiling near the steam shower door to remove excess steam when the door is opened.
