Yes, a special door is needed for a steam shower to contain the steam and prevent it from escaping into the bathroom. A regular shower door is not enough as it may not be properly sealed to withstand the high levels of moisture and heat created by the steam. Here are some things to consider when choosing a door for your steam shower:
Look for a door made of tempered glass that is at least 3/8 inch thick to ensure it can withstand the high temperatures of the steam.
Choose a door with a tight seal to prevent steam from escaping into the bathroom. Look for doors with a magnet or compression strip to ensure a tight fit.
Consider a door with a transom window to allow for ventilation and prevent a buildup of steam inside the shower.
Make sure the door and hardware are made of materials that can withstand the moisture and heat of a steam shower, such as stainless steel or brass.
In summary, a special door is needed for a steam shower to prevent steam from escaping and causing moisture damage in the bathroom. Look for a door that is made of tempered glass, has a tight seal, and is made of materials that can withstand the high temperatures and moisture of a steam shower.
