Steam accumulation in a bathroom after a shower can lead to mildew growth and warped trim work. It also can fog up the mirror, and stain the walls and ceilings with hard water drips. It doesn't matter if your bathroom has a window or not, this problem can be stopped. When the warm moist air from the shower mixes with the cooler air in the bathroom, condensation forms on the bathroom surfaces. Adequate air ventilation takes care of this problem.
Turn on the bathroom exhaust fan. This will suck the moist air up and out of the room.
Open the bathroom window and door to create cross ventilation.
Plug in a ventilation fan and set it on the floor. Direct the air flow toward the open window. The idea is to blow the moist air out of the bathroom so it stops the steam effect. Dry air stops steam.
Turn the thermostat up so that the bathroom air temperature is at or above 70 degrees Fahrenheit. Cold air mixing with warm air creates more steam.
