How to Reduce Condensation in Bathrooms

Ellen Ciurczak

Condensation in the bathroom can become a problem after steamy showers. If the surface of walls, tiles and porcelain is cold enough and there is enough hot water vapor in the air, condensation will form. The problem is that when there is condensation, mold and mildew follow.

Reducing condensation in the bathroom will lower the risk of mold and mildew.
  1. Take shorter and cooler showers so that less heat and moisture is released into the air. In addition, use a squeegee to remove water from shower walls when you're done. That reduces the amount of water that will evaporate into the air.

  2. Install an electric exhaust fan in the ceiling, and use it every time you bathe or shower. Make sure that it's sized for your square footage. Most condensation is caused by poor ventilation. The fan will remove hot, moist air from the bathroom.

  3. Bring a portable dehumidifier into the room to remove moisture from the air and store it as water in a reservoir. Empty this reservoir regularly, or the water will evaporate back into the air.

  4. Remove carpet from the bathroom. Carpet holds moisture, which keeps the humidity level high and contributes to condensation. Consider alternative floor coverings, such as tile made especially for bathrooms.

  5. Take damp towels to another room to dry. This will also reduce the amount of moisture evaporating into the air.

  6. Remove potted plants. The soil in potted plants holds water and contributes to condensation. Water also evaporates off plant leaves.

  7. Check for leaks. Even a small leak can add to humidity and condensation and cause mold growth. Check all water supply pipes, especially around connections. Take a close look at the shower pan and bathtub to make sure all drain seals are intact.

    You can try opening your bathroom window to vent the room, but this may prove uncomfortable during winter months.
