Why Your Bathroom Always Feels Damp and How to Fix It

A damp bathroom isn’t just uncomfortable—it can lead to mould, mildew, and unpleasant odours. If your bathroom always feels damp, the culprit is likely poor ventilation. Understanding how moisture builds up and how to get rid of it effectively is key to keeping your bathroom fresh and dry.

Why Bathrooms Stay Damp

Bathrooms are naturally humid spaces. Every time you take a shower or bath, warm moisture-laden air fills the room. If this air doesn’t have an efficient escape route, it condenses on walls, mirrors, and ceilings, leading to persistent dampness.

The Common Ventilation Problems in Bathrooms

1. Insufficient or Poorly Placed Exhaust Fans
   • An extractor fan should be placed directly above the shower to capture steam immediately.
   • If the fan is installed elsewhere (e.g., above the toilet), moist air spreads and condenses on walls before being extracted.
   • A fan should have the capacity to remove the bathroom’s total air volume at least three times per hour.
2. Blocked or Disconnected Ventilation Ducts
   • If your fan isn’t effectively removing air, check if there are obstructions in the ducting.
   • A simple test: hold a piece of toilet paper up to the fan. If it doesn’t stick, your ventilation might be blocked.
   • Some homeowners discover their fans vent into the loft instead of outside—a costly mistake that worsens moisture issues.
3. Lack of Airflow to Replace Extracted Air
   • Air must flow in to replace what’s being extracted.
   • If your bathroom door is tightly sealed, it may prevent proper airflow. A small gap under the door or a louvred door can help.
   • Cross ventilation, like a vent above the door leading to another space, can assist with airflow.

Effective Fixes for a Damp Bathroom

1. Install or Upgrade Your Exhaust Fan

A high-quality extractor fan is the best defence against excess moisture. Consider:

• Inline fans for powerful, quiet ventilation.
• Centrifugal fans for bathrooms with long duct runs.
• Timer switches to keep the fan running for 10-15 minutes after a shower.

2. Improve Air Circulation

• Keep doors open after showering to allow trapped steam to escape.
• If possible, open a window to encourage natural ventilation.
• A through-wall vent close to the ceiling can provide another escape route for humid air.

3. Minimise Moisture Buildup

• Wipe down shower walls, mirrors, and surfaces after use.
• Wash bath mats, towels, and other moisture-retaining fabrics frequently.
• Reduce hot showers to under 10 minutes to limit steam production.

4. Prevent Mould and Mildew Growth

• Regularly clean surfaces prone to condensation.
• Use a mild bleach or vinegar solution to kill any mould spores before they spread.
• Keep a small, oscillating fan in the bathroom to promote airflow.
