How to Get Your Bathroom Properly Ventilated
Ever notice a stale smell after a hot shower? That’s a sign your bathroom isn’t getting enough fresh air. Poor ventilation traps moisture, leads to mould, and can damage paint, tiles, and even your health. The good news is you can fix it yourself or with a quick call to a pro. Below are easy steps that work for most homes.
Pick the Right Extractor Fan
The heart of any good bathroom ventilation system is an extractor fan. Look for a fan that moves at least 1 cubic foot of air per minute (CFM) for every square foot of floor space. If your bathroom is 80 sq ft, aim for a 80 CFM fan. Modern fans are quiet, energy‑efficient, and often come with humidity sensors that turn on automatically when steam builds up.
When you shop, check the label for "airflow" and "noise level." A fan rated around 1.5 sone is usually quiet enough for a bedroom bathroom. Also, pick a model with a washable filter – it keeps dust from blowing back into the room.
Install, Clean, and Maintain Your Fan
Installation is simple if you have a ceiling access point. Turn off the electricity, remove the old cover, slide the new fan into the existing housing, and wire it according to the instructions. If you’re unsure, a qualified electrician can finish the job in under an hour.
Once the fan is in place, clean it every few months. Remove the cover, wipe away any grime, and vacuum the motor housing. A clean fan runs more efficiently, keeps noise low, and lasts longer.
Don’t forget the vent duct. It should run straight to the outside, not into an attic or crawl space. Long bends or a clogged duct reduce airflow and can cause moisture to build up inside your walls.
Besides the fan, you can boost ventilation by opening a window for a few minutes after showers. If you have a bathroom door that stays shut, consider a door sweep to let fresh air move in while still keeping water out.
Watch for signs that ventilation needs a check: lingering steam, a musty smell, or visible mould on walls or ceiling. Those clues mean the fan isn’t moving enough air, or the duct is blocked. Fix the issue promptly to avoid expensive repairs later.
Finally, remember that good ventilation saves energy. By removing humid air quickly, your heating system doesn’t have to work harder to dry out the house. That translates into lower bills and a more comfortable home.
Whether you’re renting or own your place, these steps give you control over bathroom moisture. A well‑ventilated bathroom stays fresh, looks better, and protects the rest of your home from hidden damage.
