Right, so you’re asking about bathroom fans—size and noise, yeah?
Honestly, I didn’t give it much thought until last winter, when my mate’s place in Hackney ended up with mould creeping up the corner near the shower. Smelled like damp socks, no joke. And the fan they had? Sounded like a hoover stuck in a cupboard—dreadful thing. You’d switch it on and practically have to shout over it just to hear yourself think!
So, size first. It’s not just about the fan itself, really—it’s about the room. My tiny loo in my old flat near Brick Lane? Could barely fit a person and a towel rail. I made the classic blunder—got a fan rated for a massive bathroom because the chap at the DIY shop said “bigger is better.” What a load of nonsense. The thing sucked so much air it felt like a wind tunnel! Ended up with the door rattling every time I turned it on. Proper annoying.
You want a fan that moves enough air to actually clear steam—not just shuffle it about. There’s a rough rule: for a standard bathroom, aim for at least 1 CFM per square foot. My current place’s bath is about 50 square feet, so I went for a 60 CFM model. Works a treat after a long hot shower—mirror clears in under a minute. But if you’ve got a fancy wet room or one of those rainforest-style showers? You might need something beefier. Saw a gorgeous one in a showroom in Chelsea last spring—utterly silent, but shifted air like a gentle breeze. Lovely bit of kit.
Now, noise. Oh, this is where people go wrong. You don’t want a fan that sounds like a jet taking off every time you flick the switch. My first fan? I swear it was louder than the Northern line at rush hour. You’d avoid using it just to keep the peace! These days, I look for something rated below 2 sones—that’s the noise measurement they use. My current one hums at about 1.2 sones. It’s there, you can hear it if you listen, but it’s more like a faint fridge buzz. Doesn’t interrupt a podcast or a phone call. Bliss.
Mind you, I stayed at a boutique hotel in Edinburgh last autumn—beautiful place, but the bathroom fan was practically whispering. Too quiet, honestly. Couldn’t tell if it was even on, and the mirror stayed fogged for ages. There’s a balance, you know? You want it noticeable enough to know it’s working, but not so loud it makes you want to rip it off the ceiling.
And installation—don’t get me started. If it’s not vented properly to the outside, you’re just blowing damp air into the attic. Saw that in a rental in Manchester once. Landlord had “fitted it himself.” Ended up with condensation stains on the ceiling by Christmas. Had to argue for months to get it sorted.
At the end of the day, it’s one of those things you don’t think about until it’s wrong. Get the size right for your space—don’t just guess or go for the cheapest. And for heaven’s sake, test the noise level if you can. Some shops have display models you can listen to. Or read reviews from folks who’ve actually lived with the thing. There’s nothing worse than a noisy fan ruining a perfectly peaceful soak in the tub.
Oh—and a little tip? If you’re after discretion, look for fans with built-in humidity sensors. Mine kicks on automatically when the steam builds up, and turns itself off after 20 minutes. No buttons, no remembering. Just does its job quietly in the background.
Anyway, hope that helps a bit. It’s not the most thrilling topic, but get it wrong and you’ll notice every single day. Trust me on that.
