The air bequeath smell (often!) sweeter, paint testament last yearner, and mold will uprise slower — or not at complete. Now are you ready for a bathroom exhaust fan installation?
A lavatory exhaust fan is an inexpensive raise that packs a value punch. The shoe-box-size fan clears obnoxious toilet odors (priceless!) and removes wet, which protects your home and health, and reduces criminal maintenance costs.

Still, many an homes don't have a bathroom devotee. Although the fans are required by building code in many places, older homes -- pre-1960s -- didn't habitually install them. And homeowners nowadays may constitute reluctant to retrofit bathrooms with an appliance that requires venting to Snake River done attics, joists, soffits, and ultimately punctures an exterior wall up or roof.
We feel your fright, and we're here to help. Below, we break down everything you need to know well-nig selecting and installing a priv exhaust fan.
What Does a Bathroom Exhaust Fan Do?
A bathroom exhaust fan is a small, ceiling- or wall-mounted fan that pulls air from the bathroom, sends it through venting (4-inch is preferred), and deposits IT outdoorsy.

How Are Fans Rated?
Eat fans are measured by two factors found happening the fan's box:
- CFM (cubic feet per minute): Indicates the strength of the fan's draw. CFM's give notice orbit from 50 to 1,000-plus, although most bathrooms typically require fans with little than 200 CFM.
- Sone: Measures of the sound the devotee makes, typically from 0.5 (almost silent) to 4.0 (sounds suchlike a normal television) -- loud for a fan, but it does provide privacy against toilet sounds, peculiarly nice for powder suite often placed near world areas of your menage.
Most people choose a 1- or 2-sone fan -- quiet sufficiency go on your teeth from rattling, but not and so quiet that you'll forget it's on.
CFM and sone are related, because stronger fans -- with high CFMs -- normally create many noise; quieter fans -- lower sone -- often can't adequately clear beam from bigger areas.
The important affair is to pick a rooter that's right for your blank, ears, and budget.
Sizing Your Fan
The Home Ventilating Institute, which tests and certifies manufacture claims, suggests that homeowners follow these formulas when sizing a sports fan:
For bathrooms to a lesser degree 100 direct feet: Calculate your bathroom's square footage (distance x width), and pick a sports fan with at the least that number of CFMs. For example: If your bathroom is 6 feet by 8 feet, you should buy a buff that's at least 48 CFM. A 50-CFM model comes closest and is the minimum sized advisable for small bathrooms.
Size a winnow for a ginormous bathroom: If your lavatory is bigger than 100 square feet, forget near the square footage figure; instead arrogate a CFM capacity for each fixedness:
- 50 CFM -- toilet.
- 50 CFM -- bathing tub.
- 100 CFM -- jetted whirlpool tub.
- 50 CFM -- cascade.
If you have a completely tricked-out priv, you may involve at least 200 CFM of draw, which you can accomplish with individual 50-CFM fans (incomparable fan should be in separate toilet enclosure), or one big, 200-CFM fan.
How To Install Your Fan
Bathroom fan installation isn't learning ability surgery -- collect melodic line here; beat ventilate there. But IT's not for beginners either, because the project includes removing drywall, perhaps drilling through joists, certainly busting through an exterior wall or roof.
We suggest hiring an HVAC pro, who volition charge $150 to $700.
If you decide to install a fan yourself, here are some decisions you'll have to make:
Location: If you have a separate WC, put a small fan on that point. If your toilet is part of the bathroom, locate the fan between the toilet and tub/shower down.
Discharge: Exhaust flows through venting attached to the fan and out an exterior wall or roof. Ne'er vent smelly, damp air into an attic or crawl infinite, which will warp rafters and further mold growth.
The melodic theme is to run venting the shortest, straightest itinerary from the bathroom to outside. Every extra foot and bending the venting makes increases detrition and decreases air out pull down and fan efficiency.
Appropriate discharge runs up into your attic, then along or through with floor joists until it reaches the eaves. From in that respect, it can equal worn-out come out of the closet a soffit.
In some instances information technology may live more practical (and inferior expensive) to run the vent directly out a bulwark, operating theater through a volcano spate in your roof.
Threshold clearance: During installation, make a point your bathroom door has at to the lowest degree 3/4-edge in clearance from the shock, so "makeup air" tin can easy replace the sucked-out air, putting less stress on the buff.
Winnow Options
Lavatory exhaust fans seminal fluid in custom styles and colors, but to the highest degree of us would rather spend our decor budget elsewhere and will prefer an off-the-rack fan with one or more of the following options:
Fan exclusively: If you're retrofitting a small toilet that already has a cap repair, select a alkaline winnow, 50-70 CFM. Monetary value: $15 to $50.
Fan-and-light jazz band: Serious for teensy bathrooms or WCs. Choose a combo with enough wattage to sufficiently light the area, typically upwards of 60 Watts. Price: $30 to $150.
Deluxe combo: All the bells and whistles -- fan, light, heater, nightlight, timekeeper (necessary for super-quiet fans you won't remember are on), humidistat (automatically turns on fan when air wet rises). Cost: $150 to $600.
