Alright, folks—let’s talk about something nobody’s excited to talk about but everybody needs: bathroom ventilation. If you’re planning a bathroom renovation in Sacramento, you’ve got to get this part right. Because all the tile, paint, and pretty mirrors in the world won’t save your space from mold, mildew, or that mysterious post-shower fog that never quite goes away.
Here’s your no-nonsense, step-by-step guide to proper bathroom ventilation that’s up to code, energy-efficient, and built to last.
Step 1: Choose the Right Fan (No, Not All Fans Are Equal)
Pick a fan based on the size of your bathroom. Look for the CFM (cubic feet per minute) rating.
- 50–80 CFM for small bathrooms
- 100–150 CFM for larger or master bathrooms
Mike’s Tip: Always go slightly higher if you’re unsure. Better airflow beats borderline any day.
Step 2: Vent It Outside—Not Into the Attic
This is non-negotiable. Never vent a bathroom fan into your attic space—it just sends moisture into a new area that can rot insulation and framing.
Run ductwork to an exterior vent—through the roof, soffit, or sidewall. And make sure it’s sealed properly with a backdraft damper.
Step 3: Use the Quiet Test
Look for fans with a sone rating (sound level). The lower the sone, the quieter the fan.
- 1.0 or less is whisper-quiet
- 2.0–3.0 is average
Bonus: Some newer models include built-in humidity sensors or timers. Smart and quiet.
Step 4: Seal and Insulate the Ductwork
Especially important in Sacramento, where temperature swings happen. Poorly sealed ductwork means condensation—and condensation means mold.
Use foil tape (not duct tape) and insulate the ducts to avoid moisture buildup.
Step 5: Run the Fan… Even After You Shower
Ventilation isn’t just about the minutes you’re in the bathroom. Run the fan for 15–20 minutes after a shower to clear out lingering humidity.
Install a timer switch so you don’t forget. Set it, walk away, and let the fan finish the job.
Final Word
If you’re investing in a bathroom renovation in Sacramento, don’t skip this step. Proper ventilation protects your materials, your health, and the lifespan of your renovation.
Because like I always say—do it right, or do it again. And who’s got time (or budget) for that?
