For your bathroom remodel in Santa Clara, ventilation is one area where going overboard saves money.
If I’ve said it once, I’ve said it a thousand times….. When it comes to bathroom exhaust fans, bigger is better.
I’ve read many times a rule of thumb that your bathroom exhaust fan should be sized for 4 complete air changes per hour. That means it will recycle the air in that bathroom every 15 minutes.
Per me, that’s too long.
We’ve seen over and over the damage small amounts of water cause over long periods of time. The only effective way to combat this problem is to not allow small amount of water to sit very long.
This is where bathroom ventilation comes in.
I recommend the exhaust fan you install during your bathroom remodel be strong enough to change the air every 4 minutes (and yes that is an arbitrary number, but a target is needed).
This means in a standard 8x5x8 hall bathroom, which is 320 cubic feet, you want an exhaust fan of at least 80 CFM which is easily doable.
If your bathroom is four times that size, per my rule you need a fan that is 4 times more powerful, or 320 CFM, and since they don’t make them that powerful, you’ll need to back down to a 300 CFM fan which is available.
Yes you will pay extra for the fan (maybe $170 vs $100) and you will pay a very little bit extra every month for electricity, but those expenses avoid major wood rot repair down the road, it was well worth it.
