Ventilation in new builds—are we overlooking something important?

Had something similar happen in our bathroom—sensor was right next to the shower, seemed logical at first. But every hot shower triggered the fan nonstop. Moved it outside the immediate steam zone, problem solved. Definitely underestimated how sensitive placement can be...

Yeah, placement is way more critical than most people realize. When we renovated our master bath, I initially thought putting the humidity sensor near the shower made perfect sense—catch the steam right at the source, right? But just like you, it ended up running constantly, even after quick showers. After some trial and error (and a bit of frustration), I moved it closer to the door area, away from direct steam exposure. Made a huge difference.

Honestly, builders and even some electricians don't always think through these small details. They're focused on code compliance and aesthetics, but practical functionality sometimes slips through the cracks. It's worth taking the extra time to test sensor locations before finalizing installation—saves headaches down the road.

Yeah, exactly. When we built our place, the electrician put the fan switch right next to the light switch—seemed logical at first, but guests kept turning on the fan instead of the lights. Little things matter more than you'd think...

That's a good example of how small oversights can become daily annoyances. But honestly, switch placement is just the tip of the iceberg. I've seen plenty of new builds where bathroom exhaust fans vent straight into the attic instead of outside—talk about moisture and mold issues waiting to happen. Makes me wonder, are builders even checking ventilation paths thoroughly during inspections, or is it mostly just box-ticking these days?

This hits home for me... When we moved into our first house last year, I noticed condensation spots forming on the attic ceiling. Turns out, same issue—the fan vented straight up there. Makes me wonder how common this oversight really is?
