Totally with you on ventilation—seen way too many bathrooms ruined by humidity alone. People underestimate how quickly moisture builds up. Good call on the humidity sensor switch, makes life easier and saves headaches later.
Humidity sensors are definitely underrated—installed one in my bathroom last year, and it's been a game changer. Before that, I was constantly battling peeling paint and mildew buildup, even with a decent fan. People often think a quick shower doesn't add much moisture, but it adds up surprisingly fast. Good move going proactive with the humidity switch; it's one of those small upgrades that pays off big-time down the road.
Humidity sensors do help, but honestly, proper ventilation design might be even more critical. When renovating my place, I found repositioning the exhaust fan closer to the shower made a bigger difference than any sensor could... sometimes it's about airflow, not just gadgets.
"sometimes it's about airflow, not just gadgets."
Couldn't agree more with this. When I flipped my last house, the bathroom had constant humidity issues even though the previous owner installed a fancy humidity sensor fan. Thought it was a great selling point at first, but honestly, it barely made a dent. Ended up realizing the ductwork was routed poorly—too many bends and way too long. Once I shortened the duct run and straightened it out, the difference was night and day. Sensors are cool and all, but if your ventilation setup isn't right to begin with, they're just band-aids.
As for plumbing check-ups... learned my lesson after a DIY disaster with an old pipe that burst mid-reno. Now I always get a pro to at least do an initial inspection. Saves headaches down the road, trust me.
Had a similar issue with airflow myself—thought upgrading the fan would fix everything, but nope. Turns out the vent was practically blocked by insulation. Plumbing-wise, I'm debating now... is a pro inspection always worth it even for minor renos?
