Our bathroom kind of sucks. Well, that's not fair, it's the whole house that kind of sucks, but the bathroom notably sucks. First of all, when I moved in, it was covered in mold. Three girls use the bathroom, and they could somehow tolerate it. I couldn't.
Not long after I eradicated most of the mold (can't do much with the stuff that was clearly painted over; thanks, Slumlords), a much-needed, working bathroom fan was finally put in. A large part of the problem was the lack of a fan, specifically, the fact that all the humidity just stayed there after a shower.
So this was what the landlord provided. As you might imagine, the Collegiate Handyman is not impressed. Instead of a gaping hole in the ceiling, an exhaust fan now 'mostly' resides there. It doesn't quite fill the gap that the old fan filled.
I also suspected those gaps on the sides were affecting the efficiency of the fan. But then again, if I know my landlord, it's likely that is the cheapest fan anyone makes. It's probably intended for a much smaller room. I'd guess a porta-potty.
A quick trip to the local hardware store got me a six-foot strip of pre-painted mdf trim. I had a few problems with getting the 45 degree angles to fit together nicely. It seems my motto is "measure once, cut a bunch of times" instead of the more tried and true "measure twice, cut once."
A little bit of white caulk fixed the joint problems. I gave it a day to dry then attached it to the ceiling with some screws.
Altogether, it took maybe an hour or two and cost just $3. I'd say it adds a nice touch to the bathroom. Hmm, I wonder if the landlords will reimburse me for it? I really doubt it. But hey, if they don't, I'll just pull it off on the final walk through and see what they say. That should be interesting.
