i've just got done "doing-it-myself". my bathroom door sticks a bit because the building has shifted (i presume) and today the handle broke off when i was pushing it open. not being very well versed in these things i went to the hardware store thinking i could just buy a new handle, but it turns out you have to buy a complete kit, and naturally there are all sorts of sizes with difference spaces between the holes (to make things even simpler). since i hadn't measured i just bought the only model they had with a built-in turn lock and hoped for the best. it wasn't *quite* the perfect fit, and also apparently the two pieces i got aren't quite identical
but since they're made out of plastic with a little determination i managed to get it attached to the door and the handle and lock lined up fine. i could only get one screw in, the bottom holes were a few millimeters off, but as far as i'm concerned that's good enough. then i fixed the shower holder thingy too ; the screw holding the bottom of the bar was coming loose so i pried out the plastic... cheville (no idea what you call those : little plastic things you put in the wall to make the screws bite in better) and put a new one in. the bar itself seems still a bit loose between the two ends but there's nothing i can do about that. so i'm calling that good enough as well. seems like a good days' work to me.
