El-cheapo all-in-one-piece shower ("box"/cubicle, floor, door, etc)
Got screwdriver to undo the drain-cover -- way too shallow for my (actually, *any*) screwdriver; seems that it's yet another el-fako (like that bathroom air-vent/blower I mentioned once, that simply blew it right back out into the room!).
That is, those indentations that *looked* like the heads of screws, wereen't. Were simply indentations!
How to snake it?
Thanks,
David
