I live in a 1928 house built from a Sears kit, and while the landlady renovated the kitchen, the bathroom seems pretty close to original. So it’s got a shower conversion that consists of hanging some metal racks from the ceiling to hold a shower curtain around the clawfoot tub.

Yesterday a screw fell from somewhere into my shower, matching a previous screw that had mysteriously appeared in the bottom of the tub.

I cannot see any empty screwholes on the shower curtain rack, but I am concerned.
