Large gross centipedes have been appearing inside my 1950s tub, and I assume they've been climbing up thru the very large gap (please see my below link). BTW, recently another gap was hacked into the shower tile at my other bathroom, since the pipe was leaking into the basement, and the only access, was by opening the wall.
Is there a cheap fix possible - such as contact paper, or duct tape, or anything else? I couldn't find an affordable solution on the net that's easy for me to do.
I'm mid-aged with bad arthritis & more, which is why i'd like an easy-to-do fix. Thanks!
