i just moved into a new house and they had peel and stick caulking on the bathtub that wqs starting to peel away so i knew i wanted to redo it with actual caulking. well i peeled up the old stuff and found these wooden pieces that seem to be holding up? the walls of the shower?? except they don't go all the way out to the outer edge of the tub.
do i need to do anything about this? having wood sealed behind caulking seems like a recipe for mold, plus am i even able to caulk such a huge gap?
(side note, would also love recommendations on how to clean up the peel and stick caulking)
