Went to homedepot to see if they have additional. There was none. I asked store associates about these tiles and got informed that they seldom stock as demand is not that high and explained the reason which is pretty much in line with what folks posted here: those are pretty cheap item and not known for its reliability, tend to peel off. For my case, may be I will complete it and see how long it last and if it starts falling off, I will think about something better.Hey, can we get some pictures of the whole thing completed? Any update on leak/smells, of the mold variety that is.
