Flooring is by no means beneath me, but I haven’t really done anything below a shoe molding. So question for the tile high club: What would you do in the pictured situation? These are floor sections that have always felt a bit “squishy”. Today they finally popped up into the tent formation you see here.
Wait for it to settle and then add glue to keep it down? Cut it to fit?
Additional context:
I did not do this install myself, so the history is a bit of a mystery. This is installed in a full bathroom and is made of what feels like a smoothed slate material. I believe it is a composite tile.
More photos for context:
Looks like bamboo or laminate click flooring to me.
Edit: Looking at those new pics he posted though looks like you might be right. The backs look like tiles so maybe it's that tile that is printed to look like wood/bamboo. If that's the case then he can pull the tiles and lay down some tile cement and put the tiles back after cutting the door one a little so it fits.
It's really weird to not have grout if it's tiles as that would make the floor not waterproof.
