Hi - the white "seam" (sorry not sure of technical term) which acts as the joint between the floor tiles and and the marble bench is sort of rotting and discoloring. Is this a simple fix? Hit it with some bleach since it might be mold? My wife is on my case :)http://bit.ly/2Whl5Lp via /r/DIY http://bit.ly/2X4NS3i
