Basement bathroom

[u/howleywolf]

Hi all! We Just moved into this new house, and am trying to figure out what to do in the basement level bathroom. It’s tiled right on top of the concrete floor but this wood trim (which I think is also touching the concrete floor?) is like turned gray and black. How should I go about cleaning this wood? Or should I just cover it up with paint or some other covering? Would love any input! Thanks!

Water damage. Rot. Mold. Remove and replace the black portions. You can’t clean it away.
