Your walls look new but the shower floor has started to develop issues with grout cracking and/or discoloration at the perimeter where the floor meets the walls.
Why is it that it's always the shower floor? Was your shower floor never built correctly and no matter what you do, there is always standing water that never reaches the drain? If that is your case, simply tile over tile and create the proper slope while doing so. It's an easy fix with the right tools and products and I can show you how it's done by a tile professional.
If you are like most who don't wipe down your walls and floor after each use, then you may start to see issues developing at the shower floor. Is the grout starting to crack at the shower floor perimeter? If you've decided to use caulk/silicone to repair those areas, you may notice how fungus and mildew has started to form resulting with black spots?
