We just finished building a new house with a tile shower in the master bathroom. The grout for the walls and floor are both charcoal. When the floor grout was installed, it was a much lighter gray than than the charcoal grout on the walls. I confirmed that the correct charcoal color was used. Since the installation, the grout has continued to whiten, which I attribute to efflorescence. Since the grout on the walls turned out fine, I'm assuming this is not an installation issue, rather an issue with the minerals in our water. My plan for fixing is this:
-Clean grout
-stain grout with "Aqua Mix Grout Colorant"
-seal grout
-install some sort of filter to remove mineral from water and prevent future issues
Can anyone confirm whether this is an effective plan? And if so, what kind of filter can I install?
Thank you in advance for any help. It's very frustrating to have a brand new shower that looks so awful.
