Is this to be grouted? Or is the grout existing in the tile floor?
I cannot think of a product that would darken existing grout other than age.
A stain may work, and like a silicon sealer stain, but trying to go from
bright white to white would be tough.
Would putting a "new coat" of the right color grout over the old, tend to
darken the bright white to a less white?
Maybe. (rubbing in the chosen color on to the existing grout)
And if the existing grout were sealed.......then it would be hard to
penetrate that also.

I have a client with a tile grout they would like to darken from
bright white to standard white.
Which products are reccomended for this? Consumer Reports does not
have info on this.
