(I know this has come up here before but didn’t see anyone who posted their end result). They’ve completed grouting the floor and it’s lighter than I had hoped. I wanted to have a more seamless look. The installers want nothing to do with changing it so my options are 1) just go with the light grout all over 2) have them do a darker grout on the walls and try to use a grout colorant or 3) pay to have the floor grout removed and redone. The back & shower walls get less light so those tiles appear even a bit darker than the floor, so the grout I had selected will stand out even more. It’s Prism cement grout, if that’s helpful. Tile guys return tomorrow to finish. Any advice?
