From the picture, and I’m sorry to say this, but to me the darker grout seems to have a dirty/mildew look to it. Like you try to scrub it and it just looks like it won’t come clean.

I don't care for any of those. I actually like how the tile really shows off where you don't have it grouted. That look would require an even darker grout.

You could also try white - go the opposite of what you are thinking. You might be surprised!

@Debbi, I can’t do white, it’s not practical for me. It would make me neurotic with constant cleaning.

Mapei Frost like tile on wall

@vjs12, can’t do frost. Already tried it and more washed out looking than the dove gray.

I have Warm Gray in my own shower and it's not brown.

(yes, it's on the mosaic tile too. it's a warmer, off whtie that leans on the gray side. a warm gray. not the least bit brown)

you have to wait for the grout to fully dry. the colors will lighten. I still think it's your best choice.

not many other cooler choices from Mapei. (the others are more yellow)
