We are going with Daltile 0100 3x6 subway tile for our tub/shower and Daltile octagon + dot (white on white) tile for the floors. It's a tiny bathroom. Both tiles are a softer white, not bright/stark. I'm considering Mapei's Eggshell for the walls (1/16th) and Warm Gray for the floors (1/8th). I wanted to go with a light gray grout on the walls which would be easier to keep it looking cleaner (Warm Gray is too dark), but the only option with Mapei is Frost which seems cooler, maybe? I thought slightly warmer grout would be better with the Daltile 0100. (If I went with Frost on walls, I would also go with Frost on floor.)

How would you describe Mapei Frost? Does it work with slightly creamier/warmer-leaning white tile?
