White and green shared boys bathroom boasts serena lily dip dyed stools placed on carrera marble hex floor tiles under a window dressed in a green and white geometric roman shade lit by a nickel sconce mounted on white subway wall tiles with gray grout fixed beside a chrome framed vanity mirror.
Black and white hex tile with gray grout.
Since i did an inset cubby with the same penny hex the grey seemed like the best option.
It really makes the white hex tile pop.
For practical purposes light or even white grout is okay for a private upstairs bathroom floor that might only see sock covered or bare feet.
Then a company called l m came out with their line of acid r resistant grouts and included black and an umber brown grout to their line.
If they are you can use some different pattern size or color.
My other recommendation is to at least consider the other extreme a charcoal dark dark gray or light black or even a black grout.
Now when you go with a black tile and a white grout you are going to see that visually like with white tile and black grout things start looking a bit busier and you do make out the shapes of the tiles more so than you would if it was all tonal.
Up until the mid 80 s there were only three grouts white unsanded for wall tile and grey sanded or white sanded for floors.
