I always suggest having the same floor throughout. It gives it a more ample feeling, consistent and not disjointed. As far as the walls go for the bathrooms we become more creative with special and unique materials for each bathroom and in this case each bathroom has its own personality .

We like to recommend that the grout colour matches the tile as far as possible. This helps to create a seamless effect.

Anshu, There are lots and lots of combination possible . You may need to provide more details and pics to discuss it further like floor plan and pics. Thanks, Nitin Cornerstone Designs , Bangalore.

Hi Nandini, White would be an apt option for your space but you can do one thing, Accentuate some walls with one of the fine dark grey's while some wall can be muted to white. In that way your purpose of letting the space being minimal and open at the same time will be fulfilled. You can also try agate or antwerp blue for accentuating. regards
