May I suggest contacting the interior designer to request information on the tiles?

Depends on height of the ceiling,and size of your room. ceilings up to 2700 tile to ceiling ( replace ceiling, it is not a good look new bathroom with old ceiling, unless featured ceiling, you need to remove cornice, Tile all walls to ceiling, add new cornice for professional look ) Have you thought of feature wall behind basins, same as floor tiles ?

Hello again, Definitely not too warm. I am not entirely sure what paint colour you are thinking of but as pointed out - easier to adjust paint rather than the other way around. If the tiles were really grey and the walls were that tone as well, it would be a very flat, souless look - the slight touch of warmth in the tiles is a good thing and honestly being so neutral your options are huge with colour of walls, particularly if you are intending to use this tile throughout. May I suggest you choose a paint colour and then use different depths of the same colour depending on sunlight, dark corners, more impact in certain areas etc to create the interest. Be wary when you have such a neutral, albeit very tasteful tile, it may be wise to adjust the paint in this way to lift the level of interest. Take a look at the following colours - Resene House White and Resene Concrete as starters - very unobtrusive. You could always go for a hit of charcoal in areas too. Avoid any "feature" walls - do the whole room - nothing wrong with strong, dark colour, even in small rooms - think powder room or laundry if you are not brave enough to do an entire, larger room. I am also assuming you will be introducing plenty of white trim on skirting boards etc - for what it is worth, my go to white is nearly always Resene Alabaster. Loving the sound of the carrara - such a classic. Hope that helps :)
