DESIGNER TIP Don't leave your grout colour to your tiler and don't forget to select a coordinating silicone for the perfect finish.
Our design team suggest you use Grout colour 10 Dark Grey, for a natural blend to tone in with the colour of the tile.
Recommended Grout Joints - (We have assumed that your substrate has a perfectly flat and plumb surface, please check with your tiler.)
