DESIGNER TIP Don't leave your grout colour to your tiler!
Our design team suggest you use Grout colour 43 Sand Stone Beige to blend with the tile or Grout colour 21 Linen to contrast with the tile.
Recommended Grout Joints - (We have assumed that your substrate has a perfectly flat and plumb surface, please check with your tiler.)
2mm grout joint. Based on this joint size, 1 bag of grout would cover 25m².
