Please pay attention to your grout choice when selecting tiles for your project - it is an important part of the overall effect.
Grout is what is used to fill in and seal the gaps between your tiles when they are installed. It is generally made from a mixture of water, cement and sand with some additives and polymers.
Selecting the right colour grout for your intended finished project is very important because the grout is actually a significant part of the overall aesthetic, particularly with smaller sized tiles.
You either want to select a grout colour that blends in with your tiles, to make the grout joints less noticeable, or select a contrasting colour to make the tile shape, laying pattern and grout more prominent.
Usually with large sized tiles (600x600mm or larger) you will probably want to minimise the appearance of the grout and we recommend choosing one shade lighter or darker than the main colour of your tile. Essentially, you want the grout joint to blend into the background of the finished project.
For smaller sized tiles, you often want to show off the colour, size, shape or installation pattern and in that case you will want a contrasting grout colour.
There is no right or wrong in terms of the grout colour to choose, the point is to make sure you think about it and make the decision for how you want the finished tiles to look.
The same rule applies with small tiles as to larger tiles, if you want the tile and grout to blend together and create an effect of one surface, then select a grout colour that matches the tiles. If you want to really define the tile, select a contrasting colour, perhaps a dark grey for a white tile or even go bold and use a colour. There are many different grout colours available.
The following images all show a white brick shape tile installed with different grout colours, from matching, to a neutral light grey (which is easier for cleaning) to a contrasted dark grey. You can see how the grout colour significantly changes the finished effect.
