Decorate your fireplace with Mosaics
Mosaics are one of the most popular choices for decorative tiles or a feature. Small tiles, often elongated rectanges, are laid together to create a larger effect. Confining this block of gorgeous detail around your fireplace establishes a dominating feature for a high visual impact in your living space.
If your fireplace's personality is a bit more mellow and not an attention seeker, why not try large format stone design tiles in different shades of grey to add something extra to a neutral colour palette. This will also visually increase scale and if your tile feature wraps around your fireplace and reaches to the ceiling it will accentuate the height of your room.
