The approx. overall size is 55x77 cm (not including grout gaps). It is normally recommended to lay the tiles with approx. 3 - 4 mm grout between adjacent tiles (the overall size of the mural is then slightly larger). The mural can be combined with other tiles from us, e.g. Mexican White or "Mango" or "Brown, washed glaze". The mural is for indoors use only and is laid just like any other tiles. The mural is a unique item - please do not order more than one. Please call if you have any questions.
