The approx. overall size is 63x53 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 background colour is Mexican White. The mural can be combined with other tiles from us, e.g. Mexican White or cobalt blue.  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.
