This subway, or metro tile as it became affectionately known in the 1900's, is the correct size of 75 x 150 mm and has a black, matt surface. These tiles are iconic of the subways of New York and London throughout the years and have remained in our minds until now, when they make their return. Use these tiles on the kitchen or bathroom wall to create a classical or retro modern look when combined with dark coloured grout. The matt look gives a natural touch to the subway look. It requires 88 of these subway tiles in order to cover an area of one square meter. For best application use Progrip mosaic adhesive in the colour of your choosing.
