The classic subway design gets a twist with the Saint Paul mosaic in Tunisian Grey. This mosaic features Dolomite marble, a cool white marble with subtle and a soft veining and Tunisian Grey Limestone, a cool grey natural stone with brown, grey, and beige veining in a honed finish. This material is used as a tribute to the timeless statues, monuments, and buildings around the country. The mosaic's design consists of a traditional subway design made of Dolomite with small Tunisian Grey squares acting as a border around each piece.
