The size marble subway comes in
Marble is sawn in metric, so the sizes arrive as conversions. 2 3/4x5 1/2 is 70 by 140 millimetres written in inches, and it is the size most of this range is cut to. A 3x6 in marble exists but it is the exception.
The consequence is practical. A wall set out for the ceramic 3x6 does not give the same number of courses in 2 3/4x5 1/2, so the height a band lands at changes and so does where the cut falls at the top. It is worth reading the size field, because the word subway describes a proportion and not a measurement.
The longer proportions
Behind the small format sit 3x12 and 4x12, and those are not subway tiles in the original sense at all. A 3x12 is four times as long as it is tall, which reads as a plank rather than as a brick.
The difference matters on a wall. A 1 to 2 rectangle in a running bond gives the dense brick pattern people picture when they say subway; a 1 to 4 rectangle gives long horizontal lines that stretch a wall sideways. The same marble in the two formats is two different rooms.
Honed is the default here
Most of this range is honed, with a small polished group and one textured piece. That is the reverse of a ceramic subway, which is glossy almost by definition, and it comes down to what each material is being asked to do.
A glazed ceramic subway is a glass face and a reflection is free. On marble the polish is the stone's own surface refined, and a honed face gives the same stone with the reflection taken out, which is the quieter and the more forgiving of the two at close range.
The marbles in this range
Carrara and Calacatta carry the white end, Alpina is the pale quiet white, Bardiglio and Silver are the grays, and Abyssal and Flecked are the darker and more marked faces. Patchwork is a mixed face, not one stone.
What separates those names in the quarried stone is set out on the marble tile page. On a subway format the practical difference is how much figure a small piece can hold: a Calacatta at 2 3/4x5 1/2 shows one vein or none, where a Carrara shows its fine gray movement on almost every piece.
Where a marble subway goes
A kitchen backsplash and a bathroom wall take almost all of it. Both are read from two or three feet, which is the distance at which a stone face is worth paying for and a printed one starts to show.
The marble tile backsplash page covers the band itself: how a backsplash height divides, what the grout does, and how a tile backsplash compares with a slab.
Thickness and the edge
The range sits at 3/8 inch, which is the standard for marble field tile and the figure that matters where the subway meets something else: a trim piece, a window reveal, or a run of a different tile.
A marble subway is sawn square on all four edges. A ceramic subway is frequently pressed with a slight bevel, which is what gives a ceramic wall its shadow lines, so the same pattern in the two materials reads flatter in marble and more defined in ceramic.
