These prices reflect the total cost for the job, material AND installation,
and are fairly standard. Both products are usually installed by competent
setters in a similar fashion, that is thinset mortar over a suitable
substrate. Ceramic tiles may however, and are commonly set using mastic
instead of mortar. The installation of marble is often easier for the
tilesetter, as the tiles are often a full 12" square, thus many fewer pieces
to work with, hence many fewer cuts.



Oh shut the **** up you top-posting imbecile. Pros do not, nor
recommend using tile mastic for floor tile installation and if marble is
set properly with a tight joint, over a 'fresh' mortar bed, using pure
cement and beat in it's far more work than slapping floor tile down over
a slab or backerboard using a standard 3/16" joint.

Your advice sucks.
