Hi all, Im new to this group and need some help. I have a marble threshold

4"x5' 1"thick between the shower and bathroom floor. i have retiled and now would like to place another marble threshold the same size, on top of the marble. Will thinset work or should i use something else? the marble is pretty smooth. thanks

Yes. Make sure you use a thinset designed for marble; cheap gray stuff can bleed into the porous stone and discolor it.
