It depends on the suitability of the subfloor and on the thickness of the medallion in relation to the wood flooring.

If you have particle board as a subfloor then no you cannot install a tile medallion. It has to be OSB or plywood with an underlayment rating, CDX is not and has only a sheathing rating. It must be a minimum of 5/8" with joists spaced at 16" on center.

You will need a sheet of 1/4" cement board as underlayment so check to make sure the board and the medallion combined are not thicker than the wood flooring.

You can have a solid marble or mosaic medallion installed in hard wood flooring very easily. There are lots of different types to choose from. The best fitting are medallions with a thin alumium backing this allows for a level,and soild installation. There are many to view on below site. HH
