Revisions log for Answer #2177

Obviously you have a stone floor, not tile. They last forever (look at old churches). Research the cost of a stone floor and consider how much you want to demolish or replace it. Unlike my other recommendations, I would seek a reversible solution to preserve the value of the property and put up with slight differences in height if necessary.

Taste is not a consideration, and if you are sick of the floor, so be it. A combination of selectively placed stone carpets such as those from Mater, Louis de Poortere, CPRN Homood, Thibault van Renne, to name just a few are very different for inspiration.
