Think you should listen to the tilers...
Theres a reason why its called a wall tile.....its ment to go on the wall not the floor.
Floor tiles are graded 1to 5 grade 4 and 5 are suitable for most rooms in your house...grade 2 and 3 light traffic areas only ie bathrooms or bedrooms....I doubt your wall tiles are a grade 1 if that....infact I dont even think they grade wall tiles....still its your money so good luck..
