The simple answer to this question is no. Walls tiles are not suitable for use on a floor. Wall tiles are produced to a specification which is deemed lower than a floor tile specification. However over recent years more and more tiles have become multi use. This means that the tile is produced to a floor tile specification, which is suitable for use on walls. At Total Tiles we clearly show if a tile is suitable for use on walls or floors or both. So if a tile is shown as suitable for use on the floor, there is no issue using it on walls.
