Is it possible to fit new tiles on an old tiled floor?
Yes it definitely is possible to fit new tiles on top of an old tiled floor providing that none of the underneath tiles are loose or uneven. However it is not advisable as the cost would be high and you would be reducing the headroom (height between the floor and the ceiling). However if you still want to go ahead, then see that the existing surface provides a good ‘grip’. If the existing flooring is of glazed tiles then they have to be roughened to give a good grip for the new floor.There are some other factors also that you have to take into consideration before deciding to fit new tiles on an old tiled floor. The most important being the finished floor level. You need to allow for the thickness of the tiles that you are laying, plus approximately 6-12 mm for the cement slurry/adhesive, depending on the type of flooring to be laid. Once this thickness is added on top of your existing floor, will you still be able to open doors.
