Is the mortar used in holding your tiles in place pulling off? Have any of your bathroom tiles fallen off yet? If this is the case, then you may need to repair the bath tile before all of them come off. If you don’t repair them in time, water can get underneath the tile and cause more tiles to come off or ooze off a putrid smell. If you don’t repair the tile immediately it starts coming off, the small repair task may turn out to become an expensive repair.
