if you want to remove the tile floor, you can do it yourself (diy). When you want to replace a tiled floor with another floor covering, you are usually faced with the task of removing the old tiles. Although it is possible to lay some types of flooring directly over the tiles, this would increase the overall thickness of the floor to an unrealistic level. Vinyl plank can usually be laid directly over tile, but if you're installing hardwood, laminate, or new tile, you usually need to remove the old tile before laying the new floor. Removing ceramic or stone floor tiles is a technically simple but laborious job. In fact, it can be a lot of work, especially with older installations. However, moving yourself can save you a lot of money as the work is labor intensive. In older traditional tile installations, the tiles are set in a solid mortar base which is usually reinforced with a steel lathe. The mortar bed is usually applied over a layer of tar paper covering the sub floor. Removing a floor like this can be a very difficult job, taking hours to break down the mortar base and laboriously cut a metal lathe to free the mortar and tile panels from the tar paper underlay. If you're dealing with this type of installation, be prepared for a long and exhausting work weekend.
The process involves a lot of hammering, forcing and cutting the metal lathe into manageable pieces. If you are installing tile over a concrete slab, you have the same difficult job ahead of you. The job is a little easier if you install the tile on a plywood or cement board backing. Thin-film adhesives became popular in the 1970s, allowing tiles to be glued directly to plywood or cement board coverings. The system quickly replaced traditional mortar bed systems. With a low profile installation, the bond between tile and flooring is relatively easy to break. It's still hard work, but you can take comfort in the fact that you're not facing a solid mortar base. Our floor tile removal example uses basic hand tools on a tiled floor laid over a plywood backing. The process is largely the same if you have cement board as your underlayment. When removing ceramic titles, it is usually best to first break the tile with a hammer or sledgehammer. Although we use hand tools, there are also power tools that can make the job easier. A hammer drill with a chisel or a rotary hammer with a spatula will get the job done faster and is highly recommended if the tile is being installed on a solid mortar base or concrete slab. Hammer drills and rotary hammers can be rented at tool rental stores or home improvement centers. However, an impact drill can wreak havoc on plywood or cement board flooring, so be prepared to do some subfloor repair work if you use this tool. Be aware that removing tiles can generate a lot of dust. 
It's a good idea to cover your workspace with a plastic tarp to protect your ventilation system and ensure dust particles don't pass through your home or office unnecessarily. Always wear a dust mask, goggles, hearing protection and heavy duty work gloves when removing tile. The hammering and gouging motions can lift shards of tile or mortar, causing serious damage to your eyes. Tile debris can also be very sharp when broken, so wear long sleeves when removing to avoid injury. Tile removal generates a lot of waste, especially with large floors. You may want to consider renting collection bins to dispose of debris.
- Prepare the workspace
Before you begin, take the time to prepare your workspace so you don't accidentally damage other objects in the room. Use a flat spudger and hammer to remove any moldings, trim, door frames, and doors that would interfere with tile removal. This prevents them from being damaged or covered in dust when removed. Use a sledgehammer sparingly. Repeated hard blows can damage the floor frame. Use only enough force to break the tile so the scraper can do the job.
- Separate the tiles with a floor scraper
Once you have removed a tile from the hammer, find a space for the scraper under the tile to lift it. The more tiles you can lift, the less you need to hammer, which will make the job smoother. Slide a scraper under the attached tile residue and away from the sub floor surface. Put on some muscle and they should come out. A flat shovel can also do the trick. 
Many floor scrapers face up or face down, so try both ways to see what works best. Using it in the right way can make this task much easier. Alternately hammer and scrape across the room to remove all tiles.
- Remove adhesive and grout
You may need to use a hammer and masonry chisel to remove thin adhesive and grout that is still stuck to the liner after tile removal. This will depend on the scope of the job and the requirements of the new floor, but in general you want to make the floor as smooth as possible after removing the tile layer. Your new floor may need a smooth underlayment, and these little tools can help you achieve that.
- Remove the Underlayment (if necessary)
Depending on the underlayment conditions and the requirements of the new floor, it may be easier to remove the existing cement board or plywood underlayment at this time. If the underlayment is badly damaged or the new floor requires a different type of underlayment, now is the time to remove and replace the old one. It's usually best to cut the carpet into manageable sections, using a circular saw to set the blade to the same thickness as the carpet. 
Once the liner is cut into sections, it can be unscrewed or lifted to remove. If you are installing new tile, an existing cement board covering can often be reused as the base for the new tile, as long as it is intact and firmly bonded to the sub floor. Alternatively, a thin layer of new cement board can be applied over the old layer to create a new base for the thin adhesive and new tile.
- Clean Up
Use a shovel and broom to remove debris. Heavy-duty contractor trash bags can be used to store debris for disposal. Check with local authorities for disposal requirements; you may need to arrange transportation of this material to a designated construction waste disposal site. Use a shop vacuum to remove any remaining dust and complete the cleanup.
