1) Study the kind of floor you have - or rather, your subfloor. Knowing the kind of subfloor you'll be setting your ceramic tiles over is important. There are three main types of floors (or, subfloors), that you might encounter, when starting on your ceramic tile installation:
a. A concrete floor - Concrete floors are excellent for tiling but it's important that you first rid the concrete of any debris, grease and dirt before tiling. All the cracks and holes need to be repaired and filled in before your ceramic tile installation can start. Once your start working on your project, each of your ceramic individual tiles will be bonded directly to the concrete floor. If the cracks widen, this will affect your tiles, as well. Some cracks may even be that large that it would be best to replace the larger sections of your concrete floor rather than patching up all the cracks. If you have a lot of large cracks, especially ones that run up the wall, consult a specialist before your start working on your tiling project.
b. The plywood subfloor. Second floor rooms are mostly in plywood. Because you will be putting ceramic tiles over wood, your plywoord subfloor has to be structurally sound and capable of supporting your ceramic tile installation. Your plywood floor has to be at least 1 1/8 inch thick, and supported by an equally strong underlayment beneath it. Ceramic tiles are heavy and would need a subfloor that can support their combined weight. And they will become dislodged, or even break. Otherwise, it would be unwise to do a ceramic tile installation on wood.
c. An existing ceramic tile floor. Ceramic tile floors would more often than not, require the new room occupant to remodel. There are two options for remodeling an existing tile floor: One, leave the tile floor in place and work your ceramic tile installation directly over it; or two, remove the old tiles. If the current tile floor is set over a mortar bed, the easiest way to remove them would be to use a large flat-bladed chisel and just hammer away. Be sure to keep yourself protected.
2) Get an estimate of the cost of tiling by measuring the length and width of the floor area. When you go window-shopping, make sure to bring your measurements and discuss it with your hardware or home center specialists. Those measurements will help you a lot in estimating how much ceramic floor tiles you need to buy. It will also help you estimate how much cement and grout, and the tools you'll need for your ceramic tile installation.

b. Window-shop for your tiles. After you've made the estimates for the floor space that needs to be tiled, window-shop for your ceramic tiles.
