If your old ceramic tile isn't cracking, loose or otherwise breaking apart then yes you can lay new tile over old. I wouldn't sand it with sand paper because I don't believe that sand paper will do enough scarcifying to the tile. get a right angle grinder, put a diamond blade used for tile on it and run it across the top of the tile. you don't need to take the whole surface off just have a few tracks running across each tile. Then you will need a more high performance thinset. whenever I have done this in for a client I use Laticrete 254 platinum or you can use a bonding agent. This is a roll on liquid that bonds to the existing tile and is a good substrate for the thinset you'll be using. You might have to go to a store that specializes in Tile to get these items. just as the sales rep there and they will point you in the right direction. hope this helps, good luck!
Ceramic tiles are quite often used in bathroom floors, among other places due to their great ability to store heat. They provide great protection and look, and are easy to clean with a basic cleaning agent.

Probably not - bonding is not like insurance - it's a promise to pay on your behalf witht the understanding that you will immediately repay the bonding company, and this mark against you will probably be hard to overcome. Worth a try, but provide extra time for your agent.
