Ceramic floor tile question

I have a small half bath with existing ceramic floor tile on a concrete slab. I want to replace the existing tile with new tile. Is it always necessary to remove the existing ceramic floor tile beofre laying new ceramic floor tile? Why can't I simply lay the new tile over the old tile?

You can lay over old, but it's never recommended for various reasons:

1. If a old tile fails, your new tile could crack

2. The height of your floor will be twice as high.

Just rent a floor chisel from a big box store and get it all up. It will come up fairly quickly with this.

If you do choose to tile over tile, you will have to take a belt sander to it first, then clean thoroughly.
