| Don't even consider ceramic tile over linoleum (or vinyl) sheet! The grout will crack first, and then the tile. This is particularly true of large tiles, such as 6x24". It may take longer for this to happen on a concrete slab, but it will happen.
Laying normal ceramic tile without grout will give you a floor that will be hard to clean. Most tile has rounded edges that will act like collection points for dirt, and germs of various types.
The Tile Council of America recommends 1-1/8" of solid wood subfloor plus at least 1/4" of tile backerboard.
A better choice in that situation would be a floating floor like Pergo-type laminate, or a floating engineered wood floor. Since these floors float, they are usually installed over a "soft" backing. The floating floor should also have a moisture resistant barrier under it, and vinyl would work well for that. |

| On my website at www.bobf.info I have a topic concerning installing laminate floors and also ceramic tile. I think you will find these helpful. |
