I have tiles over tiles before and it turned out great. You will be surprised how often it done. If you are tiling over tiles on the floor you may need to trim the bottom of your doors.
If you are tiling a wall and the tiles don't go all the way to the ceiling. Make the last top row slightly higher than the old tiles and back fill with grout.
Make sure when you buy the adhesive you let them know you are tiling over tile so they can sell you the correct adhesive.

With no offense to you or others who answer, I'd have to agree with my2cents. I've installed thousands of sq. ft. of tile in my long career, and removed as much.
The issue, especially for one IN THE TRADES isn't so much that it can't be done, but personally I'd NEVER put my name on a "TILE OVER"
One of the most obvious, initial problems is increasing the height of the existing floor by another 1/2 inch, and what that will involve.
Without knowing at all the area you're talking about, I cannot imagine GRINDING the surface of even a small room filled with tile floor, then having to clean that up, then substrate the entire floor area, then thinset, then install.
If having a raised area isn't an issue why not just lay a new substrate, IE: Concrete backer board over the old tile, then do your thing with thinset mortar and add the tile. The transition areas will still be a problem no matter.
Why is it that so many think tile removal is so wrong?
Anyway I applaud my2cents. As a contractor I would refuse the job, if asked, as stated you want it done.

I just faced this problem when re-tiling my foyer and hallway. I talked with five tiling contractors and all said that it could be done if you could get the thinset to stick to the covered tiles. The consensus was that roughening up the tiles and using an acrylic-modified thinset would do the trick. Unfortunately, none was wiling to try and warranty the work. I ended up trying it myself. Roughening up the tiles sounds easy enough but ceramic tiles are very, very hard. The only means that I found successful was a angle grinder and diamond wheel. It was a huge mess and very destructive. I ended up jack-hammering out all of the old tile and started over. I know that laying new tiles over old tiles is done all the time but it may end cracking loose and that you just don't want. I had another idea that may work for you. There is a construction adhesive meant for tiles. I've tested it when we re-faced our fireplace and it holds like mad. It should work for your floor.

That's probably not a good idea. You need to remove the existing tiles before you put new ones. You can do this a few different ways... if you are doing a floor, I recommend a product sold at the major stores called a "Mutt". It is a handled (like a broom, but thicker) item with a large flat blade that you use to break the old tiles out, the first one is the hardest so you may need to break it out with a hammer. Use eye protection!

I'd never seen this done and we've been in interior design for 30 years. But, my neighbor's contractor just did it in their bathroom. You have to grind down all of the ceramic tile so that they are exactly level. Put down a layer of thin set, place and grout the tile in place.

Hi,
Tiling over tile is a very common thing to do. One of my friends has been tiling for 20 years and he does it all the time. If you try to remove the old tiles you will end up making so much work for yourself, in trying to get the old adhesive off.

You should not do this unless the bottom layer is in good condition, meaning that there are no loose tile. Remember that if the lower layer adhesive fails, the whole floor fails.

Cant do it. The old tile must be torn up.

Don't even try it, remove the old ones first!
