ceramic tile installation over ceramic tile.
Been reading about installing new tile over the existing tile on concrete Slab. Have seen some methods on line using primers prior to thinset and setting new tile. Using 12 by 24 over old 12 by 12. Floor elevations work out as there are two transitions to other rooms. Any one has experience doing this.

Our neighbors house did this. When they left that place sat on the market forever. All of that flooring had to be ripped out.

Other neighbors are pretty hardcore DIY guys and they scoffed at the floor being done that way.

OP, maybe it is possible. Or maybe my neighbors are snobs. Or maybe it is not worth the hassle?

re: ceramic tile installation over ceramic tile.
tile is super easy to remove so whats the problem?

rent a tile remover for $50 and after a noisy hour or two the entire house is down to smooth clean slab and you can do it right

putting tile on top of old tile is beyond lazy and ridiculous and is hack job work

It’s not always easy to remove even with the machines. I’ve encountered multiple jobs where even with a machine it takes days, not to mention dust goes literally everywhere. I also have over 1400 square ft of tile.

Do it right. Rip out the old first.

Call some floor places and get a quote if you don't want to tackle the job yourself.

Yea definitely not that easy to remove tile. The machine makes it easier, but usually an all day affair for a single room to get things to a smooth thinset free surface. Like all things... a good prep is key.

re: ceramic tile installation over ceramic tile.
WOW

Beware: There's a whole lot of good and wrong in this thread. From simple opinion, to presumed facts, to sometimes generalization.

IMO: When it comes to a concrete slab, every job is different and will largely depend on the condition of the previous tile. Of what's there. From how well it's adhered, to how flat it was previously installed, to what height/step-up you have or can live with . As well as how intact (cracked) the slab is, because this might involve putting down a crack isolation membrane.

And it can definitely be done successfully both ways... as long as yours is a proper candidate.

re: ceramic tile installation over ceramic tile.
How do you deal with door jambs and air gaps under the doors when you add another layer of tile

re: ceramic tile installation over ceramic tile.
Jams get cut... with doors it varies, depending on direct of pull (in-out) and if interior or exterior.

(eta:) The threshold is the biggie in this equation and usually replaced.

re: ceramic tile installation over ceramic tile.
Thanks for all the input. I have seen how hard it is to remove all the thinnest from slab after the tile is gone. Yes its easy to remove the ceramic really just a roto hammer with a wide flex blade. But its is the thin set. I was really hoping for info from someone that has done it. Not lazy just know what the demo will be like not to mention the dust and time. Mapai and other companies offer primer for tile on tile so I know it can be done and the doors and the jambs aren't an issue except for two pocket doors.As I said the differences now between the adjacent elevations the wood floors are higher than existing tile so that will negate.

Rent the little ride on machine that looks like a tiny bulldozer and it rips that old shite right up.

re: ceramic tile installation over ceramic tile.
20 years flooring experience ( mostly tile and stone but also wood) If you insist on going back with tile, remove old tile, skim coat to level out the left over thinset and them re-tile. I would personally go over the tile with a Luxury vinyl floor. Acid wash existing floor, skim coat to level out the grout lines and install vinyl.
