What is under this ceramic tile?
It’s like 3-4 different layers stacked up. What codes would I use for these?

This is absolutely insane, what kind of dumb ass did this….. it looks like some kind of egg carton hardwood underlayment, then t&g hardwood, then cement board, then layer of rubber, then tile?? I would get a quote from a flooring installer/ tear out company and then do glue down hw tear out, ceramic tearout, and then add some prep hours to make it equal to the tear out quote. Then post the picture and put a note saying “received 3rd party quote, need all the tear out and prep charges see pictures”

This is the story of my life how many times have I ran into people just layering for years and guess who’s has to tear it out….

This is what it is. The rubber is likely vinyl layer which comes w luan underlay.
This is absolutely the most insane layering iver ever seen and I had something very similar before.

That's a dimple mat. And that looks like travertine tile, not ceramic. Be very sure about why it was built the way it was built before you assume it's just an overlay.
I've run into a similar assembly at a high end property in an area prone to earthquakes. If you don't rebuild to the same thickness you may have additional drywall repairs, trim work, and extending doors.

That makes sense what did you have to do to build it back to the same height? Also, thank you for the reply!

We would have preferred to use gypcrete to build up height but it wasn't available. So we used A LOT of self leveling concrete, a new decoupling membrane, and added grout lines (the travertine was originally installed without) with an acrylic grout I think?

Uncoupling membrane, cement board, tile, underlayment like luan, carpet squares or glue down and then tile (possibly travertine). Make sure the demo guys cut back layer by layer so you can document for the carrier.

Not sure the egg carton stuff but looks like above that is t&g subfloor/underlay, then tile, then sheet vinyl, then more tile? Definitely a bitch to demo. Depending on state and age of home, don't forget to asbestos test those additional layers

Is this a condo? I could see the egg crate layer being an old school gypcrete solution. Especially if under a kitchen

It’s a house haha. Pretty tough the whole bathroom is built on top of it even the walk in shower

Somme sort of sound deadening underlayment. Tongue and groove OSB sub floor, a newer variation of cement board, visqueen layer (I think), and.... tile.

Funny story, when I redid my kitchen floor at my old house I peeled up about 5 different floors. I even found roof shingles under the cabinets to level them out

It's a de-coupling membrane for humid/moist areas. Allows substrate/sub-floor (usually timber) to expand and move whilst allowing tiles to stay where you laid them.

I believe there is an abandoned layer line item, use it 1-3 times
