ᐅ Remove the tile floor or install parquet/vinyl flooring over it?

Hello everyone,

I raised this topic in another thread, but it seems more appropriate here. I wanted to get an idea of whether it’s feasible to install hardwood flooring over tiles (I wouldn’t do it myself, since I have no experience with this) or if the tiles need to be removed first. I have read that it is possible, but I’m wondering how the transition to the kitchen, which is tiled, or to the hallway works, and whether door trimming would need to be considered. Also, the tiles aren’t perfectly level—I haven’t measured, but there appear to be slight unevenness, and in the middle, the screed seems to have settled a bit (see photo).

What should I expect to pay per square meter (if the tile floor can stay)? I wouldn’t choose expensive hardwood; I’ve seen some nice options around 50 euros/m² (about 4.65 USD/ft²).

Also, upstairs we plan to replace the carpet with hardwood or vinyl flooring (I lean toward hardwood since it can be sanded). The carpet can be removed quite easily, but only the pile; underneath remains a layer (either adhesive or foam). Can flooring be installed over that, or does it need to be completely sanded off?

Thanks in advance and best regards,

Hubi

First of all, to answer your question, it’s important to know the condition of the existing tile floor.
If it is completely level, then
- tile over tile works using tile adhesive (done it myself)
- do not install parquet over tiles (haven’t tried it, but it would be a shame for the nice parquet if it doesn’t work because of slight unevenness or the tile joints)

I would remove the tiles. Then check how level the floor is, and if necessary, remove the remaining tile adhesive (by sanding).
If the floor is in good condition, then
- tiles can be glued directly (done it myself)
- parquet can be glued directly (done it myself)

Otherwise, use a self-leveling compound.

In our case, tile over tile would be in the hallway and entrance area, adjacent to the living room, dining room, and kitchen (where parquet is planned). If we remove the tiles, there is a height difference of about 10mm (0.4 inches). Can this be evened out with a leveling compound?
Do you think the underfloor heating underneath or the screed might get damaged?

After a delay, another floor installer came yesterday: Either remove all the old tiles including the screed completely (since the tiles were embedded in the screed) or cut out all the grout edges in the rooms and remove the hollow-sounding tiles (about 10 pieces), then prepare the floor and install the parquet.

She is completely uncertain with so many "options."

I'm not a mold expert, but for cost reasons, I would choose this option. How much ceiling height do you have in the room? You might lose about 2 cm (0.8 inches) when the parquet is installed on top.

Height is not an issue, and the doors and frames will be replaced anyway.
We don't want to make any mistakes or cut costs where we shouldn't, but also don't want to waste money unnecessarily.

Let’s see what others think, but if the floor installer suggests this option, it should be fine. I only know that tiles are much harder to remove from the screed. Also, you would need to redo part of the screed.
I initially planned to leave the tiles in place, but they came up so easily that I removed them throughout the whole house. However, these tiles were fixed with tile adhesive.

Any additional opinions? I would really appreciate it.
