Thickness of floor coverings

Hello everyone,

I have some questions about floor coverings and gap dimensions: We are planning to lay laminate with a thickness of 10mm + 3mm impact sound insulation everywhere upstairs except in the bathroom. In the bathroom, 10mm thick tiles will be installed, is 3mm tile adhesive sufficient? (I haven't been able to ask my tiler yet).

Downstairs, we also have 10mm tiles + 3mm adhesive and in the living room 15mm parquet + impact sound insulation, therefore the screed there is also 5mm lower than in the rest.

The problem now is the front door: If I calculate with the 13mm tile buildup, I only have 7mm left to the lower edge of the front door. I might be able to get a few more millimeters by adjusting the front door, but not much more. It would of course still be possible to have the screed ground down by another 5mm, but I would obviously like to avoid that.

And what exactly is the question now?

We only have a few millimeters for the front door as well. That works. Unfortunately, there is no room for a runner or shoe mat anymore. If the heights don’t match, then someone did not pay attention. The choice of the flooring or its thickness should already be decided before the screed. Milling the screed afterwards is a lousy and dust-producing job that should definitely be avoided if possible.

But is it a new building? As far as I know, the data for the floor coverings is requested at the beginning or during the shell construction, so that the screed can be planned accordingly. Tiles are planned as standard in the hallway, so it should fit with the front door. I wouldn't worry about a difference of one or two millimeters on the upper floor.

Do me a favor and plan something more sustainable than laminate there. Laminate would only be an option for me, if at all, in a rental apartment, but never in a home you own.

And what exactly is the question now?

That’s what you get when you write something like that alongside work. Once the question about the tile adhesive, whether that’s enough and whether 7-8mm is enough for the front door.

But this is a new building, right? As far as I know, the data for the floor coverings is requested at the beginning or during the shell construction phase, so that the screed can be planned accordingly.

Yes, it’s a new build, but we only had the shell construction done and also commissioned the screed layer ourselves. The screed layer planned 20mm under the underside of the door and also implemented it that way. Only the door was not level, and as luck would have it, he hit exactly the spot where the door has the greatest distance from the floor. Ultimately, a chain of unfortunate circumstances.

The screed layer has also already agreed to grind down the screed, but I would prefer to avoid that for the reasons Koempy mentioned. Hence the question whether the adhesive thickness and the gap under the front door are sufficient.

I was waiting for that comment from you :P. For the upper floor we want a cheap option because of the kids, so it’s not a big deal if there are scratches, hence laminate. Or do you have a comparably cheap and durable tip? We’re still quite inexperienced when it comes to alternative products?

Disadvantage of dark cork: it fades, and due to its elasticity, you can see furniture marks more clearly. So if cork, then light and furniture with gliders, and everything will be fine.

Anyway, rather light coverings are preferred, except in the kitchen. But if I see that correctly, cork is less suitable for the hallway, right? We would like to install a uniform covering in all three rooms and the hallway and only have a transition to a different flooring in the bathroom.
