Supply line for kitchen island with induction and 3 sockets

Hello,

We want to install a kitchen with an island in our new house. What is the best way to run the supply line to the kitchen island? The problem is that the connection is installed on the opposite wall in the room. Additionally, the floor structure including underfloor heating is already in place. The screed on the underfloor heating is still missing.

How do I get power to my kitchen island?

I also have a general question. Is it generally possible to lay cables along the wall in the screed? I would like to install a home network and still need to lay a few CAT7 cables for that.

Best regards

In addition, the floor structure including underfloor heating is already in place. The screed on top of the underfloor heating is still missing.

Ideally: partially and temporarily remove the underfloor heating, lay the cables in the insulation, close the insulation neatly, add the foil, heating, and screed. What is the entire structure of the ceiling and floor? What is below the ceiling?

Cooking on the island IMHO also requires a supply line for a range hood. I would lay this as well, even if you initially want to install a range hood in the island or even plan completely without one.

Is it generally possible to lay cables along the wall in the screed?

Not according to the rules. Either under the screed in the insulation layer with distance from the wall or in the raw ceiling or ... You could later install suitable skirting boards/channels. Home network cables belong in empty conduits if you lay them in the floor structure or "inside the plaster."

Extractor hood comes from the ceiling. Actually, I don’t want to reopen the underfloor heating. Is there another option? How is it handled when the screed is inside?

I, on the other hand, would consider whether cooking on the island is necessary at all. Honestly, to me it seems like unnecessary frills that have become fashionable ever since cooking shows existed. A purely work island is much more sensible when you consider how much time is spent on preparations compared to the actual cooking process. Another aspect I would like to bring up is that island hoods/ceiling fans are more expensive than wall-mounted hoods. Just a suggestion.

A pure work island

We have planned that, but of course with electricity.

Yes, but electricity has to go there too....how do I solve the problem?
