Tiles, vinyl, or other types of flooring with underfloor heating?

Laminate would now also be my favorite, as it hardly causes any craftsmanship problems (the areas at the edge would have to be cut) and laminate floors are relatively inexpensive if you take a look at the building materials available on the market!

We install as follows: bathrooms, hallway on the ground floor, utility room tiles. Open kitchen/living area design flooring (vinyl) from Classen, bedroom and hallway upstairs carpet.
Everything is a matter of taste

We had laminate flooring for years in all imaginable variants. Only those who see the dust bunnies scurrying know that even antistatic laminate needs to be vacuumed daily. Then it might as well be carpet. It is warmer and more comfortable underfoot.

...as easy to install as laminate but with a body-warm surface (when you lie on it, for example, it absorbs your body heat)...

I don't want to be a smart-ass but I am anyway
If a material absorbs heat from the body when touched, it does not feel warm; on the contrary, it actually draws heat away from the body.

So we are currently planning parquet in the living/dining room and kitchen, vinyl for the bathroom. What do you think about vinyl in the bathroom? I just think it looks elegant...

We had also considered it. Looks great.

: Do you actually install parquet in the kitchen? Aren't you worried about maintenance and liquids in the kitchen? Lacquered parquet that is glued down, or click parquet?
