Well, the tiles, which also often cost €50 in specialty stores (which really isn't hard), are exactly what compared to the parquet? They’re the same. Both “luxury.”
If you take wide plank floorboards or other large formats/patterns, then luxury.
P.S. Click vinyl from Bauhaus also often costs €35. So much for cheap goods.
I also don’t know if the floor coverings always “make a big difference.”
As a rule, almost no one reaches for the €10 laminate from the hardware store (at least not for living spaces, etc.).
Whether €50 for the tile or €60 for parquet (or maybe even the other way around?) is not particularly decisive either...
What matters is the amount of luxury and especially the decision for “big” cost factors like the size of the house, basement, controlled residential ventilation, garage, large photovoltaics, fireplace + stove, windows and doors, staircase...
With the other things, you can then save and see what you want.
