It may well be that my ideas don't fit at all. Then we can talk about it and clarify.
I already wrote that the prices are realistic.
You wonder: you write about baths and showers up to the ceiling, including the tiles, and want that for free.
How do you come to the idea that the tiler would simply extend a calculated job without further payment?
Also the tiles: simply €50 instead of €30...
That’s an extra charge of €2,000 for 100 sqm.
That goes beyond any understanding, sorry.
It’s comparable to buying a car:
New car, VW, small engine, average equipment for €19,900... the car is not available with the comfort package, only winter package. Some options can be ordered.
Now you take that, but actually want the T-Roc. You order options like special paint, sports seats, fat tires and the navigation system, all worth €4,000.
Would you ask whether the navigation system for €1,800 is legitimate? Would you expect VW to give you the special equipment for free? It’s not a diesel ;)
And now think about how your question comes across here.
Regarding the notes: if I came across as judgmental, I didn’t mean that.
It’s simply different to build with an architect or general contractor: if you order a KfW55 house, the general contractor owes you that. Then heating and insulation will be designed accordingly. The blower door test is then the confirmation. If the value is not right, further work is done.
Your telephone socket is accounted for with the living room.
What’s more: to the electrician about €5,000, if you upgrade everywhere typically like a man
(Others do KNX right away)
To the plumber approx ... well, that can be €1,000, but also €10,000.
Same for the tiler: he will finish the corners with plastic. If you want stainless steel, then extra charge.
Yes, and the earthworks, you have to see if anywhere is limited to a depth of 30 cm.
