I have also already inquired with two local companies, they were also turnkey at about 2200. If we did not provide so much of our own work, we would also almost reach this price. I think that is roughly about right.
I am at
Estrich 7000
Interior doors 3000
Sanitary bathroom 10000
Sanitary WC 5000
Paint 2000
Lighting/Other 3000
165sqm divided into
50sqm tiles 3000
Rest cheaper coverings 4000
Waste like glue and moldings should be included. Possibly insurance for construction helpers and food/contribution for them.
Some equipment can be borrowed, some bought.
So except for the bathroom and toilet, I agree with the list. But 15,000 for the bathroom and toilet seems extremely high to me, there are only 2 showers, 1 bathtub, 2 toilets and 2 sinks. The connections are included in the offer, only the bathroom ceramics are not..
That doesn’t have to cost much either. Good toilet, 70 each, sinks matching that also 70. Two shower trays, 110 each. One bathtub, don’t know. Two toilet paper holders from Ikea and the brush thingy with it 14.50. Two rain showers Ikea, 99 each, Godmorgen mirror cabinet and base cabinet, see Ikea. Will never come to 15 grand. And you can clean yourself. For wellness we go to the sauna.
I consider it more important that you keep an eye on the additional costs. Material in the form of doors, etc. can still be influenced by not choosing the best. The [Abwasserverband], on the other hand, will insist on its connection fees.
