Dear all.

How much $$ should I prepare for a condo kitchen renovation?
The kitchen is the size of a small room (separate part in the house) and not combined with the living room like many modern condos.
I am interested to know:

1) Estimate on the cost for removing tiles/knocking in kitchen
2) Do you suggest redoing the wiring (the house is 20+ years)? If it's necessary, why? How much does it costs?
3) Replace all the kitchen piping? How much does it cost estimately?
4) Any ideas for kitchen tiles and the wall?

Thank you so much guys,,,
