I renovated the kitchen and bathroom at my bar. The tile averaged out to about 60 RMB/sqm (shopped around a lot outside the city, prices inside the city will be at least 30% higher). The labor for tiling the kitchen and the bathroom floors and walls (in total about 25 sqm) I roughly estimate to be about 1000 RMB.
Grout will cost a couple hundred.
Rubbish disposal depends on how much you have, but will probably be another couple hundred.
Drop ceiling for the kitchen and bathroom was about 900 for materials and installation.
It varies greatly depending on your materials and exactly what type of job needs to be done.
