Q. Stone tiles for construction material?

For Public toilet bath rooms kitchen etc. we may be use stones tiles ( marble , kota stone , Polished Kuddapa stone or polished Dhura stone. )
The water sinks at water points may be provided with marble. At other important station counters for Booking windows can be done with black marble . marble should not be used where cleaning is likely to be done by acid.

For water points on Plat form may be lined with cheaper polished stones.
