Hahahaha...bhai main constructor tu ni hoan.... But jo tiles hoti hian... from shop you get it in meters... I guess 40 meter tiles for walls and 10 meter for floor..
Dont go for the chinese tiles.. they dont have gurante... I used the white tile... i dont know what happened after few weeks.. there were some craks in each tile and the shop keeper didnt admitted that there is fault in tile.
Buy the Master tiles .. they have good repute... and start from 500 Rs meter goes upto 2000-3000 Rs meter
