@ Divya Sreedar. You will have to contact all of the ceramic boutiques that deal with imported tiles in Chennai. Attached below is a photo from AMSET ONE store in trivandrum with the subway tiles on display as I have seen. It takes 3 weeks to arrive from order date. If you like us to deal with the purchase please contact us or you could call them directly to find out.

Tiles can start from 50 rs/sqft, depending on what you want to apply. Kitchen slab, granite starts from 60-70 rs/sqft and the lighting for the ceiling starts around 350 per piece, depends n your ceiling design. This is the rough estimate of all of th items listed :)

How can I contact you sir?

Greetings from Dream Design, As per your inputs we suggest some ideas -Don't go with too dark backsplash as it will make the kitchen dull after some time and kitchen will look smaller -You can go with marble/tile or even the same counter top like quartz if you use in counter top you can same also put in backsplash as currently it's in trend -take white color with some black/grey lines marble or quartz -or you can go with white designer lines with grooving Sharing some reference pictures
