@ 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.

Hello , I just checked dealers for Simpolo and it has names I already visited. still if you have any design number for Simpolo or Sunheart it can help. Thanks for your response

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.
