I thought that I remembered seeing 8 inch square wall tiles in the past here in Chiang Mai. I've gone to all of the places I've bought tile from before and the other usual places but this size is not to be found. The smallest I see now is 10 x 12 inch in size. Is my memory faulty or do they no longer make or sell this size wall tile? I'll admit it has been quite a while since I looked for tile. Has anyone seen this size recently?

Just one result via Google search ...

Did you try Home Sukkapan?  How about that big building supply store, Boontavorn?, on the super on the way to Lampun, on the left side after the Isuzu Don Jan?  Seen small sizes at both places, 4X4 and up.

Have already tried Thai Watsadu and Home Sukkapan. Forgot about Boonthavorn so will try them tomorrow. Suggestions much appreciated.

If you ask an employee you may receive incorrect information even if you show them a picture.  Lots of employee turnover and very large variety of stock.

 

After being told no have, I often find what I wanted after wondering around or asking a second or third employee.
