That's the result of hiring unprofessional contractors. Customers often hire cowboy builders for a better price, but this was not the case. They hired a reputable construction company that charged the client big money. The tiling work was subcontracted to a granite worktop company. Big mistake, you never hire a granite worktop company to install your natural stone tiles, just because they work with granite slabs. That alone does not qualify them as professional natural stone tilers. They are not tilers after all. Big difference. See the results!
