what colour and pattern of tiles required for TV wall

Hello there, Please visit a tile studio of reputed brands like Kajaria/Somany/RAK rather than an ordinary tile dealer. You would get a better idea on materials, dimensions and colors. Since you have a large BUA, you could go for large format tiles for flooring of the sizes 1200 x 600 mm 800 x 800 mm Anything bigger than that would be a sheer loss in case of breakage and maintenance as well. Regards, Aurum Ideas and Spaces.

Hello Saj shk, Always avoid using high gloss as oil stains are more prominently seen in such surface. Your grey laminate is too dull and shabby to be used in an area where you need more lively effect. Try to go for different combination. Now a days acrylic sheets are available with great finish and good colours and it is 90degree bendable so joints are smooth and finished. Design the o.h. cabinets in such a way that you utilise total height of the kitchen and Use profiles for the same.
