Can you explain what spacer tiles are? Without knowing what they are, I should mention that wallpaper always needs to be applied to a flat smooth surface, over top of a layer of sizing to help it stick.

Shivam Some more details will be required to suggest u accurate.Like floor plan, other finishes which u have thought of.Please feel to contact on 9702037999 Regards Rachna

You can go for Kajaria or Simpolo vitrified tiles they have a good quality and lot of range.

white tiles look stunning with a navy kitchen. Navy and white are very pretty together, but a touch of wood, like a couple of open woody shelves will add a touch of warmth to the overall 'corporate' look of blue and white. If not that, add a splash of yellow accessories
