NEW! Granstone is now one of the only fabricator in Ottawa offering Dekton, the new and innovative ultra-compact surface. This space age material employs sinterized particle technology, a revolutionary high tech process that recreates the metamorphic change that natural stone undergoes when subject to high temperatures and pressure over thousands of years.

The resulting surface is clean and nice to touch and resistant to the daily grind that takes place in a kitchen over years of use. It is an ultra-sophisticated material for busy everyday life, capable of creating spaces that make the day to day preparation of food a pleasant experience that precedes the pleasure of sharing a meal with friends or family. Come see for yourself the wide range of colors and options Dekton offers.
